In the field of medical beauty, fractional CO2 beauty devices mainly use CO2 lasers (wavelength 10600nm) to precisely treat the skin. Fractional CO2 lasers use segmented laser beams to form micro-treatment zones (MTZs) on the skin, only treating part of the skin surface, accelerating the healing of surrounding healthy skin and reducing recovery time.

Main functions of fractional CO2 beauty devices

1. Skin surface remodeling and rejuvenation

Function: Fractional CO2 lasers use tiny laser beams to form minimally invasive dots on the skin, stimulate the regeneration of collagen and elastic fibers, and promote skin firmness and smoothness.

Specific effects:
Reduce fine lines and wrinkles (such as dynamic lines around the eyes and corners of the mouth).

Improve skin sagging and enhance facial contours.

Enhance skin elasticity and restore a youthful appearance.

Applicable scenarios: Suitable for people over 35 years old or skin with early signs of aging, with a more delicate skin texture after treatment.

2. Treatment of pigmentation and uneven skin tone
Function: Laser can decompose pigment particles in the epidermis and dermis, targeting pigmentation problems.

Specific effects:
Lighten sun spots, age spots and freckles.
Improve post-acne pigmentation (PIH).
Even skin tone and reduce dullness.
Applicable scenarios: Suitable for customers with pigmentation or uneven skin tone, especially in autumn and winter to avoid the effects of sun exposure.

3. Scar repair
Function: Through the micro-creative effect of fractional laser, scar tissue is destroyed and new skin is stimulated to form.

Specific effects:
Repair acne scars (such as depressed scars).
Improve scars left by surgery or trauma.
Reduce hypertrophic scars or keloids.
Applicable scenarios: Suitable for patients with acne sequelae or people with traumatic scars, usually requiring multiple treatments.

4. Enlarged pores and skin texture improvement
Function: Laser stimulates the reorganization of collagen in the deep layer of the skin, shrinks pores and improves skin roughness.

Specific effects:
Narrow pores and improve the problem of large pores on oily skin.
Smooth the skin surface and reduce roughness.
Applicable scenarios: Suitable for customers with oily skin or large pores, especially in the T zone.

5. Removal of moles, warts and other skin tags
Function: The high energy of CO2 laser can accurately vaporize abnormal tissue on the surface of the skin.

Specific effects:
Remove benign moles, flat warts or skin tags.
Treat small tumors on the surface of the skin with accurate results and fast recovery.
Applicable scenarios: Suitable for customers with benign skin tags, and must be operated by a professional doctor to ensure safety.

6. Treatment of other skin wrinkles and keratosis problems
Function: Fractional CO2 laser can provide comprehensive treatment for a variety of skin problems.

Specific effects:
Treat stretch marks or obesity marks (by stimulating collagen regeneration).
Improve skin photoaging (such as rough skin caused by sun exposure).
Assist in the treatment of certain skin lesions (such as seborrheic keratosis).
Applicable scenarios: Suitable for customers who need comprehensive skin improvement, such as those with photoaging or stretch marks.
