Is Filler safe? Da Nang Doctor gives detailed answers is the top question for those considering this aesthetic medical procedure. Filler, also known as dermal filler, is a gel-like material injected under the skin to restore volume or contour features.

The majority of Filler used today (and 100% at Foxy M.D) is Hyaluronic Acid (HA) based Filler.
What is HA? HA is a natural substance present in the human body, concentrated in the skin, joints, and eyes.
High Biocompatibility: Due to its composition being similar to natural substances in the body, HA Filler has high biocompatibility. This allows the body to easily accept the Filler without a strong rejection reaction.
Resorbability: HA Filler has the ability to biodegrade and gradually dissolve over time (usually $6-18$ months, depending on the type). This means the Filler will not remain permanently in the body, reducing the risk of long-term complications.
Essentially, if genuine Filler is used and the technique is correct, Filler is a method considered safe and recognized by medicine. This safety stems from the commitment of the medically standardized doctor team.
When learning about is Filler safe, you need to clearly differentiate between two types of Filler:
Safe Filler (Genuine HA): Has clear origin, is licensed by the Ministry of Health, includes anti-counterfeit stamps, verifiable barcodes, and is biodegradable. This is the type of Filler used at Foxy M.D.
Dangerous Filler (Counterfeit/Unregulated Filler): Often liquid Silicone or permanent fillers of unknown origin. They lack the ability to self-resorb, easily cause severe complications (lumps, fibrosis, permanent deformation), or even necrosis.
The use of unregulated Filler is the main cause of complications, leading many people to worry about is Filler injection harmful.
Whether Filler injection is safe or not depends not only on the quality of the Filler but also heavily on the technique used. Safe Filler injection in Da Nang must ensure the following factors:
The Doctor is the key factor determining the safety and success of the injection.
Extensive Anatomical Knowledge: The facial area has many important blood vessels and nerves. The Doctor must have solid anatomical knowledge to avoid injecting into blood vessels, the main cause of vascular occlusion complications.
Precise Injection Technique: The Doctor needs to correctly identify the skin layer and injection location (epidermis, dermis, subcutaneous, or supraperiosteal) to ensure the Filler does not shift, clump, and achieves a natural aesthetic result.
Complication Management: In the event of an undesirable complication, only a specialized Doctor has sufficient knowledge and the dissolving agent (Hyaluronidase) to manage it quickly and timely. At Foxy M.D, the injection procedure is performed and supervised by a team of medically standardized doctors.
Filler Must Be Genuine: Foxy M.D commits to only using $100\%$ genuine Filler, with clear origin and licensed for circulation. This is a mandatory criterion to ensure is Filler safe.
Sterile Injection Procedure: All injection tools (needles, cannulas) must be single-use and absolutely sterile. The injection room environment must meet medical standards to prevent the risk of infection.
Not everyone is suitable for Filler injection. The Foxy M.D Doctor will thoroughly examine, assess skin condition and overall health, and listen to your wishes to create the most appropriate injection plan. This procedure helps optimize results and minimize risks.
When discussing Is Filler safe? Da Nang Doctor gives detailed answers, complications cannot be ignored. Complications often occur due to two main reasons: using counterfeit Filler or incorrect injection technique.
Minor Complications (Temporary): Swelling, redness, bruising, slight pain at the injection site. These are completely normal and common reactions, usually disappearing after 3-7 days. Proper cold compression helps reduce swelling and bruising.
Moderate Complications (Easily Managed): Lumps, Filler displacement. Often caused by injecting too superficially, using unsuitable Filler, or improper post-injection care. The Doctor can easily fix this through massage or injecting a Filler dissolving agent.
Severe Complications (Rare): Vascular occlusion, skin necrosis. This is the most dangerous complication, occurring when Filler is injected directly into a blood vessel, blocking blood flow to the tissue. This complication requires immediate emergency treatment by a specialized Doctor.
Is Filler injection harmful if repeated multiple times?
Safe if Genuine Filler and Correct Dosage: If you use genuine HA Filler, inject with the correct dosage and technique, repeating the injection (touch-up) after $6-18$ months is completely safe and recommended to maintain the results.
Risk when injecting too much: Injecting an excessive amount of Filler in a short time or injecting into the wrong layer can cause pressure on skin tissue, leading to skin stretching or even clumping. Therefore, consulting a Doctor to determine the appropriate dosage is crucial.
The biggest difference when having a Filler injection at Foxy M.D is the ability to manage complications:
Direct Specialized Doctor: Helps early recognition and quick management of vascular occlusion signs within the critical few minutes.
Availability of Dissolving Agent: Foxy M.D always has the dissolving agent (Hyaluronidase) available for immediate injection to dissolve the Filler in case of vascular occlusion.
Absolute Safety Commitment: Foxy M.D commits to clear results and absolute safety with a team of medically standardized doctors.
Is Filler safe often comes with questions about cost. The cost of Filler injection at Foxy M.D is commensurate with the safety, Filler quality, and Doctor's expertise you receive.
The cost for the Filler injection service at Foxy M.D will depend on various factors: Filler brand (premium or standard), injection area (nose, chin, cheeks, temples), and the quantity (cc) required.
I cannot publicly disclose a specific price, but the cost for one cc of genuine Filler, performed by a specialized Doctor at Foxy M.D, will be within a reasonable range, commensurate with the premium product quality and absolute safety committed by the clinic.
The following factors help you understand the differences in cost for safe Filler injection in Da Nang:
Filler Quality: Genuine, traceable Filler, certified by the FDA/Ministry of Health (e.g., premium lines) always has a higher price than unregulated or poor-quality Filler.
Doctor's Expertise: Services performed by a specialized Dermatology Doctor, with high experience and precise technique, will have a higher cost compared to non-specialists.
Injection Area and Dosage: Complex injection areas (like the nose, temples) or areas requiring a larger dosage of Filler (like filling hollow cheeks) will have a higher cost.
Warranty/Insurance Package: Some Filler service packages at reputable facilities may include a warranty or insurance, protecting your rights in case of complications.
My advice: Safety and optimal aesthetic results should be the top priority; do not choose an injection location based solely on cheap prices.
How can I identify genuine Filler?
Answer: Genuine Filler must have an anti-counterfeit stamp, verifiable barcode, be intact in its original box, and have clear proof of origin documentation from the authorized distributor. At Foxy M.D, you are always allowed to check the product before injection.
Is a reaction test required before Filler injection?
Answer: For modern HA Filler, a skin reaction test is almost unnecessary due to its very high biocompatibility. However, if you have a highly sensitive constitution or a severe allergy history, the Doctor may consider a test.
Does Filler injection hurt?
Answer: The pain sensation is very mild, comparable to an ant bite, because genuine Filler often contains Lidocaine (local anesthetic) inside. The Foxy M.D Doctor will also apply a numbing cream or perform a local block before injection to ensure maximum comfort.
How long does Filler typically last?
Answer: The longevity of HA Filler is usually $6-18$ months, depending on the type of Filler, the injection location (areas with more movement like lips dissolve faster), and individual metabolism. Proper post-injection care helps extend its durability.
What precautions are necessary to ensure the Filler is safe and long-lasting?
Answer: You need to avoid: strong physical impact on the injection area ($1-2$ weeks), high temperatures (saunas, hot baths, heaters) and alcohol ($1-2$ weeks). Additionally, you need to drink enough water for HA to work effectively.
What should I do if I don't like the Filler injection result?
Answer: If HA Filler is injected, the Doctor can inject a dissolving agent (Hyaluronidase) to dissolve the Filler almost immediately. This is a major advantage of HA Filler compared to other permanent fillers.
