Homeopathy for Chin Problems

Hi friends,

I write to you asking advice on a skin problem I have. For about three years now, the skin on my chin has been almost constantly broken out. I have tried numerous herbal and pharmaceutical methods, and now my hope is in homeopathy.

Eruptions occur in the form of mostly medium red bumps which hurt before they form and while they're there, and sometimes open up in pus-filled pimples which take a week or so to dry up and go away. They are concentrated at the corners of my mouth and jawline, and line between mouth corner and jaw. There are usually 3-4 spots at a time, and new ones every few days. Since they get worse a week or so before I menstruate, they may be linked to hormones. The spots are very painful - I put tea tree oil and lavender and calendula on them, but nothing has gotten rid of this problem. Two dermatologists have diagnosed the disease as perioral dermatitis.

What sort of homeopathic treatment would you recommend in this case?
Thank you so much!
