CO2 lasers are typically used to perform more thorough skin resurfacing procedures, such as the removal of moderate to deep facial lines and wrinkles. Due to the extensiveness of CO2 laser treatment, the recovery time takes 2 weeks and the damage to surrounding skin tissue is more pronounced than erbium laser surgery. Erbium laser surgery is more suitable for patients with mild skin problems that can be treated with gentler laser power. The recovery time for erbium laser surgery is only about 1 week.
