Laser skin resurfacing goes by several names, which matters when you compare quotes from different practices. www.plasticsurgery.org says laser skin resurfacing, also known as a laser peel, laser vaporization and lasabrasion, can reduce facial wrinkles, scars and blemishes. For readers in Saline, Michigan, the same word on two quotes may not mean the same treatment.
Proposals you may be comparing
dermnetnz.org says the main laser resurfacing techniques used today are non-ablative laser systems, fractional resurfacing systems, and combined systems. A quote that names a laser without saying which of these it belongs to is missing a detail worth asking about.
Three published references are worth reading alongside any quote. my.clevelandclinic.org keeps a page on laser skin resurfacing, lasers types, skin conditions and what to expect. There is also a review of current laser resurfacing technologies, and a comparison of CO2 and Er:YAG laser therapy for acne scars.
The articles, read as a checklist
Each article takes one question a second opinion should answer: how the types differ, and what recovery asks of you.
The assumption most worth questioning
One assumption is worth testing first: that the downtime in a quote comes from a published source rather than from the practice's habit. Ask which source its healing estimate rests on, and whether that source describes the same type of laser.
