This modern wound care device consists of two layers-the upper layer mimics the epidermis and the layer underneath is a porous matrix which replaces the dermis. The top temporary epidermis is made of silicone which provide immediate physiological closure preventing fluid and heat loss along with functioning as a bacterial barrier. The underlying matrix layer consists of cross-linked
