Sun damage, hormone fluctuations, acne scars, and aging can all contribute to dark patches on the skin, also known as hyperpigmentation. Lightness skincare products, on the other hand, are often items that are intended to lighten the skin and increase its general brightness. To address dark spots, try products with vitamin C, AHAs, and retinoids. Furthermore, using exfoliators, hydrating moisturizers, and sunscreen will improve your overall skin radiance and brightness.
