If I got lip injections in my lips 6 hours ago is it okay to do cardio?

Dear dnlmedina1994,if you were my patient, I would recommend you to wait at least one day before you continue your exercises. If you start too early with cardio, you risk worsening of your swelling. If you have any concerns, you can consult your injector.Daniel Barrett, MD, MHA, MS

Thank you for sharing your question and congratulations on your lip augmentation!  Swelling after filler placement into the lips is quite common due to the thin nature of the tissues.  This swelling will only worsen with exercise and I would avoid cardio for at least a day's time.  To try and reduce the swelling use cold compresses to your lips and elevate your head at night with a couple of extra pillows behind your back.  You may want to also consider using Arnica Montana and bromelain as supplements.  Hope this helps.
