Åldersfläck

Åldersfläck, also known as age spots or liver spots, are small, flat areas of darkened skin. They are most common in people over the age of 50, but can appear earlier, especially in those with a history of significant sun exposure. These spots are not indicative of liver problems, despite the common name "liver spots." Medically, they are referred to as solar lentigines.

The primary cause of åldersfläck is prolonged exposure to ultraviolet (UV) radiation from the sun or tanning beds. UV light stimulates the production of melanin, the pigment that gives skin its color. In areas that have received more sun over time, melanocytes can become overactive, leading to an uneven distribution of melanin and the formation of these distinct spots. They typically appear on sun-exposed areas such as the face, hands, shoulders, and forearms.

Åldersfläck are generally harmless and do not require medical treatment. However, if a spot changes in size, shape, color, or develops irregular borders, it is important to consult a dermatologist to rule out more serious conditions like melanoma. For cosmetic reasons, several treatments are available to lighten or remove åldersfläck, including topical creams, chemical peels, laser therapy, and cryotherapy. Prevention primarily involves consistent use of sunscreen and limiting excessive sun exposure.
