What is it?

Lactic acid is a chemical exfoliant that comes from the fermentation of lactose a carbohydrate found in milk. ‌Like glycolic and mandelic acids, this acid belongs to the alpha hydroxy acid (AHA) family. AHAs are water-soluble organic compounds that, in cosmetic formulations, offer unparalleled benefits for the skin.

Benefits for your skin?

Lactic acid has many known perks. It increases cell turnover and helps eliminate accumulated dead skin cells on the epidermis — the top layer of the skin.

After using lactic acid, you’ll notice a brighter and smoother complexion. This AHA exfoliant helps treat moderate to severe hyper-pigmentation. It can fade out age spots and reduce the appearance of wrinkles and highly visible pores. This acid is one of the mildest forms of AHA, so it’s safe to use it on sensitive skin in the right concentrations.

How to use in your skincare routine?

It’s advised that you gradually introduce this exfoliant into your daily routine.

And while most lactic acid products are suggested for use before bed, you should always carefully read the instructions and labels. If you’ve got sensitive or tricky skin, do a patch test with the product before going all the way.

Since AHAs, including lactic acid, work to peel away and soften the top layer of your epidermis, there’s always a risk that your skin can be more exposed to the elements, including the sun.

Therefore, it’s advised that you pair your lactic acid use with a sunscreen or a SPF-containing product.
