Abstract

A comfortable and fitting corn patch comprises: a waterproof membrane, a thin film made of thermoplastic polyurethane, with a smooth waterproof surface on the upper surface and an adhesive surface on the lower surface; a hydrogel dressing layer, a solid gel composed of salicylic acid, lactic acid, saponins, and croton oil, placed below the waterproof membrane and attached to the adhesive surface, and pressed downwards from the center of the waterproof membrane to form a concave surface on the upper surface, while the area of ​​the waterproof membrane other than the concave surface forms a plurality of raised dots, thereby forming a thin sheet-like corn patch; and a release sheet for adhering the thin sheet-like corn patch to its surface. In use, the thin sheet-like corn patch is peeled off from the release sheet, and the concave surface is aligned with the user's corn to be treated, allowing the thin sheet-like corn patch to adhere to the user's skin, with the concave surface lifting upwards and covering the area around the corn to be treated. This invention improves the comfort and fit of the patch, making it less prone to falling off.
