Undecided Question

Help with dry/acne-prone skin?

My skin is prone to mild acne. However, when I wash my face in the morning it will usually get dry and tight especially on my cheeks. Even if I only wash it once a day. I try to moisturise but it still feels kind of tight. The dryest areas seem to be my cheeks, area of nose between my eyes, the area on the opposite side of my eyes and sometimes my chin.

I still get spots however even in the dry places. I don't understand it. I also use benzol peroxide and oxytetracycline.

Why do I continue to get spots on my dry cheek area because I thought it was because of excess oil/sebum?

What skin products/care routine would you suggest for me?

Thanks
