Carbon dioxide lasers are used for different purposes and are charged in two ways: for the treatment of filiform warts, pigmented moles, and dermatophytes, the number of lasers is calculated according to the number of lasers, which ranges from $15 to $50 a piece, and for fractional lasers used for the treatment of post-acne depressed scars, the charge is calculated according to the area, which is about $300 to $600/cm². Carbon dioxide lasers used to treat filiform warts, pigmented nevi, and dermatomas have little tissue damage and quick recovery, but may form discoloration. The price of carbon dioxide two-fractional laser is about 300 yuan to 600 yuan/cm², mostly used to treat enlarged pores, post-acne depressed scars, etc. The price of carbon dioxide fractional laser is affected by the severity of the condition, the area of use and so on. If the facial pigmentation, acne pits are heavier and the area is larger, all of them will make the cost higher. Meanwhile, the charges of different regions and hospitals are different. Carbon dioxide laser is a kind of gas laser, its wavelength is 10.6μm, after acting on the skin, it can make the local skin be vaporized, so as to achieve the purpose of improving the skin. Carbon dioxide laser has the effect of stimulating the skin’s self-repair function, and it can make a lot of tiny holes on the surface of the skin, form thermal damage in the skin layer, cause a series of self-repair of the skin, and it has the effect of removing lesions, repairing medium and heavy light damage, and also has a very good effect on repairing scars.
