OTC treatment for burn

Any ideas on what to use for a 2nd degree burn that hasn’t healed very well, that is it is still noticable, over the past 2 months? Looks lame when in a tank-top (on upper arm). Thanks.

The absolute best is emu oil. Will heal it rapidly and with less scarring. Will also help scars disappear

Thanks. Where is emu oil sold? in drugstores?
