    After applying a 10% lactic acid pH 3.8-4 serum to face, how much time should i wait before applying another product (moisturizer) on top of it?

    If i apply a moisturizer to skin after applying lactic acid exfoliant, doesn’t it increase the pH and reduce the effectiveness of of exfoliator?

    I don’t think a formal test of this has been done so it just becomes a guess.

    My guess is that you won’t notice any difference whether you wait 1 minute or 1 hour.

    @Perry Thanks.
     Looks like AHA is doing it’s job immediately.
