Lactic Acid Peels

Information about lactic peels and what they do |



Similar to glycolic acid peels, lactic acid peels are alpha hydroxy acids. Derived from milk, they are very mild chemical peels with little to no downtime. Because lactic acid is a natural human metabolite, there is less chance of an allergic reaction with this type of peel. Therefore, they are a good choice for first-time peel users or those with sensitive skin. Dry or oily skin types can also use this peel and get good results. Lactic acid is especially good for mature skin.


What do they do?

The benefits of lactic acid peels include:

  • Exfoliating the surface of your skin
  • Deep cleaning pores
  • Fading dark marks
  • Improving hyperpigmentation
  • Brightening and lightening skin
  • Improving the appearance of light wrinkles
  • Stimulating natural collagen production

Lactic acid vs. Glycolic acid

Texture wise, lactic acid is a thick (but not thick like honey), sticky, and yellowish solution while glycolic acid is a very watery, clear liquid. Lactic acid is more expensive, which is why lactic acid facials usually cost more. Both peels yield similar results, though lactic acid peels are less harsh and tend to fade hyperpigmentation better.

If you are deciding between a glycolic acid peel and a lactic acid peel and don't know which to get, go with lactic acid if you have never gotten a peel before or if you have lots of dark marks you want to fade. Once you find you can tolerate lactic acid just fine, you can try using glycolic acid the next time.


What to expect

During the peel, your skin will feel warm and turn pink. This pinkish color could last for a few hours or few days post-peel, but it's normal and will go away on its own, as long as you wear sunscreen and stay out of the sun. Lactic acid peels don't burn or make your skin physically peel, unless it's a really high concentration.

Because lactic acid peels are mild, they can be safely used 1-2 times per week. However, it depends on your skin and what other products you are using. For example, if you're on retinoids, it would be smart to not be as aggressive with lactic acid peels because your skin is already getting a strong dose of exfoliation.

Like with all chemical peels, it will most likely take multiple treatments to see results. 1-2 treatments for 6-8 weeks will usually give you optimal results. There will also be some side effects, though not as pronounced as other stronger or deeper peels. Instructions and precautions for lactic acid peels are the same as the ones for glycolic acid peels, so please consult that section for more information.
