Im using Retin A and AHA already in the PM and want to add copper peptide. Can I apply the CP after the Retin A and before the AHA?

Could I mix the CP with the Retin A and apply together?

I have read that its ok to use AHA with Retin A to enhance absorption. Im not sure about the CP though.

Hi Monica - it depends which type of CP you're using. First generation e.g. Neova are not stable in acids so it's a no no to mix with AHAs and Retin A. Skinbio's (also sold through Diana Yvonne and Platinumskincare) are second generation which are stable with acids and can be mixed with AHA's/used alongside Retin A.

I think it's a little unusual to mix Retin A and AHA - most people couldn't take that so I don't know the answer.

The standard wisdom is to apply Retin A first then layer with CPs. I guess you could experiment with mixing, why not. I'd be inclined to use the acid first then Retin A then CP but I'm certainly not a layering expert. I don't have the patience to do it myself.

I have read about people using retinoid/retinol products with AHAs and CPs. The routines I've seen are AHAs (the lowest pH product) first, then the retinoid product, then CPs.

I think that you are supposed to wait 30 minutes after the AHA and again after the retinol product to derive maximum benefit.

I did this for a couple of weeks myself, following a cleanse then AHA+BHA (biphasic treatment), wait 30 min, Green Cream (a retinol product), wait 30 min., then CPs. I stopped this after a couple of weeks because 1) I ran out patience with this routine (!) and 2) the AHA and Green Cream applied at the same time of day irritated my skin. I don't know how your skin is, though, so maybe you would be fine. I guess you could also try AHAs in the AM and RetinA in the PM (or vice versa).

That's true after retinol/retinaldehyde/Vitamin A - you should wait for it to convert in the skin to Retin A/Tretinoin, but with Retin A it's the final chemical so no need to wait before your next layer.

that's good to know...if I ever go back and try to add a retinoid product I will use one that doesn't require the 30 minute wait!

Yeah. I think that (for now at least) any retinoid/retinol/retinaldehyde product is too strong for my skin. When I tried just the retinol+acids my skin freaked out -- dry, irritated, and breaking out all over the place due to the irritation. I don't think that I would try it again unless I were going to cut way back on my acid treatments. That said, I know that there are other people using retinol + AHA/BHA and doing fine. Maybe it will work for Monica! (Let us know, Monica!)
