Acne serums deliver concentrated active ingredients directly to affected areas, reducing inflammation and promoting healing. Ingredients like niacinamide or salicylic acid help regulate oil production, minimize post-acne marks, and prevent new breakouts. Incorporating a serum into both morning and evening routines enhances the effectiveness of cleansers and moisturizers. Over time, consistent serum use improves skin tone, texture, and overall clarity, making it essential for acne-prone skin management.
