Corns are usually treated with a cornsore patch, which is considered good when the cornsore is applied until it is completely softened and the keratin plugs below the stratum corneum are completely removed. The main ingredient of the patch is salicylic acid, which is strongly corrosive and can corrode the tissues and muscles of the corneal area. Before the treatment of corns, you should first clean and soak the corns area, and after the corns cuticle is softened, the surface hard skin will be removed, and then the corns patch will be applied to the corns. After applying the medication, the skin of the affected area will be reduced to the touch and the color will change to white, and the corneal tissue will fall off with the white skin after continued use. The cornsite patch needs to be replaced diligently as prescribed by the doctor. Each time it is replaced, it needs to be cleaned, softened and cleared of the cuticle to ensure that the patch is aligned with the cornsite area so that the cornsite plugs are safely shed thus achieving the purpose of eliminating cornsite. When using corns, salicylic acid may corrode the surrounding normal skin tissue, so the corns patch needs to be operated under the guidance of a doctor. Depending on the severity of the corns, the duration of use of the patch for corns varies. Intermittent use during the use of corns eye patch may lead to recurrence of corns eye and poorer treatment results. After corns eye patch treatment, most of the corns will gradually fall off. When the effect of corns eye patch treatment is not satisfactory, you can go to the hospital for physical therapy or surgical removal.
