From your picture, those look like clogged pores / closed comedones.
There are several treatments available to improve and smooth the skin.
I usually combine treatments for this condition so as to achieve as optimal a result as possible.
1) Topicals
I would recommend exfoliating at least once weekly and also topical Isotretinoin so as to remove overlying dead skin/ debris and to increase the turnover of skin cells so as to prevent further build up of sebum/ dead skin cells as much as possible.
2) Orals
Oral medications that can control sebum production should be considered as well as this works from "inside-out" to decrease the production and build up of sebum from within the skin.
3) Machine-based treatment
Lasers such as the Carbon Laser Peel helps to regulate oil production and also removes overlying debris on the skin.
Additionally, we do have a treatment system that removes and extracts clogged areas with medical grade serums and solutions.
Hope this helps.
All the best!
