Photodynamic Skincare: A Prospective Single-Center Study.

BACKGROUND: Peer-reviewed, clinical studies measuring the efficacy and usability of skin care products enhance their integrity and may guide experts in the field in providing recommendations. A single-blind, prospective clinical study was designed to assess the subject satisfaction, clinical benefit, and safety of three photodynamic topical formulations referred to as MMSRepose (MMSRep), MMSRevive (MMSRev), and MMSBalance (MMSB).  Methods: Thirteen male and female patients (mean age 49 +/- 17.8 years) applied one of the three topical serums twice daily over a period of 12 weeks. Subjects returned for photography, and blinded investigator evaluation of rhytides (fine lines) and dyspigmentation were measured on a 6- and 4-point scale, respectively. Patient-perceived efficacy of multiple clinical outcomes was measured on a 5-point scale.  Results: 100% of subjects reported at least a 1-grade improvement in global aesthetic at the conclusion of the study. Investigator assessment revealed an overall 53.3% decrease in rhytides, correlating to a mean point reduction from 1.65 +/- 0.77 to 0.77 +/- 0.53 (P<0.001) from baseline to week 12. Investigator assessment of dyspigmentation revealed a 62.7% decrease, correlating to a mean point reduction of 1.85 +/- 0.68 from week 1 to 0.69 +/- 0.48 at week 12 (P<0.001). CONCLUSION: Photodynamic serums demonstrate clinical efficacy in skin rejuvenation and high user satisfaction. There were no serious adverse events. This study is limited by the inability to randomize to placebo due to the small sample size, as subject retention was heavily impacted by the SARS-CoV-2 pandemic. Future studies may be indicated to undergo comparison with a larger cohort.  J Drugs Dermatol. 2024;23(5):332-337. doi:10.36849/JDD.7167.

Distinct Approaches to Perioperative Management of Anticoagulation and Antiplatelet Therapy among Providers Performing Cutaneous Surgery.

BACKGROUND: Despite increasing cross-collaboration between providers who perform cutaneous surgery, a disparity still exists in the current practices regarding perioperative management. This could lead to treatment delays, patient confusion, and increased morbidity, such as clotting, infection, and discomfort of patients. OBJECTIVE: To characterize the management practices of different providers in regards to perioperative anticoagulation and antiplatelet therapy for cutaneous surgery. METHODS AND MATERIALS: This study used an electronic survey to assess current perioperative management practices of dermatologic surgeons and plastic and reconstructive surgeons. RESULTS: 177 physicians (115 dermatologic surgeons and 62 plastic and reconstructive surgeons) responded to the survey. For all therapeutic agents, dermatologic surgeons were significantly more likely than their plastic and reconstructive surgery colleagues to continue all anticoagulant and antiplatelet agents perioperatively for cutaneous surgery (vitamin K antagonists, antiplatelets, LMWH, direct Xa inhibitors, direct thrombin inhibitors, NSAIDS: P<0.001; fish oil, vitamin E: P<0.01). CONCLUSION: Our data highlight the significant practice gaps that exist between dermatologic surgeons and plastic and reconstructive surgeons. Reducing this disparity will facilitate improved continuity of care, especially when patients are referred from dermatologic surgeons to plastic and reconstructive surgeons for more complex repairs, and potentially reduce morbidity and mortality associated with medication discontinuation.

A Prospective, Multicenter, Randomized, Evaluator-Blinded, Split-Hand Study to Evaluate the Effectiveness and Safety of Large-Gel-Particle Hyaluronic Acid with Lidocaine for the Correction of Volume Deficits in the Dorsal Hand.

BACKGROUND: Hand rejuvenation has become increasingly popular, but there are few reports published on the use of hyaluronic acid gels for correction of volume deficits in the dorsal hand. METHODS: This study evaluated the efficacy and safety of large-gel-particle hyaluronic acid with lidocaine, a 20-mg/ml hyaluronic acid gel with 0.3% lidocaine, compared to no treatment for the correction of volume deficits in the dorsal hand. This was a prospective, multicenter, split-hand study in 90 subjects who received treatment with product in one hand. The primary efficacy endpoint was based on a 1 point of improvement with treatment versus no treatment according to the Merz Hand Grading Scale at week 12. Other assessments included Central Independent Photographic Reviewers evaluations of hand photographs, Global Aesthetic Improvement Scale, subject satisfaction, and safety. RESULTS: The mean injection volume was 2.1 ml at the first treatment. Subjects demonstrated significantly higher response rates with treatment compared to no treatment at week 12 (85.9 percent versus 21.2 percent) and at weeks 16, 20, and 24 (p < 0.0001). Photographic Reviewers assessments showed consistently greater improvements in the treated hands compared with the untreated hands from week 12 to week 24. Most subjects and investigators (≥92.8 percent) reported improvements in Global Aesthetic Improvement Scale score across all time points with treatment. Treatment-related adverse events were reported in seven subjects (7.9 percent). Most of these were mild, and none were serious. CONCLUSION: Hyaluronic acid with lidocaine is safe, effective, and well tolerated for the correction of volume deficits in the dorsal hand. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, II.

Examining the Efficacy of Calcium Hydroxylapatite Filler With Integral Lidocaine in Correcting Volume Loss of the Jawline-A Pilot Study.

BACKGROUND: Patients seek 3-dimensional volume restoration of the jawline to obtain a "defined" line. Injection of filler into the jawline is not approved by the Food and Drug Administration; however, dermatologists have injected this area with positive results, minimal adverse events, and high patient satisfaction. OBJECTIVE: This study explores the efficacy of premixed calcium hydroxylapatite filler with integral lidocaine [CaHA(+)] to correct volume defects of the jawline. It examines the longevity, safety, and patient satisfaction (up to 12 months) of CaHA(+) for jawline volume loss correction. MATERIALS AND METHODS: This is a single-investigator, nonblinded study. Twenty subjects received CaHA(+) filler injection in the jawline, with follow-up evaluations conducted at 14 days, 6 weeks, and 3, 6, 9, and 12 months. RESULTS: CaHA(+) injection in the jawline results in statistically significant restoration in volume and improvement in appearance lasting up to 12 months. Overall, subjects report "moderate" improvement on the Global Aesthetic Improvement Scale. CONCLUSION: It is important for cosmetic surgeons and dermatologists to have access to data on the efficacy and safety of injectables. The data obtained in this study show that CaHA(+) is an effective and safe option to correct jawline volume loss and is associated with high patient satisfaction.

BACKGROUND: The cosmeceutical industry is an ever-growing and in demand market, especially in Asia. Korea has been on the forefront of creating the newest generation and most innovative cosmeceuticals products including ingredients such as snail secretions, starfish powder, botanical extracts, green tea, and red ginseng. Given their increasing prevalence in the cosmeceutical industry, scientists have been conducting investigations into these extracts and their properties. OBJECTIVE: To summarize the current literature surrounding multiple natural ingredients found in Korean cosmeceutical products. METHODS: A review of the literature surrounding natural ingredients found in Korean cosmeceuticals was conducted using PubMed (U.S. National Library of Medicine). RESULTS: Multiple natural extracts have been found to have antiaging, antitumor, and antimelanogenic effects making them useful additives in current cosmeceutical products. CONCLUSION: With the public's increasing awareness of cosmeceutical products, it is important for physicians to understand the properties of these extracts in order to inform patients correctly and ensure patient safety.

Pilot Study Examining the Safety and Efficacy of Calcium Hydroxylapatite Filler With Integral Lidocaine Over a 12-Month Period to Correct Temporal Fossa Volume Loss.

BACKGROUND: Age-related volume loss in the temporal fossae is due to thinning of the epidermis, loss of subcutaneous structural volume, and change in the bony architecture. Temporal concavities are important areas of 3-dimensional volume restoration. The temporal fossae is becoming an increasingly popular area for patients seeking soft tissue augmentation with injectable fillers such as calcium hydroxylapatite with integral lidocaine [CaHA (+)]. OBJECTIVE: This pilot study aims to define the safety, efficacy, technique, and patient-reported outcomes for injectable CaHA (+) to correct volume loss in the temporal fossae over a 12-month period. MATERIALS AND METHODS: This was a single-investigator, nonblinded study involving 20 participants. Participants received filler injection into their temporal fossae, with follow-up evaluations at Day 14, 6 weeks, and 3, 6, 9, and 12 months. RESULTS: CaHA (+) results in statistically significant improvement in temporal fossae appearance lasting up to 12 months. Subjects reported "moderate" global aesthetic improvement over the 12-month period. CONCLUSION: As the cosmetic field continues to advance, it is important for practitioners to have access to research regarding the efficacy and safety of injectables. These results show that CaHA (+) is an effective and safe option to correct temporal fossae volume loss associated with high patient satisfaction.

Energy-Based Devices in Male Skin Rejuvenation.

Men seek cosmetic procedures for vastly different reasons than women. Men often seek discrete cosmetic services with little downtime. Male skin structure generally differs from female skin structure. Dermatologists should consider subtle differences in the psyche of the male cosmetic patient.

Recall erythema phenomenon following Er:YAG laser treatment: two case studies and literature review.

Recall erythema is a phenomenon occurring when an area of epidermis treated with laser is later exposed to a trigger, most often sunlight or hot water, causing erythema in the zone of laser treatment after post-treatment erythema has already resolved. Radiation recall dermatitis is a more specific subtype of recall erythema in which an area treated with radiation is subjected to another exposure causing erythema in the area of previous radiation. Cases of recall dermatitis after laser treatment are extremely rare and have only been reported with diode neodymium-doped yttrium aluminum garnet lasers. We report two cases of recall dermatitis following erbium-doped yttrium aluminum garnet resurfacing laser triggered by exposure to either hot water or direct sunlight, and in one case, radioablation of the thyroid gland. We will also provide a brief literature review of recall dermatitis in the setting of laser surgery.

A review of available laser and intense light source home devices: A dermatologist's perspective.

BACKGROUND: Home optical devices are becoming an increasingly popular treatment modality sought out by patients for dermatologic pathologies such as acne, hair removal and anti-aging, as these devices are a low-cost and convenient therapy choice. METHODS: An Internet search using PubMed.gov was completed with search terms, "home device dermatology," "home device acne," "home device hair" or "hair removal," and "home device aging." RESULTS: Currently, there are multiple home optical devices available on the market. These devices have been approved for the treatment of acne, scars, hair removal, and wrinkles using intense pulsed light, light-emitting diode, heat, infrared, low-level light therapy, and laser. Although studies on home devices are limited, current dermatologic literature shows that these devices are promising with significant post-treatment results as well as a high level of safety. CONCLUSIONS: Home optical devices are mostly used without medical practitioner supervision. As home devices usually deliver less energy per session than with professional treatments, it is important that consumers are given realistic expectations of post-treatment outcomes. Patients may use home devices without disclosure to their physician and it is important as healthcare professionals to be aware of the existence of these devices, how to use the devices properly (including what diseases can be treated and which skin types are considered safe for use), as well as any adverse effects that may occur. New research endeavors are being completed to explore the used of home devices for the treatment of chronic inflammatory diseases such as psoriasis.

The Kinetics of Reversible Hyaluronic Acid Filler Injection Treated With Hyaluronidase.

BACKGROUND: Hyaluronidase is an enzyme capable of dissolution of hyaluronic acid (HA). There is a lack of evidence-based research defining time- and concentration-dependent reversal of HA filler using hyaluronidase. OBJECTIVE: To explore the efficacy of different concentrations of hyaluronidase in digesting commercially available HA-based reversible fillers-Belotero Balance (BEL), Juvederm Ultra XC (JUVXC), Juvederm Ultra Plus (JUVX+), Juvederm Voluma XC (JUVV), Restylane-L (RESL), Restylane Silk (RESS), and Perlane/Restylane Lyft (RESLYFT). MATERIALS AND METHODS: This was a blinded randomized study involving 15 participants. Participants received HA filler injection into their back, followed by no secondary injection, or injection with normal saline, 20 or 40 units of hyaluronidase. Using a 5-point palpation scale, the degradation of HA filler was monitored over 14 days. RESULTS: In the authors' study, there is a significant decrease in HA filler degradation using 20 and 40 units of hyaluronidase compared with no secondary injection or normal saline. There is no significant difference in HA filler dissolution when comparing 20 to 40 units of hyaluronidase. CONCLUSION: Lower concentrations of hyaluronidase may be just as effective as higher concentrations to degrade HA filler in situations where the reversal of cutaneous augmentation with HA filler arises.

The Two Faces of Fractionated Photodynamic Therapy: Increasing Efficacy With Light Fractionation or Adjuvant Use of Fractional Laser Technology.

"Fractionated photodynamic therapy (PDT)" is a new term being used by dermatologists to describe advances in PDT technology including fractionated light or the adjuvant use of fractional lasers. Although dermatologists have used PDT since the early 1990s for the treatment of photodamage and precancerous lesions, newer developments in technology have allowed for the treatment of non-melanoma skin cancers (NMSCs), in ammatory disorders, and even uses in the eld of anti-aging. Recent developments in fractionated light therapy have allowed for PDT with dark intervals and two-fold illumination schemes to increase cellular damage and apoptosis. Combining PDT with fractional laser technology has allowed for enhanced dermal penetration of topical photosensitizers including 5-aminolevulinic acid (ALA) and methyl aminolevulinate (MAL), as well as increased ef cacy of treatment. These advances in PDT technology will allow for increased convenience, decreased treatment time, only one application of topical photosensitizer, and decreased cost to the patient and dermatologist.

HYC-24L Demonstrates Greater Effectiveness With Less Pain Than CPM-22.5 for Treatment of Perioral Lines in a Randomized Controlled Trial.

OBJECTIVE: This trial compares the effectiveness and safety of HYC-24L (Juvéderm Ultra XC; Allergan plc, Dublin, Ireland) (24 mg/mL of hyaluronic acid, 0.3% lidocaine) and CPM-22.5 (Belotero Balance; Merz Aesthetics, Raleigh, NC) (22.5 mg/mL of hyaluronic acid) for the treatment of perioral lines. MATERIALS AND METHODS: Men and women aged 35 years or older with moderate-to-severe perioral lines were recruited for this randomized controlled, rater-blinded, 2-arm trial. The primary endpoint was a comparison of rater-assessed responder rates by the validated 4-point Perioral Lines Severity Scale at Month 6; responders were those who showed a ≥1 point improvement. A secondary endpoint was subject-assessed change in perioral lines measured by the Global Assessment of Change Scale. RESULTS: A total of 136 subjects received treatment and 132 completed the trial (mean age: 58 ± 8 years). Total volume injected was 1.18 mL (HYC-24L) and 1.32 mL (CPM-22.5). At Month 6, a significantly greater proportion of HYC-24L subjects responded to treatment (87%) than CPM-22.5 subjects (72%) (p < .04). At all time points, HYC-24L subjects reported significantly greater improvement in their perioral lines than CPM-22.5 subjects, with the greatest difference at Month 6. No unexpected adverse events occurred. CONCLUSION: HYC-24L subjects showed a higher response rate and a greater improvement in their perioral lines than CPM-22.5 subjects for up to 6 months.

Temporal fossa defects: techniques for injecting hyaluronic acid filler and complications after hyaluronic acid filler injection.

Facial changes with aging include thinning of the epidermis, loss of skin elasticity, atrophy of muscle, and subcutaneous fat and bony changes, all which result in a loss of volume. As temporal bones become more concave, and the temporalis atrophies and the temporal fat pad decreases, volume loss leads to an undesirable, gaunt appearance. By altering the temporal fossa and upper face with hyaluronic acid filler, those whose specialty is injecting filler can achieve a balanced and more youthful facial structure. Many techniques have been described to inject filler into the fossa including a "fanned" pattern of injections, highly diluted filler injection, and the method we describe using a three-injection approach. Complications of filler in the temporal fossa include bruising, tenderness, swelling, Tyndall effect, overcorrection, and chewing discomfort. Although rare, more serious complications include infection, foreign body granuloma, intravascular necrosis, and blindness due to embolization into the ophthalmic artery. Using reversible hyaluronic acid fillers, hyaluronidase can be used to relieve any discomfort felt by the patient. Injectors must be aware of the complications that may occur and provide treatment readily to avoid morbidities associated with filler injection into this sensitive area.

Pivotal ERIVANCE basal cell carcinoma (BCC) study: 12-month update of efficacy and safety of vismodegib in advanced BCC.

BACKGROUND: Primary analysis from the pivotal ERIVANCE BCC study resulted in approval of vismodegib, a Hedgehog pathway inhibitor indicated for treatment of adults with metastatic or locally advanced basal cell carcinoma (BCC) that has recurred after surgery or for patients who are not candidates for surgery or radiation. OBJECTIVE: An efficacy and safety analysis was conducted 12 months after primary analysis. METHODS: This was a multinational, multicenter, nonrandomized, 2-cohort study in patients with measurable and histologically confirmed locally advanced or metastatic BCC taking oral vismodegib (150 mg/d). Primary outcome measure was objective response rate (complete and partial responses) assessed by independent review facility. RESULTS: After 12 months of additional follow-up, median duration of exposure to vismodegib was 12.9 months. Objective response rate increased from 30.3% to 33.3% in patients with metastatic disease, and from 42.9% to 47.6% in patients with the locally advanced form. Median duration of response in patients with locally advanced BCC increased from 7.6 to 9.5 months. No new safety signals emerged with extended treatment duration. LIMITATIONS: Limitations include low prevalence of advanced BCC and challenges of designing a study with heterogenous manifestations. CONCLUSION: The 12-month update of the study confirms the efficacy and safety of vismodegib in management of advanced BCC.
