Hi pugdog, I have the same problem on the right side of my cheek. I never had any skin problems before except the occasional blemish. All of a sudden I have noticed a "rash" of whiteheads, just on the right side. I faithfully cleanse my face every morning and every night, and I don't wear makeup every day since I am retired. Interesting to find your post, because I have wondered myself how to get rid of them, other than picking and prodding! All of the market products seem to deal with blackheads, not what we are seeking.
Unfortunately I don't have an answer, but if you come up with something, please let me know.
