What is Keratosis Pilaris?

Keratosis pilaris happens when keratin, a protein that protects the skin, builds up and plugs the openings of hair follicles. This creates tiny, rough bumps that may be skin-colored, red or brownish, sometimes with redness around each follicle. It often starts in childhood, may become more noticeable during adolescence, and tends to worsen in dry, cold weather. It is closely associated with dry skin and eczema and often runs in families. Although it is not harmful, it can be long-lasting and bothersome.

Who it's for

You may benefit from treatment if you have:

• Small, rough bumps on the backs of the upper arms or thighs
• Redness or brownish dots around hair follicles
• Rough, dry skin that feels like sandpaper
• Redness and bumps on the cheeks
• Bumps that worsen in winter or with dry skin

How we treat it at Egg Clinic

A dermatologist examines the skin to confirm keratosis pilaris and rule out similar conditions such as folliculitis or acne. Because it is chronic, the goal is to smooth texture and reduce redness over time.

The foundation of treatment is topical care: moisturizers containing urea, lactic acid or salicylic acid to soften keratin plugs, and in some cases prescription retinoids. In-clinic options can include chemical peels to exfoliate the plugged follicles. For persistent redness around follicles, vascular laser or light such as Excel V may help reduce the red appearance. When bumps and pigment are prominent, laser options targeting texture and follicles may be discussed. Your physician will choose settings suited to your skin type.

What to expect

After your consultation, in-clinic treatments usually take about 15 to 30 minutes. Peels may cause brief tingling, and laser sessions feel like quick warm snaps. Mild redness, dryness or flaking can follow for about a day or a few days. Improvement is gradual, typically after several sessions spaced two to four weeks apart, alongside daily home care. Keratosis pilaris often returns if care stops, so ongoing moisturizing is key. Results vary.

Aftercare

• Moisturize at least twice a day, ideally right after bathing
• Use lukewarm rather than hot water and limit long showers
• Avoid harsh scrubbing, which can increase redness
• Apply sunscreen on treated areas
• Skip saunas and strenuous exercise for a day after laser treatment
• Continue prescribed topicals as directed to maintain results

Frequently asked questions

Will keratosis pilaris go away?

It often improves with age, but it can persist for years. Treatment may help smooth skin and reduce redness, while ongoing care helps maintain results.

Should I scrub the bumps off?

Aggressive scrubbing can irritate the skin and worsen redness. Gentle chemical exfoliants and moisturizers are usually more helpful.

Is keratosis pilaris contagious?

No. It is a genetic, non-infectious skin condition.
