What is Botulinum Toxin for Crow’s Feet Lines?
In botulinum toxin applications, the aim is to temporarily and controllably modulate the activity of the target muscle or gland. The result varies according to individual anatomy, muscle strength, application area, and clinical goal.
Why do crow’s feet lines become prominent?
During smiling and squinting, the activity of the orbicularis oculi muscle creates radial lines at the outer edge of the eye. Skin thinning and sun damage can contribute to lines being visible even at rest.
Why is the smile important in planning?
The eye area is not merely a wrinkle area; it is an important part of the smile. For this reason, rather than completely erasing the lines, the aim is to reduce excessive muscle activity while preserving the natural smile, lower eyelid support, and the overall balance of the face.
What does botulinum toxin not change?
Under-eye bagging, pigmentation, prominent skin laxity, or volume loss involve different mechanisms, and the same benefit is not expected from the same treatment to the same extent.
Who can be evaluated for it?
Lower eyelid support, history of dry eyes, prior surgeries, and smile patterns are evaluated.
Pre-procedure evaluation
In our clinic, our approach is to evaluate the history, dynamic examination, facial or functional anatomy, asymmetry, prior applications, and the individual’s goals together, rather than applying a standard dot pattern. In the evaluation, the person’s medical history, anatomical characteristics, prior applications, and expectations from the treatment are addressed together.
Scientific evidence
This application area is evaluated based on the effect of botulinum toxin that temporarily reduces muscle activity. Scientific publications and expert consensuses show that patient selection and anatomical evaluation are important in terms of outcome and safety.
When does the effect start and how long does it last?
The effect usually begins to appear within the first few days and becomes prominent 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.
Potential side effects
Pain, tenderness, bruising, or headache may be seen at the injection site. Area-specific effects such as temporary asymmetry, unintended weakness in neighboring muscles, changes in eyelid/eyebrow position, changes in oral functions, or difficulty swallowing may occur. Rare but serious generalized muscle weakness, difficulty swallowing, or difficulty breathing require urgent medical evaluation.
Who may it not be suitable for?
Active infection in the application area, known hypersensitivity to botulinum toxin components, and certain neuromuscular diseases require special attention. Pregnancy/breastfeeding, anticoagulant use, aminoglycosides or medications that can affect neuromuscular transmission, and prior botulinum toxin applications should be shared with the physician.
Things to consider after the procedure
It is appropriate not to unnecessarily rub or intensely manipulate the application area on the same day. Short-term redness, tenderness, or small bruises may be seen at the injection sites. A return to daily life is often possible in a short time; if heavy exercise, intense heat exposure, or another facial procedure is planned, follow your physician’s recommendation according to your personal situation. Because the effect is not immediately complete, early decisions regarding symmetry should not be made in the first hours or first days. If a prominent eyelid or eyebrow position change, a new complaint related to vision, unexpected prominent weakness, or any other symptom that concerns you develops, contact our clinic. Serious symptoms such as difficulty swallowing or breathing require urgent medical evaluation.
Our approach in our Bodrum clinic
Our goal is not to standardize facial expression, but to create an individualized 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 re-establishes over time, and the effect diminishes.
Is the application planned the same way for everyone?
No. The plan is individualized by taking into account anatomy, muscle activity, functional characteristics, goals, and prior application experiences.
Why is the follow-up evaluation important?
The effect of botulinum toxin is not completed immediately. The follow-up evaluation helps to evaluate the clinical response, symmetry, and alignment with the individual’s goals together.
