Keratosis Pilaris

Overview

Keratosis pilaris is a common skin condition. It's harmless and causes small, rough bumps, often found on the upper arms, thighs, cheeks, or buttocks. These bumps are usually dry and don't cause pain or itching. Think of it like tiny, slightly raised pimples that are part of the skin's texture.

This condition is fairly typical and doesn't need to be treated aggressively. It's often seen as part of normal skin variation. There's no known cure, and you can't prevent it from developing. However, you can use moisturizing lotions and creams, or sometimes prescription-strength ones, to help make the bumps less noticeable and the skin feel smoother. Usually, the bumps lessen or even disappear by the time a person reaches their 30s.

Symptoms

Keratosis pilaris is a common skin condition that can affect people of all ages, but it's more frequent in young children. It's characterized by small, painless bumps that often appear on the upper arms, thighs, cheeks, or buttocks. These bumps can make the skin feel rough and dry in those areas. The problem often gets worse during times of low humidity, such as the winter, when the air is dry and your skin loses moisture. The bumps may resemble the tiny bumps you get when your skin is cold, or gooseflesh.

Usually, keratosis pilaris doesn't require any special treatment. However, if you're worried about the appearance or feel of your skin, or your child's skin, it's a good idea to talk to a doctor or a dermatologist (a skin specialist). They can assess the situation and provide appropriate advice.

When to see a doctor

Keratosis pilaris is a common skin condition that often doesn't require any special treatment. It's usually nothing to worry about. However, if you or your child have concerns about the appearance or feel of their skin, it's a good idea to talk to your doctor or a dermatologist. A dermatologist is a doctor who specializes in skin conditions. They can properly diagnose the issue and advise on any necessary steps.

Causes

Keratosis pilaris happens when a protein called keratin builds up and forms tiny, hard plugs in the openings of your hair follicles. These plugs are like tiny bumps that create rough, bumpy patches on the skin. Think of it like a tiny plug in the drain of a hair follicle. This happens in many hair follicles at once, leading to these noticeable skin patches.

Keratin is a tough protein that helps protect your skin from things like germs and the elements. Normally, keratin helps keep your skin healthy. But in people with keratosis pilaris, the body makes more keratin than it needs, or the keratin doesn't shed properly. This extra keratin gets stuck in the hair follicles, forming those bumps.

Scientists aren't entirely sure why this extra keratin buildup happens. It might be related to genetics, meaning it could run in families. Or, it could be connected to other skin conditions like eczema (atopic dermatitis). Dry skin can also worsen the problem, making the bumpy patches more noticeable and uncomfortable.

Risk factors

Keratosis pilaris is a fairly common skin condition. It often appears in multiple members of the same family. This suggests a genetic link, meaning a tendency for it to be passed down through generations. In simpler terms, if one or more people in your family have it, you might be more likely to develop it too.

Diagnosis

Your doctor can usually tell if you have keratosis pilaris just by examining your skin. No special tests are necessary. They'll look for rough, small bumps, often appearing on the upper arms, thighs, or cheeks. This is a common skin condition, and it's typically harmless.

Treatment

Keratosis pilaris often goes away on its own over time. In the meantime, there are ways to improve the appearance of the skin. If simple moisturizing and self-care don't help, a healthcare provider might recommend medicated creams.

Different Types of Medicated Creams:

  • Exfoliating creams: These creams contain ingredients like alpha hydroxy acid (AHA), lactic acid, salicylic acid, or urea. These ingredients help loosen and remove dead skin cells, making the skin softer and smoother. Think of them like gentle scrubs for your skin. They're also called topical exfoliants. Some are available over-the-counter (without a prescription), while others need a doctor's prescription, depending on the strength. Your doctor can tell you which is best for you and how often to use it. Be aware that these acids can sometimes irritate the skin, causing redness or a stinging sensation, so they may not be suitable for young children.

  • Creams that prevent clogged pores: These creams, called topical retinoids, come from vitamin A. They help skin cells grow and renew themselves, preventing hair follicles from becoming clogged. This helps to clear up the rough bumps. Examples include tretinoin (found in products like Retin-A) and tazarotene (found in products like Tazorac). These creams can sometimes dry or irritate the skin. If you're pregnant or breastfeeding, talk to your doctor before using these creams, as they might not be the best option or may need to be delayed.

Important Considerations:

Using these creams regularly can help improve the appearance of keratosis pilaris, but the condition may return if you stop using the creams. Even with treatment, keratosis pilaris can sometimes last for a long time.
