What can you do to prevent burn wounds from leaving scars?

Question

My mom was baking last weekend and burned her arm pretty bad. The skill swelled up then burst open and tore off now she has 2 open cuts. She wants to know if there's anything she can do to prevent scarring after the wounds heal?

Answer 1

Mederma 3-4 times a day for until the scar fades mostly away.  I think it's around 8 weeks for new scars that are treated promptly, and 3-6 months for old scars.

Answer 2

Miderma and vitamin E ointment
