Hydroquinone is a topical depigmenting agent that inhibits tyrosinase, reducing melanin production. It is used to treat hyperpigmentation conditions such as melasma, post-inflammatory hyperpigmentation, and dark spots.
Vitamin C (ascorbic acid and its derivatives) is a topical antioxidant that neutralizes free radicals, supports collagen synthesis, and helps reduce hyperpigmentation for a more even skin tone. It is commonly used in serums for photoprotection support and anti-aging benefits.
