I fully agree with Dr Chua. Picosecond laser treatments are generally pricier than Q-switched ND-YAG laser treatments.
In addition, Picosecond lasers can be used to treat more stubborn pigment disorders that do not respond well to Q-switched ND-YAG lasers alone.
In clinics that have both Picosecond and Q-switched ND-YAG lasers, doctors can tailor a treatment plan using these two lasers to treat stubborn pigment disorders whilst keeping treatment prices more affordable.
Do note that Lasers are tools for your doctor. You need good technology and a well-trained doctor to give you good results. Both are equally important!
