Clinical synopsis:
21 subjects, (38% male, 62% female, age range 14-21 years old) Burton grades III – IV were recruited. Each subject received alternate exposures to blue light, 20-minute duration and red light, 30 minute duration, twice weekly, (2-3 days interval between blue and red light treatments) for a period of 4 weeks (total 8 treatments). The unit was operated by the subjects during the treatment period and held in contact with the treatment area.

Results
Significant reductions in inflamed lesions were noted from week 4 onwards, with a final average reduction of 69% seen at the week 12 assessment (p>0.001). However the difference from baseline was significant as early as the second assessment at week 4. 74% rated the product very easy or extremely easy to use. Only 2 subjects, (11%) rated the product as only slightly easy. No subject rated the product as difficult to use.

Conclusion
This study has successfully demonstrated the use of a handheld LED device for the treatment of inflammatory acne. A significant reduction in acne lesions was seen from baseline to final assessment at week 12. The light treatments were well received by subjects, 69% reporting moderate to marked improvement at final follow-up. None of the included subjects reported their acne to be ‘worse’ or even ‘unchanged’ post light-treatment.
