Skin Benefits of Lactic Acid

It’s often considered to be the gentle exfoliating alternative to glycolic acid as it is less likely to irritate skin and has hydrating qualities. So it’s preferential for those with very dry skin. It can help diminish dull skin by removing a build up of dead skin cells, thus leaving the skin looking fresh and radiant. In addition, it can help reveal a younger and healthier complexion with its ability to reduce signs of pigmentation, age spots, and acne scars.

However, the benefits don’t end there; it can also help fight ageing. Lactic acid promotes collagen production in the dermis helping to firm up sagging skin and diminish fine lines and wrinkles.

Where Can You Find Lactic Acid?

It can be found in everyday over-the-counter products. From top skin cleansers to skin brightening serums.

A skin cleanser such as the glo-therapeutics Hydrating Gel Cleanser includes lactic acid to soften and hydrate the skin whilst cleansing. In addition, it gently sloughs away dead skin cells to help reduce hyperpigmentation. This formulation works simultaneously to cleanse, correct and hydrate the skin.

skin brightening serum such as the glo-therapeutics Brightening Serum is an ideal skin pigmentation treatment. The lactic acid in this treatment gently exfoliates skin whilst working to improve skin tone and texture. This includes diminishing pigmentation discoloration and fine lines to reveal a younger looking complexion.

Although, if you want something that works a little deeper, lactic acid peels are available. These peels are ideal for those who prefer a gentler peel, but which still, help to improve the complexion and overall youthfulness of the skin.
