Jessner skin peel for closed comedones
From the photos presented, it looks as though you have mild closed comdeonal acne meaning they will not come to the surface easily like traditional blackheads and whiteheads. This type of acne is more difficult to treat. You should avoid squeezing these 'under the skin' types of spots as there's a chance you could make them irritated and inflamed. Squeezing could also spread the bacteria causing more spots and potentially an infection and scarring. I recommend a salicylic acid or jessner skin peel which will prevent the build up of more spots and loosen the dead skin cells to. In addition, you may benefit from Isolaz: the three step system utilises a laser treatment to help kill the bacteria and also deeply cleanses your pores to remove impurities and dislodge trapped dead skin cells.
