Which one is the best to use if you are using retin-a at the same time? Is there any better substance to add in a facial cleanser than these? Is glycolic acid the best AHA?

I just got some Retin-a Micro samples, and am going to carefully try them as a way of getting my skin used to retin-a before switching to the vastly cheaper generic 0.025% stuff. As part of this plan, I've stopped using alpha hydroxy acids (in this case, daily glycolic acid at night) a week in advance. Is this reasonable, or am I just being paranoid about the AHA? If everything is cool with the retinoic acid, I'll start adding the AHA back in at some future time. I really don't know if I need to be concerned about this or not.

Salicylic acid exfoliates the surface of the skin and inside the pores as well and has an anti-inflamatory property.
GA exfoliates only the surface of the skin.

how do they mix with retinoids if at all?
I merely figured out that my skin does cope well with retinoids+salicylic acid daily, though, my skin is used the heavy abuse due to acne.

PM: you use it on clean skin wait till it is absorbed then apply Tretinoin. (It can sting since the Tretinoin penetrates deeper).
Follow with usual prosedure.

AM: Use high SPF+UVA protection.

U can. Exept it'll strengthen each others effects hence it can be very irritating and/or drying.
