How is full-face filler different from single-area filler, and how long does it last?

Does full-face filler mean filling the entire face?

No. Full-face filler doesn't mean putting filler everywhere on the face. It means looking at the face as a whole, assessing all the hollow areas at once, and dividing the filler among only the spots that need it.

The areas usually considered are the forehead, temples, front cheeks, side cheeks, nasolabial folds and chin. In many cases we choose only two to four areas that are actually hollow, and leave areas that aren't sunken alone.

So the key to full-face filler is distribution, not volume. The same amount can change your impression very differently depending on whether it goes into one area or is spread in small amounts across several.

How is it different from single-area filler?

The biggest difference between single-area filler and full-face filler is the starting point. Single-area filler begins with the one spot the patient points to, such as the nasolabial folds, forehead or chin. Full-face filler first looks at facial proportions and how volume is distributed.

Volume loss with age doesn't happen in just one place. Facial fat is divided into several compartments that shrink at different rates, and the bone around the eyes and jaw is also gradually resorbed. These changes are linked: hollow temples make the cheekbones stand out, and loss below the front cheeks makes the nasolabial folds look deeper.

In a face like this, filling only the most noticeable spot can make the hollow right next to it stand out more, or make that one area look prominent and unnatural. Full-face filler accounts for these links and fills the areas behind the problem together. Instead of putting a large amount into the nasolabial folds alone, for example, we may support the front and side cheeks a little to reduce the depth of the folds.

On the other hand, if only one area is truly hollow, single-area filler is enough. Full-face filler is not always the better choice; we decide after seeing how widespread the hollowing is.

What is filler that supports the facial retaining structures (retaining ligaments)?

The skin, fat and SMAS of the face don't simply rest in place; they are held by dense fibrous tissue running from the bone and deep fascia toward the skin. These structures around the cheekbones, jaw and in front of the ear are commonly called retaining ligaments. As their support weakens with age, the tissue between them descends and borders such as the nasolabial folds and jawline deepen [1].

So-called retaining-ligament filler applies this anatomy to filler treatment. In Korea, Dr. Hong Gi-Woong's research group has described the concept through anatomical and ultrasound studies. Their explanation is that placing small amounts of highly cohesive filler beneath the SMAS around points where fibrous tissue attaches densely increases local tissue density and SMAS tension, and this force is transmitted to the skin through the retaining structures, so contours can be refined with a small volume [2][3].

Recent studies suggest these structures are not true ligaments connecting bone to bone like those in the limbs, but closer to a web-like fibrous anchoring network. They also emphasize that the location and strength of these structures differ in East Asian faces, so injection points need to be chosen more precisely for each area [4].

In faces where sagging has only just begun, Serene Clinic first supports these retaining points with small amounts before filling hollows, then fills only the remaining depressions. This can reduce the total volume needed for the same result and helps keep filler from becoming noticeable with facial expressions. However, the evidence for this approach is still mainly anatomical and ultrasound studies and clinical observation, and larger comparative studies are needed. It does not replace lifting in faces with clear sagging.

What are MD Codes, and how do we use them?

MD Codes™ is a filler planning system developed by Brazilian plastic surgeon Maurício de Maio. It divides the face into anatomical units and assigns each unit a code specifying injection depth, whether to use a needle or cannula, the injection technique, and the minimum volume needed to achieve a visible change [5].

Another feature of MD Codes is that it starts from the impression the face gives rather than from individual lines. It first identifies the impression the patient wants to change, such as looking tired, sad or angry, then selects and treats the units that contribute to it in order [5].

Rather than following MD Codes exactly, Serene Clinic uses it as a checklist so nothing in the plan is missed. After agreeing on the impression you want to change, we organize which areas to treat at what depth and volume, much like a code, and adjust volume and placement for the bone structure and retaining structures of East Asian faces. Points for supporting retaining structures and points for filling hollows are marked together on one plan, and we explain why each area is treated.

In what order is a custom design decided?

Design starts by looking at the face from the front, side and at an angle with a neutral expression. We check the profile line from forehead to nose tip to chin, hollows in the temples and side cheeks, the height of the midface and left-right differences, and we talk about the look you want.

Next we set priorities. We fill the hollow that most affects your overall impression first, then reduce or skip the amount in surrounding areas based on the result. At Serene Clinic, our principle is to take the amount that might have gone into one area, divide it across a whole-face plan, and inject small amounts only where needed.

Each area also suits a different product. For areas that receive force from expressions and chewing, such as the nasolabial folds and side cheeks, we mainly use Neuvia (a PEG-crosslinked hyaluronic acid filler), whose high cohesiveness means less spreading or shifting. Where deep support is largely lost, we consider Radiesse (CaHA). For areas like the forehead and temples, where a broad surface needs to blend smoothly, we choose a product based on how well it spreads.

When choosing a filler, we look less at how much volume it adds and more at how long and how steadily it holds the designed shape. In full-face filler, which covers several areas, this difference shows directly in the overall balance.

Which faces does it suit, and which does it not?

Full-face filler suits faces with hollowing in several areas at once. This includes faces that look gaunt and tired because the temples, front cheeks and side cheeks are all sunken; faces where one area stands out after earlier filler in that area alone; and people who want to refine their overall look but find surgery too much.

When sagging is the main cause, we don't start with full-face filler. Adding filler while the cheeks and jawline have dropped increases weight and can make the face look heavier and wider. In these cases we first reposition tissue with lifting such as Xerf or Ulthera, then fill only the remaining hollows.

We postpone treatment during pregnancy or breastfeeding, or if there is inflammation or skin infection where we would inject. If you have an autoimmune disease, take blood-thinning medication, or have had a sensitivity reaction to filler ingredients before, be sure to tell us at your consultation.

If you expect a dramatic change in face shape all at once, full-face filler isn't the right direction. It works by keeping the change in each area small so the whole face is refined naturally.

How long do the results last?

Hyaluronic acid filler shows volume right after injection and then breaks down gradually in the body. How long it lasts depends on the product's crosslinking and firmness, the amount and depth injected, how much the area moves and your metabolism, so it ranges widely from several months to over a year.

Even within one face, each area fades at a different rate. Areas that move a lot when talking and chewing, such as around the mouth and the nasolabial folds, often seem to fade sooner, while areas with less movement, such as the forehead and temples, tend to last longer. So after full-face filler, it's common to top up only the areas that faded faster rather than redo everything.

Filler is absorbed over time, so it isn't permanent. Rather than injecting a large amount from the start to make it last longer, starting with a moderate amount and adding when needed is better for keeping a natural look over time.

Is it done all at once or in stages?

If the total amount needed is small, we do it in one session. If many areas are hollow or the total amount is large, though, we suggest splitting it into two sessions.

Right after injection, swelling makes volume look larger than it really is. Looking again after 1–2 weeks, once the swelling has gone down, some areas turn out to need less than first expected, which helps avoid overcorrection. If lifting is also planned, it is more accurate to check the change in position after lifting before deciding the amount.

What is the procedure like, and what are the side effects?

For full-face filler we use both numbing cream and anesthetic injections to keep pain to a minimum. You can return to normal activities right away, and swelling and bruising at injection sites may last from a few days to about 2 weeks. On the day of treatment, avoid spicy and hot foods, alcohol, saunas and intense exercise, and for a few days don't press or rub the treated areas hard.

The side effect that needs the most attention is vascular complications. The forehead, glabella, area around the nose and nasolabial folds have blood vessels running through them, so a vessel can rarely become blocked. If after treatment your skin turns pale or dark red, pain keeps getting worse, or your vision becomes blurry, contact the clinic right away.

Other possible issues include left-right differences, palpable nodules and filler migrating to surrounding areas. Hyaluronic acid filler can be dissolved with an enzyme to correct it, but CaHA products such as Radiesse cannot be dissolved, so we are more conservative about where and how much we inject.

Prices (as of the October 2026 menu)

Full-face filler isn't a fixed package; the products and amounts needed for each area are added up. We'll give you details based on your plan after a consultation.
