If you are actively swelling, you may have an initial increase in swelling and then it will resolve. Enjoy your infared sauna, they offer many health benefits.
Thanks for the question. Typically, I wait two weeks before re-injecting an HA filler in the treated area. Non-HA fillers can be injected after the inflammation has resolved from the hyaluronidase which is typically a few days. I hope this helps!
