Evaluation of the Effect of Combined Use of Cosmetic Products for Dry and Itchy Skin.

Confirmation in Human Subjects of a Cosmetic Product Efficacy After Application in the Body Under Normal Conditions of Use.

The goal of this study is to learn if combined use of shower oleogel and body lotion works to improve skin itching and dryness in adults. It will also learn about its safety. The main question it aims to answer is:

• Does the products use improves skin hydration and itching? Researchers will compare shower oleogel and body lotion to a commercially available shower gel and the body lotion to see if the combined use is more efficient than use of body lotion alone.

• Use assigned products every day for 1 month
