As we grow older, our skin naturally changes. One of the most noticeable changes—especially on areas exposed to the sun like the hands, face, and shoulders—is the appearance of small brown patches commonly called age spots or liver spots.
While many people think of them as a simple cosmetic concern, these marks can sometimes signal more than just aging. Understanding what’s normal and when to seek medical advice is important for both peace of mind and health.
Why Do Age Spots Appear?
Age spots are flat, oval, brown, or dark patches that form as a result of prolonged sun exposure. Ultraviolet (UV) rays speed up the production of melanin, the pigment responsible for skin color. Over time, this excess melanin clumps together, creating visible spots.
They are most common in adults over 50, but younger people who spend a lot of time in the sun or use tanning beds may also develop them.
Generally, age spots are harmless. They don’t cause pain, itching, or discomfort. Many people choose to live with them, while others pursue treatments—such as topical creams, chemical peels, laser therapy, or cryotherapy—to reduce their appearance for cosmetic reasons.
