What is Keratosis Pilaris?

Keratosis Pilaris (KP), often informally referred to as "chicken skin disease," is a common dermatological condition characterized by the appearance of small, raised bumps on the skin's surface. These bumps are typically dry, rough to the touch, and can resemble the texture of sandpaper or the skin of a plucked chicken.

While keratosis pilaris is harmless and doesn't cause discomfort or pain, it can be a cosmetic concern for some individuals.

The condition most frequently manifests in areas of the body where hair follicles are present, such as the outer arms, thighs, and buttocks. In some cases, keratosis pilaris can also affect the face.

The bumps are usually skin-coloured or slightly red and can vary in size. Although keratosis pilaris often begins in childhood, it may become more noticeable during adolescence and can persist into adulthood.

9 Types of Keratosis Pilaris

Keratosis Pilaris (KP) encompasses a range of distinctive variations, each characterized by specific features and occurrence patterns. Some prominent types of keratosis pilaris include:

Keratosis pilaris Rubra: This variant exhibits red and inflamed bumps, which can manifest on the arms, head, legs, and other body parts. The bumps are textured and accompanied by noticeable redness and irritation.
Keratosis pilaris Alba: In contrast to the redness of Rubra, keratosis pilaris Alba is characterized by rough and bumpy skin with minimal irritation or redness. The bumps are often flesh-coloured or slightly lighter than the surrounding skin.
Keratosis pilaris Rubra Faceii: Limited to the facial region, Rubra Faceii is marked by a reddish rash that emerges primarily on the cheeks. Small bumps and pronounced redness distinguish this type from other facial skin conditions.
Keratosis pilaris Atrophicans: This variant involves the appearance of bumps and atrophy or thinning of the skin over time. It can lead to changes in skin texture and overall appearance.
Keratosis Follicularis Spinulosa Decalvans: A more specific form, this type involves rough, bumpy skin and can lead to hair loss, particularly on the scalp.
Atrophoderma Vermiculatum: Atrophoderma Vermiculatum is characterized by small depressions in the skin, resembling the appearance of worm tracks.
Keratosis pilaris Atrophicans Faciei: Similar to other Atrophicans types, this variant impacts the face and may involve skin thinning, giving the affected area a sunken appearance.
Erythromelanosis Follicularis Faciei et Colli: This rare variant causes reddish-brown pigmentation around hair follicles on the face and neck, often combined with increased visibility of blood vessels.
Papular Profuse Precocious keratosis pilaris: A distinctive presentation of keratosis pilaris that occurs in childhood, characterized by numerous papules (small raised bumps) that emerge earlier than usual.

What are the Causes of Keratosis Pilaris?

The causes of Keratosis Pilaris (KP) are not fully identified. Still, it is believed to arise from a combination of genetic predisposition and the buildup of keratin within hair follicles.

Key factors contributing to the development of keratosis pilaris include:

Genetic Factors: Hereditary factors play a significant role in the occurrence of keratosis pilaris. The condition often runs in families, suggesting a genetic predisposition to its development. Individuals with a family history of keratosis pilaris are likely to experience it.
Keratin Accumulation: The central factor in keratosis pilaris's pathogenesis is the accumulation of keratin within hair follicles. When excess keratin builds up, it forms plugs that obstruct the hair follicles. This obstructive process gives rise to small bumps on the skin's surface.
Underlying Skin Conditions: Certain skin conditions, such as eczema (atopic dermatitis), can exacerbate the development of keratosis pilaris. Eczema-related skin dryness and inflammation can contribute to the buildup of keratin within hair follicles.
Dry Skin (Xerosis): Individuals with dry skin are more prone to developing keratosis pilaris. Dry skin lacks proper hydration and may contribute to the formation of keratin plugs within hair follicles.
Hormonal Changes: Hormonal fluctuations, particularly during puberty, can impact the skin's texture and sebum production (skin oil). These changes can influence the development of keratosis pilaris.

What are the Symptoms of Keratosis Pilaris?

Recognizing keratosis pilaris is relatively easy due to its distinct appearance. The symptoms, while primarily physical, can also have a psychological impact.

Painless tiny bumps on upper arms, thighs, cheeks, or buttocks
Dry and rough skin in affected areas, often worsening in low humidity
Slight discolouration around the bumps
Itchy and irritable skin
Presence of sandpaper-like skin in bump areas
Appearance of bumps resembling strawberry skin
Possible absence of symptoms beyond visual bumps
Worsening of bumps in drier conditions, notably during winter

What are the Risk Factors of Keratosis Pilaris?

Several factors contribute to an increased likelihood of developing Keratosis Pilaris (KP). Some of the major risk factors are mentioned below:

Family History: Individuals with close blood relatives with keratosis pilaris are more predisposed to developing the condition.
Skin Conditions: Certain skin conditions heighten the risk of keratosis pilaris, including eczema (atopic dermatitis) and ichthyosis vulgaris, characterized by very dry skin.
Medical Conditions: Medical conditions like asthma, hypothyroidism, Cushing’s syndrome, or diabetes can increase the likelihood of developing keratosis pilaris.
Body Weight: Excess body weight, leading to overweight or obesity, has been linked to a higher risk of developing keratosis pilaris.
Fair or Light Skin: Individuals with fair or light skin tones are more prone to develop keratosis pilaris.
Hay Fever: Hay fever is associated with an elevated risk of experiencing keratosis pilaris.
Melanoma Treatment: If you're undergoing treatment for melanoma using vemurafenib (Zelboraf®), a targeted therapy medicine, your risk of developing keratosis pilaris may increase.
Down Syndrome: Individuals with Down syndrome also face a heightened risk of developing keratosis pilaris.

What is the Diagnosis for Keratosis Pilaris?

Accurate diagnosis of keratosis pilaris involves visual examination, considering the distinct appearance of the bumps.

A healthcare provider examines the affected areas, such as the face (cheeks, neck, or under the eyes), legs (thighs), back, chest, butt, and forearms - looking for the presence of small, rough bumps that are a hallmark of keratosis pilaris.
Discolored, rough, itchy, dry, and painless bumps provide important diagnostic insights into keratosis pilaris.

What is the Treatment for Keratosis Pilaris?

While keratosis pilaris has no cure, numerous treatment options can effectively manage its symptoms and improve skin texture.

Use Moisturizers: Keeping the skin hydrated with moisturizers can soften and reduce the prominence of bumps. Opt for products containing ammonium lactate or alpha hydroxy acids.
Medicated Creams: Prescription-strength moisturizers or creams containing ingredients like urea, alpha hydroxy acids, salicylic acid, and glycolic acid can help reduce the appearance of keratosis pilaris.
Exfoliation: Gently exfoliate the affected areas using a loofah, washcloth, or exfoliating gel while bathing. Avoid excessive scrubbing, which can irritate the skin.
Laser Treatments: Dermatologists can perform laser treatments to address discolouration associated with keratosis pilaris.
Gentle Skincare: Modifying your skincare routine to combat dryness can lead to improvement. Use lukewarm water, mild exfoliating soaps to bathe, and moisturizers regularly.
Home Remedies: While not curative, certain home remedies can reduce the appearance of keratosis pilaris. Consider using apple cider vinegar, baking soda paste, and coconut oil and staying adequately hydrated.

What are Common Conditions that Occur with Keratosis Pilaris?

Keratosis pilaris might be accompanied by other skin conditions or associated with certain health factors.

Ichthyosis Vulgaris: Characterized by excessive dryness and scaling of the skin, ichthyosis vulgaris often co-occurs with keratosis pilaris due to shared underlying factors.
Xerosis (Dry Skin): The presence of keratosis pilaris can be correlated with xerosis, a condition characterized by abnormally dry skin.
Atopic Dermatitis (Eczema): While less common, keratosis pilaris can be associated with atopic dermatitis, a chronic inflammatory skin condition. This association sometimes extends to other atopic conditions like asthma and allergies.

Therefore, Keratosis Pilaris (KP) may not be a life-threatening condition, but it can significantly impact one's self-esteem and overall quality of life. This article must have helped you in understanding the nature of Keratosis Pilaris and its potential causes so that you can manage it with care and attention.

Remember, seeking advice from a dermatologist or healthcare professional is crucial, especially if Keratosis Pilaris is causing significant distress or if over-the-counter treatments are not providing the desired results.
