Laser toning
Low-fluence laser toning for dullness and pigment, usually sold as a course.
Laser toning uses low-energy passes, often with a Q-switched Nd:YAG laser, to brighten dull or uneven skin. Clinics in Seoul in particular sell it as a course of many short visits rather than one strong session.
It shows up in melasma plans next to pico laser. They are not priced on the same unit. Toning quotes are often per session inside a package of ten or more.
Downtime
Most people leave pink and go back to the day. The risk with very frequent toning is irritation and, for some skin, darker patches. That is a reason to know who is choosing the settings.
