CO2 fractional laser is widely used in the field of skin beauty. From whitening and removing spots to anti-aging, it has achieved quite good therapeutic effects, because CO2 fractional laser is the first choice for beauty lovers to fight skin problems and anti-aging beauty.
What is a CO2 fractional laser？
The CO2 array technology is derived from the lattice photothermal decomposition theory of Harvard University’s photomedicine experts. It is a minimally invasive laser treatment technique. The CO2 array laser not only reduces the side effects of the ablation laser, but also retains its therapeutic effect.
These light beams can instantly vaporize the tissues and send out a strong signal for the synthesis of collagen, which enables the skin to initiate the function of tissue repair and collagen rearrangement, thereby restoring the normal appearance and elasticity of the skin.
Principles of Treatment：
CO2 fractional laser can emit lasers that are as thin as a hair and arranged in a matrix. It uses high-energy lasers to make small and orderly tapered holes in the skin, effectively stimulating the proliferation and sufficiency of collagen. The contraction and repair of the tapered holes make the skin firm, delicate and elastic, and achieve the effect of skin rejuvenation.
CO2 fractional laser treatment will only cover part of the skin tissue, and the newly punched holes will not overlap each other, so part of the normal skin is preserved, which can speed up recovery.
What is the difference between a CO2 fractional laser and a traditional laser？
Using the dot matrix principle, small holes are evenly punched in the skin, causing a series of skin biochemical reactions to achieve the effects of wrinkle, firmness and scar removal. The energy peak of the CO2 fractional laser is larger than that of the traditional laser, and there is normal skin between the points, which is good for repairing. Therefore, the fractional laser has a stronger stimulating effect on collagen and has fewer side effects. For yellow people, traditional exfoliating lasers tend to leave pigmentation, but fractional lasers rarely leave pigmentation.
After treatment, the small wound on the epidermis will heal completely within 8 hours, and you can wash your face and bath; after 3-6 days of treatment, the crust at the leukoplakia begins to fall off, and the skin begins to return to its normal appearance. The internal collagen regeneration can last up to 6 months or even 6 years. In the short term, patients may feel that the improvement is not obvious, but the long-term effect is very obvious.
Contraindications of CO2 fractional laser：
1.Those with scar constitution;
2.People with mental illness;
3.Active vitiligo or psoriasis, systemic lupus erythematosus;
4.During pregnancy or breastfeeding;
5.People who are sensitive to light;
6.He has taken isotretinoin in the past year and is or has been infected with active herpes lip or herpes simplex virus;
7.If you have had other laser treatments within three months, you should tell the doctor truthfully, and the doctor will assess whether you can receive the new laser treatment.
Precautions for CO2 fractional laser：
1.CO2 fractional laser treatment has fast wound healing, and most patients do not need special skin care. Before removing the scab, they only need to avoid contact with water to prevent infection;
2.Avoid spicy and fishy foods. Light diet;
3.Avoid the sun, do a good job of sun protection, and reduce the chance of pigmentation after inflammation, especially for people with dull skin;
4.After the scab falls off, apply a facial mask and medical moisturizing cream every other day.
CO2 fractional laser has a strong thermal stimulus effect on the skin, and it has many extended applications for skin problems. Therefore, it can effectively solve the following problems:
1.Depressed scars: Acne marks caused by acne, tissue defects caused by trauma, under the action of CO2fractional laser, new collagen fibers and other living tissues are produced, which can fill the small “pits” in the skin depressions. “;
2.Mild hyperplastic scars and stretch marks: Scars are hyperplastic. There are also stretch marks broken by fiber stretching. We use CO2fractional laser, stimulation, abrasion and skin perforation to inhibit scar proliferation and shrink blood vessels;
3.Hormone-dependent dermatitis: A very thorough and positive effect can be achieved by replacing the skin of the entire face; after such treatment, the customer’s skin will have very serious acne. Through gentle and active repair, it is possible to achieve effects that other low-intensity lasers cannot achieve in the treatment of hormone-dependent dermatitis;
4.Treatment of acne itself: The thermal effect of CO2fractional laser has an excellent effect on treating acne, closed acne, and killing Propionibacterium acnes. At the same time, it can also improve acne marks and comprehensively improve skin quality;
5.Oil control and pore shrinkage: Long-pulse infrared laser (CO2fractional laser belongs to this category), can effectively control oil, shrink pores, and have a good therapeutic effect on perioral dermatitis;
6.Pigmented moles: To treat pigmented moles, use the CO2fractional laser “cutting head”, also known as “cutter head”, using pulse or ultra-pulse method, the skin does not bleed during the treatment, the vision is good and clear, the efficiency is high, and the customer feels less pain;
7.Proliferative skin diseases such as age spots, flat warts, xanthomas, and fat granules. Through the CO2fractional laser, these excess pathological tissues are vaporized and ablated.
There are many applications of CO2 fractional laser, but everyone must fully grasp its essence and clinical experience, and then slowly explore.
