Official title
A Single-Blind Study to Assess Benefits of a Controlled Daily Skin Care Regimen on Retinoid Intolerant Patients (Derm 570)
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Sun-damaged skin, caused by chronic exposure to ultraviolet (UV) light, is characterized by features such as wrinkling, uneven skin color, roughness and brown spots. An effective treatment for sun-damage that is commonly prescribed is topical retinoic acid (RA). However, the major drawback of topical RA use has been frequently observed irritation characterized by redness, dry skin and severe itching. In this study, we examine whether a daily skin care regimen comprised of an ultra mild cleanser and an effective moisturizer can help improve tolerance to RA treatment.
