Age spots—often called liver spots or solar lentigines—are flat areas of darker pigmentation that usually appear on skin frequently exposed to the sun, such as the face, hands, shoulders, and arms. They are most common in adults over the age of 50, but they can also develop earlier in life, especially in people who spend a lot of time outdoors.
These spots form when the skin produces excess melanin, the pigment responsible for skin color. Long-term sun exposure, natural aging, and genetic factors all influence their appearance. While age spots are generally harmless, many people look for ways to better understand why they develop and how skin health can be supported over time.
Why Minerals Matter for Skin Health
Healthy skin relies on a wide range of nutrients, including essential minerals. Minerals are involved in important processes such as cell renewal, protection against environmental stress, and maintaining the skin’s structure.
Among the most important minerals for skin health are zinc, copper, and selenium. These nutrients support the skin’s natural defense systems and help reduce damage caused by oxidative stress, which is linked to visible signs of aging.
What Is Selenium?
Selenium is a trace mineral that the body needs in small amounts. Despite its size, its role is significant. Selenium functions as an antioxidant, helping protect cells from damage caused by free radicals—unstable molecules that can contribute to premature aging.
In addition to supporting skin health, selenium also plays a role in immune function and thyroid hormone regulation, making it an important part of overall well-being.
Selenium and the Appearance of Age Spots
Low selenium levels may contribute to increased oxidative stress in the body. When the skin lacks adequate antioxidant protection, it can become more vulnerable to environmental factors such as ultraviolet (UV) radiation.
This increased stress may encourage excess melanin production, which can contribute to the formation of age spots over time. Maintaining adequate selenium intake may help support the skin’s natural protective processes.
What Research Suggests About Selenium and Skin
Scientific research has explored selenium’s role in protecting the skin from UV-related damage. Some studies suggest that selenium, especially when combined with other antioxidants, may help support skin elasticity and overall skin appearance.
While selenium is not a cure or treatment, these findings highlight its importance as part of a balanced nutritional approach to skin health.
Possible Signs of Low Selenium Levels
A lack of selenium may affect the body in various ways. General signs can include fatigue, reduced immune response, and muscle weakness. In terms of skin health, insufficient selenium may be associated with increased sensitivity to sun exposure and slower skin recovery.
Identifying and addressing nutritional gaps early can help support both skin health and overall wellness.
How to Maintain Healthy Selenium Levels
Most people can meet their selenium needs through a balanced diet. The recommended daily intake for adults is approximately 55 micrograms per day, though needs may vary depending on individual factors.
In some cases, dietary supplements may be considered, but they should be used carefully and preferably under professional guidance.
Foods That Naturally Contain Selenium
Selenium is present in a variety of everyday foods, including:
-
Brazil nuts (one of the richest sources)
-
Seafood such as tuna, sardines, and halibut
-
Eggs
-
Sunflower seeds
-
Whole grains
-
Lean meats and organ meats
Including a mix of these foods can help support adequate selenium intake.
Supplementation: What to Know
While selenium supplements can help in cases of deficiency, excessive intake can be harmful. Very high levels may cause unwanted side effects, so moderation is essential. Consulting a healthcare professional before starting supplements is generally recommended.
Other Ways to Support Skin and Reduce Age Spots
Selenium is just one piece of the puzzle. Additional skin-supporting habits include:
-
Using sunscreen daily
-
Wearing protective clothing when outdoors
-
Avoiding prolonged sun exposure during peak hours
-
Eating a diet rich in antioxidants
-
Staying hydrated and following a consistent skincare routine
Final Thoughts
Age spots are a common part of aging, but understanding the role of nutrition—especially minerals like selenium—can help support long-term skin health. When combined with sun protection and healthy lifestyle choices, proper nutrient intake may contribute to healthier-looking skin over time.
Small, consistent habits today can make a meaningful difference in how your skin ages tomorrow.
