Vertical lines between the eyebrows, clinically known as Chuan-Zi lines, are caused by excessive contraction of the frowning muscles. They can be improved by Botox injection, hyaluronic acid injection, radiofrequency treatment, surgical treatment and other measures. 1. Botulinum toxin injection: Botulinum toxin injection is a commonly used cosmetic injection method to improve wrinkles. Excessive contraction of the muscles between the eyebrows will cause the occurrence of Chuanzihua wrinkles, so Botulinum toxin can be injected to interfere with the neuromuscular junction between the eyebrows to inhibit the excessive contraction of the frown muscles, thus effectively improving Chuanzihua wrinkles. 2. Hyaluronic acid injection: hyaluronic acid, the main component of hyaluronic acid, has good water absorption, and after local injection, it can absorb water from the skin surface and the deeper layers to help fill up the facial depressions, so as to improve the facial wrinkles effectively, so local injection of hyaluronic acid between the eyebrows can help to improve the Chuan Zig Zag Lines. 3. Radiofrequency treatment: Radiofrequency treatment can be used to improve ChuanZhiWei, its principle is mainly through high-frequency electromagnetic wave and its heat conduction effect on the dermis layer of the skin, thus promoting the regeneration and reorganization of collagen fibers and elastic fibers in the dermis layer, and ultimately achieve the effect of reducing facial wrinkles and tightening the skin. 4. Surgery: For patients with more serious wrinkles that have a greater impact on their appearance, surgical treatment can also be used to improve the appearance of wrinkles, and commonly used surgical methods include inter-brow wrinkle removal. It should be noted that patients are advised to go to regular hospitals and beauty organizations for the above operations to avoid the occurrence of adverse reactions.
