With glabellar lines between the eyebrows, wrinkle injections usually begin to show results in about a week. Wrinkle injections are usually botulinum toxin and hyaluronic acid. Botulinum toxin can inhibit the release of transmitters from nerve cells, preventing muscle contraction to improve the effect of dynamic wrinkles. Hyaluronic acid fills in the subcutaneous tissue to increase volume and improve static wrinkles. After the injection, the effect usually begins to be seen in about a week, the effect reaches its maximum in about a month, and the effect can be maintained for about 6-8 months. Multiple injections are usually required to maintain the effect. The side effect of wrinkle injections is that they may cause localized nodules or infection. People suffering from facial or systemic infections or allergies are generally not recommended to take wrinkle injections, as well as diabetics and patients with myasthenia gravis, breastfeeding and pregnant women. If there is a desire for treatment, it is recommended that patients go to a regular medical institution to avoid adverse consequences.
