6 Myths About Fillers and Botox: A Doctor Explains
Fillers and Botox are widely used procedures, but they are also surrounded by many myths and misunderstandings. This article explains the medical facts to help you make informed and safe decisions. All information is based on medical principles and physicians’ clinical experience. At Mediqueen Clinic, we emphasize accurate education to support appropriate, natural-looking care outcomes. Results vary by individual.
Key points
- Fillers and Botox work differently: Botox (botulinum toxin) relaxes muscles to reduce expression-related wrinkles, while fillers restore lost volume. They cannot replace each other.
- A “frozen face” after Botox can be avoided: This outcome may result from an unsuitable dose or injection technique. Care by an experienced physician can help create a treatment plan that preserves a natural appearance.
- Fillers do not make the skin “sag” after they dissolve: Hyaluronic acid (HA) fillers gradually break down naturally and may also help stimulate collagen beneath the skin. An appropriate amount injected in the correct location does not make the skin looser than before.
- Stopping injections does not make you look worse: Once the effects wear off, the skin gradually returns to its previous condition while natural aging continues. It does not accelerate the development of wrinkles.
- Safety depends on three main factors: products that meet standards and are approved by the Thai Food and Drug Administration, a clean and hygienic clinic, and a physician with appropriate expertise and experience.
Myth 1: Botox and fillers are the same and can be used interchangeably
This is a very common misconception. Although both are used to address wrinkles, their mechanisms of action and indications are entirely different. Botox, or botulinum toxin type A, is a protein-based neurotoxin that inhibits the release of neurotransmitters that signal muscles to contract. This temporarily relaxes the injected muscles, making it suitable for dynamic wrinkles caused by repeated muscle movement, such as forehead lines, frown lines, and crow’s feet.
In contrast, fillers—particularly hyaluronic acid (HA), a substance naturally present in the body—restore volume lost with age. They are used for deep folds or laxity associated with static wrinkles, such as nasolabial folds and marionette lines, and for facial contouring, such as filling hollow temples or the mid-cheek area and enhancing the chin and lips. The choice of procedure therefore depends on a physician’s assessment. In some cases, both may be used together for broader treatment, but they cannot replace each other.
Myth 2: Botox makes the face stiff, tight, and unnatural
A “frozen” or “expressionless” face is not an inherent property of Botox. It can result from an injection technique or dose that is unsuitable for the patient’s individual anatomy. Before treatment, an experienced physician evaluates facial muscle activity carefully to determine precise injection points and dosage. The aim is to relax overactive muscles to an appropriate degree so that wrinkles soften while natural facial expressions remain possible.
At Mediqueen Clinic Pattaya, under the care of physician license no. 37670, treatment is personalized according to each patient’s needs and facial structure. Current techniques such as Microbotox or Mesobotox use smaller doses injected into more superficial skin layers to help smooth the skin and reduce the appearance of pores without affecting expression in the larger facial muscles. It is therefore important to communicate your preferences to the physician.
Myth 3: Long-term filler injections make the face and skin sag
This concern often arises from past cases involving substandard injectable substances. Hyaluronic acid (HA) fillers currently approved by the Thai FDA are biocompatible and gradually break down through the body’s metabolic processes over approximately 6–24 months, depending on the product and injection area. When an appropriate amount is injected into the correct location by an experienced physician, filler replaces volume lost from age-related fat or bone atrophy; it does not permanently stretch the skin.
Several studies also indicate that HA filler injections may mildly stimulate fibroblasts to produce new collagen and elastin in the treated area, which may benefit skin quality over time. Skin laxity noticed after filler breaks down is often associated with excessive injection volume, or overfilling, or with a product that was unsuitable for the relevant tissue layer. These factors depend on the treating physician’s clinical decisions, so choosing an experienced physician is important in reducing this risk.
Myth 4: Stopping injections makes the face more wrinkled than before
This belief is not supported by medical principles. When the effects of Botox or filler wear off, the skin and muscles gradually return toward their pretreatment condition while the normal aging process continues. The treatment does not accelerate deterioration. Feeling that one “looks worse” is often a psychological effect: after becoming accustomed to a smoother, more youthful-looking face while the treatment is active, the return to the previous appearance makes the contrast more noticeable.
Conversely, regular long-term Botox treatment may help delay the formation of fixed wrinkles by reducing repeated muscle contractions that can create deeply etched lines. Similarly, fillers temporarily support skin structure. Stopping injections simply allows natural processes to continue from where they would otherwise be; it does not create a delayed negative effect.
Myth 5: All filler and Botox brands are the same, so price should come first
Each brand and product line is developed with different technologies and properties for particular areas and concerns. For example, an under-eye filler should be soft and fine-textured and should not form visible lumps, while a filler used for chin enhancement or cheek lifting requires greater structural stability and lifting capacity. Botox products may likewise differ in molecular purity, diffusion, and associated proteins, which can affect outcomes, the likelihood of treatment resistance, and duration of action.
Choosing a product solely by price may increase exposure to counterfeit, illegally imported, or substandard products, which can cause serious adverse effects such as infection, inflammation, fibrosis, or allergic reactions. At Mediqueen Clinic, we use only products approved by the Food and Drug Administration, and patients may inspect the packaging and production lot number. Treatment costs include not only the product but also the physician’s expertise—license no. 37670—the clinic’s cleanliness and safety standards, and follow-up care. These factors deserve greater consideration than price alone.
Myth 6: Injections are simple procedures that anyone can perform; a physician is unnecessary
This is a particularly dangerous misconception. Filler and Botox injections are medical procedures and must be performed by a licensed physician. Facial anatomy is complex, with blood vessels, nerves, and multiple muscle and tissue layers. Injection into the wrong location or tissue plane can lead to serious complications.
For fillers, a major concern is accidental injection into a blood vessel, causing vascular occlusion. This may interrupt the blood supply and lead to tissue necrosis; if a vessel supplying the eye is affected, blindness may occur. Incorrect Botox placement can cause eyelid drooping, facial asymmetry around the mouth, or difficulty swallowing. An experienced physician has detailed anatomical knowledge and understands risk-reduction techniques, such as using a blunt-tipped cannula in certain areas. Receiving treatment from a physician in a properly regulated healthcare facility is therefore important for safety.
FAQ
Will jaw-reduction Botox make chewing difficult?
During the first 1–2 weeks after injection, you may notice some fatigue or tightness in the jaw when chewing hard or sticky foods because the targeted masseter muscle becomes less active and gradually decreases in size. In general, this does not significantly affect daily life because other muscles also assist with chewing. These symptoms usually improve gradually and resolve on their own.
Can under-eye filler form lumps or cause unnatural swelling?
The likelihood of lumps or swelling after under-eye filler depends mainly on three factors: 1) selecting an appropriate soft, small-particle filler; 2) the physician’s technique and experience in placing an appropriate amount in the correct tissue layer; and 3) the patient’s individual biological response. Care by an experienced physician can substantially reduce these risks. If a lump is caused by HA filler, an enzyme can be used to dissolve it.
Can filler be corrected if I am dissatisfied with the outcome?
Hyaluronic acid (HA) filler, a widely used type with an established safety profile, can be adjusted by injecting the enzyme hyaluronidase to dissolve unwanted or excess filler. This reversibility is an important safety feature. It is another reason to receive treatment from a physician at a properly regulated clinic where this enzyme is readily available.
Does aftercare require extra precautions in Pattaya’s hot, humid climate?
General aftercare principles are similar: initially avoid high heat, strenuous exercise, and alcohol. In Pattaya’s hot and sunny conditions, particular attention should be given to regular use of a high-SPF sunscreen to help prevent inflammation and support the duration of filler effects. Prolonged outdoor sun exposure and water activities should also be avoided during the first 1–2 weeks to reduce infection risk.
