Age spots on the backs of the hands

Their medical name is solar lentigines. The hands accumulate ultraviolet exposure during everyday activities, and sunscreen is easily removed by washing, which helps explain why pigment marks can become prominent there.

A usual age spot is a discrete tan-to-brown macule: it is flat, has no scale and feels like adjacent skin. Similar colour does not make every hand lesion an age spot. A rough patch may reflect sun-related surface damage, while a raised or waxy growth represents another type of lesion.

Comparing both hands can reveal the broader pattern, but each standout mark deserves individual attention. A dermatologist may use magnification to inspect pigment structures that cannot be judged reliably at home.

Apply broad-spectrum sunscreen over the backs of the hands before sun exposure and renew it after handwashing or when it has rubbed off. Driving gloves, long cuffs or shade add protection. Moisturizer can support the skin barrier but does not remove pigment by itself.

For a confirmed solar lentigo, a clinician may offer a topical treatment, chemical peel, cryotherapy, intense pulsed light or laser. Hands can heal with temporary redness, crusting and pigment alteration, and treatment may not make every mark match the surrounding skin. Do not use household freezing kits or corrosive liquids on an undiagnosed spot.

Arrange assessment when one mark looks distinctly different from the rest or changes in size, outline, colour or height. Bleeding, persistent scale, an open area, tenderness or recurrent crusting are additional reasons for review.

A rapidly inflamed hand with spreading redness, warmth, swelling or discharge needs prompt medical attention, especially after a procedure, because those features can indicate infection rather than ordinary treatment recovery.

Ask how the diagnosis was confirmed, which method offers the most suitable balance of improvement and pigment risk for your hands, how long to protect the treated skin, and which recovery changes should trigger a call.
