CO2 Fractional laser

Treatment overview

The technology of this device is a state of the art development in the laser technology applied in dermatology – optical fibre laser built from glass fibre, which creates a stream of microscopic-diameter impulses, distributed on the skin evenly by the scanning head, just like a spray. The effect is rejuvenation of skin with sun damage, smoothing of wrinkles and scars without causing visible wounds with a long period of painful treatment.

Unlike the lasers applied so far, it does not expose or evaporate the skin surface in a uniform manner, but “perforates” it with thousands of microscopic columns, leaving around the “well of burns” a grid made up by islands of healthy, undamaged skin. Thanks to this, the healing process progresses very fast and does not involve creation of a visible wound.

Is this a painful treatment?

In case of impulse energies above 10 mJ, one gets a feeling of unpleasant formication. In case of higher energies, application of anaesthetic cream (EMLA) at least 1 hour before the procedure completely eliminates the pain. In case of highest energies >20mJ and large areas, local injection anaesthetisation may be applied. Even at the higher energies, the Mosaic laser is much less painful than VPL.

When does the effect appear and how long does it last?

Most patients notice an improvement in skin quality already a few days after the treatment. To a large extent, this is likely to be caused by certain swelling, which conceals the wrinkles and scars. This is not the final effect of the treatment – the skin takes little time to damage, but the processing of collagen needs time, from 2 to 4 weeks. Then, lasting renewal effects are visible. Skin reconstruction will be visible perfectly 4-5 weeks after the end of the series of 3-5 treatments. However, collagen reconstruction will continue, causing the smoothing and firming of skin for 6-12 more months after the treatment.

Changes in the epidermis and in the collagen contained in the dermis, caused by the treatments, are permanent. Objective tests have demonstrated that positive changes caused by the treatments do not disappear 6 months after the treatments. However, sunlight, gravity and the time do their job and no device can stop the passage of time, even though the laser can take it back, in fact many seasons back.

Therapy schedule

During a single treatment, the laser affects only 10-20% of the selected skin area. Full regeneration of the skin and final effects will be achieved after a series of 2-4 treatments. A single treatment with a fractional ablative laser provides an effect comparable to 4-5 non-ablative treatments.

Post-treatment recommendations

Redness and slight swelling appears on the skin after the treatment. Temporary rash may also develop, as it is in the case of allergies. Skin looks like after excessive sunbathing, with all effects typical for that, which pass after several hours – which happens the sooner the more consistently we apply all products used in case of sunburns.

Redness disappears after 3-5 days, whereas the swelling increases after 2 days and disappears after 3-4 days. Afterwards, the skin gets somewhat brownish and exfoliates. After a week, the skin regains its normal appearance. If an injection anaesthetisation is applied, temporary bruises may appear at the place of injection.

Very rarely, in case of the highest powers, blisters may develop scabs while healing. If oral anaesthetics were administered to the patient, the patient may not drive a car until the next day. Otherwise, the patient may return to regular activity immediately after the treatment, while avoiding the sunlight and hot baths.
