What it is
"Skin substitutes" is a broad term for products applied to wounds as a covering or scaffold. Some are made from human tissue, some from animal tissue, some from lab-made materials, and some combine more than one of these. They are not all the same, and they are regulated in different ways.
Some skin substitutes are made from amniotic membrane, the thin tissue that surrounds a baby in the womb. Amniotic membrane used as a wound covering is an established use. Products are usually processed, and most do not contain living stem cells after processing.
Because the category is so wide, the details matter: what the product is made of, where the tissue came from, how it is regulated, and what wound it was designed for. Some products are cleared or approved as medical devices, while others are regulated differently. A licensed clinician can explain which applies to a specific product.
How it’s traditionally been approached
Wound care has long started with the basics: cleaning the wound, removing tissue that is not healthy, protecting it with dressings, managing swelling or pressure, and looking at factors like circulation, blood sugar and nutrition. These steps are often the foundation of care.
Skin substitutes have generally been considered for certain hard-to-heal wounds, such as some foot ulcers, pressure injuries, venous leg ulcers, or burns, often after standard care has been tried. Whether one is appropriate depends on the wound and the person.
Approaches vary between clinics and between individuals. Some people heal well with standard dressings and offloading, while others may be offered an advanced product. Neither path is right for everyone, and decisions are made between a patient and a licensed clinician after an evaluation.
How the right doctor may help
A wound care specialist or podiatrist may begin by asking about your health history, medications, how long the wound has been present, and what has been tried so far. They may examine the wound, check circulation and sensation, and look at things that slow healing, such as pressure on a foot.
A provider may then explain whether a skin substitute is something they would consider, or whether other steps come first. Only a licensed clinician can decide what is appropriate for you after an evaluation, and there are no guarantees about how a wound will respond.
Useful questions to ask: What is this product made of, and what is the tissue source? What is its FDA status for my type of wound? What are the risks and the alternatives? What would the total cost be, and does my insurance cover it? How will we know if it is helping, and what happens if it is not?
The whole-person view
Healing involves the whole person. Long-lasting wounds can bring pain, worry, sleep trouble and frustration, and stress can in turn affect how well the body feels and copes. Blood sugar, movement, nutrition and rest also play a part, so many people find a whole-person view helpful.
Some people explore body-based support such as Somatic Experiences to help with stress and tension while they recover. Others find talk therapy through Therapists.plus useful for coping with the emotional side of a slow-healing wound. These are complements to medical care, not replacements for it.

Keep in mind
- Licensed professionals should guide care for any wound, especially if you have diabetes, poor circulation or signs of infection.
- Amniotic membrane as a wound covering is an established use, but injectable amniotic, umbilical cord, Wharton's jelly and exosome products for joints, pain, hair, skin or "regeneration" are generally not FDA-approved for those uses, and the FDA has warned the public about unapproved regenerative products.
- Not every skin substitute is the same, so ask any provider about FDA status, tissue source, risks, alternatives and total cost, and check your insurance before treatment.
- For emergencies such as spreading redness, fever, heavy bleeding or severe pain, call 911. If you are in emotional crisis, call or text 988.

Frequently asked questions
What are skin substitutes for wounds?
Skin substitutes for wounds are materials, made from human tissue, animal tissue, lab-made components or a mix, that are placed on a wound to cover and protect it while the body heals. They are not all alike. A licensed clinician can explain which type, if any, may fit your situation.
Are amniotic skin substitutes FDA-approved?
It depends on the product and its use. Amniotic membrane used as a wound covering is an established use, but regulatory status varies by product. Injectable amniotic products for joints, pain or "regeneration" are generally not FDA-approved for those uses, so ask your provider about the specific product's status.
Do skin substitutes contain stem cells?
Most amniotic-based products contain no living stem cells after processing, and they should not be described as stem-cell treatments. Ask your provider exactly what the product contains and how it was processed.
Who applies skin substitutes for wounds?
They are typically applied by licensed clinicians such as wound care physicians, podiatrists or other trained providers. Availability depends on the clinic and the type of wound. You can ask about a provider's training and experience with these products.
Will a skin substitute heal my wound?
There is no guarantee. A skin substitute may help support healing for some wounds, but results vary with the wound, overall health, circulation and other factors. A provider can discuss realistic expectations after an evaluation.
Does insurance cover skin substitutes for wounds?
Coverage varies by plan, product and wound type, so check with your insurer before treatment. Ask the provider's office for the total expected cost and what documentation your plan may require.
