Why do my lips look thinner as I age?

Over time, the lips and surrounding skin lose some of the collagen and elastic fibres that help them hold their shape. The visible pink part can become smaller and the border less distinct. Changes in the teeth and jaw may also affect how the lips are supported.

The change is usually gradual. There is no single age when it happens, and naturally thin lips are different from lips that have recently changed.

The skin between the nose and upper lip can lengthen with age, leaving less of the pink upper lip visible. This can make it look thinner even when lost fullness is only part of the explanation.

If it mainly disappears when you smile, lip movement matters too. The upper lip movement guide explains that concern.

Lip balm can improve dryness and make a rough surface look smoother. Correcting dehydration may also help dry lips, but neither restores fullness lost with age or shortens the skin above the upper lip.

A plain balm and sun protection are sensible skin care. Avoid products that repeatedly sting or irritate your lips in an attempt to make them look fuller.

That can be a reasonable goal, but definition and size are not completely separate. The right plan needs to account for the border, the amount of visible lip and how the lips move together. Simply adding more fullness can miss the reason an upper lip looks thin.

At Core Aesthetics, we compare the lips at rest and when smiling, then explain whether the change you want is realistic, which options are appropriate and the risks and costs. No treatment is also an option. Visit the lip consultation page for more detail.

Yes. Teeth and the jaw help support the lips, so missing teeth, dentures or changes in your bite can affect their position. Mention recent dental work or difficulty closing your lips. Dental advice may be more useful than cosmetic treatment when support or bite is the main issue.

Yes, if you have one that shows the change. An ordinary, unfiltered photograph can help explain what you miss about your previous lip shape. It is a reference for discussion, not a promise to recreate an earlier face.
