What kind of doctor can remove a skin tag on my eyelid that's in my lashes?

An MD/DO Eye Doctor: Probably an ophthalmologist. They are most often comfortable operating about the eye. But often a skin tag can just be snipped off and it will not come back. This needs to be done “just right” not too deep (you might end up with a notced eyelid margin and not too shallow (it could grow back).

Several options: Ophtahlmologist, plastic surgeon, facial plastic surgeon--check around.

Oculoplastic surgeon: Oculoplastic surgeons are expert in eyelid surgery and frequently remove all types of eyelid lesions.

Skin tag: Your best bet would be to have your eyes evaluated by a board certified facial plastic surgeon.
