Picosure εναντίον Picoway: Κατανόηση των λέιζερ Picosecond στη μελάγχρωση και την αναζωογόνηση του δέρματος

Εισαγωγή

Τα τελευταία χρόνια, picosecond lasers have become one of the most sought-after technologies in aesthetic medicine, especially for pigmentation, melasma, tattoo removal, and overall skin rejuvenation. While both Picosure and Picoway belong to the family of Q-switched picosecond lasers, they differ in wavelength, pulse duration, handpiece design, and clinical applications.

This article compares Picosure (755nm) and Picoway (532/730/785/1064nm) to help practitioners, clinics, and distributors better understand their mechanisms, treatment advantages, and how to choose the right device for patient needs.

What Makes Picosecond Lasers Different?

Traditional Q-switched nanosecond lasers rely mainly on photothermal effects, which can cause collateral tissue damage and post-inflammatory hyperpigmentation. Picosecond lasers, with a shorter pulse width (ps vs. ns), deliver more photomechanical shockwaves instead of heat.

• Shorter pulse duration = stronger photoacoustic effect
• Result: Melanin is shattered into finer particles, which are more easily cleared by macrophages.
• Benefit: Less heat damage, reduced downtime, and fewer side effects.

1. Ενωσία (755nm)

Βασικά Χαρακτηριστικά

• Μήκος κύματος: 755nm Alexandrite, highly absorbed by melanin, low absorption in water and hemoglobin → safer for surrounding tissues.
• Διάρκεια παλμού: 550–750ps.
• Χειροκίνητα:
  • Ανίπταμαι διαγωνίως: 2–6mm adjustable spot size.
  • Fixed: 6mm, 8mm, 10mm.
  • Focus Lens Array (honeycomb): increases peak power 20x for skin rejuvenation.
• Modes:
  1. Whitening mode (large spot, uniform toning).
  2. Focus Lens Array mode (fractional rejuvenation, collagen stimulation).
  3. Pigment/tattoo removal mode (small spot, high power).

Clinical Advantages

• Gold standard for melanin-targeting (freckles, sun spots, melasma).
• Unique Focus Lens technology improves fine lines, pores, and redness.
• Strong collagen stimulation due to partial photothermal effect → better skin rejuvenation.
• Trade-off: Slightly more painful, with longer recovery compared to Picoway.

2. Picoway (532nm, 785nm, 1064nm)

Βασικά Χαρακτηριστικά

• Μήκη κύματος:
  • 532nm – superficial pigmentation (freckles, sun spots), red/yellow tattoos.
  • 1064nm – deeper pigmentation (Ota nevus, dermal melasma), black tattoos.
  • 730nm – resistant green/blue tattoos, mixed pigmentation.
  • 785nm – alternative for dermal pigmentation.
• Διάρκεια παλμού: 300–450ps (shorter than Picosure).
• Χειροκίνητα & Modes:
  • Zoom handpieces: for pigment and tattoo removal.
  • Resolve handpieces: fractional rejuvenation, collagen induction via laser-induced optical breakdown (LOB).

Clinical Advantages

• Multi-wavelength versatility → broader range of indications (multi-color tattoos, deeper dermal lesions).
• Stronger photoacoustic effect → less heat, shorter downtime.
• Resolve mode triggers dermal repair, collagen production, pore reduction, wrinkle improvement.
• Trade-off: Less melanin-specific absorption compared to Picosure 755nm.

Choosing Between Picosure and Picoway

Picosure (755nm)

✔ Best for melanin-related pigmentation (melasma, freckles, sun spots).
✔ Unique Focus Lens → strong rejuvenation benefits.
✔ More effective for stubborn pigmentation.
⚠ More discomfort, slightly longer downtime.

Picoway (532/730/1064nm)

✔ Multi-wavelength versatility → excellent for multi-color tattoos + deep dermal pigmentation.
✔ Strong photoacoustic effect → gentler on skin, faster recovery.
✔ Balanced rejuvenation results with less pain.
⚠ Less melanin-specific targeting compared to Picosure.

συμπέρασμα

Και οι δύο Picosure and Picoway are powerful συστήματα λέιζερ picosecond designed for pigmentation, tattoo removal, and skin rejuvenation.

• Ενωσία stands out for melanin-specific absorption and collagen-stimulating rejuvenation with its honeycomb Focus Lens.
• Picoway offers versatility with multiple wavelengths, stronger photoacoustic effect, and shorter recovery times.

👉 For clinics, the choice depends on patient demographics:

• If your focus is Asian skin types with melasma and pigmentation, Picosure may deliver superior results.
• If your practice handles tattoo removal and diverse pigmentation types, Picoway provides broader versatility.

Ultimately, the most effective approach often combines device selection + individualized treatment protocols, ensuring safe, precise, and long-lasting outcomes.
