A South African lady has shared the aftermath of rubbing her period blood on her face. @Tashimkhabela stated that period blood is good for the skin and went ahead to share a photo of the blood on her face. Apparently period blood is good for clear skin. has anyone tried it? Update: There’s blood on my face. it dried fast. It actually has no weird smell. Apparently I’m supposed to leave it on for 15-20 minutes.
