Brief Summary:
This is a Multi-center, blinded, baseline-controlled, prospective study to evaluate permanent hair reduction and removal for skin types V and VI using IPL.

Condition or disease Intervention/treatment Phase
Removal of Excess or Unwanted Body Hair Device: Treatment group Other: No intervention Not Applicable

Detailed Description:

One hundred and twenty (120) subjects who are Fitzpatrick Skin Type V-VI, and have a suitable treatment area for hair removal will be evaluated in this study.

Each subject will receive six treatments at four to six week intervals upon re-growth of hair and return for follow-up visits at one, three and six months after the last treatment.

Measurement Equipment Standard High Resolution Digital Camera

Labels for hair count Customized hair count sticker templates will be placed directly on the skin and the hairs in this window will be counted at specific visits during the study as detailed in section.

Study Procedures Each subject will participate in the study for a period of at least 11 months. The study is anticipated to be completed within twelve months.

Test spots Up to 3 test spots will be performed in the selected treatment area to determine the optimal parameters / setting.


The treatment areas are divided into 3 groups. Each Subjects will be allocated to one of the following groups::

  • Two small anatomical areas (right and left axillae and double sided bikini line) or;
  • One double sided large area (right and left thighs) or;
  • One large area (whole back / abdomen)

Based on the mild nature of treatment, anesthesia is not required. Before starting treatment apply a layer of conductive gel to the treatment area.

After applying the conductive gel, locate the applicator in close contact, perpendicular to the skin with no pressure applied. Pressing the applicator will fire the IPL pulse. In order to ensure full coverage of the treatment area applicator placement should overlap approximately 1/3 of the previously treated skin.

Post-treatment Instructions Cold packs may be placed on the treated area for post treatment cooling. Subjects should be aware that post treatment erythema, edema and some discomfort of the treated areas are possible and should not be a cause for concern. They may also experience some purpura in the treated areas which would be expected to resolve within several days.

Arm Intervention/treatment
Experimental: Treatment Group
Hair removal treatment using Venus Versa IPL energy
Device: Treatment group
The intense pulsed light (IPL) applicator with a wavelength of 690 nm and spot size (treatment area) of 30 mm by 10 mm will be used to deliver the energy to the treatment area.

Other: No intervention
Subject will act as their own control where the baseline hair count will be used as a comparator to the hair count after treatment.

Placebo Comparator: No intervention
Subject hair count at baseline will act as the control to which the hair count at 6 months after the last treatment.
Other: No intervention
Subject will act as their own control where the baseline hair count will be used as a comparator to the hair count after treatment.

Primary Outcome Measures :
  1. Hair Count 6 Months Following Last Treatment [ Time Frame: 6 months after last treatment ]
    Hair count reduction in marked treatment area assessed from photographs taken 6 months following the last treatment as compared to photographs of the marked treatment area taken at baseline.
