Acne is a common skin condition in adolescent patients but much less common in childhood. Pediatric providers should be familiar with the varying presentations in the pediatric population and recognize when additional physical signs of hyperandrogenism are present. This article details the pathogenesis and presentation of acne in infancy, mid-childhood, and preadolescence. The differential diagnosis is discussed and recommendations for initial workup, referral, and treatment are provided. [Pediatr Ann. 2024;53(4):e115-e120.].

Dissolving Hyaluronic Acid-Based Microneedles to Transdermally Deliver Eugenol Combined with Photothermal Therapy for Acne Vulgaris Treatment.

A microneedle transdermal drug delivery system simultaneously avoids systemic toxicity of oral administration and low efficiency of traditional transdermal administration, which is of great significance for acne vulgaris therapy. Herein, eugenol-loaded hyaluronic acid-based dissolving microneedles (E@P-EO-HA MNs) with antibacterial and anti-inflammatory activities are developed for acne vulgaris therapy via eugenol transdermal delivery integrated with photothermal therapy. E@P-EO-HA MNs are pyramid-shaped with a sharp tip and a hollow cavity structure, which possess sufficient mechanical strength to penetrate the stratum corneum of the skin and achieve transdermal delivery, in addition to excellent in vivo biocompatibility. Significantly, E@P-EO-HA MNs show effective photothermal therapy to destroy sebaceous glands and achieve antibacterial activity against deep-seated Propionibacterium acnes (P. acnes) under near-infrared-light irradiation. Moreover, cavity-loaded eugenol is released from rapidly dissolved microneedle bodies to play a sustained antibacterial and anti-inflammatory therapy on the P. acnes infectious wound. E@P-EO-HA MNs based on a synergistic therapeutic strategy combining photothermal therapy and eugenol transdermal administration can significantly alleviate inflammatory response and ultimately facilitate the repair of acne vulgaris. Overall, E@P-EO-HA MNs are expected to be clinically applied as a functional minimally invasive transdermal delivery strategy for superficial skin diseases therapy in skin tissue engineering.

Effect of CO2 fractional laser combined with recombinant human epidermal growth factor gel on skin barrier.

To evaluate the impact of CO2 fractional laser combined with recombinant human epidermal growth factor (rhEGF) gel on skin barrier in acne scar patients. In a retrospective analysis, we examined 105 acne scar patients admitted between July 2018 and August 2021. Of these, 51 received only CO2 fractional laser (control group), while 54 underwent a combination of CO2 fractional laser and rhEGF gel (observation group). We assessed treatment efficacy, symptom relief, skin barrier parameters, pre- and posttreatment inflammatory factors, adverse reactions, posttreatment quality of life, and patient satisfaction. The observation group exhibited a higher overall response rate, significantly shorter wound healing, scab formation, and scab detachment times. Additionally, this group showed increased stratum corneum water content, decreased pH, and transdermal water loss (TEWL), and reduced hypersensitive C-reactive protein and interleukin-6 expression posttreatment. Quality of life scores were higher, with fewer adverse reactions and greater treatment satisfaction. Combining CO2 fractional laser with rhEGF gel markedly improves acne scar treatment efficacy, enhances skin barrier function, reduces inflammation, and elevates quality of life. Its safety profile supports its broader clinical adoption.

Prevalence of acne and its impact on quality of life and practices regarding self-treatment among medical students.

Acne vulgaris is one of the most common skin diseases worldwide and causes great distress to patients. In addition, most acne patients suffer from low self-esteem and social withdrawal. This study aimed to assess the prevalence of acne and its impact on quality of life among medical students. It also evaluates the patterns of self-treatment use. The study population consisted of all medical students from An-Najah National University (ANU) and the hospital. The questionnaire consists of three parts, and the first part consists of questions regarding demographic information. The second part consisted of questions to measure the severity of acne using the acne severity scale as well as the Cardiff Disability Index, which assesses the quality of life concerning acne in medical students. Finally, the third part consisted of questions exploring and assessing acne self-treatment. The mean age of our study sample was 21.3 ± 1.9 years, with a female predominance of 72.3%. The prevalence of acne among medical students was 80.9%, and 36.6% practiced self-medication. Acne was strongly associated with female sex (p < 0.001) and skin type (p = 0.024). Regarding diet, dairy consumption (p = 0.007), sweets (p < 0.001), chocolate (p < 0.001), and oily food (p = 0.006) were all significantly associated with acne. Skin type was strongly associated with the severity of acne (p < 0.001) and the Cardiff acne disability index (p = 0.016). Gender (p = 0.039) was also associated with Cardiff acne disability. A significant correlation was found between the severity of acne and impaired quality of life. The most commonly used topical agent for self-treatment remedies was antibiotics (70.3%). The most commonly used oral agent was isotretinoin (9.4%). A total of 22.7% of the students used herbal products, while 47.7% used home remedies. Acne is prevalent among medical students, with a high percentage of students having different degrees of impairment in their daily lives. As a result, self-medication among acne sufferers is highly common. Awareness of the appropriate use of self-medication should increase among medical students.

A 595 nm pulsed dye laser as an adjuvant intervention for post-comedone extraction erythema and comedone reduction: A randomized, split-face controlled trial.

BACKGROUND: Comedone extraction provides greater satisfaction for acne treatment than conventional treatment alone; however, post-comedone extraction erythema (PCEE) remains a concern for patients. OBJECTIVES: To evaluate the efficacy of pulsed-dye laser (PDL) in PCEE and comedone reduction. METHODS: Mild-to-moderate acne patients were randomly allocated in split-face fashion. Three comedones were extracted on each facial side. On the PDL-treated side, 595-nm PDL was delivered to the entire side with an additional shot on three comedone-extracted sites. Erythema index (EI) and total acne lesion counts (TALC) were evaluated at baseline, week 2 and 4. The comprehensive acne severity scale (CASS) was assessed by three blinded independent pediatric dermatologists. Participant satisfaction surveys were completed at the end of the study. RESULTS: Thirty-five participants (age 12.9-24.2 years) showed no differences in the EI and TALC at baseline on both sides. At weeks 2 and 4, the EI on the PDL-treated side was significantly lower (p < 0.001) with a greater EI reduction (p < 0.001) when compared to the control side regardless of gender and menstruation. There was significantly lower TALC on the PDL-treated side at week 2 (p < 0.001) and week 4 (p = 0.02). No complications were noted with high participant satisfaction reported (median 8; IQR 7-9). PDL remained significantly associated with EI improvements after controlling for gender, menstruation cycle, and examination stress. CONCLUSION: PDL can be an adjunctive intervention for the treatment of PCEE and comedone reduction due to its effectiveness and high participant satisfaction.

Long-term efficacy and safety of nonablative monopolar radiofrequency in the treatment of moderate to severe acne vulgaris.

BACKGROUND: Acne vulgaris (AV) is a prevalent skin condition known for its potential to cause scarring and psychological distress, often leading to diminished self-esteem. While topical and oral treatments are commonly prescribed, some patients experience treatment failure, adverse effects, or contraindications to conventional therapies. In response to these challenges, laser and energy-based device therapies have emerged as promising alternatives for individuals who fall into these categories, showing considerable potential in the treatment of AV. OBJECTIVE: This study aimed to evaluate the long-term efficacy and safety of a nonablative monopolar radiofrequency (NMRF) in treatment of moderate to severe AV. METHODS: Twenty-four patients with moderate to severe AV underwent a series of two NMRF treatment sessions, spaced 4 weeks apart. To evaluate treatment outcomes, live in-person lesion counts and measurements of pore size and volume, and sebum production were quantified using Antera® 3D imaging system, and Sebumeter®, respectively. Patients' self-assessment data regarding degree of improvement and facial oiliness were gathered. Dermatology life quality index (DLQI) questionnaire was utilized to assess the impact of AV on their quality of life. All objective and subjective evaluations were conducted at the baseline, 1 month after the first treatment, and during follow-up visits 1, 3, and 6 months after the last treatment sessions. Adverse effects were also recorded during each visit. RESULTS: Twenty out of the 24 subjects completed the study protocol. The mean inflammatory lesion counts significantly reduced by 42.86% and 45.71% from the baseline at 3 (p = 0.027) and 6 months (p = 0.032) after the second treatment. Sebum excretion likewise significantly decreased from baseline by 11.62% (p = 0.012), 13.37% (p < 0.001), and 21.51% (p = 0.004), 1 month after the first treatment, 1 and 6 months after the second treatment, respectively. The pore volume continued to decrease by 35% (p = 0.003) and 41.5% (p < 0.001) at 1 and 6 months following the final treatment, respectively. The DLQI significantly decreased from 10.00 (interquartile range [IQR]: 6.50-15.00) to 2.00 (IQR: 1.00-4.75), corresponding to 80% improvement of the index, 1 month after the last treatment and was sustained up to the last follow-up visit. Patients' self-assessments on degree of improvement and facial oiliness also significantly improved following NMRF treatments. The treatments were well-tolerated without significant adverse effects. CONCLUSION: NMRF appears to be an effective and safe treatment for inflammatory AV, with therapeutic outcomes persisting up to 6 months after two treatment sessions.

An innovative microcoring technology: A novel approach to acne scar treatment.

BACKGROUND: Acne scars present a complex challenge in dermatology and cosmetics, despite advancements in technological interventions such as fractional lasers, microneedling, and surgical procedures. Effective treatment remains elusive for many individuals. OBJECTIVE: This study aims to evaluate the efficacy of rotational fractional resection using 1 mm diameter rotating scalpels as a primary treatment for icepick and boxcar scars on the cheeks and glabella region. METHODS: Three patients with acne scars underwent a single treatment session of rotational fractional resection. Evaluation occurred at the 2-month post-treatment mark to assess improvements in scar appearance and potential skin-related side effects. RESULTS: Following the treatment, significant improvements were observed in the targeted acne scars. Notable enhancements were noted without major skin-related adverse effects, except for minor suture marks. CONCLUSION: The outcomes of this study underscore the potential of rotational fractional resection as an innovative and effective approach in treating acne scars. This single-session cosmetic procedure shows promise in yielding lasting and quantifiable results, offering a hopeful solution for individuals seeking comprehensive acne scar treatment.

A simple drug-delivery microneedling technique modality successfully improves linear atrophic scars.

BACKGROUND: Atrophic scars are white, dermal depressions, caused by the destruction of collagen fibers and decrease in epidermal cells, following inflammation after different types of trauma. They lead to significant physical, aesthetic and psychological barriers and their treatment remain a therapeutic challenge for dermatologists. Microneedling has been shown to improve scars by stimulating angiogenesis and neocolagenesis and the combination of anti-fibrotic drugs could potentialize the results. METHODS: We present 8 cases of patients with linear scars, successfully treated with two sessions of a new Microneedling technique, using a tattoo machine, associated with drug delivery of 5-FU. RESULTS: A marked improvement in scar pigmentation and texture were noted by patients and doctors, 6 months following the sessions of MMP and drug delivery with 5-FU, in different body sites. We also showed that the assessment scores of at least one of the professionals with those of the patient had significant correlations with each other, which shows consistency between the qualitative assessment instruments. We also showed that the cause of the injury can influence joint assessment scores (physicians plus patient) or those exclusive to professionals trained for the assessments, generating evidence that the cause of the injury can influence the treatment outcome itself. CONCLUSIONS: We present an inexpensive and promising approach that can be easily done as an in-office procedure. Larger, multicenter studies are needed to validate this technique among the first line therapies for acne scar treatment.

Acne microbiome: From phyla to phylotypes.

Acne vulgaris is a chronic inflammatory skin disease with a complex pathogenesis. Traditionally, the primary pathophysiologic factors in acne have been thought to be: (1) altered sebum production, (2) inflammation, (3) excess keratinization and (4) colonization with the commensal Cutibacterium acnes. However, the role of C. acnes has been unclear, since virtually all adults have C. acnes on their skin yet not all develop acne. In recent years, understanding of the role of C. acnes has expanded. It is still acknowledged to have an important place in acne pathogenesis, but evidence suggests that an imbalance of individual C. acnes phylotypes and an alteration of the skin microbiome trigger acne. In addition, it is now believed that Staphylococcus epidermidis is also an actor in acne development. Together, C. acnes and S. epidermidis maintain and regulate homeostasis of the skin microbiota. Antibiotics, which have long been a staple of acne therapy, induce cutaneous dysbiosis. This finding, together with the long-standing public health edict to spare antibiotic use when possible, highlights the need for a change in acne management strategies. One fertile direction of study for new approaches involves dermocosmetic products that can support epidermal barrier function and have a positive effect on the skin microbiome.

Fractional ablative CO2 laser and oral isotretinoin-A prospective randomized controlled split-face trial comparing concurrent versus delayed laser treatment for acne scars.

BACKGROUND: Therapeutic dogma has been to treat acne scars with ablative fractional laser no less than 6 months after isotretinoin (ITN) cessation. OBJECTIVE: To evaluate the safety and efficacy of fractional ablative CO2 laser (FACL) in patients treated concurrently with ITN. METHODS: We conducted a prospective split-face randomized control trial in patients treated with FACL concurrently with ITN versus patients treated with FACL 6 months post-ITN treatment. Patients received 3 monthly sessions of FACL with concurrent ITN treatment on half of the face; the other side of the face received the same FACL treatment regimen 6 months post-ITN cessation. Patients were followed for adverse effects up to 6 months post-FACL treatment. Final cosmesis was scored using the Quantitative Global Acne Scarring Grading System (GASGS) by three independent dermatologists. RESULTS: The GASGS of the concurrent ITN-FACL treated side of the face was significantly lower than the side treated with delayed laser therapy (4.7 ± 2.5 vs. 7.7 ± 2.9, respectively, p < 0.001). LIMITATIONS: The laser's settings were standardized, and not adjusted per patient skin type. CONCLUSION: Per our prospective trial, concurrent treatment of FACL -ITN is superior to delayed FACL treatment 6 months post-ITN cessation. Fractional ablative laser treatment is effective in improving acne scars, which persist despite isotretinoin therapy.

Fractional CO 2 Laser Combined With Autologous Nanofat Injection Versus Fractional CO 2 Laser Combined With Platelet-Rich Plasma in the Treatment of Atrophic Acne Scars: A Split-Face Comparative Study With Optical Skin Imaging.

BACKGROUND: Atrophic acne scarring is a common problem. If left untreated, its implications can impair the quality of life. Various treatments, with differing degrees of success, are used to alleviate atrophic scars. OBJECTIVE: To assess the efficacy of nanofat versus platelet-rich plasma (PRP) as an adjuvant therapy to fractional CO 2 laser (FCL) for atrophic acne scars. METHODS: This study included 35 patients with atrophic acne scars who received 3 sessions of FCL at 1-month intervals on both sides of the face, followed by intradermal PRP injection on the left side. A single session of nanofat was injected into the right side of the face 2 weeks before the laser sessions. The evaluation was conducted 3 months after the final treatment session. RESULTS: After treatment, the right side of the face showed a significant reduction in Goodman scores and the indentation index of the Antera camera. The left side showed a significant difference in Goodman scores, yet the Antera camera showed a nonsignificant improvement. Nonetheless, the difference between the 2 sides was statistically insignificant. CONCLUSION: Atrophic acne scars improved with both modalities. As a result, cotreatment with these techniques may synergistically affect atrophic acne scars in efficacy and safety.

The Acne Education Project: An educational initiative to improve acne health literacy and promote help-seeking behavior in young adolescents.

BACKGROUND: Acne vulgaris is an inflammatory skin condition that is associated with poor acne health literacy. Diminished acne health literacy leads to delays in the access of health care, resulting in mismanagement, disfigurement, and psychosocial morbidity. This study evaluates the potential role of early acne education in young adolescent populations to improve acne health literacy and facilitate help-seeking behavior. METHODS: The Acne Education Project is a Canadian medical student-led initiative founded to create evidence-based resources to increase acne health literacy. A 45-min interactive Zoom presentation on acne was created and delivered to 2292 students ages 9-13 in British Columbia, Canada. A quality improvement survey was administered pre-intervention, immediate post-intervention, and 1-month post-intervention to evaluate baseline acne knowledge and knowledge retention to guide presentation and resource development. RESULTS: Responses from 676 unique individuals were collected. Analysis using linear mixed-effects models demonstrated that respondents were significantly more confident in their general knowledge of acne, strategies to prevent acne, identification of psychosocial sequelae of acne, and more willing to seek help immediately post-intervention (p < .001). Differences in scores were not fully preserved in magnitude at the 1-month post-intervention assessment. However, students still scored significantly higher in all categories compared to the pre-intervention baseline (p < .001). CONCLUSION: Our findings suggest that early acne education can improve acne health literacy and promote help-seeking behavior. Given the potential long-term implications, further research is needed to explore the long-term impact of early acne education and the benefit of integrating acne education into the public education curriculum in Canada.
