Why does this happen? As we age, collagen and elastin fibers break down, allowing the skin to stretch and sag, thereby making the nose longer and droopier. Shorter, perkier noses tend to be associated with youth. For this reason, rhinoplasty is sometimes recommended along with anti-aging procedures (such as a face lift) in order to restore the nose to a more youthful appearance.
Drooping, however, is not the whole story. One more reason the nose may appear to grow larger as we age is that the surrounding areas of the face (the cheeks, the lips, and the "hollows" of the eyes) lose some of their volume. By comparison, then, the nose can appear larger. To improve on this, many people turn to the use of injectable dermal fillers and/or lip augmentation.
