A New Treatment for Patients Affected by Keratosis Pilaris

Sometimes called “Chicken Skin," Keratosis Pilaris is a common condition leading to the formation of rough, dry patches on the skin. Tiny bumps on the skin are caused by dead skin cells that block hair follicles. This study demonstrated improvement, on the laser-treated side, in redness and prominent improvements in perifollicular erythema and upper arm cherry hemangioma under dermoscopic examination. The reduced follicular plugs and perifollicular inflammation were histologically in line with the disappeared or reduced hair shafts and erythema under dermoscopy.

The findings signify that the 755-nm alexandrite laser offers an advantage over the 810-nm diode laser in redness improvement. The laser treatment was relatively safe and did not cause serious or unexpected adverse effects.

Compared with both fractional CO2 and Q-switched Nd:YAG (1064- nm) laser techniques, the GentleMax Pro^® 755-nm alexandrite laser is nonablative and is equipped with a cryogen spray cooling device, which greatly reduces the feeling of discomfort during treatment. Histopathological examination revealed thickened collagen and reduced inflammatory cell infiltration in the dermis, thereby establishing that a 755-nm alexandrite laser could penetrate the mid-dermis to induce regeneration and relieve the inflammation.
