Review
Acne is one of the most common disorders treated by dermatologists and other health care providers. While it most often affects adolescents, it is not uncommon in adults and can also be seen in children. This evidence-based guideline addresses important clinical questions that arise in its management. Issues from grading of acne to the topical and systemic management of the disease are reviewed. Suggestions on use are provided based on available evidence.

Acne vulgaris is the most prevalent chronic skin disease in the United States, affecting nearly 50 million people per year, mostly adolescents and young adults. Potential sequelae of acne, such as scarring, dyspigmentation, and low self-esteem, may result in significant morbidity. Typical acne lesions involve the pilosebaceous follicles and the interrelated processes of sebum production, Cutibacterium acnes (previously called Propionibacterium acnes) colonization, and inflammation. Acne may be classified as mild, moderate, or severe based on the number and type of skin lesions. Multiple treatment agents and formulations are available, with each agent targeting a specific area within acne pathogenesis. Treatment selection is based on disease severity, patient preference, and tolerability. Topical retinoids are indicated for acne of any severity and for maintenance therapy. Systemic and topical antibiotics should be used only in combination with benzoyl peroxide and retinoids and for a maximum of 12 weeks. Isotretinoin is used for severe, recalcitrant acne. Because of the risk of teratogenicity, patients, pharmacists, and prescribers must register with the U.S. Food and Drug Administration-mandated risk management program, iPledge, before implementing isotretinoin therapy. There is limited evidence for physical modalities (e.g., laser therapy, light therapy, chemical peels) and complementary therapies (e.g., purified bee venom, low-glycemic-load diet, tea tree oil); therefore, further study is required.

Review
Skin aging is influenced by intrinsic and extrinsic factors and involves multiple pathogenic mechanisms. The most widely used treatments are topical products and minimally invasive procedures. Evidence on the benefits of systemic therapy is limited for several reasons: Reliance on mostly small and predominantly female samples, short study durations, methodologic heterogeneity, and a lack of consensus on which outcome measures are clinically relevant. Furthermore, systemic drugs and oral supplements are not without adverse effects. Oral hydrolyzed collagen and oral hyaluronic acid are well tolerated, and numerous clinical trials show they can mitigate some signs of skin aging. Low-dose oral isotretinoin is another option, but it has a higher risk of adverse effects. Evidence is lacking on the effects of the many dietary supplements on offer, such as vitamins, flavonoids, plant extracts, and trace elements. The future of skin aging management would appear to lie in the use of senolytic and senomorphic agents targeting senescent cells in the skin.

Review
In 1982, the Food and Drug Administration (FDA) of the United States of America approved isotretinoin (13-cis-retinoic acid), a retinoid derivative of vitamin A, to treat severe recalcitrant acne vulgaris. Apart from its prescribed use for severe acne, evidence suggests that isotretinoin is commonly used off-label to treat mild-to-moderate acne, inflammatory skin conditions, genodermatoses, skin cancer, and other skin disorders. This is due to its anti-inflammatory, immunomodulatory, and antineoplastic properties. Some "off-label" use is successful, while others are ineffective. Therefore, this information is essential to clinicians for deciding on the appropriate use of isotretinoin. In this article, we aim to review the most updated evidence-based data about the use of oral isotretinoin in dermatology.

Review
Acne fulminans (AF) is a rare and severe form of inflammatory acne presenting clinically with an abrupt outburst of painful, hemorrhagic pustules and ulceration, that may or may not be associated with systemic symptoms, such as fever, polyarthritis, and laboratory abnormalities. It typically affects male teenagers with a pre-existing acne. Although the pathogenetic mechanism has not been established yet, a role of genetic, abnormal immunologic response, drugs intake, hormonal imbalance and viral infection, as causal factors, has been identified. AF may occur as a single disease or may be associated with other disorders. Traditionally, AF has been classified, on the basis of the presence of systemic involvement, in "acne fulminans" and acne fulminans "sine fulminans," when no systemic involvement is present. Recently, four clinical variants have been proposed: acne fulminans with systemic symptoms (AF-SS), acne fulminans without systemic symptoms (AF-WOSS), isotretinoin-induced acne fulminans with systemic symptoms (IIAF-SS), isotretinoin-induced acne fulminans without systemic symptoms (IIAF-WOSS). The diagnosis of AF is usually based on clinical history and physical examination. No specific laboratory abnormalities are generally found. In selected cases, biopsy and/or radiologic imaging are helpful for a correct diagnosis. The treatment significantly differs from severe acne according to severity of clinical presentation and possible systemic involvement. Currently, systemic corticosteroids (prednisolone) and retinoids (isotretinoin) represent the first choice of treatment. Dapsone, cyclosporine A, methotrexate, azathioprine, levamisole, and biological agents such as anakinra, infliximab, adalimumab may be considered as alternative therapies in selected cases. Adjunctive topical and physical therapies may also be considered.

Meta-Analysis Review
BACKGROUND
Various treatments for acne vulgaris exist, but little is known about their comparative effectiveness in relation to acne severity.
OBJECTIVES
To identify best treatments for mild-to-moderate and moderate-to-severe acne, as determined by clinician-assessed morphological features.
METHODS
We undertook a systematic review and network meta-analysis of randomized controlled trials (RCTs) assessing topical pharmacological, oral pharmacological, physical and combined treatments for mild-to-moderate and moderate-to-severe acne, published up to May 2020. Outcomes included percentage change in total lesion count from baseline, treatment discontinuation for any reason, and discontinuation owing to side-effects. Risk of bias was assessed using the Cochrane risk-of-bias tool and bias adjustment models. Effects for treatments with ≥ 50 observations each compared with placebo are reported below.
RESULTS
We included 179 RCTs with approximately 35 000 observations across 49 treatment classes. For mild-to-moderate acne, the most effective options for each treatment type were as follows: topical pharmacological - combined retinoid with benzoyl peroxide (BPO) [mean difference 26·16%, 95% credible interval (CrI) 16·75-35·36%]; physical - chemical peels, e.g. salicylic or mandelic acid (39·70%, 95% CrI 12·54-66·78%) and photochemical therapy (combined blue/red light) (35·36%, 95% CrI 17·75-53·08%). Oral pharmacological treatments (e.g. antibiotics, hormonal contraceptives) did not appear to be effective after bias adjustment. BPO and topical retinoids were less well tolerated than placebo. For moderate-to-severe acne, the most effective options for each treatment type were as follows: topical pharmacological - combined retinoid with lincosamide (clindamycin) (44·43%, 95% CrI 29·20-60·02%); oral pharmacological - isotretinoin of total cumulative dose ≥ 120 mg kg per single course (58·09%, 95% CrI 36·99-79·29%); physical - photodynamic therapy (light therapy enhanced by a photosensitizing chemical) (40·45%, 95% CrI 26·17-54·11%); combined - BPO with topical retinoid and oral tetracycline (43·53%, 95% CrI 29·49-57·70%). Topical retinoids and oral tetracyclines were less well tolerated than placebo. The quality of included RCTs was moderate to very low, with evidence of inconsistency between direct and indirect evidence. Uncertainty in findings was high, in particular for chemical peels, photochemical therapy and photodynamic therapy. However, conclusions were robust to potential bias in the evidence.
CONCLUSIONS
Topical pharmacological treatment combinations, chemical peels and photochemical therapy were most effective for mild-to-moderate acne. Topical pharmacological treatment combinations, oral antibiotics combined with topical pharmacological treatments, oral isotretinoin and photodynamic therapy were most effective for moderate-to-severe acne. Further research is warranted for chemical peels, photochemical therapy and photodynamic therapy for which evidence was more limited. What is already known about this topic? Acne vulgaris is the eighth most common disease globally. Several topical, oral, physical and combined treatments for acne vulgaris exist. Network meta-analysis (NMA) synthesizes direct and indirect evidence and allows simultaneous inference for all treatments forming an evidence network. Previous NMAs have assessed a limited range of treatments for acne vulgaris and have not evaluated effectiveness of treatments for moderate-to-severe acne. What does this study add? For mild-to-moderate acne, topical treatment combinations, chemical peels, and photochemical therapy (combined blue/red light; blue light) are most effective. For moderate-to-severe acne, topical treatment combinations, oral antibiotics combined with topical treatments, oral isotretinoin and photodynamic therapy (light therapy enhanced by a photosensitizing chemical) are most effective. Based on these findings, along with further clinical and cost-effectiveness considerations, National Institute for Health and Care Excellence (NICE) guidance recommends, as first-line treatments, fixed topical treatment combinations for mild-to-moderate acne and fixed topical treatment combinations, or oral tetracyclines combined with topical treatments, for moderate-to-severe acne.

Review
This review on acne transcriptomics allows for deeper insights into the pathogenesis of acne and isotretinoin's mode of action. Puberty-induced insulin-like growth factor 1 (IGF-1), insulin and androgen signaling activate the kinase AKT and mechanistic target of rapamycin complex 1 (mTORC1). A Western diet (hyperglycemic carbohydrates and milk/dairy products) also co-stimulates AKT/mTORC1 signaling. The AKT-mediated phosphorylation of nuclear FoxO1 and FoxO3 results in their extrusion into the cytoplasm, a critical switch which enhances the transactivation of lipogenic and proinflammatory transcription factors, including androgen receptor (AR), sterol regulatory element-binding transcription factor 1 (SREBF1), peroxisome proliferator-activated receptor γ (PPARγ) and signal transducer and activator of transcription 3 (STAT3), but reduces the FoxO1-dependent expression of GATA binding protein 6 (GATA6), the key transcription factor for infundibular keratinocyte homeostasis. The AKT-mediated phosphorylation of the p53-binding protein MDM2 promotes the degradation of p53. In contrast, isotretinoin enhances the expression of p53, FoxO1 and FoxO3 in the sebaceous glands of acne patients. The overexpression of these proapoptotic transcription factors explains isotretinoin's desirable sebum-suppressive effect via the induction of sebocyte apoptosis and the depletion of BLIMP1(+) sebocyte progenitor cells; it also explains its adverse effects, including teratogenicity (neural crest cell apoptosis), a reduced ovarian reserve (granulosa cell apoptosis), the risk of depression (the apoptosis of hypothalamic neurons), VLDL hyperlipidemia, intracranial hypertension and dry skin.

Meta-Analysis Review
Isotretinoin (ISO) is an oral prescription-only retinoid, well known for its acne-treating effect. However, it affects a substantial number of human cell types, causing a broad spectrum of adverse effects. The purpose of this study is to establish the isotretinoin therapy adverse events among human clinical trials and their prevalence. Two authors (J.K., J.L.) systematically performed the literature review and assessment from December 2021-February 2022. Three databases (PubMed, ClinicalTrials, and Cochrane Library) were searched using the following terms: "isotretinoin acne vulgaris" for published studies in English from 1980-2021. Finally, 25 randomized controlled clinical trials (RCTs) and five open-label clinical trials provided 3274 acne vulgaris suffering patients. Isotretinoin therapy affects almost all of the systems in the human body, causing numerous adverse events. However, they mainly concern mild mucocutaneous conditions (severe cases are rare) and represent individual responses to a drug. In addition, all adverse events are reversible and can be avoided by specific preparations.

Review
BACKGROUND
Exacerbation of rosacea may occur during pregnancy and there are multiple associated cases of rosacea fulminans (RF). Treatment during pregnancy poses a significant challenge as many rosacea treatments are contraindicated or have limited evidence regarding potential adverse fetal effects.
OBJECTIVE
Review the pregnancy categories of various treatments and develop algorithms for treating pregnant patients with rosacea and RF.
METHODS
Rosacea treatments showing efficacy in randomized controlled trials were searched through DailyMed to review pregnancy labelling. Searching the PubMed/MEDLINE database for English articles using keywords "rosacea fulminans AND pregnancy" without publishing-time restrictions yielded 8 articles. We summarized treatments used in cases of RF during pregnancy.
RESULTS
Topical ivermectin was more effective than metronidazole, but has a more concerning pregnancy category. Three pregnant women with RF were treated successfully with topical metronidazole in combination with other therapies. Azithromycin is the only oral rosacea therapy that is considered safe for pregnant patients and it has been used to treat RF.
CONCLUSIONS
This review highlights the challenging aspects of treating pregnant patients with rosacea, as there is limited pregnancy-related treatment efficacy and safety data. The pregnancy categories of therapeutic options are summarized. Further studies are needed to learn which therapies are effective and safe for use during pregnancy.

Review
Acne should not be perceived as a self-limiting affliction of adolescence. Due to the growing problem of antimicrobial-resistant bacteria, restrictive use of peroral and topical antibiotics is recommended. There are a number of effective agents for topical treatment of mild to moderate acne. In cases of severe, therapy-resistant acne, treatment with peroral isotretinoin is recommended.
