Skincare & Chemistry
Hey, my name is Elizabeth Asher, Phd and I am a skincare chemist based in San Francisco, particularly interested in educating the public about the science behind different popular skincare ingredients. There is a lot of hype marketing in skincare products that do not show results and by understanding key ingredients, we can make more informed decisions about our skincare purchases. I also make DIY dupes of expensive skincare products in my free time.

Ever wondered why you had bouncy skin when you were young? In our younger years, the dead skin cells on our skin’s surface shed quickly, just every few days, and new skin came to the surface. Over time and as we age, this turnover rate slows down. By exfoliating your skin regularly, you can get rid of those top layers of dead skin for better skin texture and complexion.
AHAs are popular ingredients in skin care products for acne, anti aging, or just general moisturizers, but rarely do these products also educate you about how to use an AHA, the benefits they offer or their side effects. AHAs are potent and if you use them without proper care for your skin, they can result in more damage than their intended benefits. This guide explains the benefits, side effects, different types of alpha hydroxy acids, and offer some recommendations for best performing AHA products for skin problems.
Both glycolic acid and salicylic acid are hydroxy acids, but they can be used to tackle different skin issues. They each lightly exfoliate, penetrate the skin and are considered to be active ingredients that should be used with care. And using them properly and regularly can yield fast and long lasting results in skin texture and complexion.
