title: Effects of a new topical combination on sensitive skin.
abstract: Using well-tolerated cosmetics or those with soothing effects is recommended to treat sensitive skin. However, we lack clinical studies. Two clinical trials were performed on sensitive skin in France and Thailand. The primary objective was to evaluate the preventive soothing effect. The secondary objectives were to evaluate the immediate soothing effect, product tolerance, and impact on quality of life. Evaluation methods included a stinging test and scoring erythema and stinging intensity. We also assessed tolerance, quality of life using the Dermatology Life Quality Index, and cosmetic qualities. The clinical trials were performed in France and Thailand to test efficacy in two different environments and on different ethnic skin. Interesting effects were observed in patients with sensitive skin in France and Thailand: a preventive soothing effect, a soothing effect on erythema, and an immediate soothing effect. In vivo biometrological, sodium lauryl sulfate, and capsaicin tests confirmed these data. A favorable effect on quality of life was also noted. The product was appreciated by volunteers for its efficacy, tolerance, and cosmetic qualities. A preliminary study on the effects on interleukin 8 was also included in the paper.
