The study consists in the application of 2 investigational products (one group per investigational product) under normal conditions of use, in adult participants with Atopic Dermatitis.

Probiotics are live micro-organisms which when administered in adequate amounts can exert a health benefit on the host. This health-promoting effects of Lactobacillus reuteri have been extensively studied in the gastrointestinal tract but it is clear that other areas are also interesting for the use of probiotics.

Atopic Dermatitis is a relapsing inflammatory skin disease appearing on persons with a genetic predisposition of allergic pathology. AD generally starts in childhood, however in some cases can continue into adult hood, in at least 10% of cases. AD can effect a persons quality of life and in the chronic stage it can present with dry skin and lichenification.

Research has shown that probiotics have an antimicrobial, anti-inflammatory and barrier function effect, and could therefore be used on subjects with Atopic Dermatitis to relieve and protect.
