Cosmetic skin lightening use and side effects

Cosmetic skin lightening is a growing dermatologic public health problem that affects communities of color worldwide. Despite well-documented adverse health effects, cosmetic skin lightening continues to be a popular practice among patients of color. Given the US's changing demographics, it is critical for dermatologists to be knowledgeable about the medical impact as well as social and cultural implications of this practice. This review article aims to serve as a primer for the dermatologist on the medical and sociocultural aspects of cosmetic skin lightening, as well as an approach to discuss the issue of cosmetic skin lightening with patients. We conducted a comprehensive PubMed search using the terms 'skin lightening agents,' 'skin bleaching,' and 'depigmenting agents,' and reviewed the literature on cosmetic skin lightening products, active ingredients, and adverse side effects. Herein, we review the prevalence, ingredients, and health implications of cosmetic skin lightening products. We also provide recommendations for counseling patients who practice cosmetic skin lightening in a culturally sensitive manner.
