Keratosis pilaris is a common skin condition that affects millions of people worldwide. This harmless yet often frustrating condition causes small, rough bumps to appear on the skin, typically on the arms, thighs, and buttocks. While it’s not a serious medical issue, keratosis pilaris can be a source of discomfort and self-consciousness for those who have it.
Understanding keratosis pilaris is crucial to manage its symptoms effectively. This article delves into the nature of the condition, its common symptoms, and available treatment options. It also explores practical tips to live with keratosis pilaris and maintain healthy skin. By the end, readers will have a clear grasp of this skin condition and know how to address it.
What is Keratosis Pilaris?
Keratosis pilaris is a common skin condition that causes patches of rough, small bumps to appear on the skin, typically on the upper arms, thighs, cheeks, or buttocks. These tiny bumps resemble goosebumps or the skin of a plucked chicken, which is why it is often referred to as “chicken skin.” The condition is harmless and not contagious, and the bumps usually do not cause discomfort or itching.
The most notable symptom of keratosis pilaris is its appearance. The bumps can appear in different colors depending on the person’s skin tone, ranging from flesh-colored, white, red, pink, brown, or black. They may also be accompanied by slight discoloration around the bumps, itchy or irritable skin, and dryness. The bumps often feel like sandpaper to the touch.

Causes
Keratosis pilaris results from a buildup of keratin, a hair protein, in the pores. When keratin clogs the pores, it blocks the opening of growing hair follicles, causing small bumps to form over where a hair should be. The exact cause of this keratin buildup is unknown, but doctors believe it may be associated with skin conditions such as atopic dermatitis and genetic factors.
Risk Factors
While anyone can develop keratosis pilaris, it is more common in certain groups of people. Women, children, and teenagers are more likely to have this condition, as well as those with dry skin, eczema, ichthyosis, hay fever, or obesity. Keratosis pilaris often begins in late infancy or adolescence and typically clears up by the mid-20s, with most cases completely resolving by age 30. Hormonal changes during puberty and pregnancy can also trigger flare-ups. Additionally, people with fair skin are more prone to developing keratosis pilaris compared to those with darker skin tones.
Common Symptoms of Keratosis Pilaris
The most notable symptom of keratosis pilaris is its appearance. The visible bumps appearing on the skin resemble goosebumps or the skin of a plucked chicken, which is why it is often referred to as “chicken skin.” The bumps can appear in different colors depending on the person’s skin tone, ranging from flesh-colored, white, red, pink, brown, or black. They may also be accompanied by slight discoloration around the bumps.
Other symptoms associated with keratosis pilaris include:
- Itchy or irritable skin
- Dry skin
- Bumps that feel like sandpaper to the touch
Affected Areas
Keratosis pilaris commonly occurs on the upper arms, thighs, cheeks, or buttocks. The bumps can appear anywhere on the skin where hair follicles exist, but they will never appear on the soles of your feet or palms of your hands. It can extend to the forearms and lower legs as well.

Associated Discomfort
While keratosis pilaris bumps usually do not cause discomfort or itching, the skin around the bumps might be itchy and dry. However, if the bumps are painful when pressed, it may indicate a different condition, and it is best to consult a dermatologist for proper diagnosis.
It is important to note that keratosis pilaris should not hurt or cause pain when pressed. If your rash is causing you severe pain or discomfort, seek the care of an experienced dermatologist for proper diagnosis and treatment.
Diagnosis and Treatment Options
Keratosis pilaris is diagnosed based on medical history and a physical exam. A dermatologist can typically confirm the diagnosis by looking at the affected area. Factors that go into the diagnosis include age, appearance of the skin, and which areas are affected. There is no formal testing to confirm the diagnosis.
While there’s no known cure for keratosis pilaris, it usually clears up on its own with age. Many treatment options and skin care recipes are available for managing keratosis pilaris. Patients can have very good temporary improvement following a regular skin care program, but treatment needs to be continuous as the condition is generally controllable but incurable.
Medical Diagnosis
Keratosis pilaris is diagnosed based on:
- Medical history
- Physical examination by a dermatologist
- Evaluating factors such as age, skin appearance, and affected areas
No formal testing is required to confirm the diagnosis.
Over-the-Counter Treatments
Mild cases of keratosis pilaris may be improved with basic lubrication using over-the-counter moisturizer lotions such as:
- Cetaphil
- Purpose
- Lubriderm
Exfoliation is helpful in removing the small keratin plugs overlying follicles. Additional available therapeutic options for more involved cases include:
- Lactic acid lotions (AmLactin, Lac-Hydrin)
- Alpha hydroxy acid lotions (glycolic body lotions)
- Urea cream (Carmol 10, Carmol 20, Carmol 40, Urix 40)
- Salicylic acid (Salex lotion)
Prescription Medications
For more resistant cases, dermatologists may prescribe:
- Topical retinoid creams such as adapalene (Differin)
- Azelaic acid
- Topical steroid creams
- Topical immunomodulators
Physicians may also prescribe a medium potency, emollient-based topical steroid cream to be applied for inflamed, red rash areas. Once the inflammation has remitted, the residual dry rough bumps may be treated with a compounded preparation of salicylic acid in urea cream.
Photodynamic therapy (PDT) using a combination of a topical photosensitizer and a light source may be used for temporary treatment. Laser therapies have been used in severe cases, but there are no studies showing a permanent cure with these methods.
Living with Keratosis Pilaris
While keratosis pilaris is a harmless condition, it can still be a source of discomfort and self-consciousness for those who have it. Fortunately, there are several ways to manage the symptoms and maintain healthy skin.
Skincare Tips
Moisturizing is key to managing keratosis pilaris. Applying a thick, oil-free cream or ointment can help prevent dry skin and reduce the appearance of bumps. Look for moisturizers containing ingredients like urea or lactic acid, which can help exfoliate and soften the skin. Apply moisturizer to damp skin within 5 minutes of bathing for best results.
Gentle exfoliation can also help remove dead skin cells and improve skin texture. Use a loofah, buff puff, or rough washcloth to gently slough off dead cells, but avoid scrubbing too hard, as this can irritate the skin and worsen keratosis pilaris.
In addition to moisturizing and exfoliating, it’s important to use a mild cleanser and take short, warm (not hot) showers or baths to prevent drying out the skin. Limit bathing to once a day and avoid using harsh soaps or detergents that can irritate the skin.
Lifestyle Adjustments
Certain lifestyle factors can also impact keratosis pilaris. Wearing tight clothing can cause friction on the skin and irritate the condition, so opt for loose, breathable fabrics instead. If you’re prone to dry skin, using a humidifier can help add moisture to the air and prevent flare-ups.
When it comes to hair removal, shaving or waxing can sometimes cause more bumps to appear. If this is a concern, consider alternative methods like laser hair removal, which can remove hair without causing a flare-up.
Finally, while it may be tempting to hide keratosis pilaris with self-tanner, this can actually make the bumps more noticeable. Embrace your natural skin tone and focus on maintaining healthy, moisturized skin instead.

When to See a Doctor
If at-home treatments and lifestyle adjustments aren’t providing relief, it may be time to see a dermatologist. They can prescribe stronger topical creams or recommend in-office treatments like laser therapy to help reduce the appearance of keratosis pilaris.
It’s also important to see a doctor if you’re experiencing severe itching, pain, or discomfort, as this may indicate an underlying skin condition that requires medical attention.
