I have suffered from spotty face skin for 20 years! From
experience I find rubbing a (clean) piping, hot wet flannel over your
face after washing (with soap and water) helps. The flannel's heat
opens up the pores and the roughness of the flannel unblocks the pores
and knocks any white heads off. This stops you from having to use your
hands to squeeze your spots and spreading the problem further.
I use this method of washing morning and night, and my acne is reduced and under control.
