Keratosis pilaris is a common skin condition characterized by small, rough bumps on the skin, typically on the upper arms, thighs, and buttocks. Although harmless, it can be unsightly and cause itching and irritation. Keratosis pilaris often appears due to a buildup of keratin, a protein that protects the skin from infections and harmful substances. The condition tends to worsen during dry seasons when the skin becomes dehydrated. Regular exfoliation and moisturizing can help reduce the appearance of the bumps. While it can affect people of all ages, keratosis pilaris is more common in children and young adults.
What is Keratosis Pilaris?
Keratosis pilaris, also known as “chicken skin” or “strawberry skin,” is a common skin condition that affects individuals of all ages. It is characterized by the appearance of small, rough, and often itchy bumps on the skin. These bumps are caused by a buildup of keratin, a protein that is naturally found in the skin. Keratosis pilaris is not contagious and does not pose any serious health risks, but it can be unsightly and cause discomfort.1
Keratosis pilaris typically affects the upper arms, thighs, and buttocks, but it can also appear on the face, neck, and other areas of the body. The bumps are usually flesh-colored or slightly red, and they can range in size from small, barely noticeable bumps to larger, more prominent ones. In some cases, keratosis pilaris can also cause the skin to become dry, rough, and scaly.
Learn About This Common Skin Condition
Keratosis pilaris is a common skin condition that affects approximately 50-80% of adolescents and young adults. It is more prevalent in women than in men, and it tends to run in families. The exact cause of keratosis pilaris is not fully understood, but it is believed to be related to genetics, hormonal changes, and environmental factors.2
Keratosis pilaris is not a serious medical condition and does not require treatment. However, there are a number of things that individuals can do to help manage the symptoms and improve the appearance of their skin. These include:
- Using gentle cleansers and moisturizers
- Avoiding harsh soaps and scrubs
- Exfoliating the skin regularly
- Applying over-the-counter or prescription topical treatments
- Seeking professional treatment from a dermatologist
Understand Causes, Symptoms, and Treatments
The primary cause of keratosis pilaris is a buildup of keratin in the hair follicles. Keratin is a protein that is naturally produced by the body and helps to protect the skin. However, in individuals with keratosis pilaris, the keratin can become trapped in the hair follicles, leading to the formation of small, hard bumps.
In addition to the buildup of keratin, other factors that may contribute to the development of keratosis pilaris include:
- Genetics: Keratosis pilaris tends to run in families, suggesting that there may be a genetic component to the condition.
- Hormonal changes: Keratosis pilaris is often more severe during puberty and pregnancy, when hormone levels are fluctuating.
- Environmental factors: Dry weather, cold temperatures, and certain medications can also worsen keratosis pilaris.
The symptoms of keratosis pilaris can vary from person to person. Some individuals may only experience mild symptoms, while others may have more severe symptoms that can affect their quality of life. Common symptoms of keratosis pilaris include:
- Small, rough bumps on the skin
- Dry, rough, and scaly skin
- Itching and irritation
- Redness and inflammation
Preventing Keratosis Pilaris Flares
Although keratosis pilaris cannot be fully prevented, certain lifestyle changes and habits can help minimize flare-ups. Keeping the skin hydrated is essential, particularly during colder months when dryness is more common. Avoiding hot showers, which can strip the skin of natural oils, and opting for lukewarm water instead can prevent further irritation.
Wearing loose-fitting, breathable clothing can also reduce friction and irritation on the skin. Additionally, managing stress and maintaining a healthy diet rich in vitamins A and E may support overall skin health and reduce the severity of symptoms. Staying mindful of these preventive measures can help individuals with keratosis pilaris maintain smoother, more comfortable skin.
