I’ve been practicing aesthetic medicine for over 20 years, and I’ve seen firsthand how incredible facial fillers can be when used artfully and appropriately. I’ve also seen how common injector mistakes can lead to unnatural or unbalanced results. In this blog, we’ll break down what not to do, discuss what makes for beautiful outcomes, and explain why experience, anatomy knowledge, and a sculptor’s eye make all the difference.

First, Let’s Talk Goals: What Are We Really Trying to Do with Fillers?

When used correctly, facial fillers can:

• Restore volume lost with age

• Enhance facial symmetry and proportion

• Soften wrinkles and folds

• Refine or enhance features such as the lips, cheeks, and jawline

The ideal result? You should look refreshed, balanced, and subtly enhanced. People should say, “Wow, you look great!” but not be able to pinpoint exactly what you did. Think whisper, not shout.

Facial reshaping with fillers is about harmonizing features, not inflating them. Less is often more, and strategic placement always trumps sheer volume.

Lips: More Than Just Volume

Common Mistake: The Duck Look

Lips are perhaps the most requested area for filler, and unfortunately, also the most commonly overdone. The classic mistake? Overfilling the upper lip or filling only the center portion, leading to the dreaded “duck lips” or a sausage-like appearance.

What Often Goes Wrong:

• Over-injection in the vermillion border (the outline of the lip)

• Ignoring the philtral columns and Cupid’s bow

• Adding too much product without considering lip shape or proportion

What Should Happen Instead: Great lip enhancement should maintain the natural anatomy of the lips. The upper lip should be slightly smaller than the lower, with a well-defined Cupid’s bow. The corners of the mouth shouldn’t droop or protrude unnaturally.

In my practice, I use a conservative, detail-oriented approach to enhance lips while preserving softness and shape. Patients walk out with lips that are kissable, not comical.

Cheeks: The Foundation of the Midface

Common Mistake: Pillow Face or Chipmunk Cheeks

Full cheeks can be beautiful and youthful, but overfilling them or placing filler too medially (close to the nose) can create a puffy, unnatural look.

What Often Goes Wrong:

• Too much filler too high or too low

• Ignoring the natural cheekbone structure

• Using filler to “lift” when other techniques would be better (like threads or energy-based devices)

What Should Happen Instead: Cheek filler should restore youthful contour and midface support. The goal is to subtly lift and sculpt without exaggerating or distorting natural features. Placement should follow the natural high points of the cheekbones and should integrate smoothly with the surrounding facial anatomy.

My technique focuses on balance, structure, and integration with the rest of the face. This often requires a “less is more” mindset, combined with an artistic eye.

Jawline: Sculpting Without Sharpening Too Hard

Common Mistake: Hyper-defined Jaw or Boxy Jawline

Jawline contouring has exploded in popularity. A well-defined jaw can convey youth and strength, but too much filler can lead to a masculine, blocky, or overly squared appearance.

What Often Goes Wrong:

• Overuse of high-density fillers

• Ignoring gender-specific aesthetics (a female jawline is different from a male one!)

• Poor blending with chin and neck

What Should Happen Instead: Jawline filler should enhance natural contours, define the angle of the jaw, and smooth transitions between the chin, jowls, and neck. For women, the goal is usually elegant definition; for men, more structure may be desired.

As someone with both medical and sculptural training, I approach jawline enhancement with attention to angles, proportions, and harmony with the rest of the face.

Under Eyes: A Tricky but Transformative Area

Common Mistake: Tyndall Effect or Puffiness

Under-eye hollowing is a common concern, but it’s also one of the trickiest areas to treat with filler.

What Often Goes Wrong:

• Using the wrong type of filler (too hydrophilic)

• Injecting too superficially

• Overfilling, leading to puffiness or bluish tint (Tyndall effect)

What Should Happen Instead: The under-eye area requires finesse. Small amounts of a smooth, low-viscosity filler should be placed deeply and precisely. Often, this area benefits from a holistic approach, including treating the cheeks to support the tear trough.

In my hands, tear trough treatments are subtle, conservative, and tailored. I often use cannula technique to minimize trauma and ensure a smooth, natural result.

Temples: The Forgotten Volume Zone

Common Mistake: Hollowing or Overfilling

Temples lose volume with age, making the face appear gaunt or skeletal. But overcorrecting this area can result in bulging or distortion.

What Often Goes Wrong:

• Too much filler too superficially

• Poor choice of product

What Should Happen Instead: Temple filler should be placed deeply and gradually. The goal is subtle restoration of volume to create a smooth transition between the forehead and cheek.

This is often one of those “you don’t know it was missing until it’s fixed” areas—and when done well, the entire face looks more youthful.

---

Chin: Projection with Precision

Common Mistake: Witchy or Pointy Chins

Chin filler can do wonders for facial balance, especially in profile. But too much, or poorly placed product, can elongate or distort the lower face.

What Often Goes Wrong:

• Overcorrection in the vertical dimension

• Failure to blend with surrounding areas

What Should Happen Instead: Chin enhancement should aim to improve projection and balance, not dominance. The ideal chin varies by gender, ethnicity, and overall facial shape.

As with all filler areas, precise technique, product choice, and aesthetic judgment are key.

The Bigger Picture: Filler Isn’t Just About Fixing

One major mistake in aesthetic injecting is the “patchwork” approach: treating isolated areas without considering how they relate to the rest of the face. This can lead to an imbalanced or artificial look.

Facial aesthetics should be approached holistically. Every face is unique, and treatments should enhance the whole appearance, not just parts in isolation.

The Role of an Experienced Injector

At my practice, I take pride in crafting personalized treatment plans that are rooted in both science and art. I’ve spent two decades refining my eye, studying anatomy, and understanding how the face ages. I don’t chase trends or overfill. My goal is always to help patients look like the best version of themselves.

I also see quite a few patients who come in wanting to correct or dissolve filler from previous treatments. The good news? With the right techniques and an expert touch, many of these issues can be improved.

So, Why Do People Still Make These Mistakes?

Unfortunately, facial fillers have become widely available, and not all injectors have the same training, experience, or aesthetic sensibility. It’s not just about knowing how to inject—it’s about knowing why, where, and how much.

Experience matters. Anatomy matters. And so does artistry.

Final Thoughts: Your Face Deserves Expert Care

If you’re considering facial fillers—whether you’re a first-timer or looking for a refresh—choose your provider wisely. A skilled, experienced injector will:

• Take time to understand your goals

• Assess your entire face, not just one feature

• Use conservative, precise techniques

• Choose the right products for the right areas

• Prioritize natural, elegant results

In the right hands, fillers can be life-enhancing. They can restore confidence, enhance beauty, and help you feel your best.
