I will be discussing the lesser, not-as-well known acids in the Skincare game. There are a few in mind such as Malic, Mandelic, Azelaic & Tartaric Acid. These acids don't seem to be mentioned as often as some the more better well-known ones such as Glycolic, Salicylic & Lactic Acid. I will be briefly breaking down though for you. Just to have a much better understanding. ^_^ Mandelic Acid - This acid with a much larger molecule is derived from bitter almonds. It's a good one for sensitive skin, since because of the molecular structure works more gently than other acids as well. Great for acne, hyperpigmentation, skin texture and fine lines/wrinkles as well as for other anti-aging concerns also. It does function as an exfoliating alpha hydroxy acid but at a slower pace as opposed to Glycolic acid, which is a much smaller molecule in size. Tartaric Acid - Not many studies on this acid as a alpha hydroxy acid & its exfoliating benefit...
