Considering that your burn was more than a week ago, the best thing to do is to use ointment or gel to keep the area as moist as possible. Good choices include Vaseline, Aloe Vera, cocoa butter and specialized creams such as Cicaplast by Laroche-Posay. The important thing here is to keep the skin moist to prevent slow healing which increases the risk of scarring. Additionally, massage your skin quickly to soften it and avoid the creation of rigid scar tissue. We look forward to seeing you.
