Randomized Controlled Trial Comparative Study Clinical Trial
Novel approach to the treatment of hyperpigmented photodamaged skin: 4% hydroquinone/0.3% retinol versus tretinoin 0.05% emollient cream.
Mild to moderately photodamaged skin is characterized by dyspigmentation, fine wrinkles, and tactile roughness. An optimal approach to the topical treatment of photoaging would simultaneously address all appearance issues. ⋯ Combination therapy of hydroquinone and retinol may improve photoaging-associated hyperpigmentation.
