In reply to Rachel. Rachel, yes, you can use only BHA. I guess you could alternate them, but it's BHA that's gonna benefit your skin more, so just stick with that.

In reply to Poppy B.. Poppy, yes, the alcohol helps the hyaluronic acid penetrate the skin, and makes the texture thinner, too. Unfortunately, though, that's also one of the alcohols that can be drying. :(

Very informative and great post as always! I wanted to ask if oily skin girls can omit the use of AHA and only use BHA.. Or should we use a combination of both?

I am horribly ignorant when it comes to chemistry and biology, but I do know that there are a lot of different kinds of alcohols. Whereas rubbing alcohol (Isopropyl alcohol) is extremely harsh and drying, others, like SD Alcohol 40, (ethyl alcohol–the kind we drink) allow active ingredients to be absorbed. I’m guessing the alcohol is in this serum to allow the hyaluronic acid to get into the skin.
