I keep getting hard, painful acne around my chin.

Strangely, the rest of my body is fine, but I am worried because I repeatedly get acne only around my chin. At first, they pop up like small pimples, but as time passes, they swell up and turn red, and some of them are painful to the touch. Just when I think one or two are going away, another one appears in a different spot, so my skin never gets a chance to clear up.

Especially on my chin, red marks or dark spots seem to linger for a long time even after the acne subsides. I try not to squeeze them with my hands and wash my face thoroughly, but managing them isn't as easy as I thought.

Is the treatment for chin acne different from acne on other areas because it is significantly influenced by hormones? At dermatology clinics, in addition to extraction or anti-inflammatory injections...
