Rise of stem cell therapies in aesthetics.

Stem cells have the ability to self-renew and differentiate into other cell types, which forms the foundation for their use in regenerative medicine and cosmetic dermatology. Adipose-derived stem cells have proven particularly attractive in aesthetics given their relative ease of collection and abundance. Stem cells have been employed for the treatment of androgenetic alopecia and skin rejuvenation with promising results, but their incorporation into cosmeceuticals is still in its infancy. Despite promising preclinical data and small clinical studies, additional randomized, controlled trials and standardization of treatment are needed to truly understand the place of stem cells in the aesthetics arena. We review the current literature and discuss current controversies and debates.
