If you have small, painless bumps on your chest that resemble goose bumps or the skin of a plucked chicken, you may have a skin condition known as keratosis pilaris, or chicken skin. This condition is caused by a build-up of keratin, a protein found in skin, hair, and nails, which blocks the hair follicles or pores in your skin. While keratosis pilaris is mostly harmless and usually doesn't require medical treatment, it can cause itching or irritation and may lead to scarring if the bumps are scratched.

What You'll Learn

Chicken skin is a harmless condition
Chicken skin, or keratosis pilaris, is a harmless skin condition that is very common. It is characterised by small, painless bumps on the skin that look like goose bumps or the skin of a plucked chicken. These bumps are caused by a build-up of keratin, a protein that helps form hair, nails, and skin, around hair follicles. While the exact cause of this build-up is unknown, it is thought to be linked to genetic factors and skin conditions such as eczema and atopic dermatitis.
Keratosis pilaris is a benign condition that does not pose any health risks. It is so common that many dermatologists consider it a skin type rather than a medical condition. About 50-80% of teenagers and 40% of adults will develop these bumps at some point in their lives. The condition typically appears on the upper arms, thighs, cheeks, or buttocks but can occur anywhere on the body that has hair follicles. It is important to note that keratosis pilaris will never appear on the soles of the feet or palms of the hands, as these areas do not have hair follicles.
The bumps of keratosis pilaris can vary in colour, appearing white, red, pink, brown, black, or the same colour as the surrounding skin. They may also feel rough, similar to sandpaper, and can sometimes cause itching or irritation. In some cases, the bumps may become inflamed and lead to scarring. While the condition is generally harmless, it can cause feelings of self-consciousness or insecurity about one's appearance.
Keratosis pilaris typically develops in late infancy or adolescence and tends to clear up by the age of 30. It is more common in children and teenagers and may be influenced by hormonal changes during puberty and pregnancy. The condition is also more apparent in the winter months when the air is drier, which can worsen the symptoms. While there is no cure for keratosis pilaris, it can be managed with treatments such as moisturisers, exfoliating treatments, warm baths, and hydrating lotions.

It's caused by excess keratin
It's likely that you have a skin condition known as keratosis pilaris, sometimes called "chicken skin". This condition is caused by excess keratin, a substance found in skin, hair, and nails, blocking your hair follicles or pores. The excess keratin forms small, painless bumps that can be the same colour as your skin or appear red, white, brown, or black, depending on skin tone. These bumps can make your skin feel like sandpaper and may cause itching or irritation.
Keratosis pilaris is a very common and harmless skin condition that can affect people of any age, though it is most common in children, adolescents, and teenagers, and usually disappears by age 30. It typically appears on the upper arms, thighs, cheeks, or buttocks, but it can appear anywhere on the body that has hair follicles, such as the chest. The exact cause of keratin buildup leading to keratosis pilaris is unknown, but it is thought to have a genetic component and may be associated with other skin conditions such as eczema, dermatitis, or allergies.
If you are concerned about your symptoms, it is recommended to contact your healthcare provider. They can examine your skin and determine the best course of treatment. While there is no cure for keratosis pilaris, there are several treatments that can help manage the condition, including moisturisers, exfoliating treatments, warm baths, and hydrating lotions. Using mild, unperfumed soaps and bathing products can also help to prevent drying out the skin.

It can affect anyone, but is most common in children and teenagers
Keratosis pilaris, also known as "chicken skin", is a common and harmless skin condition. It is characterised by small, rough bumps on the skin that can be flesh-coloured, white, red, pink, brown, or black, depending on skin tone. These bumps are caused by a build-up of keratin, a protein found in skin, hair, and nails, which blocks the hair follicles or pores. While anyone can develop keratosis pilaris, it is most prevalent in children and adolescents, typically appearing in late infancy or adolescence. It is estimated that about 50% to 80% of teenagers and 40% of adults will experience this condition at some point in their lives.
The exact cause of keratin build-up leading to keratosis pilaris is not fully understood by researchers. However, it is believed that certain genetic factors play a role. People with close blood relatives who have or had keratosis pilaris are more likely to develop the condition themselves. Additionally, there may be a link to specific genetic mutations involving filaggrin, a crucial protein for maintaining the skin barrier.
Hormonal changes during puberty and pregnancy can also trigger or exacerbate keratosis pilaris. The condition tends to improve and often completely disappears by early adulthood, typically around the age of 30. While keratosis pilaris does not pose any health risks and usually does not require medical treatment, it may cause self-consciousness or insecurity about one's appearance.
The condition can affect any part of the body that has hair follicles, including the chest area. However, it is most commonly found on the upper arms, thighs, cheeks, and buttocks. The bumps may sometimes become red and inflamed due to itching or irritation, leading to scarring. During the winter months, when the air is drier, the condition may worsen, causing the skin to feel like sandpaper.

It may be caused by genetic factors
The skin condition you are describing is called keratosis pilaris, also known as "chicken skin". It is a common and mostly harmless skin condition that causes small, rough bumps or patches on the skin. These bumps can be flesh-coloured, white, red, pink, brown, or black, depending on skin tone, and may be mistaken for acne pimples or goosebumps. While the exact cause of keratin buildup is unknown, it is believed that keratosis pilaris may be caused by certain genes that create excess keratin, a protein that helps form hair, nails, and skin. This excess keratin can block hair follicles or pores, leading to the formation of small, hard bumps.
Keratosis pilaris is often a mild condition that does not require medical treatment. It usually goes away by itself by the age of 30. However, if the bumps cause itching or irritation, they may become red and slightly inflamed, potentially leading to scarring. Many bumps also contain ingrown hairs. Therefore, it is important to treat the skin gently and avoid scratching or rubbing the affected areas.
The condition tends to worsen during the winter months when the air is drier, and it may improve during the summer when humidity is higher. It is also associated with skin conditions such as eczema, atopic dermatitis, and allergies. If you have any of these conditions, you are more likely to develop keratosis pilaris. Additionally, keratosis pilaris may be linked to vitamin A deficiency, so taking supplements or using moisturisers containing vitamin A may help treat the condition.
While there is no cure for keratosis pilaris, certain treatments can help manage the condition and reduce the appearance of bumps. These include moisturisers, exfoliating treatments, warm baths, and hydrating lotions. It is also recommended to avoid harsh chemicals when bathing and to use mild, unperfumed soaps and bathing products. In some cases, medicated creams or laser treatments may be necessary, although these are typically not covered by insurance as they have not been proven highly effective.

There is no cure, but it can be treated
Keratosis pilaris, sometimes called "chicken skin", is a common skin condition that causes patches of rough bumps to appear on the skin. These tiny bumps are caused by a build-up of keratin, a protein that helps form hair, nails, and skin. While there is no cure for keratosis pilaris, it typically clears up on its own by the time a person reaches the age of 30. The condition is mostly found in children and adolescents and usually results in small, hard lumps on the skin. The bumps can be flesh-coloured, white, red, pink, brown, or black, depending on skin tone.
There are several ways to manage keratosis pilaris and prevent it from worsening. Firstly, it is important to treat the skin gently and avoid harsh chemicals when bathing or showering. Lukewarm water and mild exfoliating soaps or body washes can help to keep the skin hydrated and minimise the appearance of bumps. Additionally, moisturising the skin daily with creams containing lanolin, petroleum jelly, or glycerine can help to ease symptoms. Medicated creams are also available over the counter to help reduce keratin build-up.
Another way to manage keratosis pilaris is to take short, warm baths, which can help to unclog and loosen pores. Exfoliating the skin daily with a loofah, washcloth, or exfoliating gel can also improve the appearance of the skin by removing dead skin cells. However, it is important not to scrub too hard, as this can irritate the skin and make symptoms worse. Laser treatments performed by dermatologists can also help to improve the discolouration associated with keratosis pilaris.
Finally, it is recommended to avoid wearing tight clothing, as this can cause friction and irritate the skin. Using a humidifier can help to maintain moisture in the skin and prevent itchy flare-ups. While these treatments may not cure keratosis pilaris, they can help to minimise the appearance of bumps and improve overall skin health.
