11 Dark Spots Treatment Options Explained

2. Kojic Acid

Kojic acid is a natural compound made during fermentation that slows melanin production by inhibiting tyrosinase. Many dermatologists suggest it as an alternative for people who want plant-derived options. You’ll find kojic acid in serums and creams aimed at reducing sun spots and post-acne marks. Its effects are gentler than prescription hydroquinone, so it can be suitable for long-term use when tolerated. Some users notice lightening within six to eight weeks, depending on concentration and consistent use. Sensitive skin types should patch-test first because kojic acid can cause irritation or contact allergy in a minority of people. In Indian skin-care practice, kojic-containing formulas often sit alongside traditional brightening ingredients like turmeric; keep expectations realistic about timelines when combining methods. For best results, use kojic acid at night and protect skin with a broad-spectrum sunscreen every morning to prevent the treated spots from darkening again.
