Botulinum Toxin Injections Around the Eye Corners: A Popular Cosmetic Procedure for Improving Crow's Feet

Botulinum toxin injections have become a popular cosmetic technique for improving crow’s feet – the fine lines and wrinkles that form around the outer corners of the eyes. This treatment works by blocking the transmission of nerve signals to the muscles, thereby temporarily relaxing them and reducing the formation of dynamic wrinkles. In particular, it reduces the activity of the orbicularis oculi muscle (especially its lateral portion), which is primarily responsible for the appearance of crow’s feet.

Injection Techniques and Points:
Injection Points: The injections are typically administered in the canthal region on both sides of the eyes. These points are carefully chosen to cover the area where crow’s feet commonly occur, while minimizing any impact on natural facial expressions.
Injection Method: An intradermal injection technique is used, which helps reduce the risk of bruising, as the injections are performed within the skin rather than deep into the muscle.

Treatment Results and Duration:
The improvement usually begins to appear a few days after the injection, with the optimal results forming in about two weeks. The effects can last anywhere from three to six months, and some patients may opt for periodic injections to maintain the results.

Side Effects and Risk Management:
Common Side Effects: The most common side effects include mild bruising or small hematomas around the eyes, which typically resolve naturally within a few days.
Rare but Important Risks: If the toxin is inadvertently injected into the lower part of the zygomaticus major (which helps lift the upper lip), it could lead to drooping of the mouth corners, thus affecting natural facial expressions. This underscores the importance of choosing an experienced doctor.

Post-Treatment Care:
1. Avoid vigorous exercise within the first 24 hours after treatment to minimize the risk of the toxin spreading to unintended areas.
2. Do not massage or touch the injection sites to prevent the toxin from migrating to non-targeted muscles.
3. Applying a cold compress within the first 30 minutes after the injection can help reduce swelling and bruising.

Professional Recommendations:
1. Undergo a detailed facial assessment to determine the optimal injection points and dosage; this is crucial to avoid unnecessary side effects and to achieve the best results.
2. Since every individual’s facial structure and muscle activity are different, a personalized treatment plan is essential.

Long-Term Considerations:
Although botulinum toxin injections are considered safe, long-term use may lead to muscle atrophy or the development of resistance. Thus, it should be administered cautiously under a doctor's guidance. Combining this treatment with other non-invasive procedures (such as laser or radiofrequency therapies) can offer a more comprehensive anti-aging effect.

In summary, this treatment not only improves the appearance of crow’s feet but also significantly enhances overall facial aesthetics, boosting self-confidence. Ensuring that the procedure is performed by a professional and following proper post-treatment care guidelines are key to maximizing both safety and efficacy.
