Which of the following best describes the role of collagen remodeling in laser skin rejuvenation outcomes?
Answer: New collagen synthesis continues for 3–6 months post-treatment, improving results over time
Collagen neosynthesis and remodeling continue for 3–6 months after laser treatment, explaining why final results are not visible immediately.
Intense Pulsed Light (IPL) differs from a true laser in that IPL:
Answer: Emits a broad spectrum of non-coherent light filtered for target chromophores
IPL produces a broad polychromatic spectrum of incoherent light, unlike lasers that emit a single coherent wavelength, and uses filters to select therapeutic ranges.
For a patient with melasma seeking laser rejuvenation, which approach carries the highest risk of worsening the condition?
Answer: Aggressive ablative CO2 resurfacing
Aggressive ablative treatments can worsen melasma by triggering significant post-inflammatory hyperpigmentation and melanocyte stimulation.
Which cooling method delivers a cryogen spray immediately before each laser pulse to protect the epidermis?
Answer: Dynamic cooling device (DCD)
The Dynamic Cooling Device (DCD) sprays liquid cryogen milliseconds before each pulse, selectively cooling the epidermis while the dermis is targeted.
A patient treated with a 1,927 nm thulium fiber laser for diffuse pigmentation is most accurately described as receiving:
Answer: Superficial fractional non-ablative treatment targeting melanin and water
The 1,927 nm thulium laser is a fractional non-ablative device with shallow penetration that effectively targets superficial pigmentation and fine texture issues.
When documenting a laser resurfacing treatment, which parameter set is essential for reproducibility and safety record-keeping?
Answer: Wavelength, fluence, pulse duration, spot size, and number of passes
Complete documentation of wavelength, fluence, pulse duration, spot size, and passes allows accurate replication of successful treatments and analysis of any adverse outcomes.
The primary reason higher treatment density in fractional resurfacing increases risk is that it:
Answer: Decreases the untreated skin bridges needed for rapid re-epithelialization
Higher density means fewer untreated bridges between microscopic treatment zones, slowing re-epithelialization and raising the risk of prolonged healing and scarring.
