The use of lactic acid in skincare can be traced all the way back to the illustrious Cleopatra in ancient Egypt. She is rumoured to have bathed in donkey’s milk in order to keep her skin looking youthful and radiant. Although this treatment may not be very accessible or sound very luxurious to us now, there is some science to back it up as legitimate.


As milk ages, it creates a substance called lactic acid as a product of fermentation. Lactic acid has been known to have exfoliating and hydrating properties which can be great for your skin. Although it’s unlikely that Cleopatra was aware of the chemical reactions taking place in her extravagant, lacteous baths, she was spot-on as an early advocate for this acid.



Lactic acid is part of a group of naturally occurring compounds called alpha-hydroxy acids (AHAs) which are heralded for their benefits for the skin. AHAs work by loosening and removing dead cells on the uppermost layer of your skin (epidermis) to reveal newer and healthier ones underneath. This is called cell turnover. Increased concentrations of AHAs can penetrate deeper into your skin, into the dermis, and remove more dead skin cells.


Lactic acid is one of the milder AHAs meaning it can be a good choice for people with sensitive skin. If you have tried a different AHA in the past and found it to be too harsh or irritating, lactic acid could be a better fit for you. Importantly, increased cell turnover can make your skin more vulnerable to UV thus, applying sunscreen becomes even more important if you plan on incorporating an AHA into your routine.



  • Hydration: increased cell turnover exposes newer skin cells with greater moisture retention than dead ones.
  • Brightening: deep exfoliation can reduce the appearance of uneven skin tone and hyperpigmentation to leave your skin looking luminous
  • Anti-ageing: lactic acid can promote skin firmness through increased collagen production to help fight wrinkles, fine lines, and other signs of ageing
  • Anti-acne: studies have found that lactic acid can decrease the occurrence of acne by regulating oil production from your pores.


Toners can be a great way of incorporating the exfoliating properties of lactic acid into your life. As they tend to include lower concentrations of key ingredients, toners are often less irritating to your skin, while still delivering the rejuvenating benefits of lactic acid.



Here we have assembled a list of our pick of the best lactic acid toners, just for you!

Glo Skin Beauty Hydra-Bright Pro 5 Liquid Exfoliant

Glo Skin Beauty Hydra-Bright Pro 5 Liquid Exfoliant $56

By harnessing the exfoliating capabilities of AHAs as well as polyhydroxy acids (PHAs), the Glo Skin Beauty Liquid Exfoliant can decongest your skin to reveal a smoother and softer complexion. PHAs tend to be larger in size as compared to AHAs meaning they will not penetrate as deeply into the epidermis. This makes this product a good option for those of us with sensitive skin who find some AHAs to be too harsh.



Lactic acid is one of the gentlest AHAs you can find. Because it’s so mild and doesn’t disrupt the pH of the skin, it’s considered safe even for sensitive skin types.


You can help this gentle chemical exfoliant do its job even better by pairing it with the right ingredients, such as:



Hyaluronic acid is touted as one of the best humectants out there and, as you know now, lactic acid is also a humectant. By using these two together, you’re giving your skin the best chance at holding onto moisture throughout the day. Plus, because one of lactic acid’s properties is helping you shed dead skin cell build-up, it really clears the way for your hyaluronic acid to penetrate the deepest layers of the skin and do its job. Find it in serums, moisturizers, and creams that you’ll use after you’ve toned.



Ceramides are skin-replenishing compounds that deliver moisturization to the skin. Using it in a serum, cream, or moisturizer after you’ve toned with lactic acid allows the humectant properties of lactic acid to lock in all the moisture that ceramides deliver. Ceramides also strengthen the skin barrier, and the more you use them, the stronger that barrier gets, so it’s less prone to irritation. Pairing lactic acid with a ceramide-rich skincare routine means lactic acid has even less chance of causing any irritation.



Lactic acid acts as an exfoliant that sheds old skin cells so that new skin cells can make their way forward. To protect that fresh skin from burning or longer-term UV damage, you must use a sunscreen. If you’re using a lactic acid toner, and you’re using it every morning, that means adding sunscreen to the last step of your skincare routine.




By contrast, you can really mess with your skin by pairing lactic acid with the wrong ingredients. These include:



Vitamin C is essentially acidic (that’s how it fades dark spots). Too much acid is a skincare no-no, especially when it comes to vitamin C and lactic acid. Used together, they’ll cause an imbalance in the pH level of the skin and render each ingredient ineffective. The only way to get around this is to use one active in the morning and the other at night.



This is a potent skincare active and it requires the right skincare pairings to work correctly. Lactic acid is not part of those pairings. Because retinol works to wipe away dead skin cells and lactic acid does the same, using these together can cause excessive dryness and irritation.



Benzoyl peroxide is used in skincare to treat mild to moderate acne. It’s an antiseptic that reduces bacteria on the surface of the skin. But a common side effect of this ingredient is dryness and peeling of the skin. That’s not something you want to combine with an exfoliating agent, because it can quickly lead to extreme dryness, redness, and irritation.



Lactic acid can address a variety of different skin issues, making them a great choice for people in all stages of life. For ageing skin, they can improve the appearance of wrinkles, lines, and dark spots while they can also balance moisture levels and deter acne breakouts, a major concern for every teen. Toners can be a great way to incorporate lactic acid into your life, as they are formulated for daily use, and are available in enough varieties that even those with sensitive skin can find one that fits their needs.
