Moles are small, coloured spots on the skin. Most people have them and they’re usually nothing to worry about unless they change size, shape or colour.


Renu Skin Clinic are proud to be the only clinic in Tayside to use this method of mole removal without the need of any stitches leaving a scar. At Renu we are always at the forefront of technology and invest heavily to make sure our patients get the best results with the best outcome and less side effects.

Mole removal using electrosurgery generally occupies a place on the electromagnetic spectrum from 350 Khz to 1.7 Mhz. The lower the Mhz, the more lateral tissue damage produced with tissue incision. In electro surgery, the electrode tip provides the resistance during ablation. The tip heats up and significant heat is tranferred to the target tissue. This heat also affects the surrounding normal tissues, resulting in lateral tissue damage that can produce scarring. 

Radiowave surgery operates at a frequency of 4.0 Mhz, which is about 4 million cycles per second.This is the optimum wavelength for precise incision with minimal lateral tissue damage. The reason that radiowave surgery is much more tissue friendly than electrosurgery has to do not only with the 4.0 Mhz wavelength but the fact that the electrode tip does not provide the resistance and hence does not get hot. It is the tissue that provides the resistance. Radiowaves are transferred to tissue through an electrode.

Radiowaves cause a pro cess known as intracellular volatiliztion whereby steam is produced in the cells, causing them to rupture. An- other difference between radiowave surgery and electrosurgery is the ground plate. With electrosurgery, it is possible to shock or burn the patient. Radiowave surgery does not employ a ground plate but rather an antenna that gathers the radiowaves and channels them back to the machine. The antenna, which does not need to be in direct contact with the patient, is Teflon coated so it cannot shock or burn the patient.

Pre procedure Mole Removal

The areas are marked with a surgical pen and then the administration of lidocaine 2% lidocaine infiltrated subcutaneously around the base of lesion for complete numbness. An antenna device will be placed close to the area we work on to avoid any shock or burn.

After the procedures, lesions are covered with a triple an ointment for the next four to five days. The lesion will undergo re-epitheliali- zation over the next seven days. By 30 days, the lesion is often indistinguish- able from surrounding skin.

Many patients are interested in removing moles or skin tags, particularly if they reside on the face or visible skin areas including the neck. However, the thought of a scar can sometimes be the barrier stopping them from making that step. Renu Skin Clinic  are proud to offer a no-scar technique using the latest laser technology to remove moles and skin tags without the need for incisions or stitches.

At the first consultation, we take a full medical history of the moles.  We then use foto finder to image moles at 20x magnification. We also carry out 3 other checks such as the 7 point checklist along with the photographed images.

The images are then studied in detail and discussed with yourself. Your photographs are then stored securely which enable any new or changing lesions to be more easily identified during future consultations.

We provide you with a copy of the images and the result via email.

Should we find any suspicious moles and a diagnosis of skin cancer we will contact your GP with a report be for  the best course of action.

Moleanalyzer pro impressively visualizes colors, borders, symmetry axes, structure and network of your lesion.

Some moles can be a sign of melanoma, a type of skin cancer.

Signs of melanoma include:

A mole that’s changed colour or has more than 2 colours

A mole with uneven borders

A mole that’s bleeding, itching, crusting or raised

Therefore it is important to get this checked.

It’s important to get a new or existing mole checked out if it:

  • changes shape or looks uneven
  • changes colour, gets darker or has more than 2 colours
  • starts itching, crusting, flaking or bleeding
  • gets larger or more raised from the skin

These changes can happen over weeks or months.

If at you’re a appointment we think it’s melanoma or anything suspicious  we will send your report and photos to your GP that same day and  you’ll be referred to a specialist in hospital.
