Intradermal BoNT-A injection may represent a promising new treatment for oily skin

A review of published data has concluded that intradermal injection of botulinum toxin may be a promising new treatment for oily skin. 

The article, which feature in the April issue of the Journal of Cosmetic Dermatology, aimed to review the efficacy and possible treatment mechanisms of BoNT-A on oily skin by conducting a retrospective review of the published data. 

Most studies have suggested that the intradermal injection of BoNT-A decreased sebum production and pore size. Furthermore, this treatment attained high patient satisfaction without significant side effects. BoNT-A effectively decreased sebum production and excretion, which was in keeping with previous studies, possibly via its blockade of cholinergic signaling and its neuromodulatory effects.

The authors concluded that intradermal BoNT-A injection may represent a promising new treatment for oily skin and other relevant dermatological problems, such as enlarged pores, acne, and seborrheic dermatitis. Further study is still needed to determine the specific mechanisms of BoNT-A, and the optimal injection techniques and doses for oily skin and other relevant cosmetic concerns.
