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 1064nm wavelength 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

Hair Anatomy Epidermis Sebaceous Gland Bulb **Bulb/bulge are critical structures responsible for hair re-growth Follicle Bulge Vascular Supply (Matrix)

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 AnagenTelogenCatagen

How Many Treatments? Different areas have different percentages of hair in the Anagen phase. –Face, Axilla, Bikini have approximately % –Trunk and Extremities have approximately %

Time to Retreat? As a rule: –Face/Axilla/Bikini: 4-6 weeks –Trunk: 8-10 weeks –Arms & Legs: 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 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 %. 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

How does it work? 1064nm –Bulk deposition of heat can cause both collagen contraction & collagen stimulation 29

3 Techniques for Skin Tightening 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, 7-10 Hz 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
