Generic vs. Brand Topical Retinoids
Generic topical retinoids such as tretinoin should be just as efficacious as brand name versions. There are different strengths of generic topical retinoids which are denoted by a percentage. The vehicle (type of cream/gel) of the retinoids may vary between generic and brand name which some patients may note is a significant difference, whereas others are unaffected by vehicular subtleties. As always, I recommend discussing your specific condition and use of topical retinoids with a board certified dermatologist.
