hi..thanks for your query.
The treatment for scars
depend on the nature, depth and extent of the injury
and the scarring process.Depending on the same, there are several treatment options ranging from creams to surgical methods.
If the result of burns are only darker skin on smaller surface areas, topical depigmenting creams may be applied to achieve a lighter colour. Topical self drying silicone gel and topical silicone gel sheetings are safe and effective treatments for hypertrophic and keloidal scars. It is easy to apply and cosmetically acceptable.burns leading to contractures
over a larger area are best treated by skin grafting
from a normal region of the body.
You should visit a plastic surgeon to assess the nature and degree of scarring as the exact modality can only be suggested on inspecting the area .
hope this helps.take care!
