Resumen

Objectives: Acne represents a chronic inflammatory skin disease, with a peak incidence in adolescence and a form of ,, epidemic adult acne,, in the last decades. Acne represents a critical issue for public health, both of its negative impact on quality of life and its implication on antibiotic resistance. The main factors involved in acne are represented by hypersecretion of sebum and hyperkeratinization of the hair follicle, infection with Cutibacterium Acnes (also known as Propionibacterium acnes), and inflammation. Introduction: Because acne is a chronic disease, we need both an attack treatment and a maintenance treatment. The management plan must address all issues involved in acne – diet and skin care (including sun protection), local and general treatment, and laser and surgery. Also, is essential to break the myths associated with this disease and start the treatment as soon as possible to improve the quality of life and reduce the risk of scars, both physical and psychological. Materials / method: The possibilities of laser treatment for acne are based on the main mechanisms of the disease (pilosebaceous unit, infection with Cutibacterium acnes, and inflammation). The ideal treatment for acne must respect the following points: treat the,, cause,, and treat the entirely pathogenic chain, long-term effects (if possible to cure) and side effects zero (or at least mild), no pain, and simultaneous treatment of different pathogenic mechanisms. Results: The effects of QS Pulse Dye Laser are based both on the specific,,targets,, for nanoseconds pulse duration and the effects of 595 nm wavelength on hemoglobin and vessels. We present a series of cases of both active acne and erythema post-acne treated with QS PDL, with a specific protocol – 5 treatment sessions – 30 minutes, at two weeks, with no other local and general treatment, and a specific diet (no milk and high glycemic load food) and adapted skin care. The treatment was performed without pain during the treatment, with mild erythema post-treatment (which fades very fast). Conclusion: All patients show good response at treatment, with clinical improvement on both active lesions and erythema post-acne and the reduction of new lesions. In our opinion, QS PDL represents a new tool for the management of active acne and erythema post-acne, and is possible to integrate laser treatment with other options in acne management.
