APPLICATION OF ND: YAG 1064NM LASER PLATFORMS VS INTENSE PULSED LIGHT IN THE TREATMENT OF FACIAL ACNE

Abstract

Acne is an inflammatory disease that affects the functionality of the sebaceous gland with hypersecretion of sebum and accumulation of epithelial cells, creating the right environment for the Cutibacterium acnes bacterium to proliferate. The presentation form of Acne can be with inflammatory and non-inflammatory lesions that can leave scars and permanent hyperpigmentation on the skin. As treatment alternatives, the use of light platforms has been proposed to inactivate the pathogen, reduce the hyperreactivity of the pilosebaceous unit, and improve the appearance of the skin. The aim of this study is to determine the effectiveness of the IPL and Nd: YAG 1064nm laser technology platforms in the treatment of facial acne in patients who have undergone various oral and topical dermatological treatments without favorable responses. The study was conducted in 4 patients randomly divided into two groups: Group A with 2 patients treated with Nd: YAG laser, and Group B composed of 2 patients treated with intense pulsed light (IPL) in a weekly session for 3 weeks. The results showed that treatment with 1064nm Nd: YAG laser improved both inflammatory and comedogenic lesions, while IPL reduced inflammatory ones. Both platforms improved skin texture and reduced sebaceous hypersecretion. In terms of side effects, pain improved as treatment progressed and erythema was minimal or absent. When evaluating the therapeutic effect, a better response was observed in patients treated with 1064nm Nd: YAG laser with a decrease in inflammatory and comedogenic lesions, as well as the degree of severity. The results of this research together with the recommendations provided allow the treating professionals to select the most appropriate treatment for their patients.
