What to expect from chemical exfoliation
This method uses different chemicals, including hydroxy acids and retinol, with enzymes to renew your skin.
While DIY and OTC scrubs can help enhance your skin’s appearance, chemical exfoliation can offer more dramatic results.
As with physical exfoliation, chemical exfoliation can irritate the skin if done incorrectly. If you’re unsure about how to incorporate a chemical product into your routine, see a dermatologist or other healthcare provider for guidance.
Alpha hydroxy acids (AHAs)
AHAs are a group of water-soluble acids typically derived from sugary fruits. Popular AHAs include:
- glycolic acid, which comes from sugar cane
- lactic acid, which is found in milk and pickled vegetables
- citric acid, found in citrus fruits
- tartaric acid, from grapes
- malic acid, found in apples
These acids help peel away the surface of your skin so that new, more evenly pigmented skin cells may generate and take their place.
Depending on the type, AHAs may also help with:
- mild hyperpigmentation like age spots, melasma, and scars
- enlarged pores
- fine lines and surface wrinkles
- uneven skin tone
Beta hydroxy acids (BHAs)
BHAs, on the other hand, are oil-soluble. These acids go deep into your hair follicles to dry out excess oils and dead skin cells to unclog your pores.
Because of this, BHA products are primarily used to treat acne and sun damage.
Salicylic acid is the most common BHA. It’s well known as an acne treatment, but it can also help calm general redness and inflammation.
