Clinical Indications of Q-Switched Laser
Through Q-switch technology, high peak energy pulses are released within nanosecond time frames, generating a pigment-selective destruction mechanism primarily driven by photoacoustic effects.
1064 nm — Deep Melanin — Nevus of Ota, Dark Tattoos
532 nm — Superficial Pigmentation — Freckles, Solar Lentigines
755 nm — Melanin — Café-au-lait Macules
What Indications Can Be Treated?
One Platform, Multiple Indications
1064 nm — Deep Dermal Pigmentation
Penetrates deeper into the dermis with relatively low epidermal melanin absorption.
Indications include:
Nevus of Ota
Acquired dermal melanocytosis
Deep tattoo pigments (black, dark blue)
Post-inflammatory hyperpigmentation (selected cases)
532 nm — Superficial Epidermal Pigmentation
Higher absorption by melanin and hemoglobin, with shallower penetration depth.
Indications include:
Freckles
Solar lentigines
Epidermal pigmentation
Red/orange tattoo pigments
755 nm — Refractory Pigmentation
Higher melanin absorption coefficient compared to 1064 nm, effective for resistant pigment particles.
Indications include:
Stubborn tattoo ink
Certain café-au-lait macules
Resistant mixed pigmentation
Clinical Indications of Q-Switched Laser
Pigmentary Lesions:
Melasma, freckles, sun spots
Age spots, café-au-lait spots
Nevus of Ota, congenital nevi, Mongolian spots
Tattoo Removal:
Black, blue, red, green, and multi-color tattoos (effect depends on wavelength)
Other Applications:
Adjunct in fractional or combined laser treatments for post-inflammatory hyperpigmentation
Specific pigmented acne scars
