Successful treatment of xanthoma disseminatum with pulsed dye laser: A case report.

Xanthoma disseminatum is a rare form of non-Langerhans cell histiocytosis with limited treatment options due to its unknown aetiology and diffuse skin lesions. This case report presents the successful treatment of a 31-year-old male with severe pan-facial xanthoma disseminatum lesions following a facial burn and traumatic brain injury resulting from a car accident. After 5 sessions of monthly pulsed dye laser treatment, there was a clinically significant reduction in the lesions. Over the course of 3 years, the patient underwent a series of monthly pulsed dye laser treatments, and the lesions were almost cleared. These findings suggest that pulsed dye laser therapy may offer an effective treatment option for managing xanthoma disseminatum. This is the first report on use of the pulsed dye laser for treatment of xanthoma disseminatum.

Cutaneous Photoaging: A Notable Pattern of Distribution of Lentigines on the Face.

Importance: Facial lentigines are a common patient complaint encountered in general and cosmetic dermatology practices. Lentigines are a marker of photoaging and understanding their distribution will provide insight into the aging process in order to better counsel patients. Objectives: To compare the relative distribution of lentigines in facial cosmetic subunits. Methods: We reviewed clinical photographs of patients receiving Alexandrite laser treatment for facial lentigines during the time period 11/1/2017-12/1/2018. Individual lentigines were plotted for each patient into one of 21 aesthetic units. A "heat map" was created to compare the relative density of these lesions. Results: Grouped peripheral cosmetic subunits contained more lentigines compared to grouped central cosmetic units. The mean number of lentigines in the central units was 0.60 and in the peripheral units was 0.85. This finding was statistically significant with a p value of 0.0001.

Efficacy and Safety Evaluation of Picosecond Alexandrite Laser with a Diffractive Lens Array for Treatment of Melasma in Asian Patients by VISIA Imaging System.

Objective: To evaluate the efficacy and safety of picosecond (ps) 755-nm alexandrite laser with a diffractive lens array (DLA) generating laser-induced optical breakdown, which may be beneficial for melasma treatment. Background: Melasma is notorious for difficult to treat with any modality setting. Recently, picosecond alexandrite laser with DLA seems promising for dealing with it without intolerable complications. Methods: Twenty (N = 20) Asian female melasma patients with Fitzpatrick skin type IV were recruited for 3 treatment sessions of picosecond 755-nm alexandrite laser with DLA at a 4- to 6-week interval. The pulse duration was 750 ps. An 8-mm spot size and the fluence of 0.4 J/cm2 was used over the target area with 2 passes per treatment area and around 2000-2500 passes in total. The repetition rate was 10 Hz. Melasma Area and Severity Index (MASI) score and VISIA® imaging system analysis were utilized for evaluation before treatment and 4 weeks after the completion of the third treatment session. The clinical improvement and adverse events were assessed by the physicians and patients, respectively. Results: The median age of the patients was 45 years (from 27 to 55 years). In the physicians' evaluation, 40% (n = 8) of patients showed good improvement and 40% (n = 8) of patients showed moderate improvement. The mean MASI score before and after laser therapy showed significant improvement from 9.0 ± 4.8 to 6.5 ± 3.7 (p < 0.001). VISIA analysis of the forehead presented significant improvement in spots (p = 0.007) and porphyrins (p = 0.032). Some patients experienced erythema (25%), pruritus (20%), and scaling (20%) but subsided within few days of using emollients and sunscreen. Only 5% (n = 1) of patients developed mild postinflammatory hyperpigmentation, which also subsided in 3 weeks. Conclusions: Three sessions of picosecond 755-nm alexandrite laser with a DLA were effective for melasma treatment in Asian patients with minimal side effects.

Decreased phototherapy effectiveness on lower body.

Although phototherapy is an effective treatment for many dermatological conditions on the face, trunk, and proximal extremities, a common issue plaguing whole-body phototherapy is its diminished efficacy on the legs. In this commentary, we elaborate on the factors underlying this phenomenon, as well as potential solutions to improve treatment success.

Comparative effectiveness of purpuragenic 595 nm pulsed dye laser versus sequential emission of 595 nm pulsed dye laser and 1,064 nm Nd:YAG laser: a double-blind randomized controlled study.

INTRODUCTION: Erythematotelangiectatic rosacea is a common condition in Caucasians. The most frequently used lasers to treat this condition are pulsed dye laser (PDL) and neodymium:yttrium-aluminum-garnet laser (Nd:YAG). This study compares the treatment efficacy of purpuragenic PDL with that of sequential emission of 595 nm PDL and 1,064 nm Nd:YAG (multiplexed PDL/Nd:YAG). METHODS: We performed a prospective, randomized, and controlled split-face study. Both cheeks were treated, with side randomization to receive treatment with PDL or multiplexed PDL/Nd:YAG. Efficacy was evaluated by spectrophotometric measurement, visual photograph evaluation, the Dermatology Quality of Life Index questionnaire, and a post-treatment questionnaire. RESULTS: Twenty-seven patients completed the study. Treatment was associated with a statistically significant improvement in quality of life (p < 0.001). PDL and multiplexed PDL/Nd:YAG modalities significantly reduced the erythema index (EI; p < 0.05). When comparing the degree of EI reduction, no differences were observed between the two treatment modalities. PDL was associated with a higher degree of pain and a higher percentage of purpura. Multiplexed PDL/Nd:YAG modality was associated with fewer side effects and greater global satisfaction, and 96.3% of the patients would recommend this treatment to a friend. CONCLUSIONS: Both laser modalities are efficacious in the treatment of erythematotelangiectatic rosacea. The multiplexed PDL/Nd:YAG modality was preferred by the patients.

Effectiveness of Combining High-Intensity Focused Radiofrequency and Non-Ablative Fractional Laser for Improving the Appearance of the Aging Face and Neck

Background: The safety and effectiveness of high-intensity precision radiofrequency (RF) for rejuvenating the aging neck and face, and of fractional laser therapy for treating photodamaged skin have each been previously demonstrated. Objective: To assess the effects of combining high-intensity precision RF and fractional laser therapy for treating the aging face and neck. Methods and Materials: Subjects (N=19) with Fitzpatrick skin types I to VI and mild-to-moderate solar elastosis and sun or age-related pigmentation on the face and/or neck were sequentially treated with high-intensity precision RF and fractionated laser devices during the same session. Three sessions were completed 30 days apart. Assessments were made 90 days after the last treatment. Results: Both Clinician and Subject Global Assessment of Improvement scores indicated clinical improvement (n=16, 84%) or no change (n=3, 16%) in skin quality. Clinical improvement was also observed in 16 subjects (68%) in masked assessment. Most subjects (90%) noted improved skin quality and 74% expressed at least some satisfaction with their treatment results. The most common adverse events were erythema (n=57, 45%) and edema (n=45, 35%). Conclusion: The results of this study establish the safety and effectiveness of combined treatment with a 1927 nm thulium laser and a high-intensity precision RF device.

Clinical Evaluation of Safety and Efficacy of Fractional Radiofrequency Facial Treatment of Skin Type VI Patients

INTRODUCTION: It has been well established that patients with darker skin types (Fitzpatrick skin types IV-VI) have an increased incidence of thermal induced side effects from laser and radio frequency (RF) treatments. Complications include a higher risk of post-inflammatory hyperpigmentation, hypopigmentation, and scarring, leading to unsatisfactory clinical outcomes. Fractional technologies improve the safety when treating patients with skin of color by treating only fractions of the skin while leaving a healing reservoir of untreated skin that improves the healing process. Fractional RF tips with coated pins may offer a more advantageous safety profile, particularly in the skin-of-color population (Fitzpatrick skin types IV-VI) by increasing the protection of the epidermal layer by minimizing epidermal heating The current study was intended to evaluate the safety and efficacy of fractional RF technology for the treatment of patients with Fitzpatrick skin type VI. METHODS: 35 subjects with skin type VI received 3 sessions of facial treatments, 4 weeks apart using a fractional RF device with 24 pin coated tip. The treatment's safety and efficacy were evaluated at 2 follow-up visits, 6 and 12 weeks after the last treatment. RESULTS: Skin characteristics evaluations, including Fitzpatrick Wrinkles Classification, acne scars, and overall facial appearance demonstrated improvement in follow-up visits comparing to baseline. No significant unexpected adverse events were detected. CONCLUSION: The current study proves the safety and efficacy of the fractional RF treatment modality with coated pins tips for skin rejuvenation treatments resulting in improved wrinkles, acne scars, and overall skin appearance, in patients with skin type VI.

Use of a novel 589-nm solid-state laser for treatment of facial erythema.

OBJECTIVE: To evaluate the efficacy and safety associated with use of a 589-nm solid-state laser for treatment of facial erythema. METHODS: A prospective, IRB-approved study was conducted. Participants who were interested in treatment for facial erythema were recruited. They received four monthly treatments with the 589-nm laser. Erythema of the right and left face was graded on a scale of 0-4, 4 being most severe, by both investigators and participants prior to each treatment and at follow-up. Safety was assessed by any reported side effects. RESULTS: Twenty-four participants enrolled in the study, 16 women (67%) and 8 men (33%), with an average age of 51.1 years. Investigator grades showed a statistically significant improvement in erythema of 31% for both the right and left face. Participant grades showed a statistically significant improvement in erythema of 23.2% for the right face and 22.8% for the left face. Side effects were limited to transient erythema posttreatment. CONCLUSION: A 589-nm solid-state laser achieved a modest improvement in facial erythema when evaluating results 1 month after four monthly treatments. No major safety issues were reported.

Facial nevus depigmentosus getting remarkable repigmentation by treatment with a 308-nm excimer laser: A case report.

Nevus depigmentosus (ND) is a rare, congenital, nonprogressive depigmented lesion with irregular outline. To date, the few therapeutic approaches that have been developed to treat ND have yielded unsatisfactory results. We reported on a 6-month-old girl who presented with a ND on the right side of her face for 5 months. Treatment with a 308-nm excimer laser was started once a week at 300 mJ/cm2 and then was increased by 50-100 mJ/cm2 in each subsequent session until post-treatment erythema occurred. After 10 treatments, repigmentation in the lesion was evident and remained stable 1 month later at follow up. This case supports that the 308-nm excimer laser may be a good choice for the treatment of ND.

Comparison of efficacy between long-pulsed Nd:YAG laser and pulsed dye laser to treat rosacea-associated nasal telangiectasia.

BACKGROUND: Rosacea is characterized by erythema on face, especially erythema and linear telangiectasia on the nose. Currently, various vascular lasers are used for treatment, and among them, are long-pulsed Nd:YAG(LPNY) and pulsed dye laser (PDL). OBJECTIVES: This study compared the efficacy of LPNY and PDL in treating rosacea-associated nasal telangiectasia. METHODS: Patients with rosacea who showed erythema and telangiectasia on the nose were included. Each patient was treated with PDL on the left side of the nasal bridge, and LPNY on the right side, three times with 4-week intervals. At the end of the treatment, two independent dermatologists evaluated overall treatment response compared with baseline. RESULTS: The physician's assessment of treatment concluded that good improvement was seen in six PDL and seven LPNY patients, and excellent improvement five PDL and four LPNY patients. There was no significant difference (p = 0.62, 95%CI) between the groups. Overall improvement was similar; however, LPNY induced a greater response in thick, dilated vessels, while erythema with mild telangiectasia was more responsive to PDL. CONCLUSION: Both LPNY and PDL are effective in treating rosacea-associated nasal telangiectasia. If LPNY is used properly to avoid side effects with careful consideration, it can also be used as a good modality.

Keloid Skin Flap Retention and Resurfacing in Facial Keloid Treatment.

OBJECTIVE: Facial keloids commonly occur in young patients. Multiple keloid masses often converge into a large lesion on the face, representing a significant obstacle to keloid mass excision and reconstruction. We describe a new surgical method that excises the keloid mass and resurfaces the wound by saving the keloid skin as a skin flap during facial keloid treatment. METHODS: Forty-five patients with facial keloids were treated in our department between January 2013 and January 2016. Multiple incisions were made along the facial esthetic line on the keloid mass. The keloid skin was dissected and elevated as a skin flap with one or two pedicles. The scar tissue in the keloid was then removed through the incision. The wound was covered with the preserved keloid skin flap and closed without tension. Radiotherapy and hyperbaric oxygen were applied after surgery. Patients underwent follow-up examinations 6 and 12 months after surgery. RESULTS: Of the 45 total patients, 32 patients were cured and seven patients were partially cured. The efficacy rate was 88.9%, and 38 patients (84.4%) were satisfied with the esthetic result. CONCLUSION: We describe an efficacious and esthetically satisfactory surgical method for managing facial keloids by preserving the keloid skin as a skin flap.

Prospective studies of the efficacy and safety of the picosecond 755, 1,064, and 532 nm lasers for the treatment of infraorbital dark circles.

BACKGROUND: Infraorbital dark circles result from a combination of factors. The fractionated picosecond 755 nm alexandrite laser and dual wavelength picosecond Nd:YAG laser have not been examined as a method of addressing infraorbital hyperpigmentation. OBJECTIVE: To determine the efficacy and safety of treatment of infraorbital dark circles using fractionated picosecond 755 nm and dual wavelength picosecond Nd:YAG laser. METHODS AND MATERIALS: These trials did not utilize a comparative design; rather, these were separate, prospective, open-label, evaluator-blinded trials utilizing two treatment regimens: (i) 19 adult subjects were treated in a single session with the dual wavelengths of 532 nm and 1,064 nm in consecutive passes using the fractionated lens; (ii) 10 adult subjects were treated using the picosecond 755 nm laser via the fractionated lens in three treatment sessions at 3 week intervals. Subjects in both studies were followed-up for blinded-investigator assessment of infraorbital hyperpigmentation, adverse events, and improvement compared to baseline. RESULTS: The dual wavelength picosecond Nd:YAG laser, blinded-investigator assessment did not demonstrate a significant improvement in infraorbital hyperpigmentation at day 60 (P = 0.16). The picosecond 755 nm alexandrite laser significantly improved infraorbital hyperpigmentation by day 42, with improvement maintained through day 132 (P = 0.07 and 0.00001, respectively). Adverse events were mild and temporary. CONCLUSION: A single treatment with the fractionated picosecond 1,064/532 nm lasers did not produce a significant improvement in infraorbital hyperpigmentation. A series of three treatments with the fractionated picosecond 755 nm laser resulted in significant improvement in hyperpigmentation. Lasers Surg. Med. 50:45-50, 2018. © 2017 Wiley Periodicals, Inc.

Shorter Treatment Intervals of East Asians with Port-Wine Stain with Pulsed Dye Laser Are Safe and Effective-A Prospective Side-by-Side Comparison.

OBJECTIVE: To compare the safety and efficacy of pulsed dye laser (PDL) at different intervals for the treatment of East Asians with Port-Wine Stain (PWS). BACKGROUND: The population of East Asians around the world is about 1.6 billion, and they are considered to have more melanin in their skin compared with Caucasians. Nevertheless, no studies about the optimal treatment intervals for East Asians with PWS have been carried out. METHODS: We prospectively investigated 39 East Asian patients with untreated PWS. Half of the PWS lesion was randomly allocated to be treated at 3 weeks and the other half at 6 weeks. Both halves of the PWS were treated three times in total. The efficacy outcome 2 months post final treatment was evaluated by visual and chromameter evaluation. RESULTS: The average blanching rate was 40.27% and 44.17% for PDL treatments at the 3- and 6-week interval sites, respectively (p > 0.05). No patient developed scarring or permanent pigmentation change. LIMITATIONS: There was no age criteria involved in the enrollment of patients in this study. Additionally, there is no comparison with long-term treatments at different intervals. CONCLUSIONS: PDL treatment at 3-week interval proved to be safe for East Asians with PWS. This can reduce the total duration of the course of treatments and had no increase in side effects compared with the standard interval treatments.

Treatment of Photoaging With a Dual-Wavelength, 532 nm and 1,064 nm Picosecond-Domain Laser Producing a Fractionated Treatment Beam Using a Holographic Optic.

BACKGROUND: A dual-wavelength, picosecond-domain, fractionated laser delivering 1,064nm and 532nm laser energy through a holographic optic was investigated for safety and effectiveness at improving the appearance of chronic photoaging. MATERIALS AND METHODS: A total of 27 subjects were enrolled with 24 completing the study, and 14 subjects were treated with 1,064 nm and 10 with 532 nm. The 1,064 nm-treated subjects received 5 monthly treatments while the 532 nm-treated subjects received 4 monthly treatments. Improvement was measured by blinded evaluation of pre- and post-treatment images 12 weeks following the final treatment. Subjects also evaluated treatment effect and side-effects. RESULTS: Blinded reviewers correctly identified the baseline image in 52 of 72 paired images, or 72% of the time, with a mean improvement score of 1.4 using an 11-point rating scale (P less than 0.0001). Post-treatment erythema, mild edema, and petechiae were the only side effects noted. CONCLUSION: The fractionated, picosecond-domain, 532 nm and 1,064 nm laser is safe and effective for improvement of facial photodamage. The laser was well tolerated with mild erythema, edema, and petechiae as the most common side-effects.

A Retrospective Study on Efficacy of Pulsed Dye Laser and Intense Pulsed Light for the Treatment of Facial Telangiectasia.

Both pulsed dye laser (PDL) and intense pulsed light (IPL) systems have been demonstrated to be effective for treatment of facial telangiectasia, however there have been very few comparative studies between both treatments involving purely Asian patient populations. In this study, we performed a retrospective analysis to compare the efficacy of PDL and IPL systems for the treatment of facial telangiectasia. A total of 416 patients with facial telangiectasia who were treated by PDL or IPLs in our department from August 2012 to March 2015 were included in this study. The subjects received one of the following five treatments: PDL 595 nm (9-12 J/cm2), MaxG (500-670 nm & 870-1200 nm, 30-46 J/cm2), IPL (560-1200 nm, 18-24 J/cm2), M22 560 (560-1200 nm, 15-18 J/cm2), and M22 590 (590-1200 nm, 15-20 J/cm2). Each treatment had two sessions with 6-week intervals. The improvement percentage score in facial telangiectasia after the final treatment was evaluated by two non-treating physicians. We found almost all patients (less than 95.00%) had marked improvements or nearly complete clearance of the lesions after PDL 595 nm or MaxG treatment, as compared to 41.38%-56.58% patients in the other three groups that showed similar degrees of improvements. Both PDL 595 nm (9-12 J/cm2) and MaxG (500-670 nm & 870-1200 nm, 30-46 J/cm2) treatments resulted in significantly superior vessel clearance than the IPL systems with other wavelength bands (560-1200 nm or 590-1200 nm) and relatively lower fluence (15-24 J/cm2). Our results also suggested fluence levels account for the significant differences in the effectiveness delivered by different IPL systems. We concluded that PDL 595 nm and MaxG showed comparable clinical efficacy and both treatments resulted in most beneficial outcomes.

Treatment of Facial Acne Scarring With Fractional Carbon Dioxide Laser in Asians, a Retrospective Analysis of Efficacy and Complications.

BACKGROUND: Fractional carbon dioxide (CO2) laser resurfacing unites the idea of fractional photothermolysis with an ablative 10,600-nm wavelength. This technology permits effective treatment of acne scarring, with shorter recovery and a decreased side effect profile as compared to traditional CO2 laser resurfacing. OBJECTIVE: The aims of this study were to study the efficacy and safety of fractional CO2 laser for acne scars in Asian patients. METHODS: This was a retrospective study of all patients treated with the fractional CO2 laser for facial acne scarring between January 2, 2008, and December 31, 2010, at the National Skin Centre, Singapore. Data reviewed included sex, age, and severity of acne, type of scarring, previous treatment history, frequency of treatments, adverse events, and efficacy. RESULTS: Two hundred and ten fractional CO2 laser treatments for facial acne scars were performed on 107 patients (65 men and 42 women, Fitzpatrick skin Types II to V) during the study period. Sixteen of 107 patients experienced (15.0%) adverse events. The adverse events include hyperpigmentation (6.4%), blistering (4.0%), crusting (2.9%), aggravation of inflammatory acne lesions (1.7%), and scarring (0.6%). There were no reported side effects of hypopigmentation, bacterial or viral infection. Follow-up results after final laser treatment showed that 66.4% of patients reported Grade 1 skin texture improvement, that is, <25% (n = 71); 30.0% had Grade 2 improvement, that is, 25% to 50% improvement (n = 31); 3.7% had Grade 3 improvement, that is, 51% to 75% improvement (n = 4); and 0.9% had Grade 4 improvement, that is, >75% improvement (n = 1). CONCLUSION: The study demonstrated the efficacy and safety of a fractional CO2 laser in the treatment of acne scars in Asian. Future studies are required to establish optimum treatment parameters and achieve better clinical results.

In Vivo Investigation of the Safety and Efficacy of Pulsed Dye Laser with Two Spot Sizes in Port-Wine Stain Treatment: A Prospective Side-by-Side Comparison.

OBJECTIVE: Pulsed dye laser (PDL) with 7 and 10 mm spot sizes is widely used on a regular basis for the treatment of port-wine stain (PWS). BACKGROUND DATA: No studies have reported on the differences in efficacy outcomes resulting from the use of different laser spot sizes in the treatment of PWS by PDL. Thus, an in vivo investigation into the differences in safety and efficacy of treatment between two spot sizes (7 vs. 10 mm) of PWS by PDL was conducted. MATERIALS AND METHODS: A total of 35 PWS patients underwent three treatment sessions by using a 595 nm wavelength PDL (Vbeam®, Candela Corp) with two laser settings: (1) 7 mm spot size, radiant exposure of 12 J/cm2 and (2) 10 mm spot size, radiant exposure of 10 J/cm2. Cryogen spray cooling and 1.5 msec pulse duration were applied. Therapeutic outcomes were evaluated by visual and chromametric evaluation 3 months after the final treatment. RESULTS: Average blanching rates were 34.03% and 36.51% at sites treated by PDL with 7 and 10 mm laser spot sizes, respectively (p < 0.05). CONCLUSIONS: On the basis of the laser setting, the therapeutic outcomes of PDL with 7 and 10 mm spot sizes were similar. PDL with a 10 mm laser spot size is more efficacious with lower radiant exposure than PDL with a 7 mm spot size; it can also reduce the treatment time.

Retrospective analysis of the treatment of melasma lesions exhibiting increased vascularity with the 595-nm pulsed dye laser combined with the 1927-nm fractional low-powered diode laser.

BACKGROUND: Melasma presents a significant challenge to laser surgeons. Aggressive treatments often result in rebound melasma or post-inflammatory pigmentary alteration. Recent reports suggest melasma pathogenesis may have a vascular component. Spectrocolorimetry can detect subtle or sub-clinical telangiectatic erythema within melasma lesions. For certain patients identified by spectrocolorimetry, effective melasma treatment may include vascular-targeted therapy together with pigment-specific treatment modalities. Such combined therapies may reduce the likelihood of melasma recurrence. OBJECTIVE: To evaluate the efficacy of treating melasma lesions exhibiting subtle or sub-clinical telangiectatic erythema with the 595-nm pulsed dye laser (PDL) combined with the 1927-nm fractional low-powered diode laser (FDL). METHODS: A retrospective review was performed over a 2-year period as follows. Evaluated patients (n = 11) include 10 women and 1 man, average age of 38.7 years, and Fitzpatrick skin types II-IV. Each patient exhibited melasma lesions with subtle or sub-clinical telangiectatic erythema identified by spectrocolorimetry. Each underwent a series of treatments (average of four) at approximate 4-6 week intervals of the PDL followed by the FDL. Treatments were performed same-day, sequentially, with 10-15 minute interim time allowance for skin cooling. The following PDL parameters were utilized: 10 mm spot, 10-20 ms pulse duration, 7.5-8.5 J/cm2 fluence, 30/30 DCD. Eight passes with the FDL (Clear + Brilliant® Permea™, Solta Medical, Hayward, CA) were then performed utilizing a "low" treatment level. Clinical endpoint was mild erythema and edema. Patients were encouraged to practice strict photoprotection and apply topical skin lightening agents, but compliance was not measured. An independent physician evaluated photographs taken at baseline and at follow-up after last treatment session (average follow-up of 96 days). A quartile improvement score was used to grade the improvement of melasma and underlying telangiectatic erythema. At time of data analysis, patient satisfaction was self-graded on a three-point scale (0 = not satisfied, 1 = satisfied, 2 = very satisfied). RESULTS: Six out of eleven patients (54%) demonstrated greater than 50% improvement in melasma presentation. Improvement in melasma generally paralleled improvement in erythema. No rebound melasma, post-inflammatory changes, or adverse events were noted. Patient satisfaction responses averaged 1.6, with all (10) patients reporting 1 "satisfied" or 2 "very satisfied." CONCLUSIONS: Melasma lesions exhibiting subtle or sub-clinical telangiectatic erythema may be improved by combined vascular-targeted laser therapy together with fractional low-powered diode laser therapy. A parallel improvement in telangiectatic erythema suggests a relationship between the underlying vasculature and hyperpigmentation. There is a low risk of adverse effects and overall patient satisfaction is high. Follow-up to optimize treatment parameters and determine long-term durability is needed. Lasers Surg.
