Are Fillers Bad? An Honest Answer from a Sisu Injector

It's the question I'm asked more than any other in consultation right now, often before the patient has even sat down: "Are fillers bad?"

It's a fair question. And it deserves an honest answer.

The short version is this. Filler isn't bad. Bad filler is bad. And the conversation the industry, the media and patients are all having right now is, in a way, long overdue. Used well, by an experienced injector, in carefully chosen amounts, fillers can do beautiful, subtle work. Used badly, they can do real damage to a face. The reason the question is everywhere is because we've all spent the last decade looking at the second category.

Let me explain.

Why "are fillers bad?" is the question of the moment

One thing I've noticed more recently is that patients are focusing far more on achieving natural-looking results. Many people come to the clinic worried about looking "overdone" or unnatural, especially when it comes to filler. Searches for terms like "pillow face," "overfilled face," "filler fatigue" and "dissolving filler" have all surged. Social media is full of dissolving-filler before-and-afters and celebrity speculation about who has had what taken out.

What this tells me is not that filler is on its way out. It's that the public conversation has finally caught up with what good injectors have been quietly saying for years: more is not better, and obvious is not the goal.
The biggest misconception I correct in consultation is the idea that filler always has to look obvious. It doesn't. In fact, when filler is done properly, you simply look refreshed and like yourself, not "filled."

What "pillow face" and "overfilled" actually mean

When patients use words like "pillow face" or "overfilled," they're usually describing a very specific look: cheeks that look heavy or rounded, lips that have lost their natural shape, a face that has lost the small hollows and shadows that make a face read as healthy and dimensional.

This look isn't an inevitable consequence of filler. It's a consequence of too much filler, placed without enough thought for the face as a whole, repeated over time without reassessing.
The fix, and the reason there's so much filler-reversal content online right now, is dissolving. Hyaluronic acid fillers can be dissolved using hyaluronidase, and many patients are choosing to do this and start again with a more subtle, considered plan. That's a good thing, and a sign of a maturing industry.

The bigger point is that "overfilled" is a treatment outcome, not an inherent feature of filler. Good injectors don't produce overfilled faces.

The 1ml blueberry

The single most useful piece of information I share in consultation is something most patients are surprised by.

I often explain to patients that 1ml of filler, which sounds like a lot to many people, is actually only about the size of a blueberry. When placed strategically, small amounts can softly restore volume loss, improve facial balance and create a fresher appearance without dramatically changing someone's features.

Once you have that visual in your head, the whole conversation changes. A blueberry is not enough filler to transform a face. It is enough to soften a tear trough, refine a cheekbone, or hydrate a lip just a fraction. That's the gap between what patients fear filler will do and what filler actually does when it's done well.

Where filler genuinely helps (and where it doesn't)

It's worth being specific about the areas where well-placed dermal filler can make a real, subtle difference, and where it isn't the right answer.

Tear trough / under-eye filler. One of the most rewarding treatments to do well, and one of the most damaging done badly. A small amount of filler placed in the under-eye area can reduce dark circles, hollowness and the "tired all the time" look. It needs an experienced injector and careful patient selection. From €550 at Sisu Clinic Ireland.

Cheek and midface filler. As we age, the support in the cheekbone area gradually deflates. A conservative amount of filler here can restore facial balance and lift the lower face indirectly. The mistake patients see online is too much filler placed too high or too far forward. Done well, no one can tell. From €300.

Lip filler. The most discussed and most overdone area in aesthetics. Done well, lip filler is about definition, hydration and shape, not size. Many of the best lip treatments use 0.5ml or less. From €300.

Jawline filler / jaw sculpting. Increasingly popular for both men and women. A defined jaw can dramatically improve facial harmony, especially as the lower face softens with age. From €550.

Non-surgical rhinoplasty. A small amount of filler can soften a bump on the bridge or refine the nose tip. Highly technical, requires a skilled injector. From €400.

Where filler is not the answer. Skin laxity. Loose skin needs tightening, not filling. Dull or dehydrated skin needs skin quality treatments like Profhilo, polynucleotides or Sculptra, not filler. Significant volume loss across the whole face may need a regenerative approach (Sculptra) rather than ongoing filler.

So, should you get filler?

The honest answer is: it depends entirely on you, your face, and the injector you choose.

If you want subtle improvement, addressed to a specific concern, by an experienced doctor or nurse-injector, with restraint as the guiding principle, then filler can be a beautiful treatment. If what you're actually looking for is skin quality, glow or significant rejuvenation, you may be better served by a regenerative plan.

The single most important factor in the answer to "are fillers bad?" is who's holding the needle.

The Sisu approach

At Sisu, the way we approach filler is in line with the philosophy across all our Irish, UK and US clinics: results should look like rest, not work. That means small amounts placed strategically, a full-face assessment rather than chasing isolated areas, natural movement and expression protected, and a treatment plan that can be built on or stepped back from over time.

My goal is always for patients to still look completely like themselves, just more refreshed and confident.
