Keratosis Pilaris: Causes, Treatments, and When to See a Doctor - Dermatology

More Info

---

Keratosis pilaris, often referred to as "chicken skin," is a common and harmless skin condition characterized by small, rough bumps that typically appear on the upper arms, thighs, cheeks, and sometimes the lower legs. These bumps are caused by the buildup of keratin, a protein that protects the skin from infections and other harmful substances. In your case, the patches you see on the inner sides of your calves and the rough bumps on both legs could indeed be indicative of keratosis pilaris.


Causes of Keratosis Pilaris
The exact cause of keratosis pilaris is not fully understood, but it is believed to be related to genetic factors, as it often runs in families. The condition is more common in individuals with dry skin, eczema, or other skin conditions. Hormonal changes, such as those that occur during puberty or pregnancy, can also exacerbate the symptoms. Additionally, keratosis pilaris tends to be more prevalent in individuals with certain skin types, particularly those with fair skin.


Treatments for Keratosis Pilaris
While keratosis pilaris is not harmful and typically does not require medical treatment, many people seek ways to improve the appearance of their skin. Here are some common treatment options:
1. Moisturizers: Regularly applying a good moisturizer can help soften the bumps and improve the overall texture of the skin. Look for creams that contain urea, lactic acid, or glycolic acid, as these ingredients can help exfoliate the skin and reduce the buildup of keratin.

2. Exfoliating Agents: Over-the-counter exfoliating creams or lotions containing alpha hydroxy acids (AHAs) or beta hydroxy acids (BHAs) can help remove dead skin cells and prevent the hair follicles from becoming clogged.

3. Topical Retinoids: Prescription-strength retinoids can help promote cell turnover and prevent the buildup of keratin. However, these should be used under the guidance of a healthcare provider, as they can cause irritation.

4. Laser Therapy: In more severe cases, dermatologists may recommend laser treatments to reduce redness and improve the texture of the skin.


When to See a Doctor
You should consider seeing a dermatologist if:
- The bumps are causing significant discomfort or itching.

- You notice any changes in the appearance of the bumps, such as increased redness, swelling, or discharge.

- You have concerns about the diagnosis and want to rule out other skin conditions, such as folliculitis or eczema.


Prevention and Management
While there is no definitive way to prevent keratosis pilaris, maintaining good skin care practices can help manage the condition. Here are some tips:
- Hydration: Keep your skin well-hydrated by using moisturizers regularly, especially after bathing.

- Gentle Cleansing: Use mild soaps and avoid harsh scrubs that can irritate the skin.

- Avoid Hot Showers: Hot water can dry out the skin, so opt for lukewarm showers instead.

- Wear Loose Clothing: Tight clothing can irritate the skin and exacerbate the condition.

In summary, keratosis pilaris is a common skin condition that can be managed with proper skin care. While it is not necessary to see a doctor for treatment, consulting a dermatologist can provide you with tailored advice and treatment options if you are concerned about the appearance of your skin.
