This is Dr. Rahul Nagar from New Delhi, India.
I am a consultant dermatologist
Yes it is a chemical burn
With time and proper medications it would clear.
If treated correctly, there shouldn't be any scars
. Any scars would be temporary.
It may take 1-6 months to heal.
Apply flutibact cream for 7-10 days, twica daily and later apply melalong cream at night and sunscreen with a SPF30 during daytime.
Get well soon.
