11 Dark Spots Treatment Options Explained

6. Azelaic Acid and Niacinamide: Gentle, Effective OTC Options

Azelaic acid reduces pigment and calms inflammation, making it helpful for acne-related dark marks and melasma. It’s commonly prescribed in 15–20% formulations or available over the counter at lower strengths. Niacinamide supports barrier function and reduces pigment transfer from melanocytes to skin cells, so combining these two can improve tone while minimizing irritation. Both ingredients are usually well tolerated across skin tones, which helps lower the risk of post-treatment darkening. You’ll often see steady improvement over two to three months with daily use. Apply azelaic acid in the evening and niacinamide in the morning if your routine includes a vitamin C serum. These actives fit well into Indian daily schedules because they’re compatible with humid climates and can be layered under light, non-greasy sunscreens.
