  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.
