Earlier this year, I’ve ventured into testing various AHA based products. As your skin ages it becomes more important to find ways to exfoliate beyond a simple sugar and lemon scrub. Fortunately, the break-out period of my life was so long ago that I haven’t had to worry about serums and acids for combination, acne or congestion prone skin in almost 20 years. I think that’s mainly due to diet and exercise. Now, I’m working on improving the texture and integrity of my skin into my 40’s. AHA’S like glycolic acid have been proven help shed the top layer of dull, damaged skin by loosening the glue-like substance that holds skin cells together.
