Keratosis is a common skin condition that causes patches of thick, scaly skin. It's often referred to as "chicken skin" because it can resemble the texture of poultry skin. Keratosis can be caused by a variety of factors, including excessive sun exposure, dry skin, and genetics.
Symptoms of Keratosis
The most common symptom of keratosis is patches of thickened, scaly skin. These patches usually appear on the arms, legs, and face. They may be light or dark in color, and can range from pinhead-sized to larger than a quarter. Other symptoms may include itching, redness, and inflammation.
Causes of Keratosis
Keratosis can be caused by a variety of factors, including excessive sun exposure, dry skin, and genetics.
Excessive Sun Exposure: Prolonged exposure to the sun can cause the skin to produce excess amounts of the protein keratin, which can lead to the development of keratosis.
Dry Skin: Dry skin is a common cause of keratosis. Dry skin can be caused by environmental factors, such as cold temperatures and low humidity. It can also be caused by skin conditions, such as eczema and psoriasis.
Genetics: Certain genetic conditions, such as ichthyosis, can make a person more likely to develop keratosis.
Treatment of Keratosis
Keratosis can be treated with a variety of methods, including topical creams, laser treatments, and surgery.
Topical Creams: Topical creams, such as retinoids and salicylic acid, can be used to reduce the appearance of keratosis.
Laser Treatments: Laser treatments, such as photodynamic therapy and fractional laser resurfacing, can be used to remove the patches of thickened skin.
Surgery: In some cases, surgery may be necessary to remove the patches of thickened skin.
Prevention of Keratosis
Keratosis can be prevented by taking steps to protect your skin from the sun and by keeping your skin moisturized.
Sun Protection: Wear protective clothing, such as hats and long-sleeved shirts, when outdoors. Use sunscreen with an SPF of at least 30 and reapply every two hours.
Moisturize: Keep your skin hydrated by using a moisturizer every day. Use a moisturizer that contains ingredients such as ceramides and hyaluronic acid.
