For decades, fish skin was discarded as waste by the seafood industry, seen as useless after harvesting the edible parts. Today, it’s recognized for its remarkable healing properties, particularly due to its high collagen content — types I and III — which closely resemble human skin in structure and elasticity. This makes it an ideal material for medical applications, especially for burns, chronic wounds, and injuries resistant to conventional treatments.
Properly sterilized fish skin becomes a “second skin,” adhering gently to wounds, protecting against infection, retaining moisture, and promoting tissue regeneration. Patients often experience faster healing, less pain, and reduced scarring. Tilapia skin, in particular, has been successfully used worldwide, including in Brazil, where burn victims saw shorter recovery times and fewer hospital stays.
Beyond its medical benefits, fish skin offers a sustainable solution by repurposing millions of tons of seafood waste each year. Once overlooked, it now exemplifies how nature’s materials, combined with scientific innovation, can restore health, provide hope, and advance sustainability.
