Mole removal is usually done in one of two ways. A shave removal slices a raised mole flush with the surrounding skin and leaves a small round mark without stitches. An excision cuts out the whole mole with the full thickness of skin and closes the wound with stitches, leaving a fine line. Excision gives a complete sample and is preferred for any mole with worrying features; shave removal suits some raised, clearly harmless moles.
How shave removal works
After local anaesthetic, a fine blade is used to shave the raised part of the mole level with the skin. The base is treated to stop bleeding, and the wound heals like a graze over one to two weeks without stitches. Because only the upper part of the mole is removed, some mole cells may remain deeper in the skin. The result is usually a small, flat, round mark that may be slightly paler or pinker than the surrounding skin.
How excision works
An excision removes the mole along with a small margin of normal skin, down to the fatty layer beneath. The wound is shaped as a narrow ellipse so it can be closed neatly with stitches, usually leaving a line about three times the length of the mole’s width. The line is positioned along natural skin creases where possible. Stitches are removed after about five to fourteen days depending on the site. The entire mole is sent to the laboratory.
Side-by-side comparison
- Best for: shave: raised, soft, clearly harmless moles, often on the face. Excision: flat moles, larger moles and any mole with unusual features.
- Stitches: shave: none. Excision: yes, sometimes with dissolvable stitches beneath the skin.
- Scar: shave: a small round flat mark. Excision: a fine line longer than the mole.
- Healing: shave: one to two weeks, like a graze. Excision: stitches out in about one to two weeks, with the scar maturing over 12 to 18 months.
- Recurrence: shave: pigment can reappear if cells remain. Excision: recurrence is much less likely.
- Histology: shave: a partial sample that may be harder to interpret. Excision: a complete sample with margins assessed.
- Activity limits: shave: few. Excision: avoid stretching the area for a week or two.
Why excision is safer for suspicious moles
If a mole could be a melanoma, the pathologist needs the whole lesion, including its deepest part, to make an accurate diagnosis and measure its thickness, which guides treatment. A shave can cut through a melanoma, making diagnosis and staging less reliable. For this reason, a mole with ABCDE warning signs, or one that is new and growing in adulthood, is generally removed by excision, often through a specialist skin cancer service. If you are worried about a mole, see your GP promptly.
Why shave removal suits some moles
Many facial moles are raised, soft and flesh-coloured or light brown, and have been present for years without change. In these cases, a shave can remove the bump with a small, flat mark and no line scar, which may be cosmetically preferable. The tissue is still usually sent for histology. The trade-off is a chance that the mole’s colour may partly return, and that a second procedure may be needed.
Other methods you may hear about
Punch excision uses a small circular blade for tiny moles and is essentially a mini excision. Cautery, freezing or laser may be used on some other skin lesions, but they destroy the tissue, so there is nothing for the laboratory to examine. They are generally not appropriate for moles, and home removal kits should never be used.
Which is right for you?
The choice depends on what the mole looks like, where it is and what matters most to you. Mr Nassab will examine the mole, explain which technique is safe and suitable, and show you the likely scar. For a clearly harmless raised mole, you may be offered a choice. For a flat, changing or unusual mole, excision is usually recommended. Mole removal is from £650 with the final quote confirmed after assessment, and the consultation costs £150; cosmetic removal is for adults aged 18 and over.
Frequently Asked Questions
Is excision or shave better for a facial mole?
A raised, clearly harmless facial mole often suits shave removal. Flat or unusual moles are usually better excised.
Can a mole grow back after shave removal?
Yes, some pigment can reappear if mole cells remain. Recurrence should always be reviewed.
Does excision leave a bigger scar?
The scar is longer than the mole, but it is a fine line that usually fades well when placed along skin creases.
Are both methods done under local anaesthetic?
Yes. Both are usually carried out under local anaesthetic, and you can go home straight afterwards.
