ABSTRACT:
Treatment of post-inflammatory hyperpigmentation (PIH) in black and asian skin is accelerated from natural healing by use of a composition comprising a retinoid and/or an inhibitor of cytochrome P-450 enzyme-mediated degradation of retinoids, the composition does not require a conventional depigmenting or bleaching agent (such as a hydroquinone) as is typically used. Healing of PIH lesions is accelerated about three to five times from normal healing. Additionally, these compositions are useful separately for lightening black or asian skin.
