I received nose sculpting injections 3 times at Yan Clinic. 2 times as standard, and the 3rd time, I also received nose sculpting injections. The effect was good, and 2-3 weeks seemed to be the most effective. The nose sculpting injections seemed to make my nose swell more, so I don't think I would get the nose sculpting injections twice . It's worth getting an injection once in a while when you feel like it.
