Hyperkeratosis is a condition where there is an abnormal thickening of the outer layer of the skin, known as the stratum corneum. This thickening happens when there is an overproduction of keratin, a protein that forms the key structural material in the outer layer of human skin, as well as hair and nails. While hyperkeratosis itself is not typically harmful, it can be uncomfortable and may lead to other skin issues if left untreated.
Symptoms of hyperkeratosis include rough, dry, scaly, or thickened patches of skin. These patches may be lighter or darker than the surrounding skin. In some cases, the affected areas might be itchy or sore. Common types of hyperkeratosis include calluses and corns, caused by repeated friction or pressure on certain areas of the skin. Other forms, like keratosis pilaris, appear as tiny, rough bumps, often on the arms, thighs, cheeks, or buttocks.
Treating hyperkeratosis usually involves managing the symptoms and addressing the underlying causes. Regularly moisturizing the skin with thick creams or ointments can help keep it hydrated and reduce dryness. Using exfoliating treatments can remove excess layers of dead skin. For more severe cases, a healthcare professional may recommend prescription creams or other treatments. It’s also important to minimize friction and pressure on the affected areas by wearing comfortable footwear and protective gloves if necessary.
