There are many people with sunken foreheads, causing defects in heaven. So, what? Experts point out that it can be corrected by injection of forehead enlargement, which specifically includes the following aspects: Forehead widening with hyaluronic acid injection in Taiwan Recently, macromolecular hyaluronic acid (also known as SubQ) has been approved and is specifically used for injection into soft tissue. It can be used to augment cheeks, temples and forehead. Since macromolecular hyaluronic acid is not easily metabolized in the human body, the effect is long-lasting and can last for 2-3 years. Since it will eventually be catabolized, it is still considered a safer filler. Collagen Injection to Widen the Forehead After the advent of hyaluronic acid, collagen (collagen) was relegated to the sidelines, and everyone almost forgot its existence. Recently, the dosage form has been increased to 3.5% concentration, which extends its effect to 6-8 months. What makes it favored by plastic surgeons is that collagen can be injected in a very shallow layer without causing irregular granular shapes. That is, it is easier to shape after injection. Therefore, if you want to get a full forehead, Don’t forget about the benefits of collagen for the superficial layers, too. AQUAMID Injection for Forehead Widening As for the permanent injection AQUAMID, it has recently been approved by the Department of Health. Since its effect is said to last for 5-7 years, plastic surgeons are somewhat wary of this long-lasting injection due to the indiscriminate use of silicone by non-professionals 20-30 years ago, which caused nightmares for many people. However, if applied by a professional doctor in the appropriate location, long-lasting fillers will naturally have a permanent effect. GORTEX (Polytetrafluoroethylene) and MEPORE (Polyethylene) are both synthetic materials and are relatively expensive.
