What is Keratosis Pilaris?
Keratosis Pilaris (KP) is a common skin condition characterized by bumpy skin. Medically, it involves an overgrowth of keratin, a protein in skin and hair, within the hair follicles. This leads to the formation of tiny, rough bumps, often accompanied by irritation and inflammation. KP commonly appears on the backs of the arms, fronts of the thighs, and occasionally on the buttocks. The friction from clothing in these areas may contribute to the condition, but this is not definitively proven.
What Causes Keratosis Pilaris?
KP doesn't have a single cause and varies from person to person. Possible factors include:
- Genetics: Family history plays a significant role.
- Hair Structure: Curly hair shafts may lead to keratin buildup.
- Skin Irritants: Chemicals like sodium lauryl/laureth sulfate and synthetic fragrances might cause low-level skin irritation, leading to KP.
- Medications: Certain treatments for melanoma can trigger KP.
Who Gets Keratosis Pilaris?
KP is more prevalent in children and adolescents but can affect anyone. It is more common in women and often linked with conditions like asthma or eczema. Genetics also influence susceptibility, as those with a family history of KP are more likely to develop it. People with dry skin or those who shave or wax regularly are also at higher risk. However, KP is not contagious, so there's no need to avoid those with the condition.
How Can I Make Keratosis Pilaris Go Away?
Treatment for KP often starts with over-the-counter or prescription chemical exfoliants, such as lactic acid, salicylic acid, glycolic acid, and retinoic acid. Steroids may also be prescribed. However, simpler, non-invasive methods are recommended first:
- Moisturize: Apply a natural body oil to wet skin immediately after showering to lock in moisture.
- Avoid Irritants: Eliminate sodium lauryl/laureth sulfate and synthetic fragrances from all personal care and cleaning products.
- Moderate Shower Habits: Avoid super hot showers or baths, as they can dry out the skin.
- Use a Humidifier: In dry climates, a humidifier can help maintain skin moisture.
- Gentle Exfoliation: Exfoliate once or twice a week with a washcloth or gentle exfoliating product. Over-exfoliation can worsen inflammation.
- Natural Soaps: Switch to organic, hand-crafted bar soaps that retain glycerin to help draw moisture into the skin. Soaps with pumpkin or tomato can provide natural fruit acids and enzymes.
If these measures don't alleviate the symptoms, consulting a dermatologist for prescription options or laser therapy may be necessary. Consistent care and a healthy lifestyle can significantly reduce KP symptoms, often leading to smoother skin. Many individuals have successfully managed their KP with natural products like salt scrubs and body oils, reporting significant improvements.
