Itch-Relieving Cosmetics

This review aims to explore the evolving role of cosmetics in alleviating itch, transcending their traditional aesthetic function. With a focus on formulations enriched with natural oils and other bioactive components, we examine the efficacy and safety of various cosmetic ingredients designed to control itch. Highlighted are ingredients such as colloidal oatmeal, postbiotics, menthol, peppermint, cryosim-1, capsaicin, asivatrep, polidocanol, pramoxine hydrocholoride, and palmitoylethanolamide, which are recognized to reduce itch. Special attention is also given to phytochemicals that can modulate the Janus kinase/signal transducer and activator of transcription signaling pathway and carry the potential as an itch-relieving cosmetic ingredient. This review encompasses clinical studies that verify the itch relieving effect of these cosmetic ingredients. By integrating current scientific evidence, we aim to shed light on the potential of anti-itch cosmetics as an adjunct to standard itch treatment, thereby broadening our understanding of their role in dermatological care.
