Keratosis is a common skin condition caused by too much keratin, a protein that makes up the outer layer of skin. It usually appears as a patch of thick, dry, scaly skin. Symptoms can range from mild to severe, depending on the type of keratosis and the underlying cause. Some common triggers of keratosis flare-ups include skin irritation, excessive sun exposure, and certain medications.
Sun Exposure
Excessive sun exposure is one of the most common triggers of keratosis flare-ups. Prolonged UV exposure can damage the skin, leading to dryness, itching, and other symptoms. It can also increase the risk of skin cancer. To reduce the risk of flare-ups, it’s important to protect the skin with sunscreen, hats, and protective clothing.
Skin Irritation
Skin irritation can also lead to keratosis flare-ups. Common irritants include fragrances, dyes, and other chemicals found in cosmetics, soaps, and detergents. It’s important to avoid contact with these irritants and to use gentle, hypoallergenic products.
Certain Medications
Certain medications can also trigger keratosis flare-ups. These include topical steroids and other medications that weaken the skin’s natural defenses. To reduce the risk of flare-ups, talk to your doctor about any medications you’re taking and ask if there are alternative treatments that won’t irritate your skin.
