This is a very effective retinol, wouldn't recommend for retinol beginners.

Effective Retinol, but sometimes I get a bit too dry in the winter time using this in alternation with salicylic acid

A bit pricy but good retinol after you get your skin used to it! 

I love Paula’s choice and I love this retinol ! If you want smooth young looking skin with a nice tone, go get it!!! No irritation, no itchiness, no dry flacks even though I have sensitive skin! This is a product of a high quality 👍🏻

Ingredients wise this is great! However, it kind of gave me some red patches that burnt my skin and would disappear after 2-3 days. Maybe it interferes with some other products I use , or maybe I should do it once or twice a week and not every single night but I don't have sensitive skin and this shouldn't really happen.
