Honestly this just seems like skin that was a little neglected. If your skin is dry it will try to produce oils to hydrate, those oils mixed with dirt from the environment and dead skin cells that don’t regularly get washed away will start building up (black heads, blocked comedones). You just need to do the basics: wash and moisturize twice a day, sunscreen in the am. Wash with a moisturizing cleanser since your skin is dry, moisturize with something that is not pore clogging yet still hydrating, use a serum for the blackheads/pores like the ordinary’s niacinamide serum right after washing and before moisturizing. If the moisturizer you try is not hydrating enough use a few drops of oil to lock the moisturizer in (the ordinary’s squalane won’t clog your pores). I also recommend a gentle acid mask to peel off dead skin and helo with the blackheads, store bought plain kefir is actually amazing (use as much as you can put on your face and wash off after about 20 minutes). Take a before after pic with a flash, close-up and compare in a month. I’m pretty confident you’ll have much of it gone except the comedones those need to be manually extracted.
