Asking Muslims again, Are girls women allowed to expose and show any skin ?

Salam Yes Muslim women are allowed to expose their skin of face and palm only to non mahram people

Women most cover their body , but hands and face can be shown , although there are scholars says face should be covered.But in general face and hands covering is not obligation.

Salam...

The power of women in her physical body is the foundation of sexual sin. Sex outside of marriage causes many problems has we know living in western societies illegitimate children disease, porn. Muslims hold woman responsible for these social problems by not showing thyself in such manner to have men form impure thoughts in the first place. If covered head to toe in black burkas that do not show curvatures of the female form, feet ankles,Muslim men can have contact with women and not be tempted by impure thoughts.

Covering skin is a cultural thing, not a religious one. It can be found in many Muslim countries, but, not all of them.

No they should know their place as women according to the Koran

sometimes they can show their arms but not usually. Yes they can show hands and feet.
