Ingredients Lab: What Does Lactic Acid Do For Your Skin?

Take a deeper dive into how and why we use lactic acid in our effective, science-led formulations to give you the ultimate in skin confidence.  

Read on to discover more about this buzzworthy skincare ingredient, why we use it in our transformative therapies and how it can help bring dry, dull and dehydrated skin back to life with lasting radiance… 

What Is Lactic Acid?

Lactic acid is part of a group of chemical exfoliants called alpha-hydroxy acids (AHAs) that are used in a wide variety of over-the-counter and professional skincare treatments. Compared to super-potent glycolic acid, lactic acid is a combination of AHA’s and humectants, meaning that it is a milder exfoliant and is therefore more suited to those who suffer with irritated, dry or sensitive skin. 

It is naturally found within milk and dairy products and is what gives yogurt and sour milk its unique tang, but nowadays it can be synthetically produced. Due to it being suitable for all skin types, the effects of lactic acid on the skin have been widely recognised by skincare scientists and dermatologists as it helps to reveal a brighter, fresher and more radiant complexion.  

What Does Lactic Acid Do For Your Skin?

Lactic acid is a mild exfoliant that helpto slough away dry, dull and dead skin cells by stimulating and speeding up the process of the skin’s cell renewal. Alpha hydroxy acids (AHAs) help exfoliate and renew skin texture; however, the effects of lactic acid have an extra added benefit that can’t be achieved from using regular AHAs. Along with its exfoliating properties, it is the most hydrating alpha hydroxy acid because it also helps to improve the skin’s natural moisture barrier, increasing your skin’s ability to maintain water and leaving it feeling more moisturised and less dry. 

This hero ingredient also helps to prevent skin-ageing by stimulating collagen production, reducing the appearance of fine lines and wrinkles and helping to increase skin’s firmness. If you suffer from hyperpigmentation, overtime it can also help to fade sun spots and age spots caused by too much sun exposure.
