Lactic acid is an over-the-counter chemical exfoliant that comes from the fermentation of lactose. It is a carbohydrate found in milk. It is included as a popular ingredient in many skin care products. However, its use is not a new thing. It is believed to have been in use since the time of the ancient Egyptians. If you do not know, let us tell you that Cleopatra (Cleopatra VII Philopator was the queen of the Ptolemaic Empire of Egypt and its last active ruler from 51 to 30 BC.) To keep her skin young, she bathed in sour milk...

Like glycolic and mandelic acid, lactic acid belongs to the alpha hydroxy acid (AHA) family. AHAs are water-soluble organic compounds that, in cosmetic formulations, provide unique benefits for the skin. Let us know what it is and its benefits from celebrity cosmetic dermatologist DrChitraAnand.

What is lactic acid?

It is an AHA, which helps in removing dead skin cells by helping in skin hydration. It also stimulates skin collagen and works better for dry and sensitive skin. The best part is that it proves to be a great ingredient for every skin type.

What are the benefits of lactic acid?

It increases cell turnover and helps to eliminate dead skin cells deposited on the topmost layer of the skin called the epidermis. Apart from this, it also provides many advantages-

Helps to lighten dark spots

Lactic acid is specifically used to treat hyperpigmentation, ageing spots, etc. These spots cause a dull and uneven tone. Lactic acid helps improve skin tone and reduce the appearance of pores.

Provides hydration

Lactic acid helps to smooth and soften rough or scaly skin. It is one of the softest alpha-hydroxy acids and deeply hydrates the skin.

Helps with fine lines and wrinkles

Lactic acid works on the dullness of the skin and helps to make it smooth and even. Apart from this, with its help, the skin looks firm and it helps in reducing fine lines, wrinkles and dark spots.

Supports collagen levels

Since lactic acid helps to lift epidermal cells, it promotes the regeneration of new cells and stimulates the production of collagen and elastin.

Keep these tips in mind-

  • It's milder than other AHAs, and you may find it easier to gradually incorporate it into your skincare routine.
  • Apply it only 2-3 times a week in the beginning. Gradually you can increase the frequency.
  • Don't forget to apply sunscreen after applying it. Sunscreen is an essential part of the skincare routine.
  • Do not apply Vitamin C with lactic acid at all. At the same time, other AHAs should also not be used.
