Filler refers to Hyaluronic Acid (HA), a large sugar molecule (polysaccharide) naturally found in the body — in the skin and joints. It plays a key role in retaining moisture and binding collagen, keeping the skin hydrated, plump, and elastic.
As we age, the body produces less HA and collagen. This leads to dryness, thinning skin, fine lines, and sagging. Filler injections help restore lost volume and smooth out these visible signs of aging.
The filler used in aesthetic medicine is a synthetic, biodegradable form of HA that has been approved by the Food and Drug Administration (FDA) as safe for the body. It comes in a gel-like consistency, and once injected into the skin, it fills in volume, smooths the skin's surface, and helps restore a more youthful appearance to the face.
Aside from filling deep lines, fillers can reshape the face, restore volume, and target specific concerns in many areas — under the eyes, temples, cheeks, smile lines, lips, jawline, and chin. The doctor will select the right injection points and techniques based on each person’s facial structure to achieve the best results.
Dark under-eye circles and deep tear trough lines are among the main reasons a face can look tired and worn out. Filler injected in this area helps fill in the tear trough, reducing shadows and dullness while adding hydration — leaving the under-eye area looking brighter and more refreshed immediately.

This technique adds volume along the lower lash line to create a soft, smiling look, similar to the natural fullness that appears when we smile. Unlike under eye fillers for dark circles, this focuses on enhancing charm and sweetness.

Sunken temples can make the face look uneven or too angular. Temple fillers restore balance, smooth out the facial contour, and give a softer, more harmonious look.

Hollow cheeks can make the face appear harsh or unbalanced. Fillers add volume back, creating a softer, healthier look and improving overall facial symmetry.

Cheek filler, also known as apple cheek filler, helps address flat or sunken cheeks, giving the face a fresher, more lifted appearance. Adding volume to this area creates fullness in the mid-cheek, while also softening the appearance of cheek lines. It is one of the most effective areas for achieving a noticeably younger-looking face. Full, well-proportioned cheeks are also widely regarded as a feature associated with favorable facial harmony.

With age, smile lines (nasolabial folds) remain visible even when not smiling, giving a tired or stern look. Fillers lift and smooth these lines, making the face appear softer and younger.

Lip filler helps enhance lip shape and definition, addressing concerns such as flat lips, downturned corners, or dryness with visible lines. It can add volume according to the desired style, whether it’s a Cupid’s bow shape or a Korean-style lip enhancement

Lines under the corners of the mouth often make the face look older. Fillers smooth these lines, brighten the expression, and bring back a more youthful look.

For those with a flat or undefined jawline, fillers sharpen the jaw contour, enhance dimension, and create a sleek, structured facial frame.

The amount of filler (CCs) depends on each person’s facial structure, skin condition, and the desired result. The doctor will assess carefully to recommend just the right amount, enough to see results, but not excessive.
Example of common filler amounts by area (approximate):
Injecting fillers in several areas during one session can bring a more noticeable transformation, since facial features are connected. For example, treating under eyes, mid-cheeks, and smile lines together gives a more harmonious and balanced result.
Fillers can be done all at once or in stages over time, depending on your preference and convenience.
After injections, fillers gradually settle and results become clear within about 1 month. On average, results last 8–12 months, since hyaluronic acid (HA) fillers naturally break down in the body.
Duration may vary depending on:
Both types use hyaluronic acid (HA), but their textures and purposes are different.
Filler for Face Contouring are designed to add volume, correct asymmetry, and smooth deep lines. They enhance facial proportions, giving a more youthful, balanced, and refreshed look.
Filler for Skin Quality (also called skin boosters) are lighter in texture. They focus on hydration, skin quality, and reducing fine lines. Instead of reshaping the face, they make the skin smoother, plumper, and healthier-looking.
Recommended skin fillers you’ll love
When selecting a filler product, quality, safety, and sourcing should always be considered. There are currently several high-quality authentic products available that meet international standards and have been approved by Thailand's FDA. Each formulation has specific properties suited to different injection sites.
A popular Korean filler trusted worldwide. Known for its versatility across different facial areas, Neuramis is praised for its reliable quality and affordable price.
A premium filler from Sweden, recognized for its advanced production technology and multiple product options for different skin concerns. Widely trusted by doctors globally.
A high-quality filler from the US, produced with unique Hylacross and VYCROSS technologies. These allow excellent hydration and natural-looking results.
Before getting fillers, the most important step is to make sure the filler is authentic and officially imported. No matter which brand or type you choose, it must be approved by the Thai FDA and distributed by an authorized company.
Easy ways to check if a filler is genuine:
If the clinic avoids showing these details or refuses to unbox the filler before use, consider it a red flag.
Although fillers are very popular and widely available, some clinics still use fake or unapproved products without informing customers, which can cause both short- and long-term risks.
Types of fake fillers to avoid:
Is Authentic Filler Safe? Authentic Hyaluronic Acid filler meets established safety standards, is fully biodegradable, and can be dissolved immediately if any issues arise. However, the procedure must be performed by an experienced physician — it should never be administered by unlicensed individuals or unverified practitioners.
Fat grafting uses your own fat, usually taken from the stomach or thighs, to restore volume in the face. While it’s natural, the results are unpredictable because some fat may dissolve or be reabsorbed by the body. This often requires multiple sessions, and if the fat spreads unevenly, it may cause lumps or uneven texture.
Program Fillers, on the other hand, offer more precision in both amount and placement. Results are immediate, there’s no downtime, and if you’re not satisfied, they can be adjusted or dissolved. For those seeking accuracy, safety, and predictable results, fillers are often the more convenient choice.
To achieve natural-looking results and minimize side effects, proper preparation before fillers and aftercare are very important.
Although filler injections are not complicated, preparation helps reduce needle marks and bruising that may last longer. Recommended:
Note: Pregnant or breastfeeding women should not get fillers for safety reasons.
How to take care of yourself after filler injections
Aftercare plays a big role in how well fillers settle and how long they last. Recommended:
No food restrictions, but to reduce swelling and bruising, avoid pickled foods, very spicy dishes, or high-sodium meals for 3–7 days.
Mild swelling may occur for 7–14 days, but it’s usually unnoticeable to others. Fillers will naturally blend into the skin within 4 weeks.
1. Consultation: Discuss concerns with the doctor, who will analyze your face and recommend the most suitable filler brand and type.
2. Preparation: Skin is cleansed and sterilized before treatment.
3. Filler check: The assistant opens the filler box in front of you and explains how to confirm it’s genuine.
4. Injection: The doctor performs the procedure according to plan. It usually takes 20–30 minutes.
5. Aftercare advice: Check results in the mirror and receive detailed aftercare instructions from the doctor.
6. Follow-up: Return after 1 month when fillers have fully settled for a check-up with no extra charge.
Not as much as you might think. Cold compresses are used, and most fillers (e.g., Neuramis) contain lidocaine. Extra numbing cream is available if needed. In sensitive areas like under eyes or midface, blunt cannulas may be used.
Summary: Fillers are a safe, non-surgical option to correct imperfections, contour the face, and slow aging. Results are immediate, downtime is minimal, and safety is high when using FDA-approved products with an experienced doctor. Choosing a trusted clinic ensures confidence and satisfying results.
At MEGA CLINIC, safety is our top priority.
As we age, the skin starts to sag, fat and collagen decrease, and facial bones shrink. This causes hollow areas and deep lines. Fillers work by restoring lost volume in these areas, balancing the face, and bringing back a youthful look that resembles your natural features before aging.
Injecting fillers in several areas during one session is possible and often recommended for a more balanced look. Common combined areas include the temples, cheeks, jawline, and chin. The doctor will decide how much filler to use and the right technique for each spot.
A blunt cannula is a soft, rounded-tip needle with a side opening that allows the filler to flow out. Its advantage is lowering the risk of hitting blood vessels, reducing bruising and swelling, and making the procedure safer.
Doctors usually use blunt cannulas in delicate areas with important blood vessels or thin tissues, such as under the eyes, Dolly Eyes, smile lines (nasolabial folds), and midface.
Lack of results can happen if the doctor is inexperienced or if the amount and placement of filler are not suitable for your face. In this case, the filler may not effectively correct the targeted area.
This is why choosing a skilled doctor and a trusted clinic is essential to achieve results that meet your expectations.
HA fillers are highly biocompatible and naturally break down in the body. When performed by an experienced doctor with genuine fillers, they are generally safe. “Often” can mean two things:
No, not necessarily. If the doctor sees that more can be added, you can get a top-up without waiting for the old filler to vanish completely. This is common in areas that move a lot, such as smile lines or lips.
Not at all. You can switch brands or types, as long as they are FDA-approved HA fillers. The doctor will recommend the right product for your skin needs and desired results.
The most important thing is to make sure the clinic uses authentic fillers and has experienced doctors to advise on the best choice.
Dissolution is carried out using an enzyme called Hyaluronidase, which breaks down Hyaluronic Acid quickly and safely, helping the skin return to its original state in a short time.
It is usually done when the result is unsatisfactory, such as lumps or unevenness. Although rare, it can happen, and this method provides a quick solution.
Note: Authentic HA filler can be dissolved completely — 100% — with no residue left in the body. This is in contrast to counterfeit substances such as liquid silicone, which cannot be dissolved and must instead be surgically removed or scraped out, carrying significantly higher risks.
Yes. You can live normally after treatment. Traveling or flying is fine. However, if you want a follow-up once the filler has fully settled, it’s best to see your doctor around one month later, especially if you plan to be away for a long time.
