Bumps/bulges under my eyes: is this lymphatic drainage post Botox or something else?

I had Botox performed on my crows feet for the first time a little over 5 weeks ago. I recently noticed when I smile there are what appear to be bumps/bulges under my eyes. It’s not too noticeable in person oddly enough but in pictures really shows up. This is my 3rd time overall receiving Botox (normally forehead and 11’s) but first time treating crows feet. Is this the lymphatic drainage affected by over relaxing the muscle?
