What should you know about freezing sun spots?

Sun spots, also called solar lentigines or age spots, are flat brown marks linked with long-term ultraviolet exposure. They commonly occur on exposed skin such as the face, hands, shoulders, and chest. Freezing can irritate or destroy pigment-containing cells, but it may also leave temporary redness, a crust, lighter skin, or darker skin. A changing mark should not be treated as a cosmetic spot without examination.

Have a clinician assess a new, irregular, multicoloured, itchy, or bleeding mark first. Once a benign sun spot is established, options can include [Cryotherapy (Lesion Removal)](/treatments/surgical-dermatology/cryotherapy-lesion-removal/), [IPL Photofacial](/treatments/laser-and-energy/ipl-photofacial/), [Picosecond Laser Treatment](/treatments/laser-and-energy/picosecond-laser-treatment/), or a [Chemical Peel](/treatments/aesthetic-procedures/chemical-peel/). Daily broad-spectrum sun protection helps limit further darkening and new [Sun-Damaged Skin](/conditions/photoaging/).

Arrange prompt dermatology review if a spot changes in outline or colour, develops a persistent sore, crusts repeatedly, or bleeds without a clear injury. General [Dark Patches On Skin](/symptoms/dark-patches-on-skin/) or [Uneven Skin Tone](/symptoms/uneven-skin-tone/) may have causes other than sun spots and may need a different plan.

Ask how the mark was identified, whether freezing could alter its appearance, what pigment change is possible for your skin tone, and which treatment best matches your cosmetic goal.
