Review
Metformin is a widely used drug for treatment of diabetes mellitus, due to its safety and efficacy. In addition to its role as an antidiabetic drug, numerous beneficial effects of metformin have enabled its use in various diseases. Considering the anti-androgenic, anti-angiogenic, anti-fibrotic and antioxidant properties of metformin, it may have the potential to improve chronic inflammatory skin diseases. However, further evidence is needed to confirm the efficacy of metformin in dermatological conditions, This review focuses on exploring the therapeutic targets of metformin in acne vulgaris, hidradenitis suppurativa and rosacea, by studying their pathogeneses.

Review
Acne is a common cause for post-inflammatory hyperpigmentation (PIH), particularly in patients with skin of color (SOC), and PIH is often more distressing to patients than the acne itself. Topical retinoids are approved for the treatment of acne and for pigmentation disorders such as melasma or mottled hyperpigmentation associated with photodamage; moreover, they have been shown to reduce hyperpigmentation in patients with SOC. Therefore, treatment with topical retinoids should be started as early as possible unless contraindicated. Use of novel formulations or application of commonly recommended moisturizers may help reduce irritation. Combining retinoids with other topical agents and procedures such as superficial chemical peels can help to improve hyperpigmentation. Primary acne lesions are likely to improve weeks before PIH resolves and helping patients manage their expectations may reduce frustration. Providing clinicians and researchers with more education about the presentation and management of dermatologic conditions in patients with SOC is also recommended.

Review
The role of exogenous progestin in the development of acne is unclear. Progestins are known for their androgenic potential, but newer generations of progestins have low or anti-androgenic activity. This review will evaluate the association between progestins found in hormonal long-acting reversible contraceptives (intrauterine devices and subdermal implants) and acne, as well as the role of oral contraceptives in acne management. Our review demonstrates that the cause and effect relationship between progestins and acne is difficult to establish and future studies that seek to understand how progestins modulate acne are necessary.

BACKGROUND
Despite a growing body of evidence that acne impacts mental disorders, the actual causality has not been established for the possible presence of recall bias and confounders in observational studies.
METHODS
We performed a two-sample Mendelian randomization (MR) analysis to evaluate the effect of acne on the risk of six common mental disorders, i.e., depression, anxiety, schizophrenia, obsessive-compulsive disorder (OCD), bipolar disorder, and post-traumatic stress disorder (PTSD). We acquired genetic instruments for assessing acne from the largest genome-wide association study (GWAS) of acne ( = 615,396) and collected summary statistics from the largest available GWAS for depression ( = 500,199), anxiety ( = 17,310), schizophrenia ( = 130,644), OCD ( = 9,725), bipolar disorder ( = 413,466), and PTSD ( = 174,659). Next, we performed the two-sample MR analysis using four methods: inverse-variance weighted method, MR-Egger, weighted median, and MR pleiotropy residual sum and outliers. Sensitivity analysis was also performed for heterogeneity and pleiotropy tests.
RESULTS
There was no evidence of a causal impact of acne on the risk of depression [odds ratio (OR): 1.002, = 0.874], anxiety (OR: 0.961, = 0.49), OCD (OR: 0.979, = 0.741), bipolar disorder (OR: 0.972, = 0.261), and PTSD (OR: 1.054, = 0.069). Moreover, a mild protective effect of acne against schizophrenia was observed (OR: 0.944; = 0.033).
CONCLUSION
The increased prevalence of mental disorders observed in patients with acne in clinical practice was caused by modifiable factors, and was not a direct outcome of acne. Therefore, strategies targeting the elimination of potential factors and minimization of the occurrence of adverse mental events in acne should be implemented.

BACKGROUND
Acne scar is a persistent complication of acne vulgaris. However, the prevalence and risk factors are still unclear. This study aimed to assess the global prevalence and risk factors of acne scars in patients with acne.
MATERIALS AND METHODS
A systematic search of published studies in three databases was performed and the meta-analyses were conducted.
RESULTS
Finally, we included 37 studies involving 24 649 acne patients. And, the pooled prevalence of acne scars in these patients was 47% (95% confidence interval [CI]: 38-56%). Besides, the differences in prevalence were observed based on the subgroup analysis for age, gender, acne severity, source of patients, and so on. Subsequently, we quantified the relationship of three risk factors with acne scars: male gender (odds ratio [OR]: 1.58, 95% CI: 1.19-2.09), positive family history of acne (OR: 2.73, 95% CI: 1.26-5.91), and acne severity (OR for moderate acne: 2.34, 95% CI: 1.54-3.57; OR for severe acne: 5.51, 95% CI: 2.45-12.41).
CONCLUSION
Herein, we found that 47% of acne patients suffered from acne scars and identified three risk factors: male gender, positive family history of acne, and acne severity. In order to reduce acne scarring, attention and effective therapy early in the course of acne is important.

To date, treatment of atrophic acne scars remains a therapeutic challenge for dermatologists, yet there is no standard option on the most effective treatment. Microneedling (MN) is a minimally invasive technology that involves repetitive skin puncture using sterile microneedles to disrupt dermal collagen that connects the scar tissue. Recent studies have demonstrated the potency of MN, such as dermaroller and fractionated microneedle radiofrequency, in the treatment of atrophic scars. The objective of this review is to evaluate systematically the current literature on MN for atrophic acne scars. A systematic search of literature was performed from PubMed, Medline, Cochrane Central, and Google Scholar databases for articles published during the last 20 years. Only randomised controlled trials (RCTs) with full-text version of the manuscript available were included in our study. Nine RCTs were included in this review. All treatment modalities demonstrated consistent results that MN was efficacious in treating atrophic acne scars as a monotherapy or in combination with other treatments. Moreover, no serious adverse effects were reported in all studies after MN treatment. MN is a well-tolerated and effective therapeutic modality in treating atrophic acne scars. Further research is required to validate the efficacy of MN with a larger sample size and lengthy follow-up.

Comparative Study Randomized Controlled Trial
Prevention and Reduction of Atrophic Acne Scars with Adapalene 0.3%/Benzoyl Peroxide 2.5% Gel in Subjects with Moderate or Severe Facial Acne: Results of a 6-Month Randomized, Vehicle-Controlled Trial Using Intra-Individual Comparison.
BACKGROUND
Very few clinical trials have investigated the effect of topical acne treatment on scarring.
OBJECTIVES
Our objective was to evaluate the efficacy of adapalene 0.3%/benzoyl peroxide 2.5% gel (A0.3/BPO2.5) in atrophic acne scar formation in patients with acne.
METHODS
In this multicenter, randomized, investigator-blinded, vehicle-controlled study, subjects with moderate or severe facial acne (Investigator's Global Assessment [IGA] score 3 or 4; ≥ 25 inflammatory lesions; ten or more atrophic acne scars) applied A0.3/BPO2.5 or vehicle daily per half face for 24 weeks. Subjects with acne requiring systemic treatment were excluded. Assessments included investigator atrophic acne scar count, Scar Global Assessment (SGA), acne lesion count, IGA, skin roughness and skin texture, subject self-assessment of clinical acne-related scars and satisfaction questionnaire, tolerability, and safety.
RESULTS
Included subjects (n = 67) had mainly moderate acne (92.5% IGA 3); mean scores at baseline were approximately 40 acne lesions and 12 scars per half face. By week 24, the change from baseline in total scar count was - 15.5% for A0.3/BPO2.5 versus + 14.4% for vehicle (approximately 30% difference), with a mean of 9.5 scars versus 13.3 per half face, respectively (p < 0.0001). For SGA at week 24, a total of 32.9% with A0.3/BPO2.5 versus 16.4% with vehicle (p < 0.01) were clear/almost clear. Inflammatory acne lesions decreased by 86.7% for A0.3/BPO2.5 versus 57.9% for vehicle (p < 0.0001), and 64.2 versus 19.4% of subjects, respectively, were IGA clear/almost clear (p < 0.0001) at week 24. Treatment-related AEs were reported by 20.9% for A0.3/BPO2.5 versus 9% for vehicle side, most commonly skin irritation (14.9 vs. 6%, respectively).
CONCLUSIONS
Topical A0.3/BPO2.5 prevented and reduced atrophic scar formation. Scar count increased with vehicle (+ 14.4%) but decreased with A0.3/BPO2.5 (- 15.5%) over 24 weeks.

In individuals with acne vulgaris, alterations occur in serum metabolite composition, yet the exact causal link between these metabolites and acne development remains elusive. Using genome-wide association datasets, we performed bidirectional Mendelian randomization (MR) to investigate the potential causal relationship between 309 serum metabolites and acne vulgaris. We performed sensitivity analysis to evaluate the presence of heterogeneity and pleiotropy. Forward MR analysis found 14 serum metabolites significantly associated with acne vulgaris, and reverse MR analysis found no significant association between acne vulgaris and these serum metabolites. Through validation using data from the FinnGen database of acne vulgaris studies, we found a conclusive and significant correlation between stearoylcarnitine and acne vulgaris. This provides new evidence in the search for new targets for the treatment of acne vulgaris.

Review
Acne fulminans is a severe and rare form of inflammatory acne. Lesion severity and subsequent scarring has a negative impact on the patient's quality of life. We conducted a narrative review of the literature on acne fulminans based on a search for relevant English- and Spanish-language articles published in Medline. We included case reports and case series. The main aim was to describe the clinical and demographic characteristics of patients with acne fulminans. A secondary aim was to determine whether quality of life was affected by the site or extent of lesions. We reviewed 91 articles describing 212 cases of acne fulminans. The mean age of the patients (91.94% male) was 16.6 years. A personal and family history of acne vulgaris was reported for 97.63% and 54.90% of patients, respectively. A trigger was identified in 44.79% of cases. The main cause was pharmacologic (96.63%) and the main drug isotretinoin (65.28%). The sites most often affected were the face (89.31%), the posterior trunk (77.86%), and the anterior trunk (74.81%). The predominant disease subtype was acne fulminans with systemic symptoms (59.12%), which were mostly general (97.06%). Systemic corticosteroids were the most widely used treatment (81.03%). The impact of the disease on quality of life was reported for 2 patients. In conclusion, acne fulminans mainly affects the face and trunk of male adolescents with a history of acne vulgaris. The main subtype was acne fulminans with systemic symptoms, and most patients were treated with systemic corticosteroids. The effect of acne fulminans on quality of life is underreported.
