Atopic dermatitis is a chronic inflammatory skin disease characterized by flare-ups of inflamed, dry, and itchy skin affecting over 200 million people worldwide. “Emollients plus” containing active cosmetic ingredients such as herbal extracts and phytochemicals have the potential to surpass the efficacy of conventional emollients, while avoiding side effects associated with pharmacological interventions. The reported 12-week clinical trial (NCT05790083) evaluated long-term efficacy and tolerability of oil-in-water emulsions BNO 3731 and BNO 3732 containing ginger extract and cannabidiol as basic emollient therapy for atopic dermatitis. A total of 100 adults and children with a history of atopic dermatitis were included and applied BNO 3732 (body lotion) twice daily and BNO 3731 (intensive care product) as needed. Over 12 weeks the emollients plus combination led to sustained improvement of peak pruritus and patient-reported outcome measures, i.e., “Recap of atopic eczema”. Objective dermatological evaluation showed progressive improvements for vIGA-ADTM and isolated symptoms, i.e., erythema and dryness. Instrumental analysis of intercellular lipid contents and lipid lamellae organization in the stratum corneum demonstrated recovery of the epidermal barrier integrity. The clinical results provide evidence on the efficacy of herbal emollients plus beyond mere moisturizing and occlusive properties. BNO 3731 and BNO 3732 were very well tolerated.
