When I was receiving a facial several years ago, the esthetician suggested I try this line of products. (And she wasn’t trying to sell it to me because they didn’t stock this). I tended to have issues with Adult Acne – annoying large cysts along my jawline and they seemed to last forever. Within a short time of using this line of products, they stopped appearing and I just won’t go back to using anything else. I have been using Aqua Glycolic for at least 3 years now and my skin looks and feels so much better! And the nice side effect is that I don’t tend to use as much concealer or base makeup because I don’t need to cover much up. For anyone with Adult Acne issues, I recommend trying these products. Hope you are as happy with the results!
