Hi,
Burn injury. as with all other forms of skin injury, will heal best under optimum wound healing conditions to minimize the risk of scarring. This usually means that the healing environment must be clean and moisture-controlled. Careful attention to wound cleansing and the use of a silver-based antiseptic cream/ointment or silver impregnated non-stick dressings are recommended.
Scarring may occur if the wound is deep or if it gets infected.
The red patch will generally take several months to gradually fade.
Hope this helps!
