Freckles, sunspots, and other marks on the skin are common dermatological conditions. They are generally caused by overexposure to sunlight or, in some cases, genetics. Sunlight exposure leads to excessive melanin production, which can result in freckles, sunspots, and other marks on the skin. Freckles are typically small, red to brown spots that appear in clusters. Sunspots, which are larger, range from brown to black in color and develop over time, often on areas of the skin that have received more sun exposure.
Marks on the skin can also be caused by factors like injuries, acne, or other conditions. These scars or marks may be red or brown and can take time to fade away. To prevent them, it’s important to avoid prolonged sun exposure and use sunscreen regularly. Products containing niacinamide, vitamin C, or retinoids can help lighten these marks and promote an even skin tone. In some cases, people may also opt for laser therapy or home remedies to treat and reduce the appearance of freckles, sunspots, and other marks.
