Properties Of ELOSProperties Of ELOS
Well known in medicine Is not absorbed by melanin All RF parameters (Voltage, Current,
Impedance) are measured and controlled during the treatment. Examples:– Contact must be maintained with the skin or the
Aurora will not fire.– Skin impedance depends on temperature and can be
used for skin heating monitoring
RF Energy
Temperature Distribution Temperature Distribution “RF Heating”“RF Heating”
RF creates heat in the 30 micron layer of the follicle that surrounds the hair shaft
Heated layer includes hair follicle and bulge
Follicle Shaft
Properties Of ELOSProperties Of ELOS
Light pulse pre-heats the tissue and the target* (*vein, pigmented lesion or hair shaft)
A Higher Temperature in the target area will lower the impedance of the target area.– Lower impedance provides an easier path for electrical
energy to flow
Light energy
Temperature Distribution Temperature Distribution “Optical Heating”“Optical Heating”
Light heats hair shaft through selective photothermolysis
Bulge and follicle are damaged due to heat transfer from hair shaft
Surrounding tissue temperature is passively increased
ShaftFollicle
Temperature Distribution - Combination Of Temperature Distribution - Combination Of
“Optical Heating” And “RF Heating”“Optical Heating” And “RF Heating”
Combination of two types of energy create uniform heating in the shaft and follicle
Properties of ELOSProperties of ELOS
The Active Cooling in the Aurora DS handpiece, increases the impedance of the epidermis making it resistant to RF heating.
The Cooling also provides additional comfort to the patient

RF Pulse DistributionRF Pulse Distribution
1. RF energy distribution is dictated by the impedance distribution within the tissue.
– Tissue with low impedance (warm temperature) conducts higher RF current
– Tissue with high impedance (cold temperature) conducts lower RF current.
RF Pulse DistributionRF Pulse Distribution
1. Cooling the epidermis raises the impedance on the surface forcing the RF under the epidermis.
The result:
–Less heating in the epidermis –Greater efficacy and energy efficiency–Greater safety

Phase 3 Of StudyPhase 3 Of Study Investigation of exact therapeutic benefits and advantages of
the Aurora DSR device for Photo- rejuvenation
Photo- rejuvenation and collagen repair or shrinkage have precise spatial and temperature relationships
The nature and spatial configuration of RF energy and the way it radiates through the skin make it especially suited to PR by modifying collagen shrinkage and fibroblast proliferation
The optical energy is especially suited for its effects on epidermal pigmentation and micro- vasculature
