Hydrogel pain relief patches are cooling analgesic products. Unlike regular plasters, hydrogel pain relief patches provide a cooling effect, making them suitable for sudden relief of strains, sprains, and pain caused by unexpected situations.
The gel layer of the hydrogel pain relief patch contains a large amount of volatile substances such as water and alcohols, as well as essential analgesic drug ingredients. These active ingredients can penetrate the skin's pores to reach the affected area, providing pain relief. Furthermore, the significant amount of water evaporation removes heat, providing a cooling effect while also reducing swelling.
