[show abstract][hide abstract] ABSTRACT: This study was an evaluation of self-applied, blue light, light-emitting diode therapy in the treatment of mild-to-moderate inflammatory acne on the face and associated labeling to determine if subjects are capable of self diagnosing their condition and whether they are capable of self-administrating treatment. Subjects included had no prior experience with the device. They were given the device and a copy of the labeling. Based on their own assessment, they were evaluated for their comprehension of the device and for its intended use. The study, which comprised 18 females and three males with an average age of 31, demonstrated that all participants (100%) were capable of correctly identifying their acne condition. The labeling, which was key to educating users in recognizing their acne type, included clear descriptions of different categories of acne. The study also demonstrated that the user was capable of self administering the treatment based solely on the device's labeling and without the supervision of a medical doctor.

[show abstract][hide abstract] ABSTRACT: This study was an evaluation of the performance of self-applied, blue light, light-emitting diode therapy in the treatment of mild-to-moderate inflammatory acne on the face, concerning: 1) time to improvement and/or resolution of the number of blemishes and lesions on the face; 2) quality of skin condition; 3) occurrence and count of the number of new blemishes and lesions; and 4) ease of product use; patient comfort, wellbeing, and satisfaction during the treatment period; and safety of treatment. Subjects (N=21) were included according to the inclusion/exclusion criteria and after they had given informed consent. The blue light treatment was conducted over an eight-week period. For study data management and analysis, SPSS 16.0 statistical software was used. Data management and analysis was performed independently using, where appropriate, ANOVA, student t-test, and Mann-Whitney test for N=20. Tests were carried out at the five-percent significance level. The confidence interval was 95 percent. Twenty-one subjects concluded the study (18/21 were female and 3/21 were male). Upon the first outbreak of acne, subjects had a mean age of 15 years (range 8-28 years), and 19 subjects had mild-to-moderate acne for a mean duration of 13.1 years. During the study period with self-applied blue light treatment, the total number of comedones on the face had significantly reduced for the assessment at Day 7 (p<0.019) and at Day 28 (p<0.001). The total number of open comedones (blackheads) on the face during the treatment period was reduced significantly (p<0.02) for assessment at treatment Day 7 (p<0.005) and for the assessment at Day 28. The total number of closed comedones (whiteheads) on the face during the treatment period, was reduced significantly (p<0.007) for the assessment at Day 28. The total number of papules during treatment had reduced significantly for assessment at Day 7 (p<0.048) and Day 28 (p<0.005). The total number of pustules during treatment had reduced, but this difference was not statistically significant. This was similar for nodules present. Subjects expressed confidence in using the self-applied blue light without the supervision of a doctor. Regarding previous treatments, subjects expressed dissatisfaction and considered self-applied blue light treatment to be better for their condition. Self-applied blue light treatment was reported to be easy and safe to use.
