Questions And Answers about CO2 Fractional Laser

Q: Why is there no bleeding during fractional laser treatment?

A: The focal spot of fractional laser is as thin as a hair, with a diameter of only 50-80um, which produces micropores with a diameter of 50-120um on the skin. There is a small range of thermal coagulation area around the micropores. The temperature of this area is greater than 65 degrees Celsius. This temperature can make the blood coagulate so there will be no bleeding.

Q: What is the difference between fractional laser and microneedle?

A: Microneedle is to use rolling needles to produce micropores on the skin, directly destroying the tissue structure of the skin to cause inflammatory repair reaction. The diameter of the micropores is large and there is no thermal effect, that is, thermal coagulation and thermal effect, so there will be no contraction and regeneration of collagen.

Q: Which aspects of facial wrinkles are better for fractional laser?

A: Fractional laser is more suitable for mild to moderate wrinkles, especially fine wrinkles that cannot be eliminated by surgery and soft tissue filling.

Q: Why is the penetration depth of fractional laser 2mm instead of deeper?

A: Because ultraviolet light exposure can cause elastic fiber degeneration at a depth of 2mm, the fractional laser setting controls the depth to 2mm to change the skin problems caused by photoaging.

Q: Is the effect of fractional laser obvious at the time of treatment or later?

A: The lifting effect will be very obvious at the time, mainly because the thermal effect causes collagen contraction, but there will be new collagen in the later stage. So you will find that the skin will get better and better in the later stage, the texture will become more and more delicate, and the wrinkles will become shallower.

Q: What changes will a normal person experience after a course of fractional laser treatment?

A: The facial contour will be very obviously sculpted, the face will be lifted and tightened, the skin will become smooth, delicate, shiny and elastic, fine wrinkles will disappear, and deep wrinkles will become significantly shorter and shallower. 

Q: Will the skin become sensitive and thinner after treatment?

A: Fractional laser acts on the skin in a disordered scanning manner. The focal spot diameter is only 50-80um, which has very little damage to the epidermis. After treatment, collagen fibers will be regenerated and the dermis will be thickened, so it will only improve the skin and will not thin it.
