Throughout the Face Restylane injections cause no significant pain, swelling, or recovery time. Treatments typically take about 30 minutes. A topical numbing cream is applied prior to treatment. When Dr. Darush injects the lips, he numbs the area with a painless Lidocaine dental nerve block under the lip. Small amounts of Restylane are injected into precise locations, and in most cases you will be asked to give feedback so that you have control over your final look. The result is a soft, pliable filled area, which looks natural. After six to eight months your body absorbs the filler and the injections can be repeated, meaning that the treated area can be adjusted to compliment the changes that occur in your face over time.
