Hi Jim.
Here's my rundown of the different PC BHAs. I have combo/oily acne-prone skin.
1% BHA solution:
~ Very light lotion that moisturizes just enough, for me, and absorbs quickly to a nice matte finish.
~ I use it every day, on my whole face.
2% BHA liquid solution:
~ A liquid, toner-like formula.
~ It can take quite a while to absorb into the skin. It kind of sits on the surface for about 10 minutes, so some people don't like to deal with this "film". I use it only at night, however, so this absorbtion time doesn't bother me. I use it every night after cleansing my face.
~ This gave me greater results than any other product I've tried for my face! I noticed major clearing in a matter of days!
2% BHA lotion:
~ Some people prefer this because it absorbs faster than the liquid solution.
~ It has a slightly thicker consistency than the 1% solution (lotion). It also contains more moisturizing ingredients.
~ For some people (like me), this has the potential to be pore clogging. This is why I stuck to the liquid.
Also, remember that you can request free samples of all of these from the company! They send packets that last for at least a week, which is plenty of time to find out if the products work for you! Like I said, I saw
MAJOR results from the 2% solution in a matter of days!! I've been using PC BHAs for over a year now.
Good luck!
