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 Follicle Epidermis Sebaceous Gland Bulge Vascular Supply (Matrix) 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 Catagen Telogen How Many Treatments? • Different areas have different percentages of hair in the Anagen phase. – Face, Axilla, Bikini have approximately 2035% – Trunk and Extremities have approximately 1020% 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. Hair Growth Information Telogen Duration Follicles Density / cm² Depth of follicle Body Area % Anagen Hair % Telogen Hair Axillae 30% 70% 3 months 65 3.5-4.5 mm Brow and Ears 10-15% 85-90% 3 months 50 2-2.5 mm Beard 70% 30% 10 weeks 500 2-4 mm Upper Lip 65% 35% 6 weeks 500 1-2.5 mm Scalp 80-90% 13% 3-4 months 350 3-5 mm Trunk 10-20% 80-90% 4 months 70 2-4.5 mm Pubic Area 20-30% 70% 3 months 70 3.5-4.5 mm Arms 20% 80% 18 weeks 80 2-4.5 mm Legs & Thighs 20% 80% 6 months 60 2.5-4 mm Breast 30% 70% 3 months 65 3-4.5 mm 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 2030%. 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 Click to edit Master title style Vascular & Linear Telangiectasia • Click to Lesions edit Master text styles – Second level 1064nm Wavelength • Third level – Fourth level » Fifth level GentleYAG does what? 1064nm – Facial Vessels – Leg Veins 22 Leg Telangectasia or Spider Veins • Sclerotherapy is the GOLD STANDARD for the treatment of leg veins • The 1064nm wavelength 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 – 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 26 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 Click to edit Master title style • Click to edit Master text styles – SecondReduction level Wrinkle & Skin Tightening • Third level – Fourth level » Fifth level 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 Click to edit Master title style • Click to edit Master text styles – Second level Thank You • Third level – Fourth level » Fifth level
