The Real Reasons Behind Hand Spots According to Science**
Many people panic when they notice new spots on their hands, especially as they age. While viral posts often claim that these spots are a sign of something dangerous, the truth is more nuanced. Spots on the hands can appear for several different reasons, and most of them are completely harmless. However, in some cases, they can reveal something important about your health—so it’s worth paying attention.
Here is what science says about what those spots might really mean.
1. They Are Often a Sign of Sun Exposure
The most common reason people develop spots on their hands—especially after age 30—is sun damage. These are known as sunspots, liver spots, or age spots, and they form when your skin produces too much melanin after years of exposure to ultraviolet (UV) light.
What this means:
-
You’ve had long-term sun exposure
-
Your skin is reacting to UV damage
-
You may need better sun protection
Although these spots are usually harmless, dermatologists recommend using sunscreen daily on the hands because constant sun exposure accelerates aging and increases skin cancer risk.
2. They Might Indicate Hormonal Changes
Hormonal fluctuations can change the way your body produces pigment. This is very common in:
-
Pregnancy
-
Menopause
-
People taking hormonal medications
-
Thyroid imbalances
If your hand spots appear suddenly during a period of hormonal change, this is likely the cause and is usually harmless.
