Background In patients with psoriasis, the non‐lesional skin also presents abnormalities, requiring emollient application on the whole body. Objectives To evaluate the tolerance of a new emollient balm containing celastrol, an active ingredient with anti‐Th17 immunomodulatory properties used alone or in association with topical or systemic drug treatments or phototherapy, and its efficacy when used alone. Methods Adults with body plaque psoriasis applied the product over the whole body once a day for 4 weeks (balm used alone in 41 patients and with ongoing treatment in 50 patients). At D1, D8 (‘balm alone’ study) or D15 (‘balm in association’ study) and D29, the dermatologist rated physical and functional signs and assessed pruritus and body global lesion score (evaluating erythema, induration/thickness, scaling and dryness) in the ‘balm alone’ study. Results No reaction related to the product was reported, and the tolerance was deemed excellent. In the ‘balm alone’ study, mean pruritus intensity score significantly decreased at D8 (−39%, P < 0.001) and D29 (−60%, P < 0.001) compared with D1, together with the body global lesion score (−24% at D8 and −26% at D29, P < 0.001). In parallel, quality of life improved, as evidenced by a patient‐reported outcome questionnaire. Cosmetic acceptability was good. Conclusion This new emollient balm was very well tolerated by patients with body plaque psoriasis either alone or in association with drug treatment or phototherapy, which is important to ensure long‐term compliance. Daily application during one month improved pruritus, physical signs and quality of life.
