Face shaving for women is an emerging trend. Some are shaving because they have hair issues they'd rather not have, but some are shaving as part of a beauty regime. Marilyn Monroe and Elizabeth Taylor allegedly did it, and they looked great. Although I suspect that's more down to good genes and a healthy diet.
You'll need to get a facial razor; these are blunter than your old Bic which you really ought to replace. Then use water and a lubrication on your face. Experts say that shaving foam is better than soap as it's slipperier and some have antiinflammatory ingredients too.
You can shave in the direction of hair growth, or against it for a closer cut. Shaving in the shower is recommended because it opens pores and softens hair.
How will this trend will affect those with hirsuitism? Women with polycystic ovary syndrome can develop facial hair which they may remove or leave, depending on their preference. It's certainly not the standard 'norm', whatever that is, for women to sport facial hair.
Although hirsut women are not paraded at the circus anymore, unkind 'hairshaming' words are often sent in their direction. Will a trend of faceshaving for women help? Possibly. It may make the subject less taboo, but on the other hand what are women actually doing when they shave? They are removing hair they think shouldn't be there.
Face shaving has to one of the less dangerous beauty treatments out there, unless you have really shaky hands and slippery shower floor. At least you aren't injecting your body with chemicals or undergoing a general anaesthetic.
Face shaving for women seems pretty harmless. If you have the time and inclination give it a shot if it makes you feel good. Perhaps it'll help you marry a load of rich men and iconically stand over a hot air vent a la Marilyn and Liz.
