4. Existing technology for selective photothermolysis
Optical energy: penetrating into the skin and selectively absorbed by the target
Lasers - monochromatic light
IPL produces broad spectrum of light
Electrolysis basing on delivery of RF energy to the hair root by insertion of needle to each follicle (Thermolysis)
ThermaCool By Thermage (RF) –unipolar system for wrinkle treatment
Proprietary Information of
AMA

5. Light-based Hair removal_ +
Strong absorption by dark hair shaft
Penetration depth of a few millimeters
High selectivity between hair shaft and dermis
High efficiency for dark hair and light skin
Hair chromophore melanin - the same as of epidermis
Dark epidermis has higher risk of damage
Treatment of light hair is not effective
Does not effect hair follicle and buldge directly
Indeterminacy of light effect because of its scattering and reflection

8. Syneron ELOS Technology
Two types of energies sources with different selectivity mechanism
Optical energy: absorbed in the target by the right choice of wavelength and pulse duration
Electrical RF energy: Chromophore independent not sensitive to skin or target color!
Proprietary Information of
AMA

9. Syneron ELOS Technology
Reduce the optical energy to a safe level for all skin types
Compensate for the lack of optical energy with electrical RF energy that is not sensitive to skin or target color

Proprietary Information of
AMA

12. Proprietary Information of
RF energy properties
Well known in medicine
Does not effect the melanin
All RF parameters (Voltage, Current, Impedance) can be measured and controlled with high time resolution
Skin impedance depends on temperature and can be used for skin heating monitoring where impedance drop is about 2% per C
Proprietary Information of
AMA

13. Mechanism of RF selectivity I – Geometry Effect
Electrodes
Current density is twice higher in the follicle than in surrounding tissue
Heat generation is proportional to square of current density
Proprietary Information of
AMA

14. Proprietary Information of
Heat created by RF
RF creates heat in the 30microns layer around the hair shaft
Heated layer includes hair follicle and buldge
Proprietary Information of
AMA

15. Mechanism of RF selectivity II – Impedance Decreases with Temperature
Impedance linearly decreases with Temperature Increase
RF current will flow at lower impedance part of the tissue and selectively heats it
Light acts as a trigger – preheat the target for the RF current
Proprietary Information of
AMA

16. Skin and follicle heating by RF
Heat generation
H=j2, where -conductivity, j-current density
Ratio between skin and follicle heating
Hfollicle=4 Hskin
Skin temperature increase
Tskin=ERF /(S d Cskin)
S-spot size, d-penetration depth, C-specific heat
Tskin=16 /(2x0.4x4)=5°C
Follicle temperature increase
 Tfollicle=4 Tskin=4x5=20°C
Proprietary Information of
AMA

17. Heat created by combination of Light and RF
Combination of two types of energy create uniform heating the shaft and follicle
Proprietary Information of
AMA

18. Contribution of Light and RF in Heat generation
Light provides high selectivity between hair shaft and dermis
RF energy heats mostly hair follicle and does not react to melanin of epidermis

The Aurora DS device has a definite biological effect on hair including reddish blonde and gray hair
Further studies in skin types 5 and 6, and on white hair, are on going
With an observation period of ten months it is possible to say that this is the same degree of permanent hair loss that one sees with any other laser technology
