When urine comes in contact with the skin frequently, it can alter the PH and cause irritation such as peeling. This is known as incontinence associated dermatitis.
Using water and soap methods can further irritate skin, so you need to use special skincare products designed for incontinence. Using gentle cleansing and moisturizing can help maintain skin integrity and prevent irritation. Let me know if you need any more information or product guidance for this.
To prevent your skin from getting worse, I would definitely book an appointment in with a Doctor or contact the hospital for advice.
