Itching and symptoms visibility can have a significant impact on quality of life. This is the case when eyelids are affected. Therefore, we evaluated a dermo-cosmetic product designed to care AD on eyelids.Subjects and Methods: An initial analysis of the product included 20 healthy women with no AD signs. A clinical evaluation of the effect of the product on AD sign severity was performed on 33 subjects presenting AD symptoms on eyelids. We also analyzed the product’s capacity to prevent relapses in a parallel group clinical evaluation performed on 66 subjects.Results: First, on the forearm skin of healthy subjects, the product reduces erythema and decreases transepidermal water loss when used for 28 days. Second, when clinically evaluated on subjects with eyelid symptoms undergoing a corticoid treatment, the product leads to reduced AD signs scored by a dermatologist, better self-evaluation of symptoms by subjects, and improved quality of life. Besides, upon assessment in a randomized controlled clinical evaluation with subjects prone to AD relapses but without symptoms, the product also drastically reduces relapse frequency. If erythema reduction is the only sign identified by a dermatologist, the product greatly and rapidly improves the quality of life of subjects.Conclusion: These effects can be explained by the known actions of the product’s ingredients. Rich in hydrating compounds, fatty acids and anti-inflammatory compounds, it aims at maintaining and restoring the epidermis structure and function to preserve it from irritants. It effectively shows that a daily care and hygiene routine with a dermo-cosmetic product designed according to an ecobiological approach leads to objective improvement of AD and subjective perception of quality of life.Keywords: atopic dermatitis, eyelid, dermo-cosmetic, relapse, ecobiology
