Laser hair removal works by targeting areas with specific chromophores – in this case, the melanin found in the hair (See previous section for a description of chromophores). The patient should be followed up in 2-4 weeks as needed. The practitioner chooses the wavelength to utilize based on the target or chromophore they are treating. The length of hair growth cycles vary for different body parts. Long-pulse ruby (694 nm), long-pulse alexandrite (755 nm), long-pulse diode (810 nm), longpulse Nd:YAG (1,064 nm), and intense pulsed light (IPL) (590-1200 nm) destroy hair photothermally by emitting wavelengths within this range. The results can be better if we do subcission of bigger scars and do chemical peeling 3 or 4 times before the laser treatment. Treatment parameters for Vascular lesions using long pulsed Nd YAG Laser, Telangiectasia  - Spider vein Common areas to treat are the face, chest, legs, arms, underarms and bikini line. The fluence (J/cm2) determines the temperature achieved within the follicular stem cells in the bulge while the pulse duration corresponds to the time length of that reached temperature. When these endpoints are met, you obtained proper … Beijing Superlaser Technology Co.,Ltd. I am between 3-4 skin type but closer to 3.

Laser hair removal is a cosmetic procedure that uses a powerful laser or intense pulsed light (IPL) to remove unwanted hair. Epidermal cooling is another factor that allows higher fluences and thereby reducing the pain and side effects in darker skin. Laser parameters that affect results Several wavelengths of laser energy have been used for hair removal, from visible light to near-infrared radiation. And spot size, the laser … These include vaporization or singeing of the hair (did you see and smell it burn), and peri-follicular erythema and edema (swelling and redness around the follicle after the treatment, which typically lasts a few hours). It can be helpful for women with excessive hair growth (hirsutism). CONCLUSION: The long-pulsed Nd:YAG laser is a safe and effective method of hair removal.
