As a dermatologist with over a decade of experience in skin health and aging, I've observed various changes in the skin as people age. One of the common changes is the development of a more bumpy or textured appearance on the nose and other areas of the face. This can be attributed to several factors:


1. Elasticity Loss: As we age, the skin loses its elasticity due to a decrease in collagen and elastin fibers. This can lead to sagging and a more uneven surface.


2. Sebaceous Gland Changes: The sebaceous glands, which are responsible for producing oil (sebum), can become enlarged and more active with age. This can result in a rougher texture and the appearance of enlarged pores.


3. Sun Damage: Prolonged exposure to the sun can cause damage to the skin, leading to a thickened, leathery texture, and potentially to the formation of actinic keratoses, which are rough, scaly patches.


4. Genetics: Some people are genetically predisposed to develop more pronounced skin changes with age.


5. Inflammation: Chronic inflammation from various skin conditions can also lead to a bumpy appearance.

It's important to note that while these changes are common, they are not universal, and the extent to which they occur can vary widely from person to person.
