Some plastic surgery hospitals in South Korea have dynamic nose tip surgery, so that the nose after surgery can basically conform to the effect of natural nose.
But even so, it doesn't mean you can bump or twist your nose hard. After all, the nose itself is very fragile, and the nose without surgery is greatly impacted, which will also lead to nasal bone deformation or cartilage damage. Besides, it's okay at ordinary times, and no one likes to twist their noses all the time.
So don't worry that the nose will become crystal after the operation. Blowing your nose and the like is completely possible. However, it doesn't mean that you don't care at all. The protection you should do is indispensable, especially during the recovery period. You must not make do casually and follow the doctor's advice.
After all, you can make up your mind to have an operation. It's no big deal to be more exquisite, right?
I hope my answer can help you.
