Where tox works.

The 11s are the two vertical lines between your eyebrows, named for the parallel “11” they form when you frown. They show up when you concentrate, squint into the sun, or read a difficult email. Over time they can settle in and stay visible even when your face is at rest.

Two small muscles are responsible: the corrugators, which pull the brows together, and the procerus, which pulls them down. A few precise injections relax those muscles so the area stops pinching. The lines soften over the following days, and the tense, stern look between the brows eases.

You’ll still be able to raise your brows and frown, and you’ll still look like yourself. The glabella is the most common place people start, and it’s often done together with the forehead.

The forehead lines are the horizontal creases that appear when you raise your eyebrows, whether in surprise, attention, or just to lift a heavy brow. They run across the width of the forehead and deepen with the same expressions repeated over years.

One broad muscle, the frontalis, lifts the brows. It is the only muscle that does so, which is why we dose the forehead with care. Relaxing it softens the lines while leaving you enough movement to look natural and avoid a heavy or dropped brow.

The forehead is almost always done with the 11s. Relaxing one muscle while the one next to it keeps pulling can look uneven, so doing both keeps the upper face balanced.

Crow’s feet are the fine lines that fan out from the outer corners of your eyes when you smile or squint. They are one of the first areas people notice, and since they come from smiling, we soften them and leave some of the movement.

The muscle is the orbicularis oculi, the ring of muscle that circles the eye and closes it. A small amount placed along the outer edge relaxes just that part, so the skin creases less when you smile and your eyes still move naturally.

It’s a delicate area, so we use a light hand.

A lip flip is a small change. A tiny amount placed along the border of the upper lip relaxes its edge, so the lip rolls slightly outward and shows a little more when you talk and smile.

The muscle is the orbicularis oris, the ring of muscle around the mouth. It doesn’t add volume the way filler does, and nothing is injected into the lip itself. It changes how the upper lip sits, which can also ease a lip that disappears when you smile.

Because the dose is so small, the effect is gentle and tends to wear off sooner than the other areas. It’s an easy area to try.

The DAOs are a pair of small muscles that pull the corners of the mouth downward. When they are active, they can give the face a subtle downturned or unhappy look at rest, even when you’re in a good mood.

Relaxing them releases that downward pull, so the corners of the mouth settle in a more neutral, rested position. It’s a small change to your resting expression.

The mouth corners are often treated alongside the chin, since the muscles in the lower face work together. We keep the doses small and balanced.

The chin can take on a dimpled, pebbled texture, sometimes described as an orange-peel look, when the muscle underneath is active. It tends to show when you speak or press your lips together.

The mentalis is a small muscle that pushes the chin pad upward. A little placed in the right spot relaxes it, so the surface of the chin smooths out and the dimpling settles.

It’s a small, quick area on its own, and it’s often done with the mouth corners to keep the lower face balanced.

The masseter is the large, powerful muscle at the back angle of the jaw that closes your mouth and does the work of chewing. In some people it is naturally strong or overworked, which can widen the look of the lower face and is often associated with jaw tension and grinding the teeth.

Relaxing the muscle eases that tension over time and can soften the line of the jaw. This is a larger muscle than the others on this page, so it takes more product and the effect builds more slowly than in the other areas.

Whether the jaw is a good fit depends on your anatomy and what you are noticing. We’ll talk it through at your appointment first.

The platysma is a broad, thin sheet of muscle that runs across the front of the neck. As it tightens with age or tension, two vertical cords can begin to stand out down the neck, most visible when you talk or hold your jaw firm.

Placing small amounts along the bands relaxes the muscle, so the cords soften and the neck and jawline read a little smoother. We approach it conservatively and build up gradually.

The neck is usually a later step, once you’re comfortable with how your face areas have gone.
