The Clean Beauty Dossier: What is Lactic Acid?

Skintellect's Clean Beauty Dossier is a series where we highlight our favorite good-for-you, non-toxic beauty ingredients that promote healthy, glowing skin. Each edit features a list of coveted products: face, body, and gut, that we have recommended just for you.

WHAT EXACTLY IS LACTIC ACID?            

The not so science-y explanation is that Lactic Acid is sour milk. But hear us out, it's a little more than that when it's backed by research and science on how it helps with breakouts and fine lines. Ultimately, it is a form of alpha hydroxy acid, lactic acid is known as a peeling agent or exfoliant that is commonly suitable for acne-prone skin.
 

WHAT ARE THE SKIN BENEFITS?

Good for sensitive skin, as an hyper-effective exfoliant, lactic acid is essential for speeding up cell turnover rate, kill skin infection and acne causing bacteria, and help with skin firming to relieve a brighter, healthier looking skin. Ideally, if your skin is prone to acne, we recommend using the selections, or similar, to perform surface treatments for a more "polished" appearance. Think: smooth, firm, and brighter (not lighter) complexion.

HOW TO USE IT

Typically found in serums, toners, and exfoliants, start slow by applying small amounts to clean skin during your nighttime routine. Avoid excessive sun exposure when including acids in daytime routine.

 

AVOID USING LA WITH

Retinol, other alpha hydroxy acids (unless formulated with), and benzoyl peroxide. Also avoid using on peeling, sensitive, and compromised skin. Always use sunscreen.

3/4

4/4

Gentle enough for everyday use (but still wouldn't recommend to), this multi-purpose AHA tonic / toner has uber outstanding benefits including exfoliate, brighten, tighten, and hydrate to revive deprived skin.
