CO2 Laser
What is the CO2 Laser?
The Fractional CO2 Laser is a semi-ablative laser that delivers precise light pulses to the targeted area, creating microscopic columns of ablated tissue. These micro-injuries stimulate the natural healing process, promoting collagen and elastin production. As a result, the Fractional CO2 Laser replaces damaged skin with new, healthier tissue, giving it a smoother, more radiant, and rejuvenated appearance.
What is the CO2 Laser used for?
The CO2 Laser is used for facial rejuvenation treatments, as it promotes skin regeneration to address deep wrinkles, age, or sun-related damage, and texture irregularities such as acne scars. This technology is also ideal for rejuvenating the neck, décolletage, and hands.
Benefits
- It regenerates and remodels the skin by stimulating collagen production.
- It promotes smoother, more even skin with improved texture.
- It significantly reduces scars and pigmentation spots.
- It deeply rejuvenates the skin’s appearance by minimizing wrinkles and expression lines.
- It improves the appearance of enlarged pores.

- It enhances the skin’s radiance.
Duration
CO2 Laser sessions can take up to 60 minutes.
The results can be long-lasting, depending on individual factors such as age and post-treatment care. Improvements appear progressively after the procedure.
Application Process
After cleansing the skin, the specialist will apply a topical anesthetic and then use the laser on the targeted areas. The light pulses create controlled micro-injuries that stimulate the skin’s natural regeneration process.
