Hi, thanks for posting your query
Your doctor seems to have given you retenoids for acne
which may cause burning, redness
You may stop using it and apply a steroid
cream like momatosone twice daily for a week . Keep face well hydrated with non comedogenic moisturizer and a mild cleanser .
Once the burning stops you may reintroduce the ointment for lesser time say 2 hours and slowly increase to overnight .
If the burning is severe you may contact your doctor for other alternative .
Hope this solves your query
