hi, I have a white/ skin colored pimple that just formed on my cheek a few weeks ago. I was on Accutane and just got off in the middle of june. I've also been in the sun quite often and went on a cruise in the carribean . There's also a black dot in the middle. Now it doesn't look like a blck head because black heads are usually small and don't get to the size tht this is and I never really got black heads often even before Accutane. But would you be able to guess what it is by the description?should I get in touch with my dermatogologist or just let it go because it's just one pimple? ive had a few here and there but I just let them go because there usually so small you cant see them hardly at all.
