Sunspots, also known as solar lentigines or liver spots, are hyper-pigmented areas of the skin that result from long-term exposure to ultraviolet (UV) radiation from the sun or tanning beds. These lesions are characterised by an accumulation of melanin in the epidermis, leading to flat, brown or black discolouration, typically found on sun-exposed areas such as the face, hands, and arms.
While sunspots are benign and do not pose a health risk, many individuals seek to remove them for cosmetic purposes. Various treatments such as chemical peels and cryotherapy can be effective in reducing the appearance of sunspots. Additionally, preventive measures such as using broad-spectrum sunscreen and limiting sun exposure can minimise the development of these lesions.
