Skin and Aging at a Glance
Skin and Aging: the whole thing in five minutes, for when you want the numbers and nothing else.
The changes in skin structure and function that come with age and cumulative UV exposure.
Key takeaways
- Main driver of visible aging on exposed skin: cumulative UV exposure
- Evidence-based topical: retinoids, with sunscreen
- Most useful single change: Use daily sun protection, which is the single most effective measure.
- Commonest mistake: Tanning beds.
- See a doctor if any of the signs under "When to speak to a doctor" below apply to you.
The numbers, in one place
| Measure | Figure |
|---|---|
| Main driver of visible aging on exposed skin | cumulative UV exposure |
| Evidence-based topical | retinoids, with sunscreen |
| Smoking | speeds up skin aging |
| Thinner skin with age | increases bruising and tearing risk |
In one paragraph
Most visible aging of exposed skin comes from sun damage rather than time alone, which makes it substantially preventable.
Worth doing
- Use daily sun protection, which is the single most effective measure
- Stop smoking
- Moisturize; older skin is drier and more fragile
- Check your skin regularly, as skin cancer risk rises with age
Worth avoiding
- Tanning beds
- Expensive products with no evidence over basic sun protection
- Dismissing new or changing spots as "just age spots"

When to speak to a doctor
See your doctor about any new, changing or non-healing skin spot, which becomes more common with age and should never be assumed to be a harmless age spot. Report skin tears, slow healing or easy bruising, which can reflect medicine effects or an underlying condition. Call 911 for a fall with a head injury in anyone taking blood thinners.

How this page was put together
Every figure, recommendation and warning above is taken from the guidance named in Where this comes from. Nothing on this page is inferred, summarized or generalized beyond what those bodies publish: where they give a number, it is their number, and where they are silent, so are we. Pages are rebuilt whenever the underlying record changes. Sign-off by a named clinician, where it has happened, is shown at the top of the page along with the date.
