Acid means acid in the way that we think it means. Lactic Acid ($6.80), as one would think (unlike Hyaluronic and Ferulic ova there), is designed to break down dead skin. Specifically, it treats hyperpigmentation, age spots, and other situations that contribute to a dull and uneven complexion. It basically dissolves dead skin cells in a super friendly, non-irritating way. Even my super sensitive skin can handle a daily dose and not get irritated..Other benefits include improved skin tone and reduced pore size. However, unlike AHAs like glycolic acid and salicylic acid, which can weaken the skin barrier, lactic acid is milder.
…Unlike Glycolic Acid ($52). Glycolic and Lactic acid belong in the AHA (alpha hydroxy acid) family, that’s why they’re cousins. But Glycolic acid is the more intense cousin. It also has anti-aging properties but it also helps to reduce acne and tighten pores because it has a nice small molecule size, so it penetrates readily. This stuff stings, FYI. I wouldn’t use this every day on my sensitive skin, for example. Maybe 2-3 times a week. I find myself reaching for my glycolic pads in the summers when I’m a grease ball. In the winter, not so much.
We’ve heard of Salicylic Acid in the pimple ads. It’s neighbors with the AHA—it’s a BHA, a beta hydroxy acid. AHA’s are water soluble, BHA’s are oil soluble. BHA’s penetrate through the lipid layers between the skin cells more readily. They penetrate the skin to a deeper level than its acquaintance, AHA. So buh-bye, pimple. It breaks up and dissolves the gunk. Tippy-tip: It works best on whiteheads and blackheads.
Malic Acid: it’s an AHA (you know what that means now! 🥳 woohoo!) and does a plethora of cool stuff, including: hydrating, exfoliating, improving skin smoothness and tone, smoothing wrinkles… and is a humectant, to boot! In conjunction with its exfoliating friends it packs a punch in this Green Apple Peel Full Strength Exfoliating Mask ($48).
