Medical and procedural treatment of androgenetic alopecia - Where are we?

Novel medical and procedural options for androgenetic alopecia have arrived. Low-dose oral minoxidil has made its clinical debut, while data on spironolactone, finasteride, and nutritional supplements have advanced. Minimally invasive technological advancements include photobiomodulation and platelet-rich plasma. Within hair transplantation, follicular unit extraction and robotics are now at the clinicians' fingertips.

Real-World, Open-Label Study of the Efficacy and Safety of a Novel Serum in Androgenetic Alopecia.

Pattern-type hair loss is a highly prevalent condition affecting the majority of men and women at some point in their lifetime. Although genetics and androgens are instrumental in the pathogenesis of this type of hair loss, it is increasingly recognized that inflammation, stress, and environmental factors play a central role. The few and widely used monotherapies approved by the US Food and Drug Administration, such as minoxidil or finasteride, are not efficacious in all people and cause adverse events that prevent patient compliance. Therefore, new treatments that are easy to use and that holistically address the multi-factorial pathophysiology of pattern-type hair loss are needed. Clinical studies have already demonstrated the safety and efficacy of a plethora of bioactive natural products, such as epigallocatechin gallate (EGCG), Vitis vinifera seed extract, Glycyrrhiza root extract, apigenin, and saw palmetto extract to name a few, in improving hair follicle homeostasis via anti-inflammatory, anti-androgen, anti-microbial, and anti-oxidant action. Here, we present a novel topical serum, REVIVV®, that contains a proprietary blend of phytochemicals designed to stimulate hair growth, reduce shedding, and restore homeostasis to the hair follicle. The serum’s safety and efficacy were assessed in 150 participants in a real-world clinical setting. Findings demonstrate that twice-daily use of the serum significantly improves hair growth, and reduces shedding after 8 weeks of use. All participants rated the serum as easy to use and stated plans for continued use. Overall, the topical serum REVIVV® showed evidence of good efficacy related to hair growth and had positive cosmetic properties warranting further evaluation in clinical studies.

Carboxytherapy Mask as Post Nanofractional Radiofrequency Treatment for Improvement of Facial Skin Quality and Photoaging.

BACKGROUND: Skin rejuvenation can be achieved with minimally invasive treatments using energy-based devices that feature reduced side effects and downtime. Post-treatment care is key to minimize any potential side effects and skin reactions such as erythema, dryness, or dyschromia. OBJECTIVE: The objective of this study was to evaluate the efficacy and patient satisfaction of a novel carboxytherapy gel mask compared with petroleum-based lanolin-containing ointment to accelerate wound healing facial post-nanofractional radiofrequency treatment. METHODS AND MATERIALS: Ten subjects were enrolled in this pilot, prospective, randomized, single-blind study and randomized into two arms. One arm received one nanofractional radiofrequency treatment with ointment right after and four consecutive days of ointment applications twice a day, while the second arm followed this regimen with a carboxytherapy gel mask application right after and four consecutive days after treatment. Investigator, safety, and patient assessments were conducted at 24 hours and one-week post treatment. Safety was monitored throughout. The primary endpoint was defined as the degree of investigator global assessment (IGA) in photodamage, pigmentation, and wrinkles using standardized photographs. Secondary endpoints included investigator-rated degree of erythema, edema, crusting, exudation, percentage healing, improvement of skin quality, and patient satisfaction. RESULTS: Nine patients completed the study. There was improvement of one degree in IGA for photodamage, pigmentation and wrinkles in all patients using the carboxytherapy gel mask at the one-week follow up. Blinded investigator ratings showed significant improvement of dryness, erythema, edema, crusting, and percentage healing at the 24-hour follow up, with all patients remaining the same a week post treatment. All patients in the carboxytherapy group were satisfied with the treatment and had no adverse effects. Three patients in the petroleum-based lanolin-containing group experienced mild edema and acne breakout that resolved two weeks after treatment. CONCLUSION: Carboxytherapy delivered via a gel mask after skin rejuvenation procedures is a safe and effective strategy to improve clinical outcomes and reduce post-treatment side effects.
