Retinoids are synthetic forms of Vitamin A. Vitamn A has an intriguing history in Dermatology, dating back decades to when it was recognized that toxic doses of Vitamin A led to a severe desquamation or peeling of the skin (as well as liver damage!).
Since that time, both topical and oral refinements to Vitamin A have been developed, accentuating the positive effects of retinoids in skin care and even cancer treatment.
Once of the first widely used topical retinoids was Retin-A or tretinoin liquid. This strong retinoid preparation was effective in treating the closed pores and pustules and acne, but was often accompanied by excessive skin irritation.
Newer formulations of retinoids include Retin-A Micro, which incorporates the tretinoin into a moisturizing cream which lessens the irritation potential.
Other retinoid creams include, among others:
- Prescription product Differin (adapalene)
- Prescription product Tazaorac (tazarotene) which is used for both acne and psoriasis
- Over-the-counter RETINOLS (NOT TRETINOIN), which are advertised to improve wrinkles and skin texture.
Caveat: Retinoids are not recommend during pregnacy, nursing or while trying to become pregnant. |
