The skin’s comfort zone is regulated by the pain receptor TRPV1, which is expressed in the epidermis’ sensory neurons and keratinocytes. Elevated levels may lead to increased skin sensitivity; moreover, heat stress caused by IR-light can activate TRPV1, thereby inducing collagen degradation in a process known as thermal ageing.
Defensil-Soft, which will be launched by Rahn Group at in-cosmetics 2017, is described as a neuro-balm that blocks TRPV1, reducing skin discomfort and irritation within minutes while preventing IR-ageing. Based on the mushroom Albatrellus ovinus, also called the Northern truffle, the ingredient conforms to COSMOS and Ecocert.
An interesting benefit of Defensil-Soft is its function in improving the skin’s tolerance towards certain irritants in cosmetic formulations.
