I am 22 years old girl and have acne since 4 years. It all started with the large pus filled acne on my chin initially and later I got normal acne all over my face. It sometimes included red bumps inside my skin. After consulting with a derm, it significantly helped a bit. I have noticed that allot of acne pops out during ovulation period while my face is alot better the other days. And I started getting painful acne on chin, bumps and acne all over again like before. Please tell me the reason for the same and suggest me a permanent solution as I am alot worried because of it.
