Year after year, statistics show a steady increase in people of color undergoing aesthetic treatments, with neurotoxins, fillers, laser resurfacing, and body contouring being the most sought-after procedures. When treating this cohort of patients, however, dermatologists need to be sensitized to how a patient's ethnicity affects facial structure, the tissue reaction to treatments, and patient's specific expectations for recommended therapies. A balance between tolerability and efficacy needs to be struck to minimize risk for adverse effects such as postinflammatory hyperpigmentation, which can negatively impact a patient's experience and quality of life.

Fragrances and preservatives are the major sensitizers behind cosmetic-induced ACD, due to their ubiquitous presence in these products, though emulsifiers, ultraviolet filters, and botanical allergens have been implicated as well. While patch testing is the standard for diagnosing ACD, many cosmetic-specific antigens are not currently included within the commercially available kits. Therefore, patch testing for potential cosmetic-induced ACD should be supplemented with additional compounds commonly found in personal use products. Effective treatment of ACD must involve accurate identification and removal of the offending agent.

There is a need for better treatment options for these common conditions that adversely affect physical function and quality of life and that are often underserved by existing options. Lasers have been used to treat genitourinary tissue for over 40 years, and over the past decade, several lasers and radiofrequency devices have been developed and clinically tested for the treatment of GSM, with an accumulating body of evidence demonstrating their safety and efficacy. Fractional lasers, including carbon dioxide, erbium: YAG and hybrid technologies, as well as monopolar radiofrequency devices, work by resurfacing and/or stimulating via heat the vaginal lining resulting in a re-epithelialization, neovascularization, and remodeling of the vaginal tissue from an atrophic postmenopausal state to a thickened, glycogen-rich and well-vascularized state similar to premenopausal vaginal lining. These changes are correlated clinically with improved function on a variety of validated vaginal health scales and urinary incontinence tests. Currently cleared for general application to genitourinary tissue, clinical trials are underway for FDA clearance or approval for specific GSM indications.

Although there is an in-depth understanding of the clinical presentation of these diseases, much less is known regarding the pathophysiology. This has limited the effective treatment options for patients. A more detailed understanding of the pathogenesis of each disease will lead to newer targeted medications with less morbidity. Though there are different pathways involved in these diseases, the Janus Kinase (JAK)-Signal Transducer and Activator of Transcription proteins (STAT) signaling pathway is common to them all. Therefore, this review article endeavors to substantiate the immunopathology and clinical utility of the JAK inhibitors as treatments for different chronic inflammatory diseases of the skin.

As a result of our growing understanding of disease pathogenesis, the therapeutic armamentarium to manage AD is rapidly expanding. Moving beyond broadly immunosuppressive agents, newer therapies for AD offer more targeted immunomodulation in the forms of phosphodiesterase 4 inhibitors, Janus kinase inhibitors, and anticytokine monoclonal antibodies. While such therapies are generally considered safer than traditional immunosuppressive agents that have been used off label for AD for decades, they are not without risk entirely. In some cases, potential side effects may be difficult to manage. This review summarizes current views on AD pathogenesis and discusses these novel and emerging therapies, including a discussion of the mechanisms of action, potential side effects, and limitations of current clinical trials for each drug. While the rapid and prolific expansion of therapies to treat AD is encouraging, additional studies are needed to adequately evaluate the long-term safety, efficacy, and generalizability among different age groups and disease subtypes.

Although many treatments have been tried and tested to date, there is only one Food and Drug Administration-approved treatment option, adalimumab, which is currently indicated for moderateto- severe HS. Our understanding of the management of HS with biologic agents and with nonantibiotic and/ or antimicrobial systemic therapies continues to evolve. In this article, we summarize the existing data on biologics and other small-molecule systemic agents, as well as share our personal experiences with the pharmacological management of HS in the clinical setting. Continued challenges that limit our ability to study and treat this disease effectively include a lack of a universally employed scoring system for disease severity, high variability in clinical presentation, high cost of off-label therapy, and the scarcity of long-term studies on treatment response and medication safety.

PsA is a prevalent and underdiagnosed disease with potential long-term complications and sequelae for patients. Targeted biologics have transformed the landscape of psoriasis and PsA therapy. These medications variably treat clinical manifestations of psoriatic disease: skin psoriasis, peripheral and axial arthritis, enthesitis, and nail disease. With many new medications either on the market or currently being evaluated by the Food and Drug Administration, the purpose of this article is to review PsA for the dermatologist, to identify the current therapies that are available, and to help select which patients may benefit from these medications. Overall, it is important to decide therapy for patients based on the active domains of their disease, their comorbidities, and the safety profiles of these medications, as well as patient preference for route of administration, frequency, and tolerability.

Methotrexate has been the most commonly used systemic agent in children. However, at least 25% of patients are now treated with biologics, especially tumor necrosis factor-α inhibitors, and their use is expanding as their availability, demonstrated safety and efficacy, and practitioner experience are increasing. In the United States, etanercept is Food and Drug Administration approved for ages 6 years and older and ustekinumab for 12 years of age and older. In Europe, adalimumab is also approved for pediatric psoriasis for 4 years of age and older. While biologics have the advantage of less frequent administration, greater and more rapid efficacy than methotrexate, fewer side effects, and a less rigorous need for monitoring, their cost is much higher than that of methotrexate and other systemic medications, concerns about the development of neutralizing antibodies necessitate continuous treatment, and their long-term safety profile remains to be determined.

Moderate to severe psoriasis often requires systemic treatments, including oral systemic therapies and biologics. An addition to the treatment repository for psoriasis is oral small molecules, which include apremilast, tofacitinib, and ponesimod. Of these 3 medications, only apremilast is currently approved for the treatment of psoriasis. Long-term safety data for apremilast suggest that it has a tolerable safety profile and leads to significant improvement in patients with psoriasis; however, there are few head-to-head comparisons with other oral systemic medications. Tofacitinib and ponesimod have demonstrated clinical efficacy in treating psoriasis; however, further studies are required to understand the benefit-risk profile of these medications in psoriasis patients.

At this time, 2 inhibitors of IL-23 p19 have been approved by the United States Food and Drug Administration, guselkumab and tildrakizumab. Two other agents, risankizumab and mirikizumab, have completed phase 3 and phase 2 of development, respectively. Pivotal trials in the development of these agents and clinical use of the approved agents are discussed. Thus far, this class of medications seems to provide a high level of efficacy, along with infrequent dosing and very favorable safety results.
The role of the Th17/interleukin (IL)-23 pathway has been well elucidated in psoriasis. The IL-17 family includes 6 cytokines: IL-17A, IL-17B, IL-17C, IL-17D, IL-17E, and IL-17F.

The IL-17 family includes 6 cytokines: IL-17A, IL-17B, IL-17C, IL-17D, IL-17E, and IL-17F. Two monoclonal antibodies targeting IL-17A (secukinumab, ixekizumab) and one antibody against the IL-17 receptor (brodalumab) have been approved for the treatment of moderate-to-severe plaque psoriasis. Clinical efficacy, safety, and tolerability of each agent is reviewed.

Here, we review new evidence since ustekinumab was licensed for relative efficacy in comparison with other biologic therapies from head-to-head randomized controlled trials and network meta-analyses for the treatment of psoriasis. We also review observational data emerging from psoriasis registries reporting the effectiveness and safety of ustekinumab. Overall, new evidence suggests that ustekinumab has a favorable balance between efficacy/effectiveness, safety, and tolerability and should remain a first-line biologic therapy option for patients with severe psoriasis at present.

The TNF inhibitors (TNFi's) infliximab, adalimumab, and etanercept are efficacious, Food and Drug Administration-approved medications for the treatment of moderate-to-severe plaque psoriasis. Each drug has a unique pharmacological profile that can have therapeutic implications when choosing a particular TNFi for a patient. An understanding of these idiosyncrasies can help guide therapeutic decisions for patients with psoriasis that also have inflammatory bowel disease, hepatitis C, hepatitis B, latent tuberculosis, obesity, cardiovascular disease, and heart failure. It can also help when selecting the right treatment for pregnant patients, children and adolescents, or those with insurance constraints or compliance issues.
