TREATMENT TECHNIQUE – 532 NM OTHER WITH COOLVIEW HANDPIECE
• WARNING: The red diode aiming beam in the sapphire window should be in full contact with the skin before,
during, and after the laser pulse.
o Pay close attention when treating over the nose or curved areas to ensure full contact with the window
where the red aiming beam is present.
o Consider using a smaller spot size if you cannot ensure full contact with the sapphire window.
• Apply a thin layer of clear gel (such as ultrasound gel) for increased epidermal protection and patient
comfort.
• Ensure that there are no large air bubbles underneath the sapphire window.
• Always observe the epidermis during the treatment, watching for signs of damage (blanching or gray
coloration).
o If damage is seen, stop the treatment and apply a cool compress and evaluate the area for possible
complications and wound care.
Scar Treatments
• Only one pass is recommended.
• 3+ treatments spaced 4 weeks apart are recommended.
• Treat to the minimal clinical response.
• Common endpoints are momentary flush or a slight blue tinged in the vessels.
o Minimal change or even temporary change in color is expected.
o Never double-pulse, even if clinical endpoint is not seen.
Bruising
• Ideally, treatment should be performed soon after the bruise is stabilized (typically 24
-36+ hours) and well
before yellowing.
o 18
-24 hours for superficial bruises
o 36+ hours for traumatic bruises
• Double-pass using a basket-weave pattern recommended for lighter bruises with less target.
• One pass recommended for darker bruises with more target.
• The endpoint is typically not visible.
o There may be a softening of the bruise color immediately post-treatment.
• The bruise will typically begin to fade within a few hours after treatment.
