Understanding Botox crows feet
Botulinum toxin injection for crow’s feet is through the injection of botox, which can block the release of acetylneurocholine, thus blocking the conduction of nerves to muscles, relaxing the excessively contracted muscles of the eyes, and thus making the dynamic wrinkles at the end of the eyes disappear, achieving The purpose of removing crow’s feet.
How are crows feet formed?
Crow’s feet are wrinkles that appear between the corners of people’s eyes and temples. Their lines are very similar to the lines on fishtails, so they are vividly called crow’s feet.
Crow’s feet are a form of oxidation lines that usually occur in people over the age of 25, and are more obvious in middle-aged and older women.
Histological manifestations are structural changes caused by elastic fiber degeneration, mainly caused by the movement of the orbicularis oculi muscle. In addition, the levator angle of the mouth, laughing muscles, and zygomaticus muscles are also involved in the process.
Something need to know about Botox crows feet
- The effects of botulinum toxin injection to remove crow’s feet are not permanent. The nerve-blocking effect of Botox cannot be maintained forever.
Generally, the nerves will begin to restore their functions in 4 to 6 months, releasing acetylcholine to restore muscle contraction function. Therefore, the effect of botulinum toxin injection to remove crow’s feet generally lasts for about 3 to 6 months. Follow-up treatment can be 3 months later.
- Botox crows feet adopt a minimally invasive injection method. The wound is only the size of a needle tip, leaving no scars, does not affect work and life, is extremely compatible with the human body, and has stable effects after injection.
- For static wrinkles that have already formed, hyaluronic acid fillers should be combined with botox injections to achieve wrinkle-removing results.
- Certain complications may also occur after botox crows feet injections, such as upper lip asymmetry, cheek sagging, dry eyes, blurred vision, photophobia, superimposed images, etc.
Injection technique of botox crows feet
The repetitive activity of the lateral orbicularis oculi muscle is the main cause of crow’s feet, so the target muscle for botulinum toxin treatment for crow’s feet is mainly the orbicularis oculi muscle.
- Crow’s feet are routinely treated with 3-point injections. When using a 30 G gauge needle, the injection depth is approximately at the level of the needle tip, and the injection is at a 30° angle from the inside to the outside (away from the orbit).
- Moderate crow’s feet require a series of 3-4 injection points approximately 1cm from the outside of the orbit. If they extend farther, another series of injection points may need to be marked on the outside.Â
- When injecting crow’s feet, the points on both sides must be symmetrical and the injection dose must be the same. Otherwise, the muscle relaxation on both sides will be inconsistent, and double vision will occur.
- The skin here is very thin, and the injection only needs to be as deep as the tip of the needle to reach the subcutaneous orbicularis oculi muscle.
Units of botox crows feet
Depth: Low-dose intradermal injection is generally used, and microinjection technology is recommended in the orbit.
Dose: 15-30 units in total.
Precautions after botox crows feet treatment
1. Slight swelling period (0 days to 3 days)
After the injection site is injected, press it with the heel of your hand for 5 to 10 minutes, apply ice for 15 to 30 minutes, apply erythromycin ointment to the needle hole, and avoid using cosmetics; keep your body upright for 6 hours after the injection, and do not lie down or do strenuous exercise; avoid Keep the injection site wet; do not massage the injection site to prevent the spread of botulinum toxin type A.
2. Effect display period (4 days to 7 days)
Within a week, no smoking, alcohol or spicy food; no strenuous exercise; no aspirin or aminoglycoside antibiotics.
3. Effect stability period (8 days to 90 days)
Within one month, it is forbidden to apply hot compresses or rub the injection site; do not squeeze or massage the injection site; keep your face relaxed and do not make too many facial expressions.
4. Degradation period (91 days ~ 180 days)
Those who want to maintain good results can undergo a second injection after three months; if you feel any discomfort, please go to the hospital for a follow-up consultation in time.
