CLT Tattoo Removal Procedures 3

Question 1

Picosecond lasers differ from Q-switched nanosecond lasers in tattoo removal primarily because they:

Accepted Answer

Deliver energy in shorter pulses for a greater photomechanical effect

Answer

Deliver higher total energy per pulse

Answer

Target only warm-toned (red and orange) ink colors

Answer

Use continuous-wave technology for gradual heating

Question 2

Which of the following is an ABSOLUTE contraindication for laser tattoo removal?

Accepted Answer

Active bacterial skin infection overlying the tattooed area

Answer

Fitzpatrick skin type II on the forearm

Answer

Tattoos placed more than 5 years ago

Answer

Amateur single-color tattoos

Question 3

The clinical endpoint indicating adequate treatment during a tattoo removal session is:

Accepted Answer

Immediate whitening (frosting) of the treated area

Answer

Complete visual disappearance of the tattoo during treatment

Answer

Mild erythema only, with no tissue response

Answer

Visible blistering of the skin surface

Question 4

Which aftercare instruction is MOST important immediately following laser tattoo removal?

Accepted Answer

Apply antibiotic ointment and keep the area clean and moist

Answer

Expose the area to sunlight to stimulate vitamin D synthesis

Answer

Scrub the treated area gently to remove loosened dead skin

Answer

Apply bare ice packs directly to the skin for 24 hours continuously

Question 5

In the context of laser tattoo removal, 'selective photothermolysis' means:

Accepted Answer

The laser selectively destroys tattoo ink while minimizing damage to surrounding tissue

Answer

The laser heats the entire dermis uniformly to dissolve ink

Answer

Only lighter skin tones are selectively safe for treatment

Answer

Thermal energy coagulates ink particles into larger clumps for removal

Question 6

When treating darker Fitzpatrick skin types (IV–VI) for tattoo removal, which parameter adjustment is recommended?

Accepted Answer

Use lower fluences and extend intervals between sessions

Answer

Increase fluence to fragment ink more aggressively

Answer

Use longer pulse durations to reduce peak power and heat buildup

Answer

Switch to a CO2 ablative laser to bypass melanin absorption

Question 7

Which ink colors are generally LEAST responsive to treatment with the Q-switched Nd:YAG 1064nm laser?

Accepted Answer

Yellow, green, and light blue

Answer
