I've heard that it's supposed to be healthy to push back the cuticles growing over your fingernails...Is there any reason why?
It kind of makes the person's nail look like it's going to fall off his or her finger...

why does it look like the nail is going to fall off ? No, I dont think so. You are supposed to do it safely with an orange stick, very gently.

When your fingernails grow, the cuticle stretches with it. Therefore, you should push the cuticle back with a cuticle remover, which is a little stick designed for the cuticle. This process will promote your nail growth and health.

Thank you both. :)
