can't Dan make AHA+ or BHA+ with SPF IN it

Recommended Posts

seriously, this would make things so much easier...

You can't use AHA without a sunscreen, so why not put it in the AHA?

I think it's a pH thing. Sunscreens, AHA's, and BHA's all need a certain pH's to be effective. I remember reading one time that if an AHA product has spf in it, one or the other (either the AHA or the spf) would not be effective, since they require different pH's to be effective.
