These Lactic Acid Serums Prove That Everyone Can Exfoliate

Save this story Save Story Save this story If you’ve ever wanted the glow-boosting benefits of an exfoliating acid without the intensity of stronger options, the best lactic acid serums may be your sweet spot, as lactic acid is generally gentler than other alpha hydroxy acids (AHAs), such as glycolic acid , thanks to its larger molecular size. “ Lactic acid is a gentle exfoliating acid that’s naturally derived from dairy products and is part of the AHA family,” says Mamina Turegano , MD, a board-certified dermatologist based in New Orleans. (Despite its milk-related origins, the lactic acid used in skin care today is typically synthetically produced.) “Lactic acid dissolves away dead skin cells to make skin look smoother, brighter, and more radiant—but unlike some stronger acids, it also has hydrating properties, so it tends to be more tolerable for dry or sensitive skin ,” she says.
