Morning. I've always had a dark hairy top lip, worse B4 a period. I used creams for years, then resorted to tweezers. Really satisfying ;-).
R the hairs on your chin below the surface, i.e. black dots or do they grow ....... I constantly rub my fingers over my chin area (OCD) and have to get the tweezers when ever I feel anything ! Hormone upheaval can cause a lot of hair, i.e. in polycystic ovary syndrome.
I'll bump my thread "My Chin!" so that you can browse.
