Why is the acne on the chin almost a year and still not cured? And it's getting hotter?
The growth of acne has a great relationship with environment, inflammation, drugs and mood. I suggest you use physical therapy. Blue light irradiation has a good effect, which can sterilize and promote acne regression, and has a good effect on cystic acne. Linyi Traditional Chinese Medicine Hospital has a good effect in treating acne with blue light, so you can go and have a look.
