What is Botulinum Toxin for Upper Lip and Perioral Lines?
The aim in botulinum toxin applications is to modulate target muscle or gland activity in a temporary and controlled manner. The result varies depending on individual anatomy, muscle strength, application area, and clinical goal.
Why are perioral lines a sensitive area?
The muscles around the mouth do not only produce facial expressions; they also participate in functions such as speaking, drinking, whistling, and lip closure. Therefore, a delicate balance is required between the aesthetic goal and the preservation of oral function.
Is every upper lip line muscle-derived?
No. Factors such as skin aging, sun damage, volume loss, and smoking can also contribute to lines. In deep lines noticeable at rest, reducing muscle activity alone may not be sufficient.
Who can it be considered for?
Because functions such as speaking, using a straw, whistling, and eating/drinking are associated with the orbicularis oris, a conservative approach is required due to the risk of functional side effects.
Pre-procedure evaluation
Our approach in our clinic is to evaluate the history, dynamic examination, facial or functional anatomy, asymmetry, previous procedures, and the individual’s goals together, rather than applying a standard point scheme. In the evaluation, the person’s medical history, anatomical characteristics, previous applications, and treatment expectations are addressed together.
Scientific evidence
This application area is evaluated based on botulinum toxin’s effect of temporarily reducing muscle activity. Scientific publications and expert consensuses indicate that patient selection and anatomical evaluation are important for outcomes and safety.
When does the effect begin and how long does it last?
The effect usually begins to appear within the first few days and becomes more pronounced in the following days. The duration may vary according to the application area, muscle activity, and individual biological differences. The timing of the follow-up examination is planned according to the type of application.
Possible side effects
Pain, tenderness, bruising, or headache may occur at the injection site. Specific to the region, effects such as temporary asymmetry, unintended weakness in adjacent muscles, changes in eyelid/eyebrow position, changes in oral functions, or difficulty swallowing may occur. Rare but serious generalized muscle weakness, or difficulty swallowing or breathing, requires emergency medical evaluation.
Who may it not be suitable for?
Active infection in the application area, known hypersensitivity to botulinum toxin ingredients, and certain neuromuscular diseases require special caution. Pregnancy/breastfeeding, anticoagulant use, aminoglycosides or medications that can affect neuromuscular transmission, and previous botulinum toxin applications should be shared with the physician.
Things to consider after the procedure
It is advisable not to unnecessarily rub or intensely manipulate the application area on the same day. Short-term redness, tenderness, or small bruises may be observed at the injection points. It is often possible to return to daily life in a short time; if heavy exercise, intense heat exposure, or another facial procedure is planned, follow your physician’s recommendation according to your individual situation. Because the effect is not immediately complete, an early judgment about symmetry should not be made in the first hours or first days. If a pronounced change in eyelid or eyebrow position, a new vision-related complaint, unexpected significant weakness, or any other symptom that concerns you develops, contact our clinic. Serious symptoms such as difficulty swallowing or breathing require emergency medical evaluation.
Our approach in our Bodrum clinic
Our goal is not to standardize the facial expression; it is to create a personalized plan that preserves the person’s natural facial expressions, facial proportions, and opposing muscle balance.
Frequently asked questions
Is the effect permanent?
No. Nerve-muscle or nerve-gland communication is re-established over time, and the effect diminishes.
Is the procedure planned the same way for everyone?
No. The plan is personalized taking into account anatomy, muscle activity, functional characteristics, goals, and previous application experiences.
Why is the follow-up evaluation important?
The effect of botulinum toxin is not complete immediately. The follow-up evaluation helps assess the clinical response, symmetry, and alignment with the individual’s goals together.
