Icing after restylane helps with swelling ,minimizes bruising and helps with the discomfort. Most of the swelling will subside in a few days. Maintaining a low salt intake is also helpful.
The best inflammation and swelling are those that NEVER took place. Icing or freezing before (see Zimmer air chiller), proper injection technique and icing after gives the best result. In addition, use of short doses of CELEBREX (in NON Sulfa allergic patients) prevents swelling. You need to discuss it with your injector - hopefully a doctor.
