In Southern Europe, there have always been many people with Fitzpatrick skin types IV – VI. In Northern Europe, this percentage ranges from nearly 30% in Belgium to around 20% in Switzerland and the Netherlands (Bataille et al, 2005). Combine this with increased average income and immigration and you’ll get our point. The demand for skin of colour laser treatments is on the rise.
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:7,8
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.5 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.5 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.6
