The Mandelic Acid 10% + Hyaluronic Acid serum from The Ordinary is a water-based formula designed to provide gentle and effective exfoliation for all skin types. Featuring mandelic acid, an alpha hydroxy acid derived from almonds, this serum utilizes a larger molecular structure compared to other AHAs like glycolic acid, making it suitable for sensitive skin. The inclusion of hyaluronic acid helps to hydrate and smooth the skin surface. This lightweight, non-comedogenic, and fragrance-free serum works to remove dead skin cells, improve skin texture and tone, reduce the appearance of fine lines, and keep pores clear. To use, apply a few drops to clean, dry skin once daily. Users should avoid contact with eyes and apply a sunscreen with SPF 30 or higher during the day. This product is available in a 30 ml size.
