The vast majority of moles are normal, however if you notice changes in the colour, height, size or shape of a mole, then you should consult the advice of a dermatologist. You also should have a mole checked if it has been bleeding, itching or has become tender or painful.
Local anaesthetic is generally applied to the treatment area, however the exact technique of removing a mole depends on the condition and its location. These include:
- Freezing with liquid gas
- Shaving the mole close to the skin using a surgical blade
- Using a chemical such as salicylic acid
- Punch biopsy
Although great care is taken to minimise scarring, mole removal treatment may leave a small scar once the wound has healed. When a mole is removed, it should be protected using an SPF 30 sunscreen or above for at least 6 months. It is also vital the wound is kept clean and covered to avoid infection while it heals.
