Suitable Sunscreen for the below case.

Hello experts, Please suggest a sunscreen looking at the case.  Case history: I was on treatment for acne starting 12 dec 2022. I was prescribed epiduo gel and was asked to apply in the evening for 2 hrs. I wrongly used the cream around my eye and mouth, thinking the redness is the common effect of epiduo I did not took it seriously.  Later after one week I got a rash near my mouth and skin turned dark.   Also my skin at the Side of forehead near eye became dark. So it was somewhat a dark patch like situation on my face.  I had to go out for work on 6/1/23 which lead to sun exposure and the dark skin at the side of the forehead near left eye turned into blister and peeled. I rushed to the doctor to which he asked me to stop epiduo and prescribed medrol 4 mg for 7 days, Cetaphil dam lotion and calosoft Af.  As of today the dark skin patch are faded a bit but around the mouth and eyes visible skin discoloration and scars are there. Also I got pimples on my forehead and nose.
