FAQ about
Fractional CO2 Laser
IS CO2 LASER SAFE?
Laser resurfacing is a minimally invasive treatment with a low complications rate as long as it is performed by a dermatologist with several years of experience in this type of treatment.
HOW MUCH DOES CO2 LASER COST IN LISBON?
The price of a fractional CO2 Laser treatment will depend on the facial areas to be treated and the number of sessions required. During the medical appointment, a treatment plan will be presented with the respective cost for your specific case.
IS THE TREATMENT PAINFUL?
CO2 Laser is a quick treatment and discomfort is minimal and brief – an anesthetic cream is applied 30 to 60 minutes before treatment to minimize the associated discomfort.
HOW QUICKLY WILL RESULTS BE NOTICEABLE?
Two to three days after the treatment, small scabs will appear and then fall over the days. The skin will go back to normal 10 to 15 days after the treatment, at which point it will be possible to see the improvement in its appearance.
HOW LONG DO CO2 LASER RESULTS LAST?
As the result is due to the stimulation of collagen production during healing and an increase in skin firmness, there is no time limit for the results. The skin continues its natural aging process, but from a better condition. Several sessions of CO2 laser can be performed, thus achieving progressively improved results.
CAN PEOPLE WITH DARKER SKIN UNDERGO CO2 LASER TREATMENT?
There are some restrictions for higher phototypes (darker-skinned patients). As the laser light targets the pigment that conveys color to the skin and hair, patients with darker skin are at risk of absorbing more of the laser light, thus suffering skin burns. Specific skin conditions should be evaluated by the dermatologist.
CAN THE TREATMENT BE PERFORMED AT ANY TIME OF THE YEAR?
Fractional CO2 Laser should be performed during autumn/winter, as in summer it is more difficult to avoid sun exposure and heat, and the treated area becomes more fragile and subject to related complications.
WHAT ARE THE SIDE EFFECTS ASSOCIATED WITH CO2 LASER TREATMENT?
CO2 Laser is usually well tolerated and complications are rare. However, in the first days after treatment, swelling and redness may occur in the most sensitive areas of the face. These effects are temporary and disappear quickly.
WHAT ARE THE CONTRAINDICATIONS OF FRACTIONAL CO2 LASER?
Laser CO2 has few contraindications and these are common to most procedures:
- Pregnancy and breastfeeding;
- Patients with active acne, being treated with isotretinoin;
