Treating skin of colour with lasers asks for special considerations.  
​有色肌膚(Fitzpatrick skin type IV,V,VI)的激光治療

It's well known that cosmetic treatments differ for patients with skin of colour. And, treating darker skin types with lasers has especially been a challenge. Some laser treatment considerations include:

眾所周知,有色肌膚的激光治療是非常有挑戰性的。需要特別考慮的因素有:

  • A wavelength that is specific to and well absorbed by the chromosphere being treated, good skin penetration, and preferential absorption of melanin. 特定的波長,能夠有效的穿過皮膚,被特定的色素顆粒吸收

  • A laser that doesn't overheat surrounding tissues. 激光不會過度的加熱周圍組織

  • A laser that offers highly customisable treatment parameters (adjustable power, spot size and fluence, no compromise of spot size for fluence). 激光可依據不同問題提供靈活的治療方案

  • A laser treatment that requires a small or reduced number of treatment sessions, relative to other laser treatment options, with minimal treatment time and low fluence. 和其他類型的激光相比較,治療次數相對減少,恢復時間短,較低的能量

 
 
 
 
 
 
 
 
 
 
 
The latest lasers, such as the PicoWay® system, open new doors. 最新的激光科技,皮秒激光,對有色肌膚的治療打開了一扇新的大門

 

Nanosecond lasers have restrictive use in skin of colour due to the significant risk of PIH. With QS lasers, skin of colour has a 25% risk of developing PIH. Risk is reported to increase to 47% when the treatment is specific for lentigines, possibly due to the melanocytic hyperplasia noted histologically in a lentigo. Picosecond lasers however can be used in a broader range of skin types than nanosecond lasers due to reduced risk of hyper- or hypopigmentation and scarring with picosecond photoacoustic versus photothermal effect. Shorter pulses and enhanced photoacoustic effect avoids overheating of skin and decreases risk of PIH. In skin of colour, a clinical study with the picosecond laser demonstrated a low rate of PIH, at only 4.65% of the lesions. 

納秒激光治療有色肌膚類型,長生返黑的機率非常高 (25%)。皮秒激光能夠用來治療更廣的皮膚類型,因為他的光速更快,長生更低的光熱效應,不會過度加熱周圍的皮膚,有效的降低了返黑和斑痕的產生。臨床研究證實,皮秒的返黑率只有4.65%。

What Can PicoWay Treat?  治療範圍

 

 

Acne Scars  痘痕

Did you know that nearly 40% of those with acne have some degree of scarring? Many acne scars result from a loss of collagen in the skin. PicoWay Resolve is an ultra-short, picosecond laser that reaches below the surface of the skin to stimulate production of collagen and elastin, without breaking the outermost layer of the skin. In clinical studies, 94% of treated areas improved and patients were highly satisfied with results.

 

 

Wrinkles  皺紋

Millions of people each year seek treatment for their wrinkles. Wrinkles can be caused by a loss of collagen and elastin in the skin.

PicoWay Resolve is a non-invasive, needle free treatment option for wrinkles. Resolve uses ultra-short laser pulses to reach under the skin, without breaking the outer layer of the skin. Picosecond lasers are proven to stimulate collagen and elastin.

 

 

Dark Spots 黑斑

Skin discoloration is common, yet treatable. Dark spots, or benign pigmented lesions, such as freckles, liver spots (age spots), and café-au-lait (brown patches), appear in many people on different areas of the skin. Some spots are related to excessive sun exposure. Others, like melasma, can be caused by hormone changes, often impacting women following pregnancy. Many of these skin discolorations can be distressing and affect quality of life.

 

 

Tattoo Removal  刺青移除

PicoWay is a high power lower with ultra short pulses that shatters tattoo ink, but leaves the outer layer of the skin intact. PicoWay treats a wide range of tattoo colors across a broad range of skin types. Over a series of brief treatments, PicoWay can eliminate most tattoos. That’s why PicoWay is the tattoo removal laser of choice by the nation’s leading tattoo removal provider network, Invisible Ink Tattoo Removers.
