Skin care for acne prone/sensitive skin?

I am 25 years old, recently came off my birth control pill and I look like I did in middle school. My face is covered in zits. It gets worse around my period but there is NEVER a day where I have less than 4 pimples, regardless of my cycle. I've watch about a thousand youtube videos and been to the dermatologist. Nothing works. Any tips for skincare with acne prone skin? What has worked for you?

I drink 2-3liters of water per day and wash my pillow cases every week! Currently I'm trying different products but I have always used cetaphil cleanser and moisturizer. The only time I had clear skin in my life was while on BC + spironolactone, so I'm almost 100% sure something is off with my hormones. But dermatologists dont care about the cause they just want to treat the symptoms by slathering chemicals on my face that cause dryness and irritation which give me more breakouts. Idk what to do, I'm so fed up and worried I'll have acne into my 30s 😞😖😢
