The Ordinary Mandelic Acid 10% + HA is a gentle exfoliating serum designed to improve the texture and appearance of the skin. This 30ml formula contains 10% mandelic acid, an alpha-hydroxy acid that is derived from bitter almonds. Mandelic acid is known for its larger molecular size, which allows it to penetrate the skin more slowly and gently than other AHAs, making it suitable for sensitive skin types. This serum also contains hyaluronic acid, which helps to hydrate and plump the skin. With regular use, this serum can help to improve the appearance of uneven skin tone, fine lines, and dullness, leaving the skin looking brighter, smoother, and more radiant. It is recommended for use at night after cleansing and toning, and it is important to wear sunscreen during the day when using this product.
