FRACTIONAL NEEDLING RF

A revolutionary method has been developed recently in the field of cosmetic surgery, producing promising results in facial and body skin laxity.

The method is based on the principle of wound healing, which prompts the creation and accumulation of collagen, as well as on scar shrinkage. Multiple fine 1-2 mm long needles are arranged 2-3 mm apart, forming a square patch measuring one by one centimeter. As they enter the skin using radiofrequencies, they create an instant burn around them, measuring just a fraction of a millimeter. As these multiple burns heal, they increase collagen production in the area, while also making the skin firmer as they shrink. So the results are not immediate, but start to show once the wound has healed. The greater the intensity and duration of the treatment that will be applied, the longer the recovery time until the results show.

Treatments of lower intensity and shorter duration are well tolerated without any anesthesia and can be performed at the doctor’s office. However, they must be repeated every 15 days so that the total intensity may be cumulatively reached, for more satisfactory results. The small dots created during application subside in a few days, but can be covered with make-up if they are on the face.

Treatments of higher intensity and longer duration require anesthesia and a longer recovery time. These may be applied on parts of the body, such as the upper arms and the thighs, since the postoperative sites may be covered with clothing.

The main indication for the treatment is skin laxity, however, positive results have also been observed in stretch marks and acne.

The treatment may be individualized depending on the time each patient has at their disposal. If they are prepared for a longer postoperative period, then higher-intensity treatments may be performed. Because the pain is not well tolerated during treatment, local anesthesia is applied beforehand. Ice packs are applied to the skin immediately after treatment to minimize the initial edema and redness. Cortisone cream is then applied for the next few days for faster recovery. About 10 days are required for full recovery in the event of aggressive treatment.

Otherwise, if patients do not have ample time for recovery, lower intensities are used so that the postoperative period is shorter (one-two days). Repeat treatment may be required in this case. The small dots from the needles subside faster. The treatment is well tolerated, and more so if anesthetic cream is applied an hour beforehand. The treatment results are visible in one to two months. The accumulated experience from this technique will help to improve and develop it further, paving the way for promising horizons in cosmetic surgery.
