Oily acne prone skin with sensitivity.

Hello Doc,I have oily acne prone skin with sensitivity to Benzoyl peroxide & irritation to most of the chemical sunscreens.I have felt extreme oiliness during summer (Kerala),I have done Co2 laser resurfacing twice for acne scars on  Sep and Oct 2020.ISDIN FUSION WATER SUNSCREEN for Day time.It suits my skin well without breaking out but this sunscreen costs above 2100 with delivery charge & I can't afford it everytime.Doc,if u don't mind , could u plz suggest an affordable (500-1000 Rs) water based , non comedogenic & broad spectrum physical sunscreen for oily acne prone skin . Due to reapplication it doesn't last longer that's y I can't afford it.I need an affordable sunscreen for indoors as well as outdoors.I hv consulted many dermatologists since last 10 years.but I'm not happy with sunscreens they prescribe as it breaks me out easily and make my skin more oily and irritable.I hv back acne too.i can't affrd azelaic lotion,plz suggest an affrdable cream and body wash for that too.
