I have only been getting cysts on my neck over the past few months. What's weird is that 2 years ago, when the acne on my face was at it's worst (it was vile) I didn't have a single spot on my neck. Now I have them across my jawline and coming past my ear.

I think stress from exams may have caused them except they're still here 2 months after finishing...so when did everyone else develop neck acne and what do you think was the cause?

I have no clue but that has been happening to me too. Used to never get a single mark on my neck but now they are all over my jawline and crawling towards my chin. Now I have an acne beard. Which is worse because I'm a girl

This only started about a month ago. In fact now that I think about it, it was during a summer class that I took. Maybe stress really is the cause of it.

It started developing about a year ago after I turned 17. It slowly got to the point where the right side of my neck was full of cysts and the skin had so many large dark areas of blood pooled under the surface. Since I started this new regimen, my neck has started healing. I still get some pimples, but the big ones have gone away. The skin is still discolored, but it's slowly getting better everyday.

Edit: It was worst at the midsection lateral sides of my neck. Jawline was pretty bad, but it was worse right below that.

After stopping the Yasmin pill. Only just now started to subside a bit after many months.
