CO2 Laser for Acne Scars: MORE-XEL Scanning | MENDEL CLINIC

CO2 laser resurfacing is one option doctors may consider for selected acne scars and uneven skin texture. This guide explains fractional CO2 laser with MORE-XEL Scanning, preparation, recovery and questions to discuss before treatment at MENDEL CLINIC.
What is fractional CO2 laser?
Ablative CO2 resurfacing removes treated surface tissue and heats the underlying skin, stimulating repair and collagen production. Fractional treatment distributes energy into microscopic areas while leaving intervening skin untreated to support healing. It may improve selected acne scars, fine lines and uneven texture. Several sessions may be needed; complete scar removal is not guaranteed. [1]
About MORE-XEL Scanning
BISON Medical describes MORE-XEL Scanning as a scanner-type fractional CO2 laser operating at approximately 10,600 nm. [2] The device name alone does not predict an individual outcome. Settings, treatment area and recovery requirements must be tailored by a doctor.
Is CO2 laser suitable for my acne scars?
Scar shape, depth, skin tone and medical history matter. A consultation helps establish whether resurfacing is appropriate and whether another approach should form part of the plan. Improvement develops gradually, so follow-up photographs should be assessed after recovery rather than treated as an immediate final result. [1,3]
Preparing for treatment
- Tell your doctor about cold sores, raised or keloid scars, medical conditions and previous skin procedures.
- Discuss all medicines, including isotretinoin, and skincare products. Do not stop prescribed medication yourself.
- Report active irritation, wounds or infection in the treatment area.
- Ask about pain control, recovery time, total costs and realistic expectations. [3]
Recovery and aftercare
Recovery depends on treatment intensity, area and your skin's response. Redness, swelling, stinging, peeling or crusting can occur. Follow the individual wound-care plan, avoid picking or scrubbing, limit sun exposure and resume sunscreen and other products when your doctor advises. Contact the clinic if pain or redness worsens, pus develops or healing appears abnormal. [3]
Potential risks
Risks include darker or lighter pigmentation, infection, cold-sore flare-ups and scarring. Darker skin is more prone to pigmentation changes. A medical assessment is essential to weigh the potential benefits against these risks. [1,3]
Individual treatment photographs
The following photographs show individual cases. Results vary. Lighting, camera angle and timing can affect comparisons. These images alone do not establish the number of sessions, follow-up duration or whether all changes resulted from laser treatment alone. The Thai captions state that results differ between individuals and a doctor should assess suitability.



Frequently asked questions
Are CO2 laser and fractional CO2 laser the same?
CO2 identifies the laser type; fractional describes how treatment is distributed across small areas. Ask which treatment pattern is appropriate for your skin.
Will one session remove my acne scars?
No result can be guaranteed. More than one session may be needed, and complete removal should not be assumed. Discuss goals and reassessment with your doctor. [1]
How many days of downtime should I plan?
There is no single recovery period for everyone. Ask for an estimate based on the planned settings and treatment area, including when to resume makeup, skincare and usual activities.
How much does CO2 laser cost?
Cost depends on the area, skin concerns and treatment plan. Request an individual quotation and clarify what is included before booking. No package price is specified in this article.
