CO2 Fractional Laser Face

Fractional CO2 laser resurfacing of the full face targeting fine lines, wrinkles, acne scars, sun damage, and uneven texture. The 10,600nm wavelength ablates microscopic skin columns while sparing surrounding tissue to accelerate healing and stimulate deep collagen remodelling.

The CO2 fractional laser treatment at Ästhetik Institut Berlin uses a carbon dioxide laser operating at a wavelength of 10,600nm — a wavelength that is strongly absorbed by water in the skin — to ablate and resurface the facial skin in a controlled, fractional pattern. Unlike fully ablative CO2 lasers that remove 100% of the treated surface (associated with significant downtime and risk), the fractional mode delivers the laser energy as thousands of microscopic columns of ablation (microscopic treatment zones, or MTZs) separated by untreated bridging skin. This pattern accelerates healing: the intact skin between the MTZs serves as a reservoir of keratinocytes that rapidly resurface the treated columns, reducing healing time from weeks (full ablation) to 5–7 days. Each MTZ is a narrow column of ablated tissue extending from the epidermis into the upper dermis. At the base of each column, a zone of thermal coagulation extends deeper, heating the surrounding dermis to 60–70°C without ablating it. This thermal zone triggers the same wound-healing cascade as RF microneedling — fibroblast activation, growth factor release, and progressive collagen and elastin synthesis over 3–6 months. The combined ablation (surface smoothing) and coagulation (deep structural remodelling) makes fractional CO2 laser one of the most effective single-modality treatments for wrinkles, acne scars, and photoaged skin. The 45-minute session at Ästhetik Institut Berlin includes topical anaesthetic application 45 minutes before treatment. The laser pass is completed in 15–20 minutes, covering the full face including the periorbital and perioral zones. Immediately post-treatment, the skin is red, swollen, and may weep serum. A healing ointment is applied and patients are sent home with detailed aftercare instructions covering wound care, sun avoidance, and moisturisation. Social downtime is typically 5–7 days; makeup can be applied once the skin has re-epithelialised. A single treatment produces noticeable improvement in skin quality. For more severe acne scarring or deep rhytides, a course of 2–3 sessions spaced 6–8 weeks apart may be recommended. CO2 laser treatment is most appropriate for lighter skin tones (Fitzpatrick I–III) due to the risk of post-inflammatory hyperpigmentation in darker skin types; patients with darker tones should discuss alternative modalities with the practitioner.
