I am going to have hysteroscopy and d&c surgery in 2weeks. why i am not allowed to wear even a little make up ?

To see the real you: Your surgical team will only be able to monitor your condition optimally if they can see the color and condition of your nails and skin. If these are hidden by makeup or nail polish, it makes their job harder and can impair your safety during surgery and recovery. Hopefully, no one on your surgery team is going to be thinking about that level of your attractiveness. Later for that, ok?
