Studies on the formulation and functionality of an innovative line of topical products for atopic skin

Abstract

Dermocosmetics are products intended for sensitive and problematic skin. They are a good solution for additional care of skin affected by conditions such as atopic dermatitis, acne, psoriasis, or for couperose skin. The compounds of particular importance in the care of atopic skin include ceramides, ectoine, hyaluronic acid, vitamins A and E, as well as natural vegetable oils. The aim of this work was to develop a qualitative and quantitative approach and to investigate the characteristics of formulations such as a face cream, a topical cream, a body lotion, and a cleansing foam, dedicated to patients with atopic dermatitis. The newly developed cosmetic formulations showed good physical and chemical characteristics, typical of this type of product. They were also structurally and microbiologically stable during storage at various temperatures. Dermatological tests did not reveal any irritating or allergenic properties. The best data were obtained for the face cream, namely improvement of skin hydration by 21.88%, reduction of transepidermal water loss by 15.86%, alleviation of erythema by 15.77%, and of skin sensitivity by 17.20%. This work resulted in the preparation of innovative dermocosmetics to be used for atopic skin. The cosmetics have a unique composition and delicate formula, show high biofunctionality, and meet all the requirements for cosmetic products intended for marketing.
