How to use lactic acid

Depending on the strength, it can be used to chemically exfoliate, moisturise or as a treatment. In low strengths, the acid hydrates to prevent cell water loss. Furthermore, it reduces dehydration. In larger strengths, lactic acid effectively exfoliates to eliminate dullness and rough skin patches. It can also work on the deeper layers of the skin to boost cell turnover and improve collagen production.

Lactic acid tends to be gentler than glycolic acid so those with sensitive skin types may find it more suitable. If you intend to use a lactic acid product on its own then use it after toning and before you apply moisturiser. It’s best to avoid using other AHA’s, like glycolic acid, at the same time of day.
