A bump in the top region of the nose is most likely comprised of bone, whereas a hump in the lower region is usually cartilage. This can be addressed medically with rhinoplasty or non-surgically using dermal filler injections. 

A drooping nasal tip, as well as an unbalanced or wide-looking nose, can be corrected with dermal filler too. Dermal filler nose correction works by altering the dimensions and definition of the nose to make it seem slimmer, straighter, and more lifted.
