Retinol, also known as vitamin A, is a cosmetic ingredient often found in anti-aging products like facial creams, serums, and eye creams—because it can be aging skin’s best friend. It can minimize the appearance of wrinkles, improve uneven skin tone, shrink the look of enlarged pores, and reignite a feeling of firmness and radiance.
It's important to remember that all vitamin A derivatives must convert to retinoic acid to be effective and that the more conversion steps the less effective it is.
Vitamin A chemical name is retinol, the alcohol form of vitamin A as it occurs in nature.
In the skin retinol is first oxidized into retinal then retinoic acid.
I favor encapsulated retinol, retinal or the cosmetic base made of PEG, PEG 4000 to enhance the penetration of retinol thus increasing its activity.
independent of the type of retinoid you are using GO SLOW!
Use it once the first week, Twice the second week, 3 times the third week etc.
If your skin gets dry or itchy stay where you are.
If your skin is ultra sensitive or dry, leave it on 15-30 minute then wash it off.
