  1. Aurora DSR ELOSTM Technology and key features AMA Proprietary Information of AMA

  2. ELOSTM Technology for Aesthetic medicine • Utilize optical energy and electrical (radio frequency) simultaneously • Two different selectivity mechanism for optimal treatment • Epidermal cooling • Active dermal monitoring TM Proprietary Information of AMA

  3. Aurora applications • Aurora DS indicated for non invasive hair removal • Light hair • Dark skin types • Aurora SR indicated for Skin Renewal • Pigmented lesion • Vascular lesion • Skin texture improvement Proprietary Information of AMA

  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. 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 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 _ Light-based Hair removal + Proprietary Information of AMA

  6. What is the main Light problem? Energy Light Skin Dark Hair Dark Skin Dark Hair Light Skin Light Hair Dark Skin Light Hair Dermis damage Epidermis damage Hair damage Proprietary Information of AMA

  7. Treatment window for light based systems Proprietary Information of AMA

  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

  10. Technology Cooling Light RF Proprietary Information of AMA

  11. Temperature distribution created by light • Light heats selectively hair shaft • Bulge and follicle are damaged due to heat transfer from hair shaft Shaft Follicle Proprietary Information of AMA

  12. 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. 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 RF • Light provides high selectivity between hair shaft and dermis • RF energy heats mostly hair follicle and does not react to melanin of epidermis Proprietary Information of AMA

  19. RF Current Distribution Cold epidermis Dermis Pre-heated vessel Proprietary Information of AMA

  20. Aurora pulse sequence Light RF energy RF energy Testing pre-pulse to ensure coupling and skin calibration for RF monitoring Intense pulse Fine heat adjustment Proprietary Information of AMA

  21. Light ~25ms Short and Long Pulses Short RF energy Long 50ms 50ms Proprietary Information of AMA

  22. ISL safety feature Impedance Temperature Light Energy RF energy Testing pre-pulse Intense pulse Fine heat adjustment Proprietary Information of AMA

  23. Impedance safety limit (ISL) 0 10 20 30 40 ISL= 10%, energy is cut off Light Light ISL= 30%, all energy is delivered Light Light RF energy Proprietary Information of AMA

  24. Clinical results with the Aurora DSR Proprietary Information of AMA

  25. Treatment technique • Incomplete contact cooling • All RF current is concentrated in one point, potential for increased tissue temperature at contact points. • Complete contact cooling • RF current is distributed over entire electrode surface Proprietary Information of AMA
