Key Parameters for Successful LHR1. Wavelength
Nd:YAG• 1064 nm• Skin Types I-VI• Safest wavelength for
darker skin and tanned patients
• Effective on dark, coarse hair
Pulsed Light (IPLs)• 590 to 1200 nm• Skin Types I-V; best for light
skin and dark hair• Shallower penetration –
deeper, thicker hairs not treated as effectively
• Less precise – can lead to heating of skin pigment
Alexandrite• 755 nm• Skin Types I-V; ‘gold standard’
for I-IV• More effective for finer, lighter
hair• Most globally requested,
trusted and utilized wavelength
Diode Laser• 800, 810 nm• Skin Types I-III; less for IV, V• Peak Power/Brightness is a
fraction of Nd:YAG/Alex lasers – can be less effective on finer, lighter hair
• Blind to treatment area

Key Parameters for Successful LHR2. Spot Size • Treat target and reduce risk to deeper structures by selecting
appropriate spot size (particularly for 1064 nm)
• Smaller spot size = less penetration, more scatter – Targets more superficial structures (superficial, fine hair follicles)
• Larger spot size = deeper penetration, less scatter– Targets deeper structures (hair)
Key Parameters for Successful LHR3. Pulse Duration (PD)• Measured in milliseconds (ms), based on target size and skin type• Pulse duration controls efficacy
– Speed of heat escape is proportional to target size– Shorter pulses are effective because energy is delivered faster than it
can escape– Longer pulses protect the epidermis because heat can escape
preventing heat rise (Nd:YAG)• Pulse must be shorter than the thermal relaxation time of the hair
– Coarse hair = 25-45 ms– Fine hair = 3-10 ms
Key Parameters for Successful LHR4. Fluence• Measured in Joules/cm2 (J/cm2), amount of energy applied in a
given area • Total energy delivered is determined by both fluence and spot size• Adjustments should be made based on clinical endpoints and
epidermal response
DecreaseLarge Spot Sizes
Darker Skin Types
IncreaseSmall Spot Sizes
Lighter Skin Types
Fluence
Key Parameters for Successful LHR5. Cooling• Laser targets melanin in target hair follicles – cooling
protects the epidermis• Cooling reduces the temperature rise in the epidermis and
protects it from damage, permitting higher fluences to be delivered
• Cooling acts as a local anesthetic for improved comfort• Types of cooling
– Contact Cooling– Cryogen (refrigerant) Cooling– Refrigerated Air Cooling
• Contact cooling is superior as Cryogen cooling does not provide the same level of variable protection and safety

Sapphire Contact CoolingThe Importance of Cooling
• Melanin is the target in hair follicles, but is also a target in the epidermis – Cooling reduces the temperature rise in the epidermis and
protects it from damage, permitting higher fluences to be delivered to the hair follicles
• Cooling acts as a local anesthetic for improved comfort
• Cryogen (refrigerant) cooling does not provide this level of variable protection and safety
Sapphire Contact CoolingThe Physicians Choice for Comfort & Safety
• “Sapphire contact cooling is superior for laser hair removal – index matching and compression enable target structures to be heated more efficiently while pre-, parallel-, and post-cooling spares the epidermis.”
Source: Lasers Surg Med 2000; 26(2): 130-144Evaluation of Cooling Methods for Laser DermatologyH.H. Zenzie, MS, G.B. Altshuler, PhD,M.Z. Smirnov, PhD, and R.R. Anderson, MD
• With a sapphire window temperature variable from 4oC to 20oC, physician have controllable cooling to maximize safety, comfort and results
Sapphire Contact Cooling Improved Efficacy with Refractive Index Matching
• When the refractive index is “matched”, there is little or no bending (refraction) when the light enters the transmission medium
• Refractive index values of sapphire and epidermal tissue are optimally matched – as a result, the coupling of laser energy into tissue is more efficient than through air
Sapphire refractive index is optimally matched to skin and results in more efficient coupling of laser energy to
follicular target structures
Refractive index mismatch between air and skin results in less efficient coupling of laser
energy to target structures
excel HR Other Technology
Sapphire Contact CoolingIndex Matching & Optical Damping with Sapphire Lens
• Minimizing the light bending (refraction) ensures that more of the light reaches the target tissue
• Matching the light path with the refractive index allows the light to back scatter and escape without causing heat build up at the skin’s surface – this is referred to as optical damping
• Sapphire contact cooling creates near ideal conditions for optical damping – a thin liquid layer can be used to provide optical coupling and enhance the optical damping effect
Index matching between sapphire and skin allows back scattered light to
escape, further protecting the epidermis from heat
build-up
Refractive index mismatch causes
internally reflected laser light to accumulate under the skin and contribute to
epidermal heating

Sapphire, n = 1.7
Air , n = 1.0

Gel, n = 1.4
Skin, n = 1.4
Sapphire, gel and skin refractive indexes are closely matched and

WINDOW
excel HREnhanced Efficacy With Compression
• Skin compression collapses blood vessels, stretches the skin and often decreases its thickness – thus shortening the distance to follicular target structures for more efficient heating
Sapphire Contact Cooling Patient Safety Benefits
• Contact cooling guarantees that laser treated areas are cooled and protected– Effective as long as the sapphire is in contact with the skin.
• Cryogen-spray cooling can result in burns if laser and cryogen are misaligned– Only cools until the cryogen evaporates– Incorrect positioning can result in burns, hyperpigmentation
“Now it’s over 2 months after and I have scars everywhere where I was treated!”
LASER TREATED AREA
LASER TREATED BUT NOT COOLED AREA
CRYOGEN SPRAY AREA
Sapphire Contact Cooling Other Operational Benefits
• Environmental– No contribution to global warming like cryogen spray
• Tetrafluoroethane (R-134a) has a high global warming potential• Candela DCD inventors @ Beckman Institute urging alternative1,2
• Operating Environment– Doesn’t expose operator and patient to harmful CFCs3 like cryogen
spray
• Operating Efficiency– Doesn’t require 15 minute “warming time” like cryogen– No pre-treatment alignment of “spray pattern” required
• System operating costs– No impact to operating costs – disposable cryogen canisters impact
operating costs significantly ($5-45K/year)1. Jia W, Svaasand LO, Nguyen TB, Nelson JS Dynamic skin cooling with an environmentally compatible alternative cryogen during laser surgery.

for skin cancer
excel HRPrecautions
• Do not treat patients who have taken Accutane in the past 6 months
• Anticoagulants may increase the risk of purpura or bruising
• Gold therapy may cause blue-gray discoloration• Vitiligo may cause de-pigmentation• Pre-treatment with an antiviral may be indicated for
patients with herpes• Use caution when treating patients with a history of
keloids or hypertrophic scarring• Patients with hormone disorders (e.g., Polycystic
Ovarian Syndrome) may not see effective hair reduction• Do not treat over open wounds
excel HRWarnings
• Do not treat over dysplastic nevi or questionable pigmented lesions
• Do not treat over or close to: – Tattoos or permanent make-up–Metal or electronic implants
excel HRPatient Selection
• Patients should have brown or black hair– Laser light is not absorbed by white, gray, red or light-
blond hair• excel HR is indicated for use on all skin types
– The 755 nm wavelength is recommended to treat skin types I-V
– The 1064 nm wavelength is recommended to treat skin types I-VI including tanned skin
excel HRPre-Treatment Guidelines
• Clean the skin by removing all make-up and/or topical anesthetic
• Ensure that the treatment area is clean shaven• Instruct patients to not wax, pluck or tweeze hair
between treatments• Topical anesthetic is optional and must be
removed before treatment– CAUTION: Toxicity may result from overuse.
Consult the product labeling for any anesthetic used
• Ensure that ALL people in the treatment room are wearing safety eyewear
excel HRTreatment Precautions
• Be extra cautious when treating delicate or highly sensitive areas (knuckles, genitalia, ears, upper lip, etc.)– Provide extra cooling with handpiece and/or frozen gel pack.
Thinner skin is more easily damaged– Insert damp cotton ball inside ear canal when treating the ear– Pull skin away from testes to treat– When treating near the mouth, a moist gauze can be placed
between the lips and teeth to protect teeth from discomfort• Use extreme caution when treating near the eye
– Always treat outside the orbital rim of the eye aiming the beam away from the orbit.
– Always use patient eye protection– Point the treatment window away from the eye and apply to
the skin outside of the orbital rim
excel HRPatient Comfort
• Cool Compress – May be applied to increase patient comfort and increase
epidermal protection• Topical anesthetic can be applied
– For highly sensitive areas– For patients with low pain tolerance– Must be removed before treating– CAUTION: Toxicity may result with overuse– Consult the manufacturer’s labeling
excel HRPost Treatment Guidelines
For best results, ensure patient adheres to post-care instructions: – Avoid sun exposure and use a broad spectrum (UVA/UVB)
sunscreen – Redness and peri-follicular edema (looks like a rash/bug bites)
are common and resolve with time– Bruising and swelling are less common but may occur and will
resolve with time – If a blister develops, treat as a wound– Hair may take up to 2 weeks to fall out – Avoid heat – hot tubs, saunas, etc. for 1-2 days – Avoid skin irritants (examples below) for a few days post-
treatmentProducts containing tretinoin, retinol, benzoyl peroxide,
glycolic/salicylic acids, astringents, etc. – Do not wax or pluck between treatments
excel HRTreatment Intervals
• Treatment Interval recommendations are a general guideline only and are a compilation of intervals used by successful operators• Facial hair: 6-8 week intervals between
treatments• Body hair: 8-10 week intervals between
treatments • Back or Leg hair: 10-12 week intervals
between treatments • To maximize hair response, it is often best to
space the treatments further apart

My Laser Journey Cutera Excel HR
2014 - Cutera Excel HR was introduced– I did not need another laser. – However, due its good technical parameters and
low consumable costs, I saw its advantage and bought it.
How could I use both Cynosure and Excel HR? Could Cynosure patients adopt to Excel HR?
• Could we convince Cynosure patients to continue their sessions with Excel HR? – To take advantage of the low consumable cost
• I requested them to try Excel HR• If they were not pleased with the results and
comfort, they would go back to Cynosure. • Patients were more pleased with Excel HR. • Once again, I had made a good choice.
Summary
My great experiences with Excel HR:– Alexandrite– NdYag
My great experiences with excel HRAlexandrite
• With the continuous (pre, parallel, post) cooling ;– There is less pain, less risk of side effects hence
safer and certainly effective laser hair removal.• No breaks needed during treatment because
of less pain– Treatment takes a shorter time.
My great experiences with excel HRAlexandrite
With quick start time, real time calibration and quick switching time, there is no wasting of time.
My great experiences with excel HRAlexandrite
The matching of the laser path and refractive index of the skin, gel and contact window reduce scattering of laser light. – Thus, the light only reaches the targeted location.

My great experiences with excel HRND Yag
Due to truPulse technology, – Stable energy can be supplied throughout the pulse
duration, in the remaining spot area.
My great experiences with excel HRND Yag
Flexibility in pulse duration. – Ability to set up the pulse duration in milliseconds
(e.g. 0.3ms) to warm up the area under the skin during rejuvenation
– For thick hairs or veins, you can set up the required energy with high pulse duration (e.g. 40 ms)
My great experiences with excel HRND Yag
With contact cooling and parallel cooling;• Vascular treatments and laser hair removal procedures are
less painful.• Before, only pre and post cooling was available.
With large spot size up to 18mm;• Laser hair removal can be done faster
