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.

5
Permanent Hair Reduction
The FDA allows us this definition long-term
stable reduction in the number of hairs
re-growing after a treatment regime
6
How Effective is it?

• Studies have shown up to 80 reduction in hair
  after a series of treatments
• The GentleLASE 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

Anagen
Telogen
Catagen
10
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

11
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.

14
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

15
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

16
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

17
Post-Treatment Instruction

• After
• Cool compresses can be used to reduce patient
  discomfort swelling
• Aloe vera
• Topical Cortisone cream
• Sun block of 30 SPF

18
Treatment Technique

• 3 Things to ALWAYS remember while treating
• FLUSH The distance gauge should be flat and in
  contact with the skins surface
• PERPENDICULAR The hand piece should be 90 to
  the skins surface
• OVERLAP Pulses should be overlapped at 20-30.
  Think of the Olympic Rings

19
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

20
Pigmented Lesions
21
Pigmented Lesions

• A pigmented lesion is caused by an abnormal
  production of melanin which makes it visible on
  the skins surface

22
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

23
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)

24
Lentigines
25
Pigmented Lesions

• Ephelides
• Also known as freckles
• Commonly seen on fairer skinned patients

26
Ephelides
27
Pigmented Lesions

• Café au lait
• Are typically light tan to pale brown patches
  that are seen at birth or soon after.

28
Café Au Lait
29
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

30
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.

31
Pigmented Lesions

• Some factors that could possibly trigger a
  recurrence of pigmented lesions are
• Hormonal imbalance
• Pregnancy
• Medications
• Menopause
• Sun Exposure

32
Pigmented Lesions

• Infection
• Scarring
• Lesion Recurrence
• Side effects are quite rare!

• Potential Side Effects
• Discomfort
• Bruising
• Swelling
• Scabs
• Hyper-pigmentation
• Hypo-pigmentation

33
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!

34
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.

35
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.

36
Vascular Lesions Linear Telangiectasia

• 755nm Wavelength

37
GentleLASE Does What?

• Vascular Lesions
• Facial Vessels
• Leg Veins
• Hemangiomas
• Resistant PWS

37
38
Leg Telangectasia or Spider Veins

• Sclerotherapy is the GOLD STANDARD for the
  treatment of leg veins
• The 755nm wavelength can clean up what
  Sclerotherapy does not
• Veins lt 2mm in size are treatable

39
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 not be treated with the
  755nm wavelength

40
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

41
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

41
42
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

43
Wrinkle Reduction
44
How does it work?

• 755nm
• Thermal Injury stimulates the bodys response to
  create collagen

44
45
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
