I have two "beauty marks" on my lower water line on the same eye. Can these be removed? (Photo)

Your two very small pigmented areas can be removed, laser is one method. Their removal will not have any effect on eyelash growth.

Thank you for your question and photograph. It's difficult to evaluate your skin through this type of forum. Due to the location of the lesions, I highly recommend you consult with an ophthalmologist, eye surgeon/specialist, to evaluate those lesions and determine if they are able to be removed. Take care and good luck.
