Thanks for the query.
It is a Superficial burn that you had. The degree of burn is negligible.
Your burn scar is healing well, that is why it is Pink in colour.
Your skin should become normal by 2 weeks or 3 weeks at the most.
By 6 months, your skin will be perfectly fine with also no scars
All Facial injuries
heal extremely well since the blood supply in face in extensive and very rich.
Do not worry.
Wishing you early recovery.
