Keratosis Pilaris (KP) is an incredibly common and benign skin condition, often referred to as 'strawberry legs' or, less endearingly, 'chicken skin'. It's characterised by small, pimple-like bumps that feel rough to the touch, typically appearing on the back of the upper arms and sometimes on the legs, particularly the thighs.
Keratosis Pilaris is genetic. While generally harmless, it can occasionally cause discomfort through itchiness or dryness. The condition occurs when keratin—a protein naturally found in the skin’s outermost layer—becomes trapped within the hair follicle. This blockage prevents the hair from growing outwards, resulting in the characteristic tiny bump over the follicle. Individuals primarily seek treatment to reduce its appearance.
Most prevalent in those with fair skin, Keratosis Pilaris can be exacerbated during winter due to drier atmospheric conditions, and it may also worsen during pregnancy owing to hormonal fluctuations. It commonly resolves on its own by early adulthood (around the early 30s). Although complete eradication can be challenging, a consistent management approach can significantly improve its appearance—with regular exfoliation being key.
Management Tips
Regular Exfoliation: Using a chemical exfoliator up to three times a week is recommended; over-exfoliating can inadvertently worsen the condition. Chemical exfoliators are generally gentler than physical scrubs, as they utilise acids and enzymes to dissolve dead skin cells without manual abrasion. Look for formulations containing ingredients such as salicylic acid, glycolic acid, or lactic acid in cleansers, serums, or lotions. These help to effectively remove keratin blockages from the follicle while alleviating inflammation. Apply directly to affected areas two to three times weekly to reduce bumpiness, smooth, and soften the skin.
Thoughtful Shaving Practices: It is advisable to avoid using shampoo or body wash as substitutes for shaving cream. Shaving can heighten Keratosis Pilaris by irritating the skin, so opting for a product specifically designed for shaving is crucial. Non-foaming and unscented shaving creams or oils are less likely to cause aggravation.
