PicoPlus
ข้อมูลจำเพาะหลัก
- Picosecond pulse duration (~450 ps) — shorter than the thermal relaxation time of melanosomes
- Energy converts primarily into a photomechanical (photoacoustic) shockwave rather than heat
- Shockwave fractures melanin into sub-micron particles cleared by macrophages, with significantly less collateral thermal injury than nanosecond Q-switched lasers
- Thermal-sparing profile makes it preferred for darker (Fitzpatrick III–V) skin where PIH risk is elevated
- Wavelengths used at Delight
- 532 nm (superficial pigment — freckles, lentigines), 1064 nm (Asian-skin-safe melasma toning + dermal pigment), 660 nm and 595 nm available for tattoo and ABNOM
- Typical session
- 10–15 min for face spots; 20–30 min for tattoo work
- Topical anesthesia not required for spot treatment
- Repeat
- 5–10 sessions for melasma protocols at 2–4 week intervals
