Most of the bumps on your picture appear to be little keratotic growths of the skin.
These are indeed effectively removed by lasers which can carefully singe them off. Other growths, such as sebaceous hyperplasia, syringomas, milia seeds, etc can also be effectively removed with the appropriate lasers.
These growths aren't caused by clogged pores; they're usually due to age, UV exposure, or just regular overgrowth of certain components of the skin.
Exfoliation and acidic toners/retins can help to reduce the occurrence of these growths but will not get rid of the existing ones.
