What is Facial Filler?
What is facial filler, what does it correct and what does it not correct?
Facial filler is a non-surgical procedure that supports volume and contour reduced with age or structurally in the face by injecting a product under the skin. It is also known as dermal filler or aesthetic filler; commonly referred to simply as “filler.” A dental filling is a separate procedure used in dentistry for treating cavities and is unrelated to facial filler. When volume decreases in the cheeks and temples the face looks tired and the folds at the corners of the mouth deepen; volume and contour in the lips and chin tip vary from person to person. Facial filler supports these areas while respecting facial proportions.
Knowing what facial filler does not correct is also important to set realistic expectations. Significant sagging and excess skin are related to tissue position rather than volume; lines caused by animation stem from muscle movement; pigmentation and skin texture concern the surface. For these complaints facelift, botox or fractional laser are considered separately. Adding excessive volume does not lift sagging; on the contrary, it can make the face appear heavy.
What does filler do in each area and where is caution required?
The type and amount of filler are chosen not by package name but according to where and how much volume is lost. Hyaluronic acid fillers are produced in varying densities: softer products are preferred for delicate areas like the lips and under the eyes, while denser products are chosen for support areas such as the cheeks and chin. Duration of effect also varies by area; products are absorbed faster in areas with more movement. The table below summarizes the general relationships; the personal plan is determined at the examination.
| Area and finding | Commonly considered approach | Tendency for duration of effect | Note |
|---|---|---|---|
| Lips: thin lips, unclear border, asymmetry | Soft hyaluronic acid lip filler | Tends toward the shorter end of the 6–12 month range due to movement | Swelling is more pronounced in the early days |
| Cheeks and cheekbones: midface volume loss | Denser hyaluronic acid filler | Generally tends toward the longer end of the range | Midface support also affects the nasolabial fold appearance |
| Chin tip and jawline | Dense hyaluronic acid filler | Generally tends toward the longer end of the range | Limited effect in prominent double chin and sagging |
| Under-eye: hollowing present, no bags | Cautious amounts of soft filler | Varies with product and skin characteristics | If there is bagging, consider eyelid surgery |
| Nasolabial and marionette lines | Often address cheek support first, add filler to the fold if needed | Varies with facial movement | Filling the line alone can make the face look heavy |
| Generalized thinning, decreased skin quality | Biostimulator product | Develops gradually, varies by product | Not dissolvable with enzyme |
| Significant sagging, neck laxity | Facelift or neck lift | Outside the scope of filler | Surgical evaluation required |
The nose, forehead and glabella require more caution for fillers due to vascular anatomy. Filler in the nose only camouflages small contour differences; it does not change the structure of the nose and does not replace rhinoplasty. If there is bagging or excess skin under the eyes, eyelid surgery may be a more appropriate option.
How much filler is needed, what does a milliliter mean?
The amount required for facial filler is expressed in milliliters (ml) and is determined individually according to the desired change, skin thickness and previous procedures. 1 ml is about one-fifth of a teaspoon; even such a small volume change can be noticeable on the face. Therefore, the milliliters used by someone else are not a ready-made measure for your face: the amount needed to define only the lip border differs from what is needed to support the cheeks, chin tip and jawline together. Products come in syringes of different volumes; not every syringe is 1 ml, so “syringe” and “milliliter” are not the same thing.
Rather than using excessive product in a single session, it is often more predictable to be conservative in the first application and add a small amount at the control visit after swelling has subsided if necessary. The procedure record should include the product name, batch number, amount and region; this record facilitates future procedures and, if necessary, decisions about dissolution.
Permanent fillers, previously placed fillers and fillers in men
Permanent fillers are the most difficult option to reverse in facial filler: if nodules or irregularities develop over time, their removal can be difficult or sometimes impossible. For this reason, hyaluronic acid fillers, which decrease over time and can be dissolved if needed, are a more predictable option. In patients who previously had fillers, the type, amount and date of the prior product alter the plan; adding new product over an unknown or permanent filler can increase problems. If you are unhappy with a previous hyaluronic acid filler, dissolving it first and then replanning if necessary is possible.
In men, facial filler often targets a more angular and defined contour in the chin, jawline and cheeks; the round cheek fullness commonly desired by women may be inappropriate for a male face. Because male facial skin is generally thicker, product selection and amounts are planned accordingly.
Can facial filler be combined with other procedures?
Facial filler can be planned alongside other procedures in suitable patients; the most commonly concomitant procedure is botox. While filler supports volume, botox softens dynamic lines. Surface procedures such as fractional laser can be added in a separate session; options like energy-based treatments and thread lifts for mild laxity are described on the Non-Surgical Face Lift page. If a facelift is to be performed, the patient’s own fat may be considered for volume support instead of filler. Discussing multiple procedures does not mean all are necessary; at the examination each recommendation and its intended target are explained.
How to compare facial filler offers?
When comparing facial filler offers, look at what the offer includes before comparing price per milliliter or per area. Some offers are given per milliliter, others per area or with a package name like “full face”; these offers cannot be compared unless the total amount and product name are specified. The same amount does not yield the same result with different products and in different areas. When requesting an offer, asking the following questions will help:
- Which product will be used, what is its name and type, can I see the box and the label?
- Which areas will be treated and what is the total ml to be applied; what is the syringe volume?
- Who will perform the procedure; what is the intervention plan in case of vascular occlusion?
- Is the 2-week control and potential small additional application included in the price?
- Will I be given the procedure record (product, batch number, amount, region)?
Facial fillers for aesthetic purposes are not covered by SGK. Procedures performed with products sold online or with needle-free filler pens pose serious risks because the product source and injection depth are unknown; the U.S. Food and Drug Administration (FDA) also warns against fillers sold directly to consumers and needle-free application pens.
If you are coming from out of town or abroad
Op. Dr. Hasan Büyükdoğan's clinic is located on Bağdat Caddesi in Kadıköy, on the Asian side of Istanbul. Facial filler does not require rest; however, it is recommended to stay in Istanbul for at least one night so you can easily contact the clinic in case of an early question or issue. Because the final appearance becomes clear at around 2 weeks, how the control will be performed is planned before the procedure. Photographs can be shared securely for preliminary assessment; however, photos do not replace an in-person examination and the definitive plan is made face to face. Turkish, English or German can be spoken during the consultation.
What the procedure can address
Not every patient receives the same treatment; the points below may be considered together or separately, depending on the person:
- 01Volume in the lips, definition of the lip border and side-to-side differences
- 02Decreased volume in the cheeks and cheekbone (midface)
- 03Profile at the chin tip and contour of the jawline
- 04Nasolabial and marionette lines from the mouth corners downward
- 05Hollowing under the eyes causing a tired appearance (in appropriate candidates)
- 06Temporal hollowing and balance of facial proportions
Who may be a candidate?
Who may be a candidate?
Facial filler is considered for adults whose complaint stems from volume loss or contour deficiency; it is generally not performed for aesthetic reasons under 18. The decision is based more on facial structure, where volume is lost and expectations than on age. Candidates who fully disclose previous fillers and facial procedures, the products used and their health status, who wish to preserve facial proportions and understand the result is temporary are more suitable.
Who may not be suitable?
- Active infection, inflamed acne or active cold sore in the treatment area
- Pregnancy or breastfeeding
- Known allergy to the product to be used or to the local anesthetic it contains
- A bleeding disorder that increases bleeding tendency (requires separate evaluation first)
- Unknown or permanent filler in the treatment area (requires separate evaluation first)
- Complaint primarily due to pronounced sagging or excess skin
Facial filler does not lift sagging tissue or remove excess skin. The aim is not to make the face resemble someone else’s but to support lost volume within the person’s own proportions.
The doctor's examination approach
The examination looks beyond appearance to the person's overall anatomy and expectations. Key points assessed:
- Where and how much is reduced
- Harmony with the whole face
- Skin thickness and elasticity
- Laxity that filler will not correct
- Right and left face differences
- Appearance while speaking and smiling
- Previous filler, product and date
- Desired and undesired changes
The process
In planning facial filler, the face is evaluated from the front, side and in motion; standard photographs are taken for comparison. Which areas will be treated, the product name and type, approximate amount, needle or cannula preference and the limits of the expected change are discussed clearly. Signs of serious risks such as vascular occlusion and how they would be managed are also explained before the procedure.
-
1
Examination
Facial proportions, volume loss, previous procedures and health information are evaluated.
-
2
Personal plan
Areas, product type, approximate amount and expected change are determined; risks are explained.
-
3
Preparation
The skin is cleaned and wiped with antiseptic; if necessary numbing cream is applied and areas are marked.
-
4
Procedure
Filler is placed with a needle or cannula in the planned areas; generally takes 15–30 minutes depending on the number of areas.
-
5
Post-procedure
Initial appearance and swelling are assessed, aftercare instructions and emergency signs are explained.
-
6
Control
Around 2 weeks later, when swelling has subsided, the result and symmetry are assessed; a small additional application is made if necessary.
Technique and medical approach
The method depends on the patient; no single technique suits everyone. Main points considered:
| Approach | Description |
|---|---|
| Hyaluronic acid filler | The most commonly used product type in facial filler. Products of different densities are chosen according to areas such as lips, cheeks or chin; can be dissolved with the enzyme hyaluronidase if needed. |
| Lip filler | Performed for lip volume, border definition and side-to-side differences. The goal is to keep the lip in proportion with the face; swelling in the lips may be more noticeable than in other areas and the effect may be shorter. |
| Cheek and midface filler | Supports reduced volume in the midface; cheek support also affects the appearance of the nasolabial fold. Excessive volume is kept in check because it can make the face look heavy and rounded. |
| Chin tip and jawline filler | By moving a receding chin forward it improves profile and by defining the jawline it supports lower face contour. A more angular line is targeted in men; it does not remove pronounced double chin or sagging. |
| Under-eye (undereye/tear trough) filler | For selected candidates with under-eye hollowing, applied with softer products and cautious amounts. Not suitable if there is bagging or excess skin; in that case eyelid surgery is considered. |
| Biostimulator fillers | Products containing calcium hydroxyapatite or poly-L-lactic acid; they stimulate collagen production in the tissue and show effect over time, and some require multiple sessions. They cannot be dissolved with an enzyme like hyaluronic acid. |
Preparing for the procedure
The points below are general information and do not replace personal medical instructions. Your own preparation is set at the examination.
Recovery
-
Day of procedure
First 24 hours
Mild swelling, redness and tenderness occur; cold compresses provide relief. No makeup and no alcohol for the first 24 hours; do not press the area, and only massage if the physician recommends it.
-
Day 1–2
First days
You can return to daily life the same day. Intense exercise, sauna and hammam should be postponed for 24–48 hours; sleeping with your head slightly elevated on the first night reduces swelling.
-
Day 3–7
First week
Swelling mostly decreases noticeably; lip swelling may last longer. If bruising occurs it usually resolves within 1–2 weeks.
-
Around day 14
Second week
The product settles into the tissue and the final appearance becomes clear. At the control visit the result and symmetry are assessed and a small addition is made if necessary.
-
6–12 months
Months
Hyaluronic acid filler is gradually absorbed by the body; the decision for repeat application is made at examination.
After facial filler you are more likely to feel tightness, tenderness and swelling rather than pain; these usually decrease within a few days. Severe or progressively increasing pain, skin whitening, gray-blue discoloration or changes in vision during or after the procedure require urgent evaluation: contact the team and emergency health services immediately without waiting for the control date or message response.
Results and realistic expectations
The effect of facial filler is visible immediately after the procedure, but the final appearance becomes clear as swelling subsides over about 2 weeks. The effect of hyaluronic acid fillers usually lasts 6–12 months; the duration varies with product density, treated area and individual factors: shorter in highly mobile areas like the lips, longer in less mobile areas like the cheeks and chin tip. Changes with biostimulator fillers develop gradually. Facial filler does not stop sagging; as aging continues the needs change over time.
Risks and limitations
Risks of facial filler are explained before the procedure according to the patient’s health status, the area and the product. The most common are swelling, bruising and tenderness. The rare but most serious risk is injection into or compression of a vessel by the filler; this can cause tissue loss and very rarely vision loss. Therefore a physician who knows the anatomy, an appropriate technique for the area and a plan for rapid intervention are important.
- Swelling, bruising, redness and tenderness
- Asymmetry, irregularity or small palpable firmness
- Product migration or an overfilled appearance
- Bluish discoloration through thin under-eye skin or prolonged swelling
- Cold sore flare-up (especially with lip filler)
- Infection, allergic reaction or late-onset nodules
- Tissue loss due to vascular occlusion and very rarely vision loss
Alternative and complementary options
In some cases other methods may be considered. Each has its own limits and is not right for everyone:
| Method | Description |
|---|---|
| 1Botox | Softens dynamic lines by reducing muscle movement; does not add volume. |
| 2Fat grafting | Provides volume support using the patient’s own fat; it is a surgical procedure because fat must be harvested and the amount of fat that survives varies by patient. |
| 3Non-surgical face lifting methods | Energy-based treatments or thread lifts can be considered for mild laxity and skin quality; they do not add volume. |
| 4Facelift | A surgical procedure that repositions tissues in significant sagging; filler does not lift sagging. |
| 5Eyelid surgery | A surgical option considered instead of filler if there is bagging and excess skin under the eyes. |
