Detailed answer

To brighten dull skin, follow these steps: 1. Exfoliate regularly: Exfoliation helps remove dead skin cells that can contribute to dullness. Use a gentle chemical exfoliant like glycolic acid or salicylic acid to reveal brighter skin. 2. Use vitamin C serums: Vitamin C is a powerful antioxidant that can help brighten the skin and reduce hyperpigmentation. Look for serums with a high concentration of pure vitamin C to achieve the best results. 3. Incorporate brightening ingredients: Niacinamide and kojic acid are effective ingredients for brightening dull skin. Niacinamide helps improve skin texture and reduce discoloration, while kojic acid targets hyperpigmentation. 4. Protect your skin from sun damage: Exposure to the sun's UV rays can worsen dullness and discoloration. Always apply a broad-spectrum sunscreen with SPF 30 or higher to protect your skin from sun damage and maintain a brighter complexion. Remember, consistency is key when it comes to brightening dull skin. Incorporate these steps into your skincare routine and be patient as it may take time to see visible results.
