In my experience Retin-A has been the Gold Standard for years. I want to break down the differences in formulations available but before I do that understand that this is one of the most effective ways to stimulate collagen production and combined with Vitamin C and skin lightening agents this little guy becomes your game changer. Under the Vitamin A family there are a few retinoids. Retinol, Retin – A and Tretinons , all which are Retinoids and under that same umbrella. ALL of these must convert into retinoic acid in order for it to be effective. Because I get asked this question just about daily. Let’s start with over the counter formulas which are retinols which is a low dose , slow acting version on a retinoic acid and can be found at CVS, Target, Ulta and other over the counter options. Most all skin types can tolerate an over the counter retinol however patients with serious acne conditions will need to use a higher concentration than an over the counter product . Also remember that this low dose retinol has to go through a conversion process for the skin to recognize it.
Next is its sister , retinaldehyde which converts more gently in that it only has to go through one conversion process, I like to start patients here.
