Brief Summary

The purpose of this study is to determine whether low level laser light therapy is effective in the treatment of acne blemishes.

Detailed Description

Acne is a chronic inflammatory disorder plaguing the sebaceous follicle, and debate still remains over what truly initiates lesion formation. Experts agree that an increase in androgen production plays a significant role in the onset of acne. Androgens promote the increase in size of sebaceous glands and stimulate sebum production. The simple act of sebaceous gland stimulation via androgens could ultimately promote the upregulation of pro-inflammatory cytokines like tumor necrosis factor-α (TNF-α) and interleukin (IL-1α) without propionibacteria even being present. The synthesis of IL-α and other pro-inflammatory cytokines including prostaglandins occurs via the inducible enzyme known as cyclooxygenase-2 (COX-2). Studies analyzing the pathogenesis of mucositis have identified COX-2 as an important contributor to the upregulation of pro-inflammatory cytokines and thus a major contributor to the progression of the disorder itself.

Recent evidence indicates that low-level laser therapy (LLLT) is able to significantly diminish the expression of COX-2, resulting in the reduction of inflammation. The ability to modulate the COX-2 pathways via LLLT is believed to inhibit the production of pro-inflammatory cytokines (i.e. TNF-α and IL- α) present in acne-prone skin.

Study Groups

Erchonia MLS + Erchonia THL

The Erchonia® MLS contains 5 independent diodes: 4 each emitting 17 milliwatt (mW) 635 nanometers (nm) of red laser light and the fifth diode emitting 17 mW, 405 nm of blue laser light.

The Erchonia THL is a single diode pulsed laser that emits 4.9 milliwatts (mW) of red 635 nanometer (nm) light.

Group Type: EXPERIMENTAL

Erchonia MLS + Erchonia THL

Intervention Type: DEVICE

The Erchonia® MLS is administered weekly for 6 continuous weeks at the test site by the study investigator.

The Erchonia THL is administered twice daily for 6 continuous weeks (42 days) at home by the subject.

Administration of the MLS and the THL occur simultaneously over the 6-week administration phase.

The intent is to evaluate the effectiveness of Erchonia MLS & Erchonia THL when administered together, and not to compare Erchonia MLS vs. Erchonia THL
