What helps sun damage on the chest and hands?

Stand in front of a window and look at the V of the chest. Sun damage there usually shows as a mottled mix of brown freckling, fine red vessels and a crepe-paper texture that folds when the arms come together.

On the backs of the hands it looks like scattered brown spots, thinning skin and veins and tendons that have become more visible as the fat pad under the skin has shrunk.

These are three different problems sitting in the same square of skin, and each answers to a different tool.

Color: spots and redness

Brown spots and diffuse redness on the chest respond well to broad-spectrum light or to a pigment-targeting laser, in a series of sessions spaced weeks apart. The treated spots darken for a week or so, look like coffee grounds, then flake away.

Redness fades more gradually. On deeper skin tones the same devices carry a real risk of dark or light patches, and a test spot behind the shoulder before a full treatment is a fair thing to ask for.

Once color is cleared, the daily sunscreen habit decides how long it stays cleared.

Texture: crepe and fine lines

Crepey texture is thinning collagen. Light fractional resurfacing, microneedling with or without radiofrequency, and some superficial peels stimulate new collagen over months.

On the chest the settings sit well below what a face would receive, because a burn there heals slowly and can leave a mark that outlasts the original damage. Improvement is gradual and shows best in photos taken under the same light three months apart.

Volume: hands

When hands look old mainly because tendons and veins show, the problem is lost fat rather than the skin surface. A thin filler placed under the skin of the back of the hand, or a biostimulatory product that encourages collagen over time, softens that look.

Swelling for a week is usual, and the hands should be kept out of heavy gripping work for a day or two. Sun spots on the same hands are treated separately, usually first.

Next steps

Before choosing a fix, the evidence to check is a set of photos of the chest and hands under window light, plus an honest count of unprotected sun hours in a normal week.

A clinician should then say which of the three problems dominates and propose the lightest sequence that addresses it. The breakdown is what matters, not where it is asked for.

Ask specifically how settings will differ from the face, what the pigment risk is for the reader's skin tone, and how the chest will be kept out of the sun between sessions.

Regulations on sunscreen labelling are published for public comment in the federal government's daily record, the Federal Register, which is a dry but useful place to learn what "broad spectrum" is required to mean on a label.

For maintenance, the habit that does the most is unglamorous. A broad-spectrum sunscreen on the chest and hands every morning, reapplied after washing hands, and a hat and shade on bright days.

Shopping at a Sunday farmers market run by the SEE-LA nonprofit in Hollywood is a pleasant way to spend a morning, and it is exactly the kind of two-hour outdoor errand that undoes a light treatment when the chest is left bare.

How the desk checked this answer

The desk looked at this question because it is the one people ask after a facial treatment goes well and the mirror starts telling a different story from the neck down.

We read the published guidance on treating the neck, chest and hands and found the same warning repeated: fewer oil glands, thinner skin, slower repair, so use lower energy and expect more visits.

We cannot see the reader's skin, and we have no way of knowing how much sun it has had.

In field terms, the answer turns on whether the damage is mostly color, mostly texture or mostly lost volume, and a clinician settles that in the first minute of an exam.
