Lactic Acid is incredibly effective at resurfacing skin without leaving it dry or tight (which is why most skin types can use it, including those that are acne-prone). In boosting skin cell turnover, Lactic Acid helps resurface and refine to improve the look of discoloration, fine lines and wrinkles, and blemishes.

It depends on your skin type and your regimen (context is crucial in skin care!), but Lactic Acid can be used once per day, if your skin tolerates it well

When formulated with and used properly, Lactic Acid is not harmful to skin. It’s important to note that—as with any ingredient, especially acids—you should always test how your skin might react before using it all over or regularly. Overuse can lead to redness and irritation, and improper sun care will increase skin’s photosensitivity.

Lactic Acid pairs well with hydrating ingredients like Hyaluronic Acid, Sodium Hyaluronate, or Squalane.

Lactic Acid is one of the gentler AHAs due to its larger molecular size. It works at the surface to exfoliate and refine skin, and because it isn’t able to penetrate as deeply as Glycolic Acid (for example), it’s less likely to disrupt skin’s outermost barrier and cause irritation.
