There is much more to lactic acid than a skin exfoliator. To reap all the benefits of age-defying lactic acid, use one of the many formulas on the market.
Lactic acid is now present in several types of skincare products: from serums and sheet masks to moisturizers, acid lactic can help with many types of skin concerns.
What is lactic acid?
Lactic acid is derived from sour milk, but most lactic acid formulas in skincare are synthetically produced. If you are wondering how it works, it aims at exfoliating the skin by lifting the upper layer of dead and decaying skin cells, resulting in a younger, glowy complexion and it also stimulates collagen production for a suppler appearance.
What’s good about lactic acid?
Lactic acid can be used in most skin types and it works great to reduce hyperpigmentation and scarring, yet it is gentler than other acids –due to its larger molecule size. This is why it is tolerated by most skin types and it is a natural humectant, it can be used in the face and body. If you suffer from keratosis pilaris, this could be the answer for you.
How to use it
As lactic acid is an exfoliating acid, you have to pair it with gentle products such as niacinamide or hyaluronic acid for more luminous and hydrated skin. Make sure you don’t use lactic acid with other exfoliants like benzoyl peroxide or retinol because it might irritate your skin.
Apply it after cleansing your face and before your serums so the acid is absorbed into your skin and serums can penetrate after this type of exfoliation. You should never apply lactic acid if you are going out, you have to do it before going to bed –because it could make your skin more vulnerable to UV damage. And in the morning do not skip your sunscreen application.
As a final piece of advice, lactic acid is gentle, but it is still an acid, so never apply it to irritated skin and start by using it once or twice a week to test how your skin reacts.
