CO2 Laser treatment is a type of laser resurfacing treatment that works by removing thin, controlled layers of damaged skin. It is commonly considered for concerns such as acne scars, rough skin texture, enlarged pores, fine lines, and selected sun-damaged skin changes.
Many modern treatments use fractional CO2 laser technology, which treats the skin in tiny, targeted areas rather than resurfacing the entire surface evenly. This allows the skin to go through renewal in a more controlled way and can support healing as the surrounding skin remains intact.
CO2 laser treatment works by using laser energy to resurface the skin in a controlled and precise way. As the outer damaged skin layers are treated, the skin also goes through a healing response that supports collagen remodelling, which is why the treatment is often discussed for texture-related concerns and selected acne scars.
In simple terms, this is more than a surface-level treatment. It is a doctor-led resurfacing approach that is planned based on your skin condition, the concern being treated, the treatment depth needed, and how your skin is expected to recover.

Face: The most commonly treated area for concerns such as acne scars, uneven texture, enlarged pores, and fine lines.
Cheeks: Often treated when scarring, visible pores, or textural changes are more noticeable.
Forehead: May be suitable for rough skin texture, fine lines, or other visible surface changes.
Perioral Area (Around the Mouth): Treatment may be used to improve fine lines and skin changes around the mouth area.
Neck: May be treated when visible texture changes or sun-related skin damage extend below the face.
Chest and Hands: Can be treated in selected cases where the skin shows visible signs of sun damage or surface ageing.
CO2 Laser treatment may be suitable for individuals looking to improve surface-level skin concerns through a doctor-led laser resurfacing approach. You may be suitable if you:
Suitability is confirmed during consultation, where your doctor will assess your skin type, concern area, treatment goals, and expected recovery profile.
CO2 Laser treatment may not be suitable in certain situations. You may not be suitable if you:
During consultation, your doctor will assess your skin history, current condition, and any relevant risk factors.
Before Treatment
Your consultation begins with an assessment of your skin concerns, treatment goals, medical history, and the area to be treated. This helps your doctor determine whether CO2 laser treatment is suitable and how the treatment should be planned for your skin.
During Treatment
During the procedure, the laser is passed over the treatment area in a controlled and targeted way based on the selected settings. Depending on the treatment intensity, local anaesthesia is commonly used, and the overall experience can vary according to the depth of resurfacing needed.
After Treatment
After treatment, the skin may appear red and feel warm, sensitive, or tight as it begins to heal. Peeling, crusting, or visible recovery may also occur, so following your aftercare instructions closely is an important part of the process.
Aftercare Guidelines
After CO2 laser treatment, aftercare is important to support healing and protect the treated skin. Your doctor may advise you to:
cleanse the skin gently
use recommended post-treatment skincare products
avoid rubbing, picking, or irritating the treated area
avoid direct sun exposure
apply sun protection carefully during recovery
follow your doctor’s instructions based on the depth of treatment and your skin response
Recovery time can vary depending on the treatment settings and how your skin heals. Cleveland Clinic notes that healing may take around 10 to 21 days in many cases, though this depends on the intensity of treatment and the condition being treated.
Short-Term Effects
Short-term effects after CO2 laser treatment may include redness, swelling, peeling, crusting, dryness, tightness, and temporary sensitivity as the skin heals. In less common cases, more significant effects such as infection, prolonged redness, pigment change, scarring, or delayed healing may occur, which is why proper aftercare and follow-up are important.
