Tilapia skin is a frugal and effective option to treat patients with second- and third-degree burns. This fish skin contains large amounts of moisture and type I collagen proteins at levels comparable to human skin. This prevents scarring while promoting the healing of wounds. The tilapia skin is processed and sterilized, and it has been successfully used as bandages to treat patients with second-degree burn wounds. It cuts down healing time by up to several days and reduces the use of pain medication. Tilapia skin is more resistant than pig skin, rendering it a better option and also withstands mechanical stress, such as stretching. It has been shown to be as good as human donor skin. The cost of the treatment is reduced by more than 60%, as it costs 75 cents less than traditional bandages per application.
