Hey icecream and thanks for your question!
In my practice I would excise the mole. I would do this for several reasons.
1. we don't know how deep the mole goes - occasionally with shaving some pigment is left behind or recurs over time- the deeper the shave the worse the scar
2. with a small excision using beaver blade scalpels- the entire epidermis and dermis is removed making re-pigmenting impossible
3. A full thickness excision biopsy is the standard of care with any skin lesions that may be concerning for melanoma (able to asses thickness of the tumor) *** your mole doesn't look concerning for that- just information and can't rule anything out by pictures.
4. a tiny excision would be unnoticeable if done by a skilled surgeon
Hope this helps and God Bless!
