COSMEDICAL® offers the latest in safe, cosmetic medicine. We are part of the well established GP Practice, Healthcare Group Guernsey, and all of our treatments are performed by fully regulated doctors and nurses. Our modern, purpose built clinic is adjacent to our St Martins Surgery and has a discreet side entrance to ensure your privacy.

If you are interested in the most up to date, non-surgical cosmetic treatments, in a safe medical clinic, we would be delighted to help you. We undertake an initial, in-depth consultation and assessment of your skin and learn about your goals, expectations and fears. We can then develop a personalised treatment plan based on what you would like to achieve.

Our opinions will be honest and we will only recommend treatments and products that we have full confidence in.
