The price of forehead Botox depends on several factors, including the severity of the wrinkles, the type of botulinum toxin used, the doctor’s expertise, and the facility where the treatment is performed.
Before treatment, the doctor will determine whether the patient has:
Dynamic wrinkles may respond to a relatively small dose because the treatment mainly reduces excessive muscle contraction.
Deep, long-standing static wrinkles may require a different treatment plan. In some cases, botulinum toxin may be combined with filler or another skin-rejuvenation treatment.
The severity and type of forehead wrinkles affect the required dose and treatment cost.
Filler should not automatically be injected into every deep forehead line because the forehead is a vascularly sensitive treatment area. Combination treatment must be carefully assessed by a qualified medical practitioner.
Botox by Allergan is widely used and may be priced higher because of its brand reputation, clinical use, and manufacturing standards.
Korean botulinum toxin products, such as Botulax, are often more affordable and may provide an effect lasting approximately four to six months in suitable patients.
The doctor should recommend an appropriate product based on:
Patients should verify the exact product name, manufacturer, batch number, expiration date, and regulatory status before treatment.
An experienced doctor can assess the appropriate dose and injection points needed to soften forehead wrinkles while preserving natural facial expression.
Correct treatment planning can also reduce the risk of:
A reputable facility should have:
Professional facilities may charge more because the price includes medical assessment, authentic products, treatment planning, and follow-up care.
Botulinum toxin injections are relatively quick and generally require little recovery time.
No medical facility should guarantee a completely risk-free result. The treatment outcome depends on the product, dose, technique, anatomy, and individual response.
Forehead Botox commonly lasts approximately three to six months, depending on the product used, the dose, muscle activity, metabolism, and post-treatment care.
For some first-time patients, the effect may last approximately two to four months. With subsequent treatment, the effect may appear to last longer in some individuals because the treated muscles become less active over time.
However, this does not occur in every patient.
Because botulinum toxin is temporary, repeat treatment may be required to maintain wrinkle reduction.
Using an authentic botulinum toxin product may support safer and more predictable results.
The timing of maintenance treatment depends on how quickly muscle movement returns.
The doctor should reassess:
Botulinum toxin should not be repeated too frequently or administered before the effects of the previous treatment have been properly assessed.
Appropriate treatment timing may reduce repeated muscle folding and help prevent dynamic lines from becoming more deeply established. However, botulinum toxin cannot permanently stop skin ageing.

Kangnam’s botulinum toxin services provide several conveniences for overseas Vietnamese patients, including traceable products, individualised injection techniques, relatively rapid results, and online consultation before travelling.
Kangnam’s dermatology team assesses different facial structures and muscle patterns to determine:
Correct technique may reduce the risk of facial stiffness, loss of expression, brow asymmetry, and eyelid drooping.
Experienced doctors assess muscle movement and determine suitable injection points.
The risk cannot be eliminated completely, even when treatment is performed correctly.
The effects of botulinum toxin commonly begin to appear within approximately three to seven days.
The full result may take around 10–14 days to develop.
This treatment may be convenient for overseas Vietnamese patients with a short stay in Vietnam. However, patients should ideally allow enough time for the result to develop and for follow-up assessment before travelling.
Patients may submit photographs or join a video consultation before travelling.
The doctor may provide a preliminary assessment of:
This may reduce waiting time after arrival.
However, an online consultation cannot determine the exact dose or replace an in-person medical examination.
Kangnam follows a structured injection process using suitable needles and an individualised dose based on each patient’s condition.
The procedure is supervised or performed by a qualified medical practitioner and is designed to produce a natural-looking result while reducing swelling, bruising, and other avoidable risks.
The treatment follows a medically standardised procedure using traceable products.
One of the main risks of unusually cheap botulinum toxin treatment is the possibility of receiving an untraceable, improperly stored, counterfeit, expired, or excessively diluted product.
This may result in:
Repeated exposure to unsuitable doses or certain formulations may contribute to antibody formation and reduced treatment response in some patients. However, apparent treatment failure may also be caused by inadequate dosage, incorrect injection placement, poor storage, or an unsuitable product.
Botulinum toxin should only be administered by a qualified medical practitioner using an authentic and correctly stored product.
Kangnam states that it uses traceable botulinum toxin products.
At Kangnam, each patient undergoes an assessment before receiving an individualised treatment plan.
Patients should ask to verify:
Overseas Vietnamese patients may submit photographs before returning to Vietnam so that the doctor can provide a preliminary assessment of their forehead wrinkles.
The exact dose and treatment plan must still be confirmed during an in-person consultation.
