Old age spots, also called liver spots or sun lentigos, are flat, brown, grey or black spots that usually appear on areas of the skin exposed to the sun. They are more common in adults over the age of 50, but younger people can also have them if they spend a lot of time in the sun. Old age spots are caused by excessive production of melanin, the pigment that gives the skin its color. Factors such as prolonged exposure to the sun, ageing and genetic predisposition can contribute to their development.
Understanding the role of minerals in skin health
Minerals play a crucial role in maintaining healthy skin. They are involved in various biological processes, including cell regeneration, protection against oxidative stress and maintenance of the structural integrity of the skin. Essential minerals such as zinc, copper and selenium are particularly important for skin health, as they help to protect the skin from damage and support its natural repair mechanisms.
What is selenium and why is it important?
Selenium is an essential trace element for many body functions, including the maintenance of healthy skin. It is a powerful antioxidant that helps to protect cells from damage caused by free radicals, which are unstable molecules that can lead to premature aging and skin lesions. Selenium also supports the immune system and plays a role in the metabolism of thyroid hormones.
