Who could’ve guessed that expired, sour milk could do wonders for your skin? Although this may sound odd, it’s true! A compound found in spoiled milk called lactic acid has been shown to have several health benefits, including those for your skin. This has led to a remarkable uptick in products touting the benefits of this exfoliating acid.

 

WHA IS LACTIC ACID?

Lactic acid is a form of alpha hydroxy acid (AHA) which is a group of exfoliants commonly found in skincare products. You may be more familiar with lactic acid’s counterparts like glycolic acid, citric acid, and malic acid. AHAs work by removing dead cells from the top layer of skin, leaving your face feeling smoother and promoting skin firmness. For this reason, they are often found in chemical peels, serums and toners.

Lactic acid is the result of fermentation. If you remember anything from high school biology, you’ll know that fermentation is the process of breaking down sugars into smaller molecules that can be used as energy. When this happens in milk, the sugar in question is called lactose, which ferments to produce lactic acid.

 

WHAT ARE THE BENEFITS OF LACTIC ACID?

  • Research indicates Lactic acid fights acne: lactic acid has been shown to reduce the incidence of acne lesions as well as has been suggested to kill bacteria that can cause breakouts based on studies
  • Promotes skin firmness: at higher concentrations, lactic acid can penetrate deeper into the skin to support increased skin firmness and reduce the appearance of wrinkles and other signs of ageing
  • Reduces the appearance of hyperpigmentation: increased cell turnover as a result of lactic acid use can help treat uneven skin tone.
  • Hydrate skin: as dead skin cells are shed, newer skin cells are revealed that can retain moisture better than old ones

Tata Harper Resurfacing Serum

Tata Harper Resurfacing Serum $92
This daily treatment from Tata Harper incorporates both AHAs and beta hydroxy acids (BHAs) to help unclog pores and moisturize skin. BHAs differ from AHAs in that they can penetrate deeper to remove excess sebum that AHAs alone cannot reach. This can create a smoother and more luminous appearance overall. Created with dull and uneven skin in mind, this serum also includes ingredients rich in antioxidants to help combat the effects of free radicals, which can cause fine lines and wrinkles.

 


 

Elemis Dynamic Resurfacing Skin Smoothing Essence

Elemis Dynamic Resurfacing Skin Smoothing Essence $90
A skin essence packed full of powerful nutrients aimed at gently exfoliating skin, Elemis’ light, milky essence uses Tri-Enzyme Technology to promote increased cell turnover which works to resurface your skin.

The inclusion of another powerhouse ingredient, birch sap, has been shown to deliver hydration to the skin quickly and effectively. When taken all together, it is no wonder that this formula is a customer favorite!

This formula seeps into the skin easily to provide chemical exfoliation without any of the irritation you would expect from such potent ingredients. An added bonus is that this serum, like all products from Drunk Elephant, includes zero essential oils, silicones, or fragrances that can have harsh side effects on your skin.

FINAL THOUGHTS

Lactic acid serums can be great for those of us looking to slough off some dead skin cells to reveal our best skin. While some of our picks focus on hydration with the inclusion of ingredients like hyaluronic acid, others target signs of aging by including ingredients with antioxidant properties that can protect your skin’s youthful glow. Either way, by incorporating AHAs like lactic acid, all of our choices are sure to leave your skin glowy and radiant.
