FRACTIONAL LASER CO2
What is Fractional CO₂ Laser and how does it work on the skin?
Fractional CO₂ Laser is one of the most effective and popular treatments for skin renewal and rejuvenation, essentially representing an advanced Laser Skin Resurfacing technology that “recreates” the skin.
It works by emitting microscopic beams of thermal energy that penetrate fractionally (in small columns) into the deeper layers of the epidermis. This technique creates tiny zones of controlled thermal damage (micro-ablative columns), leaving the surrounding healthy skin untouched.
This process achieves:
- Vaporization of damaged, aged skin cells
- Activation of the natural healing mechanism, strongly stimulating fibroblasts to produce new collagen and elastin
As a result, the skin is restructured from within, with a significantly shorter recovery time compared to older, fully invasive lasers.

Which areas can Fractional CO₂ Laser be applied to?
Fractional Laser is versatile and can be applied to various areas of the body where imperfections or signs of aging are observed:
- Face (for wrinkles, imperfections, discolorations, acne scars)
- Neckline (for fine lines, wrinkles, and tightening)
- Hands (for spots and a more youthful appearance)
- Body (for stretch marks on legs, thighs, buttocks, abdomen)
Which skin issues does Fractional CO₂ Laser effectively treat?
Fractional Laser is considered one of the most powerful tools against aging and skin imperfections, as it achieves complete skin resurfacing. It successfully addresses:
- Wrinkles and Fine Lines (especially around the mouth and eyes)
- Scars (from acne, injuries, or surgical procedures)
- Signs of Photoaging (spots, freckles, discolorations, melasma)
- Enlarged Pores and uneven skin texture
- Sagging and loss of firmness
- Stretch Marks
What are the advantages of Fractional CO₂ Laser compared to other methods?
The technology of Fractional CO₂ Laser offers many advantages, which are as follows:
- Impressive and Complete Skin Resurfacing: Stimulates the production of collagen and elastin, resulting in smoother, firmer, and more youthful-looking skin.
- Reduced Recovery Time: Leaves untreated areas of skin intact, allowing faster healing and immediate return to daily activities (usually within a few days).
- Non-Surgical and Safe Procedure: Performed in-office, minimally invasive, and completely safe when applied by a specialized physician.
- Visible Results from the First Session: Improvement is noticeable immediately and continues for months as collagen is gradually produced.
- Wide Range of Applications: Simultaneously treats multiple issues (wrinkles, scars, pigmentation spots).
Is Fractional CO₂ Laser treatment painful?
No, Fractional CO₂ Laser treatment is not painful. Before starting, a topical anesthetic cream is applied to the treatment area for about an hour to ensure complete comfort. During the procedure, the patient may feel a mild burning or warming sensation, which is fully tolerable and temporary.
How many Fractional CO₂ Laser sessions are needed and how often?
The number of required sessions depends on the nature and severity of the condition being treated, as well as the protocol chosen by Dr. Konstantinos Floros:
- Number of Sessions: Usually 3 to 4 sessions are required for overall skin resurfacing and wrinkle improvement. For more severe issues, such as stretch marks, 4 to 6 sessions may be needed.
- Frequency: Treatments are typically repeated every 3 to 4 weeks. Each session has a cumulative effect, enhancing the final result.

What is the recovery time after Fractional CO₂ Laser?
Thanks to fractional photothermolysis technology, recovery time is dramatically reduced:
- Immediate Symptoms: After treatment, noticeable redness and mild swelling may occur, which gradually subside.
- Duration: These symptoms usually last 2 to 6 days.
- Return to Work/Daily Activities: Daily activities can usually be resumed within a few days. The skin achieves a smoother and more radiant appearance within 1–2 weeks.
- Final Result: Collagen production peaks at 3–6 months, achieving the final result in terms of tightening and elasticity.
How can I ensure the best possible results with Fractional CO₂ Laser?
- Post-Procedure Care: It is essential to use high SPF sunscreen (SPF 50+) when exposed to sunlight, as well as moisturizing/regenerative creams as recommended by your physician.
- Combination Therapies: For even more impressive results, the treatment can be combined with PRP (Platelet-Rich Plasma), which naturally enhances skin resurfacing and collagen production.
