What is Lactic Acid?

Lactic Acid is a popular treatment in the skincare arena and is derived from lactose (a carbohydrate found in milk.) However, most forms of Lactic Acid used in skincare today are synthetically made and are therefore vegan friendly.

Similar to Mandelic Acid and Glycolic Acid, Lactic Acid in skincare is classified as an AHA (alpha-hydroxy-acid). AHA’s in skincare stimulate collagen production, reduce pigmentation, soften and remove old, dead skin cells. Lactic Acid in particular also intensely hydrates the skin.

Lactic Acid can be used by more sensitive skins and is known to be less aggressive than other AHA’s as it is a larger molecule and cannot penetrate the skin as deeply as the others or BHA’s.

A powerful ingredient for those with dry, dull skin, Lactic Acid resurfaces and normalises skin cell behaviour. This strengthens the skin’s barrier by encouraging it to make more ceramides which are critical for healthy skin.

Lactic acid skincare products are available over the counter and in professional peeling treatments.

Skin benefits of Lactic Acid

Lactic Acid is active on the top layers of the skin and gently but effectively breaks down old skin cells. This reveals brighter, smoother skin which in turn helps with pigmentation, age spots and any rough or dry skin.

Lactic Acid acts as a humectant to attract water into the skin. This helps to plump fine lines and improve the appearance of the skin whilst also keeping skin healthy.

Reduces pores
Lactic Acid helps to unblock and cleanse pores for those suffering from breakouts or acne.

Why We Use Lactic Acid

“We choose to incorporate Lactic Acid within our professional peeling products as it is fantastic for breaking down skin cells and revealing brighter skin from the outside in. Teamed with other AHA’s and BHA’s, Lactic Acid can be relied upon to exfoliate and unblock congestion, while hydrating upper layers of skin at the same time. The fact that it also helps to build and strengthen skin is an added bonus for us”

Before and After Using Lactic Acid SKINICIAN Products

Take a look at some of our real before and afters taken by customers following their professional Lactic resurfacing treatment:

Who Lactic Acid is best for

Ageing skin, pigmentation, dull or dehydrated skin and those with more visible lines and wrinkles or open pores. As the gentlest form of AHA, Lactic Acid can be used by all.  Those with sensitive skins should slowly introduce Lactic Acid into their routine to ensure the skin can tolerate the ingredient.

Things to Consider Before Using Lactic Acid

It is advisable to do a patch test if your skin is highly reactive or sensitive, if no inflammation or irritation (redness, itching or noticeable peeling) occurs, it should be safe to use the product. It is not advisable to use too many AHA’s, BHA’s or retinoids together in a skincare routine as it may damage the skin's barrier.

Lactic Acid at lower levels 1-4% can be used daily e.g toners or serums.  

Professional peels carried out by a trained facialist or skincare professional are likely to have medium levels of 10-30%. Higher levels of Lactic Acid in a treatment would need to be carried out with a registered dermatologist.

SPF 30 must be used daily when using lactic acid in a skincare routine.
