When it comes to skincare, not all acid exfoliators are equal...
Like many other chemical exfoliants, lactic acid is an increasingly popular skincare ingredient in many a beauty lover’s regime. Here’s everything you need to know about it, and whether it’s right for your skin type.
What is lactic acid?
‘Lactic acid is one of the larger molecules of the alpha-hydroxy acid family, water-soluable like glycolic acid, but stays more on the outer layers of the skin,’ explains The Inkey List co-founder Mark Curry. ‘Our lactic acid acid comes from milk and fruit sugars.
‘Staying on the outer layers of the skin, it un-glues dead cells to reveal brighter, more even skin, as well as provide additional moisture to the outer skin layers.
‘It suits all skin types who want brighter, more even and hydrated skin. This should be one of the first exfoliating acid people go to if they are more sensitive or cautious about exfoliating.’
Lactic acid peel
Max-strength chemical peels are performed by a professional, but it’s possible to buy slightly weaker AHA peels you can perform in the comfort of your own home. Kate Somerville’s ExfoliKate Treatment, for example, is a mega tingling formula that sloughs all the dead skin cells from your face, leaving you positively glowing.
Don’t fancy the fuss of applying a peel and sitting around waiting for it to do its thing? Peel pads, like those made by Skyn Iceland are an easy way to exfoliate fuss-free both morning and night.
Lactic acid serum and cream
These are leave-on formulas enriched with AHA exfoliating prowess and can be left on overnight to smooth out the skin, or applied as a 10-15 minute wash-off treatment.
Similarly, creams gently resurface the skin while you moisturise for a smoother finish to your complexion over time. If you have sensitive skin, higher concentrations of lactic acid may still cause your skin to become irritated, so always do a product patch test beforehand.
