Ice is used to reduce swelling and provide comfort. It has no bearing on the ultimate outcome. Swelling from a Restylane treatment will last a few days and possibly longer depending what part of the face was treated and how much volume was used. The lower eyelid area seems to stay swollen the longest and lips the second longest. Having said that, many of my executives go right back to their work following a treatment. However, it usually requires a little bit of time for the treatment to fully settle down. There is no evidence that the icing cuts this time significantly. Recognize that bruising will make a big difference to the recovery time. If you are taking products that increase bruising, no surprise, you're more likely to be bruised by your treatment. Generally, you can add several more days to your recovery when bruising occurs. Because bruising varies so much, there is no rule of thumb for how long it takes to disappear. It can vary from a microbruise that lasts a day or two to a big shinner that can be with you for 10 days or more. Best advise is to stop medications that can thin the blood like Advil, Aspirin, and many of the herbal products for at least a week before a treatment. If you are not sure if a product that you take regularly thins the blood, ask your doctor. Also, if you on a prescribed blood thinner like Plavix, or coumadin, or even Aspirin, ask the prescribing doctor regarding stopping these medications and don't stop them on your own.
