The author of Microbotox technique, Dr. Woffles Wu, has been successfully using this technique for years to accelerate scar healing as well as to prevent the development of keloids.
He uses injections of Microbotox for already existing keloids in a specific program, as presented in the text bellow.
Keloid scar is still a troublesome issue in all surgical branches, especially in aesthetic surgery, where otherwise excellent results could be compromised by the development of keloids. Keloid can occur due to several factors, which a surgeon can keep under control, e.g. the site of the scar, how and what materials are used to close the wound or whether the wound is or is not immobilised after the procedure. In spite of all this, the keloids may appear nevertheless and therefore spoil otherwise good surgical result.
Most of the scars go through an early stage when the wound is hypertrophic. The stage is typical for several days or weeks after the procedure. It can last even for months. Hypertrophic scar reacts very well to various ways of treatment (silicone gel, creams, massage, corticosteroid injections directly into the scar and even IPL) and can be healed after three-four treatments.
Keloid scar behaves completely differently. It can develop from a hypertrophic scar or appear several months after it has already been healed. The scar elevates fast, it turns ‘angry’ red, hard, very itchy or even painful to touch and overgrows the original scar. Sometimes it stretches into the surrounding tissue (”the advancing edge of the keloid”). Keloids usually react well to the corticosteroid injections, but they reappear again in 3 to 4 weeks. Even after several different therapies (IPL – intensive pulsed light, interferon, radiation, cryotherapy, surgical cuts, 5-fluorouracil, lasers, silicone gel, and compressive clothes) the results were poor.
There are several theories about the appearance and development of keloids. The most attractive one is the one describing the abnormal activities of fibroblasts and decreased cell apoptosis that means higher production and lesser disintegration, which in return brings the increase in growth factor and other cytokines. It is yet unclear why this happens.
Woffles Wu uses triple therapy program for treating the existing keloids. He applies IPL- intensive pulsed light to minimise the redness and blood circulation in the keloid, corticosteroid triamcinolone, which he injects directly into the scar, to level the keloid and then injects Microbotox into the scar and skin around the keloid. It provokes cell apoptosis (death) and decreases tension of myosin in the wound rim and reappearance of keloids. Microbotox works as a ‘’chemical splint’’ in synergy with triamcinolone corticosteroid, so only a small amount of corticosteroid is needed, the keloid redness is smaller and the remission of keloid is slower and less intense.
Triple therapy continues monthly until the keloids are eliminated (4-8 treatments).
If there is a fresh wound after certain surgical procedures (caesarean section, post-abdominal plastic scar, inframammary incision after breast augmentation or reduction, etc.) only Microbotox is used, usually six or seven days after the procedure.
There are no significant side effects.
