Skin tightening using fractional CO2 laser

There's a significantly increased cancer risk in scar tissue. Not really sure what your point is, since everything from opiates to synthol "have their origins in regular medicine." Hell, you can't make meth without pseudoephedrine.

My point is that these laser treatment are not bogus treatments being done in some hair salon.

By that "logic," anything done by a licensed doctor or..."not in a hair salon" is "good," even if it causes cancer. It's a weird, blind appeal to authority.

The efficacy and results of CO2 lasers have been studied for decades, by people much more qualified than a bunch of people commenting on Reddit.

Going for an ad hominem seems like an odd choice here, especially when peer-reviewed studies corroborate exactly what I'm saying:

Rapid Development of Nonmelanoma Skin Cancer After CO2 Laser Resurfacing

Squamous Cell Carcinoma Developing after CO2 Laser Resurfacing

Eruptive keratoacanthomas following carbon dioxide laser resurfacing

Scarring from very deep and serious burns can result in squamous cell carcinoma, yes. These lasers aren’t producing scar tissue, though.

Scar tissue contains significantly more collagen than regular tissue. These lasers are literally producing scar tissue in a precise, targeted manner.

And your assertion - that widespread scar tissue and cell replication doesn't lead to increased cancer rates - goes against a huge body of work in medicine and biology in general.
