What is Tartaric Acid? Why this Skincare Ingredient Is About to Get Buzzy

What are the benefits of tartaric acid in skincare?

1. It’s a gentle exfoliator

Dr. Robinson tells us tartaric acid belongs to the alpha hydroxy acid family, also home to glycolic and lactic acids which we’re huge fans of thanks to their gentle nature. AHAs gently remove dead skin cells from the uppermost layers of your skin, so they’re known to be less irritating than some other exfoliating acids. If you’re looking to smooth your skin’s texture and brighten up dullness, Dr. Robinson says, “Look for [tartaric acid] as an ingredient in a chemical exfoliant or serum. These are products packed with high concentrations of active ingredients.” Tartaric acid, like other AHAs, is great for almost all skin types—sensitive skin, dry, combo, oily—all can benefit.

As for side effects, Dr. Robinson cautions,” There is always the risk of allergic reaction or skin irritation, however tartaric acid is generally well tolerated on its own. Always check the full ingredient list to avoid accompanying known allergens.”

Our pick: Try REN CLEAN SKINCARE Glycol Lactic Radiance Renewal Mask if you’re looking for an easy and gentle exfoliator that’ll majorly up your glow. This cult-favorite formula is made with (you guessed it) tartaric acid, along with some of our other fave AHAs like lactic, glycolic, and citric to exfoliate and minimize the appearance of fine lines and wrinkles.

2. It can help hydrate and heal

If you’re struggling with skin conditions like keratosis pilaris or if your skin just needs some TLC, tartaric acid can help. It has keratolytic properties, which means it helps dissolve skin flakes or tougher layers of skin. This, in turn, helps improve the efficacy of other topical medications by allowing them to be better absorbed into your skin’s surface. Tartaric acid also helps bind moisture to your skin, which is useful for treating dry skin conditions.

Our pick: All skin types, especially sensitive will benefit from this JUICE BEAUTY Prebiotix™ Instant Flash Facial. It’s made with tartaric acid to exfoliate, and the brand’s gommage beads or “smart sensors” that dissolve into skin when too much pressure is applied to make gentle exfoliation a no-brainer. Plus, it’s hydrating so it won’t strip your skin of moisture.

3. It’s rich in antioxidants

Because it’s derived from antioxidant-rich fruits, tartaric acid is a great source of antioxidants for your skin. According to Dr. Robinson, “It’s for the same reason that the grapes in wine are touted as having antioxidant properties.” Antioxidants help protect your skin from damage caused by free radicals and environmental aggressors like UV rays, pollution, and more. Another reason to love? Antioxidants can help prevent and reduce the signs of aging brought on by free radicals.

4. It keeps your products’ pH levels in check

If you check your ingredient labels, you may notice tartaric acid in more skincare formulas than you expect. This is because tartaric acid has an important role in keeping your products stable to minimize skin irritation. Dr. Robinson says, “Unlike other acids which may disrupt pH, tartaric acid actually helps to stabilize other acids to regulate a formula's overall pH. This makes it a popular addition to other AHA product formulas.” That’s right, now only does tartaric acid have its own skincare benefits, it’s used to make sure other acids don’t alter a products’ pH to potentially irritating levels.
