Yes. The mandelic acid molecule is larger than its cousin, glycolic acid, which means it penetrates skin more slowly. This sustained action produces less irritation, allowing the serum to be used on all skin types and with varying skin pigmentation. If you have dry skin, the moisture-restorative properties of mandelic acid and other serum ingredients will help keep your skin feeling supple. If your skin is oily and prone to breakouts, the mandelic acid can help by neutralizing acne bacteria.
