Keratosis pilaris (KP) skin, often referred to as "chicken skin," is caused by a buildup of keratin that blocks hair follicles.
While the exact reason for this keratin buildup is unknown, here's a breakdown of what's understood:
-
Keratin Buildup: KP occurs when keratin, a protein that protects skin from harmful substances and infection, accumulates and forms hard plugs within hair follicles. These plugs cause the characteristic small, bumpy texture associated with KP.
-
Genetic Predisposition: KP is thought to have a genetic component. This means that if your parents have KP, you are more likely to develop it as well. A family history of the condition is a significant risk factor.
-
Associated Conditions: KP is often seen in individuals with certain skin conditions, such as:
- Eczema (atopic dermatitis)
- Ichthyosis vulgaris (a condition causing dry, scaly skin)
- Dry skin
-
Other Potential Factors: While not definitively proven, other factors that may contribute to KP include:
- Allergies
- Hormonal changes
- Nutritional deficiencies
In summary, keratosis pilaris is primarily caused by the buildup of keratin in hair follicles, with a likely genetic component. While the precise mechanism isn't fully understood, associated conditions and other factors may contribute to its development.
