From the photo, you appear to have large whiteheads (macrocomedones).
Macrocomedones are generally difficult to treat and clear. Treatment options include topical retinoids, chemical peeling, light electrocautery, low dose isotretinoin over 12-18 months. Avoid greasy make-up/sunscreens that may aggravate the condition.
Do see your preferred aesthetic doctor for a thorough close-up assessment of your condition and discussion on the best treatment options highlighted above.
Hope this helps!
