Benefits of Lactic Acid for Your Skin
Lactic acid can be very beneficial to the skin. Treatments using lactic acid are popular due to their ability to brighten the skin, as well as treat discoloration, sensitive skin, dry or dehydrated skin, and rosacea.
Alpha Hydroxy Acids (AHAs)
Lactic acid is a type of alpha hydroxy acid (AHA), a class of chemical compounds found in products that help reduce wrinkles and lines and improve the overall look and feel of the skin. It is the least irritating of the AHAs used in skincare treatments and is known for its natural moisturizing effect.
AHAs, including lactic acid, are effective in the treatment of age spots, hyperpigmentation and other factors that lead to a dull or uneven skin appearance. An additional benefit of AHAs is reduced appearance of pores.
Lactic acid is the mildest of the AHAs used in skin treatments, making it a better option for people with sensitive skin.
Lactic Acid Peels
Lactic acid peels exfoliate the outer layers of the skin. Like other types of peels, lactic acid peels increase cell turnover and stimulate the production of collagen. Lactic acid also increases the amount of natural barrier lipids in the skin, which can have a hydrating effect.
Lactic acid peels are particularly effective in treating bumpy skin without causing or worsening dryness. They are often combined with small amounts of other AHAs for enhanced results.
Professional lactic acid peels
Like other types of professional chemical peels, professional lactic acid peels are stronger than their at-home counterparts, and therefore offer more dramatic results. The effects also last longer than over-the counter (OTC) peels, so you don’t have to use them as often.
You might consider getting a lactic acid peel from your dermatologist or skincare specialist if you aren’t seeing results from OTC versions but don’t want to use a stronger AHA.
At-Home Lactic Acid Peels
If you’d like to try an at-home lactic acid peel before seeking out the services of a professional, there are numerous options. Here are a few popular at-home products:

Lactic Acid Peel Side Effects and Aftercare
Although lactic acid is milder than other AHAs, the peeling it causes makes the skin more susceptible to sun damage; as a result, it is important to wear sunscreen following a lactic acid peel.
Lactic acid peels can also cause rashes, itchiness and other irritation. These effects are typically mild and dissipate as the skin acclimates to the product.
People who suffer from eczema, rosacea, or psoriasis should not use lactic acid peels. Also, those with darker skin should speak with their primary care provider or dermatologist before deciding to have a lactic acid peel, as this treatment can cause hyperpigmentation in darker skin.
Lactic acid peel burn
It is normal to experience a temporary burning sensation or other skin irritation (tingling, itching, dryness, redness or tightness) following any chemical peel, including a lactic acid peel. This is more common with medium to deep peels than with light peels.
Is it safe during pregnancy?
Due to its mild composition and the fact that it is naturally occurring, lactic acid may be safer for pregnant women than other AHAs. However, if you are pregnant it is important that you speak with your doctor/dermatologist about safety before deciding to move forward with any chemical peel, including a lactic acid peel.
Lactic Acid Peel Reviews
Due to their effectiveness and mild composition, lactic acid peels generally have a good reputation among dermatologists and other skincare professionals.
Patients like lactic acid peels because they are far less invasive than plastic surgery alternatives and milder than other AHA peels. Plus, they can be performed in just a few hours.

Other Skincare Uses of Lactic Acid
Because lactic acid can penetrate deep into the skin, it is also considered an effective and safe treatment against skin discoloration conditions, such as melasma or sun spots (otherwise known as age spots).
However, it cannot treat every skin problem. For example, lactic acid is not effective for skin tag removal. If you have a skin tag, your doctor will likely recommend snipping, freezing or burning it instead.
Dermatologists and skin care professionals are fond of lactic acid’s mild composition, quick cell turnover and ability to trigger the skin’s renewal process.
Professional lactic acid peels can offer superior results that last longer than at-home peels, so treatment does not need to be performed as often.
However, for patients interested in an even milder effect, at-home lactic acid peels may be a better option as they are formulated for non-professional use.
