Noticed Dark Spots Showing Up on Your Hands or Body? Here’s What You Need to Know

Dark spots on the hands, arms, or other parts of the body are very common, especially as people get older or spend a lot of time in the sun. Although they can look worrying, most of the time these marks are harmless and easy to manage.

This article explains what causes dark spots, how to reduce their appearance, and when it’s a good idea to talk to a skin specialist.

What Are Dark Spots?

Dark spots — also called age spots, sun spots, or hyperpigmentation — are small areas of skin that become darker than the surrounding skin. They can appear in different shapes and sizes, and usually show up on areas that get a lot of sun exposure, such as:

• Hands

• Forearms

• Face

• Shoulders

• Upper back

These spots often develop slowly over time and are more noticeable after years of sun exposure.

Common Causes of Dark Spots

1. Sun Exposure

The most common cause is UV rays. When the skin receives too much sun, it produces extra pigment (melanin) to protect itself — which can form dark spots.

2. Natural Aging

As the skin ages, it becomes more sensitive to sunlight. This makes dark spots more frequent, especially after the age of 40.

3. Hormonal Changes

Hormones can also affect pigmentation. Some people notice dark patches during pregnancy, while using certain medications, or due to hormonal imbalance.

4. Skin Inflammation

Any irritation or injury — such as a scratch, pimple, or rash — can leave behind a darker mark once it heals.
