exfoliation and sunscreen

hello! so recently some part of my face has been covered by small whiteheads (its a rare thing for me to have one) and i think its because im using sunscreen that is clogging my pores, so can i have some sunscreen reccomendation that i can use at home (the spf is around 30-35 please, nothing above 40) and will help me with my acne and my acne spots, also i was confused about exfoliation stuff, can someone suggest me what type of exfoliation should i use (chemical, serum, gel, toner, others) for beginner-friendly and reccomend me some products please.

Additionally, any other tips about sunscreen/exfoliation or other(maybe the ingredients i should avoid/i should use, etc) than that is very acceptable, im highly glad if someone give me some

Thankyou so much!!! i gladly appreciate it if someone answer all of my worries
