A mole is a benign proliferation of pigment-producing cells. Most are exactly what they appear to be — but appearance alone cannot separate the ones that are from the ones that are not, and every method of removing one destroys the tissue that could have answered the question.

A melanocytic nevus, a seborrhoeic keratosis and a skin tag can all present as a raised pigmented lesion, and they are managed differently. Destroying a lesion by any means eliminates the tissue that would otherwise be available for examination — so the sequence at IN Eternity is assessment, then method.
A 2026 systematic review pooling 46 studies and 4,201 lesions compared the approaches directly. Surgical excision produced the highest clinical clearance at 96.4% and the lowest recurrence at 2.1%. The non-surgical methods sat well behind: CO2 laser recurred in 12.9% of cases, Er:YAG 14.3%, electrosurgery 16.1%, dermabrasion 22.7%.
The same analysis scored appearance, and the ranking inverted. Er:YAG rated highest at 8.8 out of 10, CO2 8.4, shave excision 7.6, surgical excision last at 6.2. That inversion is the whole decision in one line: the method that clears most reliably leaves the most visible mark. Which trade-off is right depends on the lesion, its depth, its site and your skin type — not on preference alone.
Home removal kits, thread ligation and cauterising pens. They risk infection and scarring, they frequently leave nevus cells behind, and they permanently remove the option of examining a lesion that turns out not to have been a simple mole. Treating a changing lesion cosmetically is the other failure — change is a reason to examine, not to remove.
“A mole is not a cosmetic object until it has been examined. Vaporising a lesion removes the pigment and the evidence in the same pass — and only one of those grows back.”
We use both excision and laser at IN Eternity, and the choice is made after looking properly, not before. If a lesion is straightforwardly benign and sits somewhere a linear scar would be conspicuous, laser is a reasonable choice and the satisfaction data explain why patients prefer it. If anything about the lesion warrants histology, it is excised and sent, and the cosmetic conversation waits.
Yes, and this is the step that matters most. Removal by any destructive method eliminates the tissue that would be available for histopathology. Assessment establishes whether the lesion is a straightforward benign nevus suitable for a cosmetic approach, or whether it needs excision with the specimen examined.
They answer different questions. Excision had the highest clearance and lowest recurrence in a 46-study meta-analysis; laser scored highest on cosmetic satisfaction. Ablative approaches reach a limited depth, so recurrence is higher, particularly for intradermal lesions.
Because ablative lasers vaporise tissue to a limited depth and nevus cells sitting deeper in the dermis can remain. Reported recurrence is 12.9% for CO2 and 14.3% for Er:YAG, and higher again for intradermal lesions.
Every method leaves something. Excision produces a linear scar and the most reliable clearance. Ablative and shave methods generally produce a better cosmetic result and a higher chance of the lesion returning.
Recent change in size, colour, border or symmetry; bleeding, itching, or a lesion that has newly become raised. Also a personal or family history that raises the index of suspicion.
No. Number, site, depth and whether histology is indicated all affect this, and it is established at assessment rather than promised in advance.
Every assessment at IN Eternity Clinic is carried out personally by Dr Sin Yong. If the honest answer is that treatment should wait, you will be told that.
