CURRENT TREATMENTS

Unwanted Tattoo & Benign pigmented Lesions

What were the laser treatment choices so far?

For the past 20 years, Q-switched lasers with nanosecond pulse duration have been available:

• Q-switched Nd:YAG (1064 nm & 532 nm) • Q-switched Alexandrite (755 nm) • Q-switched Ruby (694 nm)

WHAT LIMIT EFFICACY OF CURRENT TXTS?

Epidermal Pigmented Lesions

• Color density - sometimes too light • Precise setting - limited fluence settings • Side effects - high risk for PIH

Dermal Pigmented Lesions

• Depth of penetration - deep • Lack of power - less clearance • Thermal damage - nanosecond, truly selective? • Sessions - requires many sessions • Pain - painful even with anesthetic creams • Side effects - recalcitrant, recurrence, hyper- and hypo-,

mottled hyperpigmentation

WHAT LIMIT EFFICACY OF CURRENT TXTS?

Tattoo Removal

• Colors - not black always

• Particle size - small to large conglomerations

• Ink composition - various, unknown, unidentified

• Location / Depth - various, shallow, deep

• Efficacy - not always 100 %

• Sessions - requires many sessions

• Side effects - scarring, PIH

TRT (THERMAL RELAXATION TIME)

Time that takes for an object to cool down to half of its increased temperature gap from its initial temperature.

It is a rule that a smaller object cools faster than a larger object of the same material and shape which means that the smaller target has a shorter thermal relaxation time.

SELECTIVE PHOTOTHERMOLYSIS

“Selective absorption of light pulses by pigmented target (specific chromopore) such as blood vessels, pigmented cells, and tattoo ink particles to achieve selective thermally mediated injury” RR Anderson et al, Science 220:524, 1983

SELECTIVE PHOTOTHERMOLYSIS

Wavelength that is absorbed by the target. Pulse Width that is less than or equal to cooling: Thermal Relaxation Time (TRT). Energy that will enable to target to reach the damaging temperature.

FEEDBACKS OF PS LASER USERS

Nanosecond laser Picosecond laser

5-10 ns : Q-Switch Nd:YAG 50-100 ns : Q-Switch Alexandrite 20-50 ns : Q-switch Ruby

750 ps : picosecond Alexandrite 350-750 ps : picosecond Nd:YAG

Photoacoustic effect : significant Photoacoustic effect : more significant

More thermal effect - heats transferred to pigment and surrounding tissues

Less thermal effect - less painful - less post treatment erythema

Weaker mechanical fragmentation - but, not insufficient to conventional use - needs more energy than pico laser

Stronger mechanical fragmentation - can treat with lower energy

Governed by thermal relaxation time Mainly governed by stress relaxation time (mechanical stress)

FEEDBACKS OF PS LASER USERS

• Limitations on current 532 nm picosecond

• Fluence parameters are not reduced as 1:1 proportional to the decrease of pulse duration. (e.g. Fluence setting is usually 1/2 or 1/3 of the fluence setting in nano device.)

• Still require multiple wavelengths

HIGHLIGHTS OF PICOPLUS (1)

• Four high-powered wavelengths

• Still with sufficient and stable high and low energy output

• Widely-ranged fluence

• Precisely controllable fluence (jog & shuttle)

• 5 Handpieces (including Focus Dots Handpiece) • Dual pulse duration: pico and nano

• Built-in storage

Page 110: PICOPLUS - drshumailakhan.com€¦ · TRT (THERMAL RELAXATION TIME) Time that takes for an object to cool down to half of its increased temperature gap from its initial temperature.

HIGHLIGHTS OF PICOPLUS (2)

• Clear resistant tattoos and recalcitrant pigmented lesions (e.g. Café-au-Lait, Nevus of Ota, ABNOM, Nevus Spilus, Blue Nevus, etc.)

• Reduces number of sessions for tattoos and pigmented lesions.

• Always better results than nano.

• Protects epidermis even at higher fluence parameters

• 532 nm at picosecond is good choice for epidermal pigmented lesions.

• Provides prices control especially at 532 nm

• Both hypo- and hyper- pigmentation at nano. Only hyper-pigmentation at pico.

• Less post-treatment pain sensation and thermal accumulation

• 1064 Focused Dots HP for final resurfacing is good!
