Conditions

Low Level Laser Therapy, Acne Vulgaris

Brief summary

The present study is designed to compare clinically the therapeutic applications between low level laser therapy (excimer laser) and non-laser polarized light (Bioptron prol) in the treatment of Acne vulgaris.

Detailed description

Traditional acne treatment often involves topical application, which can cause skin irritation and dryness, and oral antibiotic therapy, which is limited by antibiotic resistance. Newer procedures like laser and light-based therapies offer alternative treatments for patients who struggle with adherence or experience side effects or treatment failure. This study aims to compare the therapeutic application of laser and light therapies as an alternative to traditional acne treatments.

Interventions

Excimer laser patients undergo ultraviolet b phototherapy treatments at a physical medicine clinic twice a week for four weeks. The device uses a 308nm beam of coherent light, with six spot sizes to avoid healthy skin. The radiation exposure time is 10 minutes, with a maximum dose of 0.65 J/cm². Personal protection standards include wearing protective eyewear for the retina and choroid, as they absorb visible light radiation, which can cause keratoconjunctivitis or cataracts. The thermal effect of the laser can cause superficial carbonization of the epidermis, phlyctens, or erythema, so non-flammable gloves are recommended.

DEVICEBioptron Pro 1

Patients undergone Bioptron light treatment twice weekly for four weeks at a physical medicine clinic. The treatment is administered by a physiatrist following the manufacturer's user guide. Patients sit in a comfortable chair with their hand on an armrest, holding the Bioptron light probe at a 90° angle for 10 minutes.

Design outcomes

Primary

MeasureTime frameDescription
assessment of change of Global Assessment ScaleAt baseline and after 4 weeksFor the study, we recruited males and females with mild to moderate acne according to the Investigator's Global Assessment (IGA) scale, where the severity of acne and the type of lesions was assigned to it. the scoring ranges from 0 to 4. Zero indicates clear skin with no inflammatory and non- inflammatory lesions, while 4 indicates severe lesion with Many comedones and inflammatory lesions, ≤ several nodules and cysts

Secondary

MeasureTime frameDescription
assesment of change of digital facial photographsAt baseline and after 4 weeksDigital Facial photographs, included in the photographic documentation, were taken by (Nikon Camera), before the procedure and four weeks after the end of the whole therapy. Digital facial photographs will be taken for each patient at the base line and end of the fourth week to track the development of acne lesions and evaluate treatment effectiveness, using the same method for each patient.
