During your initial visit, the number of units injected is an estimate to temporarily weaken the targeted muscles. Our approach is to start with a conservative amount especially on your first visit since it's easier to add more if needed than to reverse the effects. Please allow at least 14 days after the injection to evaluate if additional treatments are necessary. This follow-up visit helps us gauge your response to the neurotoxin, make any necessary adjustments, and document your treatment for future reference. Neurotoxin injections are a technique-sensitive treatment. You can trust that licensed, trained, and expert practitioners in facial anatomy will deliver subtle results, so you'll look like yourself—just with fewer noticeable lines. The goal is natural-looking results that no one can easily detect.
