The Principle of CO2 fractional laser
The CO2 fractional laser with a wavelength of 10600nm and finally outputs it in a lattice manner. After acting on the skin, multiple tiny thermal damage areas with three-dimensional cylindrical structures are formed. Each tiny damage area is surrounded by undamaged normal tissue, and its keratinocytes can crawl quickly, allowing it to heal quickly. It can rearrange the proliferation of collagen fibers and elastic fibers, restore the content of type I and III collagen fibers to normal proportions, change the pathological tissue structure, and gradually return to normal.
The main target tissue of CO2 fractional laser is water, and water is the main component of the skin. It can cause the dermal collagen fibers to shrink and denature when heated, and induces a wound healing reaction in the dermis. The produced collagen is deposited in an orderly manner and promotes collagen proliferation, thereby improving skin elasticity and reducing scars.
Reaction after CO2 fractional laser treatment
1. After CO2 treatment, the treated scan points will immediately turn white. This is a sign of epidermal moisture evaporation and damage.
2. After 5-10 seconds, the customer will experience tissue fluid leakage, slight edema and slight swelling of the treatment area.
3. Within 10-20 seconds, blood vessels will expand, red and swollen in the skin treatment area, and you will feel continuous burning and heat pain. The customer’s strong heat pain will last for about 2 hours, and up to about 4 hours.
4. After 3-4 hours, the skin pigment becomes significantly more active, turns reddish-brown, and feels tight.
5. The skin will scab and gradually fall off within 7 days after treatment. Some scabs may last for 10-12 days; a thin layer of scab will form with a “gauze-like feel”. During the peeling process, the skin will be itchy, which is normal. Phenomenon: Thin scabs fall off on the forehead and face, the sides of the nose are the fastest, the sides of the cheeks are close to the ears, and the mandibles are the slowest. The drier environment causes the scabs to fall off more slowly.
6. After the scab is removed, the new and intact epidermis is maintained. However, over a period of time, it is still accompanied by the proliferation and expansion of capillaries, showing an intolerable “pink” appearance; the skin is in a sensitive period and must be strictly repaired and protected from the sun within 2 months.
7. After the scabs are removed, the skin appears to be firm, plump, with fine pores, acne pits and marks become lighter, and the pigment fades evenly.
Precautions after CO2 fractional laser
1. After treatment, when the treatment area is not completely scabbed, it is best to avoid getting wet (within 24 hours). After the scabs form, you can use warm water and clean water to clean the skin. Do not rub vigorously.
2. After scabs form, they need to fall off naturally. Do not pick them with your hands to avoid leaving scars. Makeup should be avoided until the scabs have completely fallen off.
3. It is necessary to suspend the use of functional and whitening skin care products within 30 days, such as whitening products containing fruit acids, salicylic acid, alcohol, azelaic acid, retinoic acid, etc.
4. Protect yourself from the sun within 30 days, and try to use physical sun protection methods such as holding an umbrella, wearing a sun hat, and sunglasses when going out.
5. After treatment, avoid using products with functions such as scrub and exfoliation until the skin has completely returned to normal.
