Results

The device was simple to operate and ergonomically efficient. The patients perceived some very slight discomfort on emission of the light pulse, but none requested the treatment to be stopped nor asked for topical anesthetic cream. 

Immediate Response

The immediate cutaneous response from the Silk’n device was a mild peri-shaft erythema and perifollicular edema that appeared within 5-10 minutes. There was an immediate carbonization of the hair shaft and the aroma of thermal hair shaft coagulation.

Hair Clearance success

Hair clearances were calculated as the ratio between the hair count at the baseline taken before any treatment and the count taken at each follow up visit.

The overall hair reduction average was 71.2% for all patients in all areas.

The Silk’n™ Device Specifications

The Silk’n device is a small, portable, low cost, low energy HPL™ (Home Pulsed Light™) system with the following specifications:

       .  Wavelengths:  475nm-1200nm

       .   Max energy density:  5 J/cm2

       .   Spot Size:  20 X 30 mm2

       .   Pulse Rate:  1 pulse every 3.5 seconds

Materials and Methods

110 female subjects with average age of 32.4 yrs old enrolled to the study. All subjects were trained and performed the first treatment at the investigators office under the supervision of a trained laser nurse. Most common treatment sites were the Bikini (98), Axilla (79), Lower legs (85) Arms (38). Skin types ranged from type Fitzpatrick 1 (3), skin type 2 (43), skin type 3 (47) and skin type 4 (17).

Informed Consent was obtained by all study participants. The body sites that were to undergo the hair removal treatment were photographed. Standardized close up photographs were taken pre-treatment, and at the 12 months follow up session treatment. Hair count was preformed on 1 square inch from the before and after pictures.   

Conclusions

We have demonstrated in a large, randomized, blinded study the clinical efficacy and safety of the Silk’n Hair Removal Device. The Silk’n device was able to produce hair clearance results that rival in-office, high fluence, physician controlled “big box” laser hair removal devices.

The Silk’n device proved to be not only effective, but safe and relatively painless. The only post-treatment reaction that was observed in 25% of the patients was a peri-follicular erythema and edema that was self resolved within one hour.

The efficacy, safety profile, comfort, portability and ease of use of the device confirms the clinical and commercial viability of Home Pulsed Light hair removal, that is expected to alter how hair removal is conducted.
