Acne Vulgaris Topical Therapies: Application of Probiotics as a New Prevention Strategy

Abstract

The skin microbiome is an essential barrier for preventing the invasion of pathogens and regulating the immune responses. When this barrier is disrupted, several dermatoses, including acne vulgaris, may arise. Most people will experience acne starting at the onset of puberty and continuing into adolescence; a significant percentage of those individuals continue to suffer from it into adulthood. Although common, this dermatosis usually has an enormous impact on the self-esteem and quality of life of individuals who suffer from it. An increase in consumer literacy regarding skincare leads buyers to seek out innovative products containing ingredients with proven benefits for their concerns. Probiotics have proven to be an alternative to the use of antibiotics, often associated with undesirable effects, in the treatment and prevention of dermatological disorders such as acne. This review provides a comprehensive analysis of the pathophysiology, risk factors, symptoms, conventional treatment recommendations and main studies emphasizing innovative topical products for acne-prone skin based on probiotics. In addition, the potential advantages, and limitations/challenges associated with the implementation and manufacturing of these innovative skin products are also highlighted.
