The practitioner will apply an anaesthetic cream to your skin for 45-60 minutes before your treatment to numb the treatment area. The treatment involves the Dermaroller being rolled over the problem area to produce thousands of micro-medical needle punctures in the skin. This controlled damage to the skin surface is not deep enough to elicit a scarring response however it will cause the body to have a milder healing response. The nearby tissue is broken down and new elastin and collagen are formed. This way scarring, lines, wrinkles and pigmentation are all gently removed, being replaced over time with new skin. The practitioners can control the depth of needling to achieve the best result – they can go as deep as 1.5mm on the face, which has proven successful in removing scars, and as deep as 3mm on the body. The practitioner will assess how deep they need to go.
