Which laser tames 'Chicken Skin'? a Head-to-Head test
NCT ID NCT07739420
First seen Jul 31, 2026 · Last updated Jul 31, 2026
Summary
This trial compares two types of lasers—fractional carbon dioxide and long-pulsed Nd:YAG—to see which works better for keratosis pilaris, the rough bumps often called 'chicken skin.' People aged 13 and older with keratosis pilaris on both upper arms will receive each laser on a different arm, allowing a direct comparison. The study measures skin improvement, pain during treatment, and overall satisfaction.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Fractional carbon dioxide laser and long-pulsed 1064 nm Nd:YAG laser
- What this could lead to
- If one laser proves more effective, it could offer a clearer treatment option for keratosis pilaris, reducing the rough bumps and redness on the skin.
- What could go wrong
- This is a small study with only 27 participants, so results may not apply to everyone. Lasers can cause pain, redness, or pigmentation changes, and the condition may not improve significantly.
