About Pitted scar/Acne scar Treatment:
At ROHTO AOHAL CLINIC, we use Fractional CO2 Laser technology to treat pitted scars/acne scars.
The mechanism of the treatment is using a laser beam with a wavelength of 10.600 nm to target both the epidermis and the dermis of the skin. The laser beam is divided into thousands of tiny but deep columns in the skin, called microthermal treatment zones (MTZs). By using the MTZs, the laser only targets and treats intensively within the zone while the surrounding healthy tissues remain intact and unaffected.
The laser beam creates microscopic fake wounds on the skin, triggering the body's natural healing response. The healing response then leads to new collagen formation and collagen remodeling in the treated area.
Therefore, the Fractional CO2 Laser is a great method for stimulating collagen production and resurfacing the skin. The treatment works especially well on pitted scars/acne scars. The ideal treatment interval is once a month. In general, customers will achieve smooth skin, free from pitted scars/acne scars after 3 - 5 treatments (the result may vary, depending on each customer's condition).
About Keloid, Hypertrophic scar treatment:
The main cause of keloid and hypertrophic scar is the over-production of collagen and elastin during the wound healing process.
Keloid and hypertrophic scars usually form after injuries such as lacerations, skin tears, bad tattoos, burns, surgery wounds... or during skin inflammation from acne, skin infections, and insect bites.
Keloid scars and hypertrophic scars often appear as pink/purple distinctive spots or patches on the skin with a smooth and bulging surface.
When the skin is damaged, the recovery process may leave a flat scar on the skin. The scar may become hypertrophic, thickening over time but it is still confined within the edges of the wound. Hypertrophic scar is usually red and it can subside over time.
Meanwhile, keloid begins to appear a while after the skin is damaged and they can spread beyond the wound. Even a tiny injury like an insect bite can cause keloid on the skin. Keloid is especially ugly to look at, causing much discomfort and insecurity for people when having them.
At ROHTO AOHAL CLINIC, we treat keloid and hypertrophic scars by injecting Corticosteroids into the scar. Corticosteroid is a very strong anti-inflammatory agent. Injecting Corticosteroid into the scar will prevent inflammation, reduce the number of fibroblasts and inhibit collagen formation on the scar area, healing the scar slowly yet effectively.
The ideal treatment interval is once every 4 - 8 weeks. It may take multiple treatments (more than 5 times) to achieve the desirable result. Customers should be patient and closely follow the doctor's instructions during the course of the treatment.
