Question about using products at same time

[autumnash]

Can I use Paula's Choice bha skin perfecting liquid and then Sunday Riley good genes over it?

@autumnash I would personally say "yes."  Although I would use one at night and one in the morning; that's just my preference.  You could also ask PC, but put it under the guise of, "Can I use BHA and AHA together?"

Yes, they are different kinds of acids so you can use them together. Good Genes is lactic (an AHA) so it works on the top layer of skin whereas bhas are smaller molecules and sink further into the skin. I would consider them a once or twice a week pick me up together rather than a nightly thing.
