How long does the effect of a single eye wrinkle injection last?

Generally, eye wrinkle injections refer to botulinum toxin injections for the removal of eye wrinkles. Botulinum toxin injections for eye wrinkles typically last for 3-6 months. Botulinum toxin injections work by precisely injecting botulinum toxin into specific facial muscles around the eyes, inhibiting the release of acetylcholine at the neuromuscular junction, blocking nerve impulse transmission, and causing muscle relaxation and paralysis, thereby reducing eye wrinkles caused by facial muscle contractions. The usual reference price for botulinum toxin injections is 800-1500 yuan per session. Improvement is usually noticeable 3-7 days after the procedure, although side effects such as redness, swelling, and itching may occur. A detailed explanation is as follows:

Botulinum toxin is gradually metabolized and decomposed in the body over time. As neuromuscular conduction function slowly recovers, the muscles begin to contract again, leading to the reappearance of wrinkles. This results in a limited duration of effect, usually 3-6 months. Additionally, individual differences can affect the duration of the effect—for example, younger individuals with faster metabolism may experience quicker drug metabolism, resulting in a relatively shorter duration, while older individuals with slower metabolism may experience a slightly longer duration of effect.

It is recommended to visit a legitimate hospital and undergo the procedure under the guidance of a qualified physician to ensure safety and effectiveness. After the procedure, avoid massaging, rubbing, or applying heat to the injection site to prevent the spread of the medication, which could affect the results or worsen local swelling. It is also important to keep the injection site clean and dry, avoid contact with water, and prevent infection.
