Age spots, also known as liver spots or solar lentigines, are flat brown or gray patches that appear on sun-exposed skin. While they are most common in adults over 50, younger people who spend a lot of time outdoors can develop them as well. These spots form when the skin produces excess melanin, often triggered by long-term sun exposure, natural aging, and genetic factors. Understanding what causes them is the first step in protecting and improving overall skin health.

Minerals play an essential role in maintaining healthy, resilient skin. Among them, selenium stands out for its antioxidant power. This trace mineral helps protect skin cells from free-radical damage, supports immune function, and assists with natural repair processes. When selenium levels are too low, the skin becomes more vulnerable to oxidative stress, which can accelerate melanin overproduction and contribute to the formation of age spots.

Scientific research shows that selenium can help defend against UV-induced skin damage and may reduce the appearance of age spots when combined with other antioxidants. However, deficiency symptoms—such as fatigue, slower healing, and increased sun sensitivity—can easily go unnoticed. Ensuring proper intake through diet is essential, with foods like Brazil nuts, seafood, eggs, and whole grains offering rich natural sources.

While selenium is beneficial, prevention requires a broader approach. Daily sunscreen use, protective clothing, hydration, and a balanced antioxidant-rich diet remain key. When combined with healthy mineral levels, these habits support smoother, stronger, and more youthful-looking skin while reducing the risk of developing age spots over time.
