a heterogeneous group of biologic, synthetic, or biosynthetic materials that can provide temporary or permanent coverage of open skin wounds

made of both layers of the skin (dermal and epidermal), ideally mimicking natural tissue

produced by bioengineering different types of skin cells
. Some are made using a patient’s own skin cells, tissue from donated cadavers, animal tissue cells, or a combination of these. How they work is dependent on the skin function they are attempting to replace.
What is a synthetic skin substitute?
Synthetic skin substitutes are
constructed out of non-biological molecules and polymers that are not present in normal skin
. [8] These constructs should be stable, biodegradable and provide an adequate environment for the regeneration of tissue.
How long does a synthetic skin graft take to heal?
The donor area of partial thickness skin grafts usually takes about 2 weeks
to heal. For full thickness skin grafts, the donor area only takes about 5 to 10 days to heal, because it’s usually quite small and closed with stitches.
