Abstract

Acne is one of the most common skin diseases today and leaves a bad influence on the psychology of the patient because of scars and permanent deformation on the skin. Low-level laser phototherapy methods have been proposed for research in the treatment of acne. This paper investigates the inhibitory ability of blue laser (532nm) at a power of 5mW lighting directly on petri dishes with C. acnes – causing acne vulgaris. Our team conduct the survey in 3 exposures 48 hours apart with 4 times intervals (5 minutes - 10 minutes - 20 minutes - 30 minutes) to find the most suitable course of treatment. With the results of the number of bacteria that obtained on the surface of the petri, exposes 3 irradiations for 30 minutes, it reduced by 82% compared to the sample. Therefore, the result indicate that this is the most effective period to achieve treatment for a course of 3 times irradiate 48-hour-period.

Keyphrases: acnes, c. acnes, low level laser
