If you want the full package:
Oil Cleanser
Foaming Cleanser (one with salicylic(?) acid will help prevent sebaceous filaments (the stuff in your nose that people call blackheads and shit))
Toner
Serum (Ampoules, retinol, niacinamide etc. Make sure not to apply too many products as it may damage your skin instead of rejuvenate it. For many, "TheOrdinary Niacinamide+Zinc" is pretty good.)
Moisturizer
Suncream/Sunscreen
Once or twice a week apply a clay pore mask pack after cleansing.
Sleep regularly, stay hydrated, and stay away from oily/unhealthy foods. You need to be consistent with skincare - twice a day and after a few months you'll notice changes. With niacinamide you may notice changes within weeks tbh.
