Blackheads

Blackheads, otherwise known as comedonal acne, are caused by plugging of the pores.  In order to unplug the pores and prevent this from occurring, dermatologists often prescribe a group of medications called retinoids.  These are usually applied in a small amount at bedtime and are excellent at clearing the comedones.
