Laser Hair Removal
Laser Hair Removal
• How does it work?– Targets the pigment in the hair follicle.– Heat is absorbed and destroys the cells
lining the hair follicle specifically around the bulb, bulge, and vascular supply.
Permanent Hair Reduction
The FDA allows us this definition:
“long-term stable reduction in the number of hairs re-growing after a treatment regime”
How Effective is it?• Studies have shown up to 80% reduction in
hair after a series of treatments• The 755nm & 1064nm wavelengths will NOT
treat white, blonde, or gray hairs! • Some reds hairs will not achieve desired
efficacy. • Patients should be informed of all possible
outcomes prior to treatment

Bulb
**Bulb/bulge are critical structures responsible for hair re-growth

Cycles of Hair Growth
• What are the 3 cycles of hair growth?– Anagen: Hair is actively growing– Catagen: Hair is dormant– Telagen: Hair is falling out
Hair Biology
Anagen TelogenCatagen
How Many Treatments?
• Different areas have different percentages of hair in the Anagen phase.– Face, Axilla, Bikini have approximately 20-
35%– Trunk and Extremities have approximately 10-
20%
Time to Retreat?
• As a rule:– Face/Axilla/Bikini: 4-6 weeks– Trunk: 8-10 weeks– Arms & Legs: 10-12 weeks
• Or within 7 days of when regrowth is observed.

Bottom Line• For best results, multiple treatments will be
needed. – For most areas 4-6 treatments are necessary to
achieve desired hair clearance. – One may need more or less than 6 treatments
depending on hair type, previous methods of hair removal, and skin color.
• Results may vary from patient to patient and to various degrees of efficacy.
Pre-Treatment Instruction• Before
– Shave hair 24-48 hours prior to treatment– If the patient has a history of cold sores/fever blisters, an
anti-viral can be prescribed – If there is concern over pigmentary changes, a
prophylactic bleaching cream can be used weeks prior to treatment
Pre-Treatment Instruction
– NO Plucking – 6 weeks prior or after– NO Waxing – 6 weeks prior or after– NO Tweezing – 6 weeks prior or after
Patients should only shave
Clinical Endpoints• PFEs
– Perifollicular erythema: The treatment area should appear red
– Perifollicular edema: There should be swelling around each hair follicle
• Some patients will experience a hive like response• Lighter hairs may not respond as significantly
Post-Treatment Instruction• After
– Cool compresses can be used to reduce patient discomfort & swelling
– Aloe vera– Topical Cortisone cream– Sun block of 30+ SPF
Treatment Technique• 3 Things to ALWAYS remember while treating:
– FLUSH: The distance gauge should be flat and in contact with the skin’s surface
– PERPENDICULAR: The hand piece should be 90° to the skin’s surface
– OVERLAP: Pulses should be overlapped at 20-30%. Think of the Olympic Rings
Complications• There are risks and
complications that can occur from laser treatment.
• Use of conservative DCD settings are important.
• Complications are rare!
• Heat rash• Bruising• Scarring• Infection• Hyper-pigmentation• Hypo-pigmentation• Swelling• Welting

Pigmented Lesions – 755nm only
Pigmented Lesions
• A pigmented lesion is caused by an abnormal production of melanin which makes it visible on the skins surface
Pigmented Lesions• The following benign pigmented lesions can be
treated with the 755nm wavelength:– Mottled or hyperpigmentation– Lentigines– Ephelides (freckles)– Epidermal melasma– Café’ au lait
Pigmented Lesions• Lentigines:
– Are small, tan to medium brown lesions that are located on the skins surface
– Usually caused by excessive sun exposure– Need to be differentiated from the potential skin
cancers. (i.e., have it checked off by a physician)
Lentigines
Pigmented Lesions• Ephelides:
– Also known as freckles– Commonly seen on fairer skinned patients
Ephelides
Pigmented Lesions
• Café’ au lait:– Are typically light tan to pale brown patches that
are seen at birth or soon after.
Café’ Au Lait
Pigmented Lesions• Remember that this will treat Epidermal
pigmentation issues.– NOT LIKELY TO RESPOND
• Nevi of Oto or Ito• Melanocytic Nevi
– Should only be treated by dermatologist• Blue Nevi
Pigmented Lesions
• Method of Treatment:– Treat only on Skin Types I-III (and Asian skin)– No DCD is used.– May require multiple treatments (2 – 3 TX)– For treatment of smaller lesions a small spot
size should be used.
Pigmented Lesions• Some factors that could possibly trigger a re-
ecurrence of pigmented lesions are:– Hormonal inbalance– Pregnancy– Medications– Menopause– Sun Exposure
Pigmented Lesions• Potential Side Effects:
– Discomfort– Bruising– Swelling– Scabs– Hyper-pigmentation– Hypo-pigmentation
– Infection– Scarring– Lesion Recurrence
Side effects are quite rare!
Pigmented Lesions
• Clinical Endpoint– You may hear a “Snap” while treating. – The darker the lesion, the louder the “Snap”– It is not uncommon to see a “Frosting” of the lesion
Single Pulse Only!
Pigmented Lesions• Clinical Endpoint:
– The lesion will darken within 5 - 10 minutes after treatment and may remain so until the lesions forms a micro-crust. Use of an ointment is recommended. Aquaphor, bacitracin or even vaseline can be used to keep area moist until the crust falls off. The skin underneath will be pink. There is a gradual return to normal skin color over time.
Pigmented Lesions• Avoidance of direct and indirect sun exposure for at
least 2 weeks before & after the laser treatment is advisable.
• Sunblock of at least SPF 30 on the treated area daily. Sun exposure may contribute to hyperpigmentation in treated area.

Vascular Lesions & Linear Telangiectasia755nm & 1064nm Wavelengths
Which Does What?
1064nm– Facial Vessels– Leg Veins
40
755nm– Facial Vessels– Leg Veins– Hemangiomas– Resistant PWS
Leg Telangectasia or Spider Veins• Sclerotherapy is the
GOLD STANDARD for the treatment of leg veins
• The 755nm & 1064nm wavelengths can clean up what Sclerotherapy does not
• Veins < 3mm in size are treatable
Special Considerations
• Vitamin E, Aspirin, Ibuprofen, Fish Oils or other Blood thinners may increase the likelihood of bruising. Avoid for several days if possible, if not, practitioners should perform test spots
• When treating lower extremities diabetic patients should have clearance from their primary physicians
• Darker Skin Types should only be treated with the 1064nm wavelength
Pre-Treatment• Squeaky clean skin!• No tanned skin!• No Topical anesthetics• Topical Alpha-hydroxy
– Can be used for 1-2 weeks prior to treatment• Measure vessel size
Clinical Endpoints – 755nm• Facial Vessels & Leg Veins
– Structure will vaso-spasm or darken – Peri-vascular erythema is normal
• Hemangiomas– Transient purpura
• Resistant PWS– Transient gray color that evolves into deep purpura
44
Clinical Endpoints – 1064nm• Facial Vessels
– ONLY the 1.5mm spot size should be used on the face
– Vessels should disappear and erythema the end result• Leg Veins
– Vessels should disappear– Wheal & Flare or Cat Scratch appearance after about
5minutes
45
Post treatment• Apply pressure to treated area after a few
pulses• Cool Compresses• Topical Cortisone Cream• Encourage sun block 30+ SPF• Avoid activities that cause vasodilatation or
increase blood pressure for 3-5 days

Wrinkle Reduction & Skin Tightening
What’s The Difference?
755nm– Thermal Injury
stimulates the body’s response to create collagen
1064nm– Bulk deposition of
heat can cause both collagen contraction & collagen stimulation
48
Use of 755nm• Treatment of skin types I-IV• Requires a series of treatments performed
once a month• Technique is similar to LHR• Clinical endpoints are slight edema &
erythema
49
Use of 1064nm• Treatments can be performed on all skin
types• Requires a series of treatments performed
once a month• Several techniques to choose from• Clinical endpoint is achieving a surface skin
temperature of 40-43º C
50
1064nm for Skin Tightening• Three different techniques
– *New Taylor• 18mm, 50ms, 18 J/cm² with the DCD turned off – 3 Passes
– Keys• 10mm, 50ms, 20 J/cm², DCD off, Double Pulse/3 Passes
– Painting• 8-10mm, .25-.5ms, 12 J/cm², DCD off, 5-7Hz
• All deliver bulk heating into the dermal layer of skin
Clinical Endpoint?• The use of an Infra-Red
Thermometer allows us to achieve a surface temp of 40°-44° C
• This translates to an approximate dermal temp of 65° C
• This is the temperature that can cause collagen contracture
