When should I start using Mederma for skin graft?

Healing process. Skin grafts are two types. Split thickness or full thickness. Split grafts have no dermis, and are typically red for several months. Full grafts first become puffy, and contain dermis . It heals slowly. Medermaa will have little effect on grafts.
Once healed. Once the wound has completely epithelialized and no drainage or scabs are present, it should be safe. Your best bet is to ask your surgeon. He or she can tell you when it's time.

I had a full thickness skin graft on my leg it was slow to heal causing more scaring than expected. Can I use Mederma on it?

Why. If you already bought it ok. If not dont waste your money. Get a silicone pad to cover it and find a way to increase pressure over it with tape or wrapping or a pressure garment. Wear that 24/7 for 3 months until the collagen is mature. Steroid injections are often very helpful as well. Read more...
