Doctors have warned over the safety of the Microneedle Therapy System.

The Microneedle Therapy System – also known as the Dermaroller – involves the face being numbed with an anaesthetic before it is massaged with a needle studded roller. This process is said to help the patient look younger by helping to improve collagen production in the skin and enhance local blood flow. This leaves the skin with a healthy glow and a more youthful looking appearance.

The major problem with the device is that it is not always sterilised properly between treatments. As the skin is pierced by the needles, if the roller has not been sterilised correctly there is a risk of diseases such as HIV and hepatitis.

Doctors have warned that anyone looking to have the Dermaroller treatment should ensure that they use a reputable salon where there are high standards of hygiene to ensure nothing nasty is picked up from the treatment. Most high end spas will change the roller for each client to ensure there is no chance of cross-contamination.
