TMZ has obtained photos of Michael Lohan's slash wounds on his neck and arm -- which he claims he suffered during an attack outside of his Santa Monica home late last night.

Michael claims his attacker used a "sharp object" to slice through his flesh. Judging from the overlapping scratches on his neck -- the suspect either took two swipes at Mike's head ... or used two sharp objects.

So far, the suspect is still on the loose. Cops are investigating.
