Hydroxy Acids are ubiquitous in aesthetic medicine. Alpha- and beta-hydroxy acids (AHAs/BHAs) are the most widely used ingredients for chemical peels; they have also become popular topical agents for antiaging, hyperpigmentation and acne. In recent years, they have been joined by polyhydroxy acids (PHAs) as a less irritating alternative for patients with sensitive skin. “I recommend AHAs for everybody—antiaging, acne, rosacea patients. It’s really one of the best things you can do for the skin,” says Monica L. Halem, MD, FAAD, a dermatologist in private practice in New York City.

A study published in Plastic and Reconstructuve Surgery (March 2017) examined bacterial biofilm as a possible cause of adverse nodular reactions following treatment with filler injections. Researchers Mayuran Saththianathan, et al, performed an in vitro analysis of the propensity for three classes of filler materials to support biofilm growth; studied the effect of inoculation of filler material through a contaminated surface; and analyzed biopsy samples from patients presenting with chronic granulomatous inflammation following filler administration.

Retinoic Acid Inhibits Melanocytes

A study published in the Japanese Dermatological Association Journal of Dermatology (January 2017) examined the in vitro effects of all-trans retinoic acid (ATRA) on human melanocytes and melanoblasts following treatment with different concentrations and/or an antagonist of the endothelin B receptor (EDNRB, bosentan). The experiments were all repeated at least four times, and data was analyzed via the Mann-Whitney U-test.

Addressing Platysma Bands

A recent study posited that platysma bands are caused by muscular activity during the aging process and are not secondary to skin sagging, and offered a novel approach to managing them.

Patrick Trévidic, MD, and Gisella Criollo-Lamilla, MD, conducted a prospective clinical study of 25 patients who presented with definitive, unilateral, facial palsy following otoneurosurgical treatment, with a focus on the subjects’ anterior neck bands. Patients were followed for up to 10 years.
