What this trial studies

Participants with facial hyperpigmentation types such as melasma, solar lentigines, or post-inflammatory hyperpigmentation will use either untinted or tinted sunscreen for 8 weeks. The study aims to see if regular sunscreen use improves the appearance of dark spots under normal daily conditions. It is an interventional, single-sunscreen comparison without a separate control group. Eligibility includes adults across a range of skin types who have visible facial hyperpigmentation and can follow study procedures. Safety and tolerability will also be monitored.
