We recommend using face serums that contain active ingredients such as Salicylic Acid, Niacinamide, Retinol, Hyaluronic Acid, etc. They would help maintain the skin's sebum and pH levels, and would thus be very effective on acne-prone skin. You should also check if such a serum features natural extracts and a toxin-free composition. Ascertaining this would help ensure better results over time. We recommend using Mamaearth best serum for acne prone skin which is Skin Correct Face Serum with Niacinamide and Ginger Extract to prevent acne marks. This gentle formulation reduces acne marks, dark spots, and blemishes. It also stimulates melanin activity and evens patchy skin, giving you youthful skin.
