Cassandra Bankson gained popularity as the woman who perfected covering acne with makeup.
A surprising medical discovery, however, makes her an active participant in discussions about female reproductive health.
In July 2014, the model and YouTube star filmed a video explaining how she has two vaginas, two cervixes and two uteri -- a condition called uterus didelphys.
After years of heavy period bleeding and back pain, Bankson found out she'd been suffering from two menstruations a month.
The reason Bankson never knew is because she has only one vulva. Everything looked normal to her, although her pair of reproductive systems was quite unusual.
In an interview, Bankson told Barcroft TV the medical revelation impacts menstruation and her sex life.
To top off Bankson's discoveries, an MRI showed the young woman has only one kidney. It's been a whirlwind year.
Bankson first discussed her diagnosis on her YouTube channel.
