Applications

The manual splits the intended use into endogenous and exogenous pigment. Endogenous targets include birthmarks, pigmented nevi, cafe-au-lait spots, age spots and freckles. Exogenous targets include tattoo ink of various colours, as well as eyebrow, eyeliner and lip-line work, and traumatic tattoos. Wavelengths are assigned as follows.

• 532 nm: epidermal pigment such as freckles, solar lentigo and epidermal melasma; mainly red and brown ink.
• 1064 nm: tattoo removal, dermal pigmentation, and conditions such as nevus of Ota and Hori's nevus; mainly black and blue ink.
• 1320 nm: skin rejuvenation - a more even tone and a finer look to the pores.

The table below comes from the treatment-parameter sheet. These are the factory program defaults for frequency and energy, not a prescription. The operator sets the actual parameters for the skin and the target. The before-and-after panel is taken from the SQ-1 user manual; results vary.
