Which acid should you choose?

AHAs are primarily used for:

• mild hyperpigmentation like age spots, melasma, and scars
• enlarged pores
• fine lines and surface wrinkles
• uneven skin tone

Although AHAs are often marketed as safe for all skin types, you’ll want to take care if you have extremely dry and sensitive skin. You may need to gradually work up to daily use to avoid irritating your skin.

BHAs, on the other hand, are primarily used for acne and sun damage. These products go deep into your hair follicles to dry out excess oils and dead skin cells to unclog your pores. Because of these effects, BHAs are most suitable for combination to oily skin. Lower concentrations may be used to help calm sensitive skin. You may also have more success with BHAs if you wanted to reduce rosacea-related redness.
