Before exploring various issues, let's understand what hyaluronic acid is: Also known as hyaluronic acid (HA), it is a natural polysaccharide.appearing as a transparent, viscous gel-like substance. As a high-molecular-weight polysaccharide, it consists of linear chains of disaccharide units composed of glucuronic acid and N-acetylglucosamine, with an average molecular weight ranging from 100,000 to 10,000,000 Daltons. It naturally exists within human skin tissue, filling the spaces between cells and collagen fibers.
Four Criteria for Authenticating Hyaluronic Acid:
Criterion 1: Restylane® 2
On December 15, 2008, Restylane® 2 received approval from China's State Food and Drug Administration (SFDA) and obtained the Medical Device Registration Certificate of the People's Republic of China, registration number: Guoshiyaojian Xie (Jin) Zi 2008 No. 3643554.Any other brands or models are not officially approved for use in China.
Criterion 2: Sterile Sealed Packaging
Legitimate hyaluronic acid is directly packaged in syringes with sterile, sealed packaging. Before use, simply open the packaging, attach the injection needle, and administer. It is absolutely not repackaged product.
Evidence 3: Minimum Volume of 0.5cc
According to Yuhwa Biotech, the authorized distributor of legal hyaluronic acid products, the minimum volume for currently imported hyaluronic acid packaging is 0.5cc, specifically for Touch low-density hyaluronic acid. No syringes contain less than 0.5cc.
Evidence 4: Pricing
Hyaluronic acid injections constitute a medical procedure. In Taiwan, the standard price per milliliter ranges from NT$25,000 to NT$30,000. In mainland China, prices typically fall between NT$4,600 and NT$8,800 per vial. Therefore, be wary of beauty centers offering unusually low prices, as they may be using illegal silicone substitutes.Consumers seeking injections should visit licensed hospitals for greater assurance.
For medical aesthetics, always choose institutions holding a valid Medical Institution Practice License with approved aesthetic medicine departments and services. Never compromise your health for convenience.
Three primary applications of hyaluronic acid injections:
1. Wrinkle reduction: Hyaluronic acid is a naturally occurring component in the human body. Its molecular structure forms robust bonds, creating a durable filler that combats wrinkles. Restylane hyaluronic acid, for instance, integrates with the body's existing hyaluronic acid upon injection. This fusion smooths and plumps wrinkles, delivering rapid and noticeable results that effectively address age-related concerns.Restylane Hyaluronic Acid is widely used to eliminate static facial lines, including crow's feet, tear troughs, under-eye bags, nasolabial folds, and laugh lines.
II. Non-Invasive Hyaluronic Acid Contouring: Hyaluronic acid's remarkable tissue-filling properties make it widely used in minimally invasive procedures such as: - Reducing under-eye bags - Augmenting the eye area - Shaping cheekbones - Plumping lips - Refining lip contours - Enhancing the chin - Elevating the nasal bridge - Refining nasal contours - Augmenting the cheeks
III. Hyaluronic Acid Micro-Sculpting: Naturally present in human skin, hyaluronic acid is recognized as a superior hydrating agent—a single molecule can bind 500 times its weight in water. Injecting Restylane® II hyaluronic acid directly replenishes skin moisture at its source, enhancing long-term hydration retention. This comprehensively improves skin softness, elasticity, smoothness, radiance, and clarity.
