I have swelling under my eyes and on my cheeks(cheekbones). How do I know if it is from Botox or from laser treatment? (Photo)

While your swelling is most likely related to laser treatment, As you are having  a problem shortly after a procedure was performed I encourage you to contact the physician who performed your treatment to get a recommendation for your best options.

this is often due to KTP treatment which can leave swelling for 2-3 weeks if done very aggressive.  I would have some patiences, take Arnika Forte, and use ice packs and head elevation.  If you are concerned, please see your physician .  Best, Dr. Emer.

Don't panic yet. You had two procedures yesterday that will cause your skin to swell. My guess is that your body is just healing. Give it a week and if the redness/swelling hasn't resolved itself, contact your surgeon. Best, Dr. Nazarian

 This is definitely due to swelling from the laser treatment. You do not have herniation of the orbital fat pads.  Although you may have read about pseudo-herniation of the orbital fat pads due to Botox, after nearly 20 years of experience with Botox, I have never seen this complication.  

It appears that you are having swelling from the laser procedure.  You can take an antihistamine or ice the area and it should help the swelling resolve.  The V-Beam usually works best for facial rosacea and does not cause this swelling. Best, Dr. Green
