Question 1

The Fitzpatrick skin type classification is most important in laser treatment planning because it predicts risk of?

Accepted Answer

Post-inflammatory hyperpigmentation

Answer

Higher Fitzpatrick skin types (IV–VI) have greater melanin content, placing them at significantly increased risk of post-inflammatory hyperpigmentation after laser procedures.

Question 2

Fractional laser resurfacing is distinguished from fully ablative resurfacing primarily because it?

Accepted Answer

Treats only a fraction of the total skin surface per session

Answer

Fractional technology creates microscopic treatment zones surrounded by untreated tissue, allowing faster healing and lower risk compared to fully ablative treatments.

Question 3

The principle of selective photothermolysis requires that laser pulse duration be shorter than?

Accepted Answer

The thermal relaxation time of the target chromophore

Answer

Selective photothermolysis dictates that pulse duration must not exceed the thermal relaxation time of the target so heat is confined to the chromophore and spares surrounding tissue.

Question 4

Ultherapy (microfocused ultrasound with visualization) achieves its tissue-tightening effect by targeting energy at which anatomical layer?

Accepted Answer

Superficial muscular aponeurotic system (SMAS) at 4.5 mm

Answer

Ultherapy delivers focused ultrasound to the SMAS layer at 4.5 mm depth, mimicking a surgical plane to stimulate collagen remodeling and tissue lifting.

Question 5

Cryolipolysis (CoolSculpting) reduces subcutaneous fat by inducing?

Accepted Answer

Controlled apoptosis of fat cells through sustained cooling

Answer

Cryolipolysis exploits the selective sensitivity of adipocytes to cold, triggering apoptosis at temperatures that leave overlying skin unharmed.
