When you have plaque psoriasis on your feet, hands, elbows or legs, skin cells called keratinocytes grow faster than usual and have no time to develop properly. This is what causes the inflammation and scaly plaques on your skin. Treatment with blue light helps the skin to regenerate at normal speed again – controlling the inflammation and redness without chemicals or UV light.
Clinical studies have confirmed the positive effects of blue light on psoriasis plaques.1,2 In one study, patients who were treated for 12 weeks experienced significant improvements to their plaque symptoms. In some patients, the psoriasis plaque even cleared up completely. After the treatment, the patients were observed for another month. In this time, their plaque symptoms continued to improve slightly – even without performing the blue light treatment. 83% of the patients said that Philips BlueControl was very easy and convenient to use.2
