Taking care of your skin is an important part of looking and feeling your best. Whether you’re just starting to take your skincare seriously or you’re renewing your commitment, getting great results is all about finding the right products for your skin.  Glycolic acid and salicylic acid are two ingredients that you’ll find in a number of skincare products. But what do they do, and how are they different? Here’s what you need to know.  

What is glycolic acid?

Glycolic acid is an alpha-hydroxy acid (AHA), a group of naturally occurring fruit acids. Derived from sugar cane, glycolic acid is a key ingredient in a wide variety of skincare products in part because of its exfoliating properties. It works by loosening up the outer layers of dull, dead skin cells to reveal the fresh new skin beneath. The exfoliation process also helps to treat pigmentation issues and prevent acne breakouts by clearing away the gunk that leads to clogged pores.  Glycolic acid has a smaller molecule than other AHAs, which allows it to penetrate the skin. So in addition to optimizing skin health on the surface, it also works below the surface by stimulating the production of collagen and minimizing the appearance of wrinkles and fine lines. 

Skincare products containing glycolic acid come in a range of different formulas, from more gentle toners, cleansers, and at-home peel pads to medical-grade chemical peels that should only be applied by experienced cosmetic practitioners. 

What is salicylic acid? 

Salicylic acid is a beta-hydroxy acid (BHA), a group of naturally occurring acids. Derived from willow bark, salicylic acid is a key ingredient in many anti-acne skincare products in particular. Like glycolic acid, salicylic acid exfoliates the upper layers of skin to remove the gunk and reveal the fresh skin beneath. One of the main differences between the AHAs and the BHAs is that the former are water soluble and the latter are fat-soluble. While both glycolic and salicylic acids can penetrate the surface of the skin, the salicylic acid can go deeper,  which allows it to get down into the pores and clean them from within. In addition, salicylic acid helps to reduce inflammation, giving it yet another advantage as an ingredient in acne medications. 

Skincare products containing salicylic acid include cleansers, toners, serums, gels, creams, acne spot treatments, and chemical peels. 

Glycolic acid or salicylic acid: Which is right for you? 

When it comes to choosing skincare products, the best way to determine the right products for your skin is to work with an experienced skin care professional who can evaluate your skin and understand your specific needs. But in general, products containing salicylic acid as a main ingredient are best for oily, acne-prone skin, and treating whiteheads, blackheads, and deeper issues with clogged pores. Products containing glycolic acid as a main ingredient will work best for mild hyperpigmentation, fine lines and surface wrinkles, uneven skin tone, and enlarged pores.
