diode laser hair removal
In order to safely and effectively heat the hair shaft and damage the surrounding cellular structure in the follicle, the device used should have the following characteristics:
(i) Wavelength selectivity: Light absorption by the hair shaft should be higher than the surrounding tissue.
(ii) Pulse duration of the light/laser should be shorter than the hair structure thermal relaxation time.
(iii) Light penetration into the skin has to be deep enough to absorb even in the deepest part of the hair follicle. Depth of penetration is usually better with longer wavelengths and larger spot sizes.
Most of the physician in-office lasers and IPL systems can accomplish permanent reduction and long term hair clearance, prolongation of the Anagen-Telogen cycles, micronization of the remaining hair

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.
Table 1 shows hair reduction by treatment sites.
| # of Subjects | Hair clearance % |
Bikini line | 98 | 68.6 |
Axilla | 79 | 65.3 |
Lower legs | 85 | 78.5 |
Arms | 38 | 73.8 |

All of study subjects experienced hair clearance at the 12 months follow up session.
