Hisamitsu salonpas pain relief patch

Salonpas Pain Relief Patch is a topical pain patch by Hisamitsu designed to temporarily relieve muscle and joint pain such as neck stiffness, shoulder/ backache, sprains, strains, arthritis-related aches and bruises. It uses a transdermal delivery system so the active ingredients act directly where you feel pain without taking pills. 

It typically contains menthol and methyl salicylate, which are analgesic and counter-irritant agents that help ease discomfort and mild inflammation when absorbed through the skin. 

How it works: you clean and dry the affected area, peel off the backing, and apply the patch to the skin. It’s usually worn for up to 8–12 hours, and you should follow label directions on how many patches you can use per day.
