If you have very dry skin, you may notice small, white bumps on your upper arms. According to the American Academy of Dermatology, these small bumps are common, benign features of a condition known as keratosis pilaris. This occurs frequently to people who have dry skin. Although it's more common in children and adults, anyone can develop keratosis pilaris.
Features
The main feature of keratosis pilaris is the presence of small, white or red bumps, usually most frequently found on your upper arms and thighs -- although they can also occur on your face. You may mistake them for acne, although the bumps tend to be hard and don't contain pus. The bumps are formed by an excess production of a skin protein known as keratin. According to the University of Maryland Medical Center, this protein accumulates and forms plugs in the hair follicles of people who have keratosis pilaris. The bumps may resemble goosebumps and feel like sandpaper.
Causes
The cause of keratosis pilaris is not fully understood. According to the University of Maryland Medical Center, it seems to run in families. Keratosis pilaris occurs more frequently to people who have very dry skin or eczema. Dry winter weather seems to exacerbate the condition.
Medical Treatments
Keratosis pilaris is a benign condition that may cause irritating symptoms. According to the American Academy of Dermatology, most people seek medical treatment to alleviate itching or reduce the appearance of the bumps. In these cases, topical retinoids or creams containing urea or lactic acid can help. Additionally, some people choose to have a chemical peel, which can help remove a buildup of excess skin and give the skin a smoother appearance. Because there is no cure for keratosis pilaris, treatments must be repeated continually, or the bumps will reappear.
Home Remedies
Certain home remedies and lifestyle changes may benefit those suffering from keratosis pilaris. According to MayoClinic.com, washing with warm water and avoiding soaking in hot water for long periods can help prevent your skin from becoming too dry. Immediately apply a moisturizing lotion to your skin after bathing, which helps keep moisture in your skin. During dry winter months, consider using a humidifier in your home or office to help add moisture to the air.
Warning
Seriously dry skin can lead to conditions such as eczema or dermatitis. If you've never been diagnosed with keratosis pilaris, consult your doctor in order to rule out the presence of another underlying skin condition.
