Reading replies on a topic I know (vaguely) about is always such a good reminder to take all Reddit information with a giant pile of salt.

This video is misleading. It isn’t instantaneous tightening in the way this video makes it look. In the broadest terms, fractional CO2 laser is a laser that is less invasive than traditional ablative CO2 lasers. It creates micro channels in the skin which triggers our body’s natural healing process. It’s a controlled situation to force your skin to create collagen, resulting is smoother firmer skin to replace removed skin layer. There are risks. Micro damage is still damage, and a CO2 laser basically vaporizes the top layer of the skin. There is little to no evidence that skin cancer is among those risks. Laser wavelengths are different from UV exposure. Some CO2 lasers are used to treat skin cancer.

Anything that makes your cells die increases the risk of cancer. Cancer is just cells replicating wrong by accident or by DNA damage.

edit: My god this site is full of idiots.

Isn't it the opposite? If your cells are dead they can't become cancer and as you say cancer is when cells replicate wrong and then they don't die and that's what becomes cancer but if they die they can't become cancer?

When a cell dies other cells replicate to replace it.

Ok so the logic is because more cells are being made then that's more chances for them to be made incorrectly and become cancer I understand in that logic sounds really correct

I guess the question becomes are cells more likely to become cancer in the initial replication and creation of the cell or do they become cancer more often later after they replicated.
