What are sunspots?
Sun spots, also known as age spots or liver spots, are dark, pigmented patches that appear on the skin as a result of excessive sun exposure. They are caused by a buildup of melanin, the pigment that gives the skin color. Although mostly harmless, they can affect the overall appearance of your skin.
Different types of sunspots
There are several types of liver spots that can occur in multiple areas of the skin. Here are some of the most common types:
Lentigo solaris (age spots)
These spots are usually round or oval in shape and are common in people over the age of 50. They appear mainly on parts of the skin most exposed to the sun, such as the hands and shoulders. Age spots are usually light brown to dark brown in color.
Lentigo simplex, also known as Lentigo, refers to a common type of sun spots on the skin, characterized by light brown color. It affects people of all ages and has variable size and shape. Although usually harmless, they can cause cosmetic discomfort, especially on visible areas of the skin.
Ephelids, or freckles, are small light brown spots on the skin that are genetic and often occur in people with fair skin. These charming features can vary in number and intensity, influenced by hereditary factors and sun exposure.
Melasma is a type of sunspot that occurs mainly in women and is associated with hormonal changes, such as pregnancy. It causes dark, uneven patches on it the cheeks and forehead.
This type of sunspot occurs after inflammation or damage to the skin, such as acne or wounds. The discoloration can range from reddish to dark brown and often occurs in people with darker skin tones.
Sunspots can form on different parts of the skin that are frequently exposed to sunlight. This includes the face, hands, arms and shoulders, cleavage, back and legs.
Sun spots face
The face, especially the cheeks, nose, forehead and chin, is one of the most prominent areas sensitive to sun exposure. The delicate skin on these areas can easily react to the damaging effects of UV rays, causing liver spots. Especially in summer, when we spend more time outdoors, these areas can develop dark spots due to overexposure to the sun.
Hands and fingers
The skin of the hands and fingers is thin and sensitive, making it a common location for sunspots. These parts of the body are often uncovered and regularly exposed to the sun, especially during daily activities and outdoor activities. With aging, dark spots may form in these areas, which can be a visible sign of aging.
Legs and knees
In addition to the face and hands, liver spots can also manifest on the legs and knees, especially in people who like to exercise outdoors in shorts or skirts. Activities such as jogging, biking or walking expose these parts of the body to the sun, increasing the risk of hyperpigmentation.
The causes of sunspots
Sunspots are dark discolorations of the skin that occur due to various factors, the main cause of which is sun exposure. Here we dive deeper into the causes:
UV exposure: The primary cause of liver spots is excessive exposure to ultraviolet (UV) rays from the sun. UV rays can lead to overproduction of melanin, the pigment responsible for the color of our skin. This results in dark spots becoming visible on the skin.
Sunburn: Severe sunburn can damage the skin and disrupt melanin production, leading to the formation of sunspots. Individuals who have suffered repeated sunburns, especially at a young age, have an increased risk of hyperpigmentation later in life.
Hormonal changes: Hormonal fluctuations can also contribute to the development of this condition. Pregnancy, contraceptive use and hormonal treatments can lead to increased sensitivity to the sun and hyperpigmentation.
Skin type: People with fair skin are generally more susceptible to sunspots than those with darker skin. This is because melanin provides less protection from UV rays in people with lighter skin tones.
Heredity: Genetic predisposition also plays a role in susceptibility to this condition. If other family members have developed this condition, you may also be at greater risk.
Age: As we age, our skin becomes more sensitive to the harmful effects of the sun. As a result, liver spots and other forms of hyperpigmentation can develop over the years.
Inflammation and damage: Inflammations or injuries to the skin, such as acne, can lead to the formation of post-inflammatory hyperpigmentation, resulting in dark spots on the affected areas.
Removing sun spots
Sun spots can be undesirable, but there are several treatment options available to reduce or even remove them. Here are some effective methods to tackle these stains:
Skin care products: There are several skin care products on the market that contain ingredients such as hydroquinone, glycolic acid, vitamin C and niacinamide. These ingredients can help reduce hyperpigmentation by regulating melanin production and exfoliating dead skin cells.
Laser treatments: Laser technologies, such as intense pulsed light (IPL) and fractional lasers, can be used to reduce sunspots. These treatments target pigment cells and break down excess melanin, gradually fading the spots.
Topical retinoids: Retinoids are derivatives of vitamin A and can help regulate skin cell renewal and reduce hyperpigmentation. They can improve skin texture and fade blemishes. The use of these retinoids should always be done under the supervision of a physician.
Cryotherapy: In cryotherapy, sunspots are treated by freezing them with liquid nitrogen. This leads to the shedding of the top layer of skin, allowing new, healthy skin cells to rise to the surface.
Medical peels: Medical peels, performed by professionals, can target deeper layers of the skin and reduce severe hyperpigmentation. However, these treatments should be carefully considered and performed under the guidance of an experienced specialist.
Removing sun spots
Preventing and reducing sunspots requires attention to sun protection and a good skin care routine. Here are some valuable tips to prevent and reduce them:
Wear sunscreen: Using a broad spectrum sunscreen with a high SPF is essential. Apply generously to exposed skin, even on cloudy days. Repeat every few hours and after swimming or sweating.
Protective clothing: Wear protective clothing, such as hats and long sleeves, to protect skin from direct sunlight. This minimizes skin exposure to harmful UV rays.
Avoid overexposure: Try to avoid the sun during peak hours (between 10 a.m. and 4 p.m.) when UV radiation is strongest. Make use of beach or outdoor umbrellas to create shade and minimize direct sun exposure.
Skin care with antioxidants: Use skin care products with antioxidants, such as vitamin C and vitamin E, which can help fight free radical damage and maintain a healthy skin tone.
Hydration: Hydrated skin is more resilient and better able to recover from damage. Drink plenty of water and use moisturizers to keep skin healthy.
Healthy lifestyle: A healthy lifestyle, including a balanced diet and adequate sleep, contributes to radiant skin.
