How do you manage acne on the back of your neck?

I have a lot of time with my hair down,

I get acne when I use treatment...

It gets a bit better while my hair is tied up..

So, while selectively doing treatments

We are managing it.

ㅠㅠ But since my hair is on the long side, I really need to use a treatment... Are there any medications or skincare products that might help?

I wonder if even a very light moisturizing lotion gets clogged.

I've been getting acne... ^_^... heh

So on days when I don't apply anything or even use a treatment, haha... it gets all frizzy...

There weren't any great tips for this. Do you have any?
