How to Temporarily Hide a Bump on Nose?

The best way to eliminate the nasal hump is with a rhinoplasty. Without surgery, the best way is with temporary fillers. This can make a significant difference, but you cannot have a rhinoplasty until the material is completely absorbed (1-2 years). Thick eyeglass frames and some hair styles can also help temporarily. 

Though use of dermal fillers is a great option, if you are saving up your money, you're right -- this may set you back a bit. There are a couple of other options. First, like Dr. Yoo said, you can use glasses. If you don't need prescription lenses, this is no problem. There are tons of affordable options online (Warby Parker makes cool glasses for under $100). Another option, if you're not opposed, is to use a bit of makeup or concealer to hide the shadow created by the hump. This will work from the front view, but obviously not from the side. Best of luck moving forward!
