Contouring the Face With Filler and Neuromodulator Together

A 2019 paper by two Spanish clinicians describes how they plan facial contouring using hyaluronic acid filler and botulinum toxin type A together, starting from the overall shape of the face. Its main message for patients is that good contouring begins with assessment and proportion, not with a single wrinkle or feature. It is a practical guide based on the authors' experience, not a trial, so it describes an approach rather than proving it works better than others.

Why this was studied

Filler and neuromodulator do different jobs. Filler adds volume or support where tissue has thinned or where structure is lacking. Neuromodulator relaxes specific muscles, which can soften expression lines or, in the case of the large jaw muscle, slim a bulky lower face. Our article on filler vs neuromodulator explains the difference.

Because both treatments are now widely used, clinicians have looked for structured ways to combine them so that results look balanced. The authors wanted to share a step-by-step method for doing this, aimed at other specialists.

What the authors describe

The approach starts with a medical history, including questions about bleeding problems, uncontrolled high blood pressure and blood-thinning medication, followed by an examination, photographs and video of the face in motion. Goals are agreed with the patient before any plan is made.

The authors then sort faces into broad shape categories, such as round, square, triangular, inverted triangle, rectangular and long. Classic proportion checks are used too, such as dividing the face into horizontal thirds and vertical fifths and looking at the profile line from nose to chin. Each shape gets a different strategy. For example, a square face might combine jaw-muscle relaxation with filler that adds projection at the cheeks and chin, while a long face might focus on the temples and the sides of the face to reduce the sense of length.

The paper also describes matching filler firmness to depth: firmer products placed deep against bone for structural support, medium products in the middle layers, and soft products for fine areas such as around the eyes and lips. Injection points are planned using a structured injection-mapping system, an approach several clinicians use to keep treatment consistent.

What they report

The paper illustrates its method with four example patients but does not say how many people were treated in total or measure outcomes with rating scales. The authors report that side effects in their practice were uncommon and mild, mainly swelling, redness and bruising that settled without lasting problems. They stress careful patient selection, sterile technique, detailed knowledge of anatomy and early recognition of blocked blood flow as the foundations of safety. They also note the method is not designed for people with moderate or severe facial asymmetry.

How strong is this evidence?

The journal classifies this paper at a lower level of evidence: it reflects expert experience rather than a controlled comparison. That kind of paper is valuable for sharing techniques and reasoning, but it cannot show that one approach produces better or safer results than another. Points to keep in mind:

• No measured outcomes. Results are shown as examples rather than counted or scored.
• Personal experience. The authors themselves say their results should be read in that light and call for good-quality prospective studies.
• Industry support. The first author reported a grant from a product manufacturer to cover writing costs, although the company said it did not influence the conclusions.

Face-shape categories are also a simplification. Real faces rarely fit one box, and personal, cultural and gender preferences all shape what "balanced" means to an individual.

What it means for you

The most useful takeaway is the order of thinking. A careful plan looks at your whole face, your proportions and how your face moves before deciding where, or whether, to treat. It aims to work with your features, not to make everyone look alike. Our article on combination treatment plans covers why one treatment rarely addresses everything.

Combining treatments also means combining risks. Filler can cause swelling, bruising, lumps and, rarely, a blocked blood vessel, which needs urgent treatment. Neuromodulator can cause bruising, headache and, uncommonly, temporary drooping or changes in expression if it affects nearby muscles. Both are avoided during pregnancy and breastfeeding, and some medical conditions and medications need to be discussed first. Never stop a prescribed blood thinner without speaking with the doctor who prescribed it.

Treatments are often staged over more than one visit, which allows swelling to settle and results to be reviewed before more is added. In some cases the honest advice is that less, or no treatment, is the better plan.

It also helps to know that the two treatments behave differently over time. Neuromodulator effects typically appear over one to two weeks and fade over a few months, while hyaluronic acid filler usually lasts longer and fades gradually. A combined plan therefore often involves different review and maintenance schedules for each part.

Questions to ask at your consultation

• What do you see as the main reason my face looks the way it does: volume, muscle activity, skin or bone?
• Would you stage treatment, and what would each visit aim to do?
• What are the warning signs of a serious complication, and how do I reach you if I notice them?
• What would happen if I chose to do nothing?

Frequently asked questions

Can filler and neuromodulator be done on the same day?

Sometimes, depending on the areas and the plan. Some clinicians prefer to separate them so each result can be judged on its own. Your clinician will explain the reasoning for your situation.

Does knowing my face shape tell me what treatment I need?

Not on its own. Face shape is one starting point among many, alongside skin quality, symmetry, movement and, most importantly, your own goals.

Is a combination approach right for everyone?

No. Some people are best served by a single treatment, skincare, or no treatment at all.
