PolarisPolaris
• Based on ELOS technology– Conducted RF
– High power diode laser
– Effective cooling
• Multiple applications– Wrinkle and skin texture
treatment (WR)
– Leg vein treatment (LV)

WR Applicator designWR Applicator design
• Electrode design allows high energy delivery to a depth of 2.5mm
• Light energy is absorbed by micro-vascularities creating heat which focuses the RF at the center of the target tissue
Polaris WRPolaris WR
• High power conductive RF – Energy - up to 100J/cm3
• Unique diode laser– Wavelength - 900nm – Fluence - up to 50J/cm2
• Effective cooling – Temperature - 2oC
WR mechanism of collagen WR mechanism of collagen remodeling - preremodeling - pre
• Collagen is normally densely packed and relatively inactive in mature skin.
• Interfibrillar spacing this compact limits blood supply to the area inhibiting the formation of new fibres
WR mechanism of collagen WR mechanism of collagen remodelling – immediately postremodelling – immediately post
• The WR treatment creates a deep oedema. This swelling allows lymphatic and vascular drainage in the dermis.
• Intrafibrillar spacing is increased .• Fibres are separated and oriented chaotically• Oedema and erythema appear on the skin surface
WR mechanism of collagen WR mechanism of collagen remodelling – remodelling – 3 weeks post treatment3 weeks post treatment
• After oedema has resolved, the collagen maintains the intrafibrillar spacing.• Collagen neogenesis stimulated by WR treatment fills the spaces with new fibres,
resulting in dermal remodelling.• Seen clinically as “tightening” and deep wrinkle reduction.

Polaris LV– Vascular TreatmentsPolaris LV– Vascular Treatments
• Polaris LV (leg veins).
• Effective for all colours of leg veins up to 5mm diameter.
• Low treatment pain levels.
• No late burning.
Polaris LVPolaris LV
• Concentrated conductive RF – Energy - up to 100 J/cm3
• High power diode laser– Wavelength - 900nm – Fluence - up to 140J/cm2
• Effective cooling – Temperature - 2oC
Main requirements to leg vein Main requirements to leg vein treatmenttreatment
• High energy penetration depth (>2mm).
• High energy density on treated vein (>100J/cm2).
• Strong absorption of energy by haemoglobin.
• Epidermal cooling.
LV Applicator designLV Applicator design
• Electrode design: – allows high energy
delivery to the deep dermis.
• Light energy:– generated at the peak
of haemoglobin absorption.

Polaris LV – working principlesPolaris LV – working principles
1. Place probe on skin over vessel.
2. Light is selectively absorbed by blood.
3. RF goes through the pre-heated vessel
4. RF and light combination creates coagulation of vessel wall
