The endocannabinoid system of the skin in health and disease: novel perspectives and therapeutic opportunities

“The endocannabinoid system (ECS) and the skin. Recent studies have intriguingly suggested the existence of a functional ECS in the skin and implicated it in various biological processes. It seems that the main physiological function of the cutaneous ECS is to constitutively control the proper and well-balanced proliferation, differentiation and survival, as well as immune competence and/or tolerance, of skin cells. The disruption of this delicate balance might facilitate the development of multiple pathological conditions and diseases of the skin (e.g. acne, seborrhea, allergic dermatitis, itch and pain, psoriasis, hair growth disorders, systemic sclerosis and cancer).

Perspectives in the ECS-targeted management of skin diseases

… preclinical data encourage one to systematically explore whether ECS-modulating drugs can be exploited in the management of common skin disorders…

 … we review preliminary data and discuss the possible applications of ECS-targeted therapies…ECS-targeted approaches in skin diseases. Modulations of the fine-tuned tone of the cutaneous endocannabinoid system (ECS) could have therapeutic values in the management of a large variety of human skin diseases…

Conclusions and future directions in experimental and clinical research

… it is envisaged (this is also strongly supported by pilot studies) that the targeted manipulation of the ECS might be beneficial in a multitude of human skin diseases. However, to predict the real therapeutic potential and translate the exciting preclinical observations discussed earlier into clinical practice, numerous important questions should carefully be addressed. Nevertheless, targeting the cutaneous ECS for therapeutic gain remains an intriguing and provocative possibility warranting future studies.”
