The Art of the Lip: Why "Migration" is a Myth and What Really Works
Let me take you behind the scenes of a true lip injection. You’ve seen the trends and the hype on Instagram—the gimmicks, the gadgets, and the alarming claims. But what really works? What is safe? I want to share a technique that has proven itself over two decades, and one of my favorite tools for this is Restylane Kysse. It’s a beautiful product, though not the only one. The key isn't the brand; it's the understanding of anatomy and physics.
You’ve heard the term “migration” thrown around. Let me be clear: that is complete nonsense. Fillers do not migrate. What happens is a spillover effect. If you overfill a lip, the filler has nowhere to go. It doesn’t magically float to a different part of your face. Instead, it spills over from the red lip (the vermilion) into the white lip above. So you lose the sharp, crisp border. The lip looks fuller above it, and people say it has "migrated." It hasn’t. It has just spilled over the edge because you’ve put too much volume into a container that can’t hold it.
I need all the nurse injectors and dermatologists out there to stop using the word "migration." Please educate properly. It’s a spillover effect, and we don’t want that.
Understanding the Lip's Capacity
The lip is not a flat, two-dimensional structure. When you put on lipstick, it’s flat, it’s 2D. But when you inject filler, it comes out in three dimensions. It fills up the entire space I am holding in my fingers. That volume pushes upward. When the white lip gets full, it looks like it has "migrated." But it’s just overflow.
You have to understand the patient’s anatomy. Some lips have more room. Look at lips with lots of fine lines and wrinkles—those are more stretchable. They have capacity. You can make those lips dramatically bigger in one session because the tissue can expand. But consider a young Caucasian patient with smooth, thin lips. There is no room. Absolutely no room for that lip to stretch. If you try to make it 30% or 50% bigger in one shot, you can’t. It has to be done in multiple sessions. You are essentially performing a slow tissue expansion—little by little. Those patients are the highest risk for the spillover effect.
The Injection Technique: Where and How
Where you put the needle is everything. When I inject, I am directing the needle tip away from the white lip, going back precisely to the vermilion border. The border is a critical landmark. Some people have it very crisply; some don’t. You can create more definition there. For the top lip, I use a technique where I am injecting in a specific direction. This helps "tent" the upper lip, creating more of an upper lip show. It’s a common technique you’ve seen on social media, but it works when done correctly.
The bottom lip is different. It has two distinct tubes—the right and left tubercles. The injection is designed to enhance those specific structures. You’ve seen those gimmicky videos with dental floss or strings placed between the lips? That is a marketing trick. It’s very gimmicky. Because when you take that string out, the filler can blend and slide across the plane. In that narrow scenario, it might actually shift, but it’s not migrating to a different area; it’s sliding over the bridge. You don’t need that. With proper placement, the filler will fill and flow across those tubercles naturally. I am counting on that to use fewer injections—the top lip needs more pokes, the bottom requires fewer.
Safety: Vessels and Pressure
You’ve seen those ultrasonic devices people use to map out blood vessels. Vessels are tortuous; they snake and twist. Even if you see one at the surface, it will snake deeper. Those devices aren’t that helpful. The real safety lies in technique. Forget the retrograde pull-back. It’s not necessary with proper technique. Never use high-pressure injections. Never stay in one place and inject. I always use very low pressure. As I advance the needle, I am slightly moving it and injecting continuously. The filler actually pushes blood vessels out of the way. One spot never receives fluid for more than a fraction of a second. This prevents vascular occlusion.
And please, understand what you put into your body beforehand. This patient eats a ton of nuts, seeds, omega-3s, and seaweed. She will bleed more and bruise more. All of those healthy Mediterranean fats, omega-3 supplements, and anything that thins the blood should be avoided for about two weeks before any injections. That includes a whole list of foods and supplements.
True Micro-Injections
Watch carefully as I work. You’ll see the plunger barely moves. This is true micro-injection, true nano-injection. Barely anything is placed at any one point. All the injections I’ve done so far haven’t even added up to half a syringe. Why? Because I don’t want to put too much into one spot and then have to rub and massage it away. I want the micro-droplets to land exactly where they belong.
Now, I sit her up to check symmetry. Look at that. The proper outline is there. The vermilion border is sharp and crisp definition. The central tubercle is fuller on the top, the lateral tubercles are fuller on the bottom. Perfect symmetry. That is proper lip injection. No lumps, no bumps. Just a beautiful, natural enhancement. The lips have expanded correctly. There is no spillover because the capacity was respected. The technique was precise.
That is the real art. Not the hype.
