A high-emollient liquid cleanser for very dry and atopic-prone skin: Results of an in-use tolerance and efficacy study conducted under dermatological, pediatric, and ophthalmological supervision.

Background: Emollients play a key role in the treatment of eczematous lesions and xerosis such as in atopic dermatitis. However, studies that show the actual benefits of cleansers are few and far between.

Aims: This study aims to evaluate the tolerance and efficacy of a high-emollient liquid cleanser (HELC) designed for very dry and atopic-prone skin, in the absence of any additional skin care. The product is a soap-free and fragrance-free liquid cleanser, containing mild surfactants and a ternary system of selected emollients: glycerin, vaseline, and paraffin.

Methods: In-use study was conducted under dermatological, pediatric, and ophthalmological supervision in 50 subjects (infants, children, and adults) with "dry to very dry and atopic-prone" skin. The primary objective of this monocentric, open, and intra-individual study was to assess the dermatological and ophthalmological tolerance of HELC after 21 days of using it at least once a day on the face and body. The secondary objectives were to evaluate its efficacy based on a clinical score (SCORAD), assess its short- and long-term moisturizing effect by measuring hydration rates (Corneometer ), and ascertain its cosmetic acceptability through a subjective evaluation questionnaire.

Results: The study validates the good dermatological and ophthalmological tolerance of HELC. Its efficacy was demonstrated by improvements in the SCORAD and moisturizing scores. Furthermore, the product was very well accepted by the subjects.

Conclusion: The fragrance-free HELC tested in this study for 21 days on "dry to very dry and atopic-prone skin" improves skin dryness and pruritus while ensuring good tolerance.
