Does waxing your eyebrows make you eyes droop?

A friend of mine recently told me that waxing your eyebrows makes them drop!! Ahhhhh, I know a women who i work with who used to get her lip waxed and ended up with lines around her month,she swears this is from all the waxing done when she was younger (she never smoked) I never get my legs waxed, or anything else (use creams, much kinder to your skin) But i do get my eyebrows waxed. Now im worried about the effect. Have a look at women beautician's they always look older once they p 30. What do you think?
