Theoretically speaking, acid first or....? Login/Join

Dr. Pickart,

I know that you've suggested one active at a time.

For me, I'd like to use both AHA & copper peptides in the evening.

I understand that it is better for us to slough off the dead skin first before applying copper peptides.

However, I find that if I apply Lactic Power 10 first, I find that Skin Signals Serum or CP serum cannot penetrate well.

What do you think?

1. stick to the principle of AHA first; or

2. use thinner product first (like SS serum or CP serum) and then thicker one (LacSal Cream), or

3. use AHA first and cleanse it off 1-2 hours later and then put on CP/SS serum

Hey Carrot Smiler,

Theoretically, acids first for exfoliation waiting about 20 - 30 mins before applying CPs.

When using a Serum CP at the same time of day, then use a Serum Hydroxy to get the best absorption -or - use a Cream CP after LacSal Cream.

I too prefer LacSal Cream, so if you did not feel that your Skin Signal Solution is absorbing, then after 30 min to an hour of applying - rinse your face, then apply your SS.

That should give you the best of BOTH worlds with maximum effectivness.

Dear carrot:

The other option would be to use an oil-free hydroxy acid liquid rather than a cream that is going to be a bit challenging to use if you are applying a serum on top.

LacSal Serum, which is also 10% hdyroxy acid, works quite well as an exfoliator just as Lactic Power 10 does.
