Do you have dry skin? Then you may have heard of lactic acid. Here’s everything you need to know about this super ingredient that’s making waves in the beauty world.

Lactic acid belongs to the category of alpha hydroxy acids, i.e. AHAs. These acids are more or less potent depending on the size of their molecule, the concentration, the pH of the final formula and their combination. They have a peeling effect that exfoliates the skin, while working as an antioxidant and stimulating the production of other active ingredients in the skin such as hyaluronic acid.

Lactic acid, on the other hand, comes from plants and foods. As you might have guessed from its name, this active ingredient comes from milk. In fact, it is the effect of fermented milk. And, as strange as it may sound, it’s become dry skin’s best friend. The reason? It has great benefits.

Benefits of lactic acid

Improves the skin’s lipid barrier.

Prevents skin dehydration, keeping the face hydrated, healthy, beautiful and juicy.

It is a powerful antioxidant that gives luminosity to the face, avoiding dullness and oxidative stress.

It has an anti-ageing effect, as it stimulates the production of hyaluronic acid as well as collagen and elastin in the skin.

Another of its great effects is that it is depigmenting, improving the tone of the dermis, increasing the ceramide content and reducing the size of sun spots.

It is a powerful cellular renewer that improves skin texture, combating acne marks and smoothing wrinkles and expression lines.
