Swelling & black under eye 1 month after Botox. What should I do? (photos)

Botox if used under the eye should be injected in very small amounts and in the right candidates.  You don't appear to be a candidate for this type of treatment and it likely was not injected correctly.  I have never seen a bruise that deep or severe from Botox, ever.  Like said on other comments, fillers and/or laser is better for the undereye wrinkles.  Please seek the advice of a cosmetic dermatologist or plastic surgeon with much experience in utilizing toxins, fillers and lasers for various skin dilemmas.

Hi Susan.  It does not look like swelling to us. If the under eye area was injected with Botox, then it's very likely that you have a relaxation of the muscle that surrounds the eye.  This relaxation gives you the appearance of being swollen.   The bottom line is that Botox is not a good product under the eyes and should not be used there.  We much prefer laser resurfacing or Restylane to address lines or volume loss in the same area.  The good news is that the effects should wear off soon, usually within a month or so.  Good luck.
