The Story of the Cheek: Reading the Bone, Crafting the Contour
When you approach the cheek, the most useful thing you can do is forget the skin. Forget the superficial. Instead, think about the bone. The zygoma is not a flat surface—it is a complex, three-dimensional structure, and every face of it faces a different direction. The direction of your injection is determined by the direction of the bone. If you project outward from any given surface, you will get a different result.
Feeling the Surfaces
Let me walk you through what I mean. Imagine a male cheek—often a little stronger, a little more angular, but still relatively small compared to the rest of the face. Trace your finger along the superior aspect of the zygoma. You will feel a slight upward tilt. Just a centimeter lateral to that, the bone faces outward—anteriorly. If you inject here, you project the cheek forward. If you move a centimeter laterally, you project outward. If you move a little higher, you get a slight upward projection. In females, I especially try to stay on that upper surface to create that lift, that upward sweep.
Whenever you think about how to inject, think about where the surface of the bone is. You can feel it easily by running your finger along the contour. Over time, you develop a sense for which direction that bone is facing, but you can always check before you inject. Feel the angle. There is definitely a shift in angle as you move across the cheek, and it is very easy to locate.
The Corner of the Cheek
What I want, from an aesthetic perspective, is to know where the angle of the cheek is. Which direction do I want to change? Do I want to project outward? Anteriorly? Somewhere in between? The first thing I do is feel. I get an idea, with my fingers, where the anterior and lateral surfaces are. Then I feel for the corner between those two. That corner runs parallel to the lateral canthus of the eye.
You can also use a line from the root of the helix to the alar base as a guide. The only problem is you can draw that straight line in multiple ways because it is a curved surface. This is why I moved away from relying too heavily on drawings. I want injectors to feel the shape of the bone itself. That is what really matters if you want to find the beauty point. That point is the junction of three surfaces: an upward tilt, a frontal tilt, an inferior, and a superior lateral. I want my needle to land exactly on that junction. If you struggle at first, you can validate it with that drawing—a string or a straight edge laid across the face will help you start.
The Injection Strategy
When I go in at that point, I aim to be on the lateral side of the junction. I feel for the direction the bone is facing me, and that is where I do my first injection. Then, about a centimeter away, there is usually the attachment point of the facial ligaments. The skin has a weak spot there—it is a very good place to deposit product. Further back, there is less certainty. Studies show that product spreads above and below the zygoma. But up to that point, there is typically another weak spot. You can create that rounded shape.
Now, remember the goal I hold in my mind: the cheek should form the shape of a teardrop or a spoon. The deepest part of the spoon is the area of greatest definition. Then it fades away smoothly. If you only do those strategic injections, you can end up with an empty spoon—too much definition in one spot and nothing next to it. So quite often, you need a little volume there as well. I usually make that decision as I am treating, not ahead of time.
The Upper Cheek Junction
When you look up with your eyes, you can see the junction between the cheek and the eyelid. This area, the lateral lid-cheek junction, is sometimes nice to improve. You can inject right on the periosteum here. I feel for the bone, knowing the eyeball is right there, the orbital rim is right there. This is an injection into the upper cheek, not an eye injection. It is very restorative because the lid-cheek junction makes people look tired or sad, and it appears later in life—unlike the tear trough, which can be common even in children. The volume needed is only tiny, so I save it for later in the treatment.
Anterior Surface Injection
If I were to inject on the anterior surface, I would feel for that surface again. But I would enter at a very different angle. I would not be going in at the same angle as the lateral surface. It is a completely different trajectory.
Blood Vessel Awareness
When it comes to blood vessels, this area is relatively safe if you stick to the bone. Not many large vessels are there to worry about. But we do have the transverse facial artery. It likes to run where it is safer, so it is often underneath the bone, curling up a little toward the front. There is also the zygomaticofacial artery. About one-third of people have a tiny foramen with a little artery that comes out of it. You can sometimes feel a slight indentation there—a flat spot. But remember, 70% of people do not have one, so you can do a quick feel to see if you notice it. Thankfully, the vessel is very small.
Then there is the zygomaticoorbital branch. Think of it like the superficial temporal artery coming down much lower and then curling up toward the orbit. Sometimes it replaces the superficial temporal artery entirely. These patients have no temple artery but a large vessel here. I have found one running right into the eyebrow before. Feeling for pulsation is important. You get these odd changes in size and position of arteries. It is more about size—little vessels can go everywhere, but occasionally one becomes dominant. So you check. You feel.
More immediately, there is the infraorbital artery. It branches off the maxillary artery, runs on the floor of the orbit. The maxillary artery supplies the midface, pharynx, and palate. If you inject into this area, you get very internal issues. The foramen is about here, and vessels run in that direction.
The Asymmetry Question
Big smile again. When she smiles, the greatest bulk of her cheek is here, on the lower side. Here, it is much more bony and empty. This fits nicely with my injection plan. I will stay superior, and I may not even do the anterior injection. The goal is restorative and slightly beautifying—not augmentative. The lateral lid-cheek junction looks fuller on that side. Slight difference.
Would you inject different amounts on different sides? Usually not. Here is an analogy: imagine a shot glass with vodka and Coke. If you have a single and a double, they look the same because the relative difference is small. If you then put a shot into each one, you now have a double and a triple. The difference between them is now the triple. So you can do the same treatment on both sides and actually decrease asymmetry. It is easier than trying to vary volumes. I have 0.6 ccs here—I feel underneath with my finger, feeling the shape of the zygoma. It helps me aim. You will miss the zygoma sometimes if you do not do that. A straight injection can fail to find the bone. This helps me not do that.
