Evaluating Topical Imipramine and Amitriptyline for Rosacea Redness

This study is looking at whether topical (applied to the skin) imipramine or amitriptyline can reduce redness caused by ultraviolet B light in people with rosacea. Rosacea is a common skin condition that causes easy blushing and facial redness, often made worse by sunlight. Researchers will compare how well 4% imipramine and 4% amitriptyline reduce redness compared to a vehicle (a cream or liquid without active medicine). They will measure redness at 10, 60, and 120 minutes after treatment. You may be able to join if you are an adult with rosacea or a control subject without a history of flushing/blushing, and have Fitzpatrick Skin Type I-IIII. The study aims to enroll 48 participants, but its current recruitment status is unclear.
