18724 Tolerance and subject satisfaction of an over the counter colloidal oatmeal (Avena sativa) lotion in patients with psoriasis and sensitive skin

      Psoriasis is an autoimmune skin disease that is associated with significant impairment in quality of life including skin discomfort and dissatisfaction of skin appearance. The purpose of this study was to determine the tolerability and satisfaction in skin appearance of a 1% colloidal oatmeal lotion on individuals with psoriasis. Sixty women with psoriasis and self-reported sensitive skin were enrolled into the study. Subjects applied only the assigned 1% colloidal oatmeal lotion to their entire body at least once per day for 4 weeks. Subjects assessed their skin condition on a 100-point VAS and completed product-satisfaction and Quality of life questionnaires at baseline and after 4 weeks of use. After 4 weeks of application, subjects perceived a significant improvement in each of the skin parameters queried including dryness, desquamation, roughness, smoothness, softness, suppleness, redness, discomfort, and itching with an average of 38% improvement over all the parameters. The greatest improvements included itch and desquamation with a 45% improvement over baseline scores for both. More than 96% of subjects thought the product helped to reduce both the severity and number of patches on the body. In addition, 100% of subjects felt the product was suitable to use daily for their skin type. The product was well tolerated and no product related skin adverse events were reported during the study. In conclusion, the over-the-counter colloidal oatmeal moisturizing lotion improves the skin appearance and discomfort associated with psoriasis and is a suitable adjunctive moisturizer for daily skincare in this patient population.
