What is cross-linked hyaluronic acid?
Cross-linked hyaluronic acid, as the name suggests, is hyaluronic acid treated through crosslinking technology. Cross-linking refers to connecting hyaluronic acid molecules through chemical bonds to form a three-dimensional network structure. This treatment method not only enhances the stability of hyaluronic acid, but also improves its water-retaining ability and shaping ability.
After ordinary hyaluronic acid enters the human body, it will be gradually absorbed over time, and the effect usually only lasts for 6 months to 1 years. However, due to changes in the molecular structure, cross-linked hyaluronic acid absorbs slowly, so the effect is more long-lasting, generally lasting for 1 years to 1 and a half years or even longer.
The principle of cross-linking hyaluronic acid
The core of cross-linking hyaluronic acid lies in the "cross-linking agent". The cross-linking agent is a chemical substance that can form a bridge between hyaluronic acid molecules and turn the originally freely flowing hyaluronic acid molecules into a stable gel-like substance. Common cross-linking agents include BDDE (1,4-butanedimethoxydiethylene glycol), EDC (1-ethyl-3-(3-dimethylaminopropyl) carbonyldiimidazole hydrochloride), etc.
The degree of crosslinking is a key factor determining the performance of hyaluronic acid. The higher the degree of crosslinking, the stronger the hardness and stability of hyaluronic acid, but the plasticity will be reduced accordingly; the lower the degree of crosslinking, the softer the hyaluronic acid will be and the shaping effect is better, but the maintenance time is relatively short.
Types and uses of cross-linked hyaluronic acid
Cross-linked hyaluronic acid can be divided into various types according to its crosslinking degree and use, and is suitable for different parts and needs:
Slightly cross-linked hyaluronic acid: Mainly used to fill lips, fine lines, decree lines and other fine areas. The effect is natural and the recovery period is short.
Moderately crosslinked hyaluronic acid: Suitable for filling mid-depth areas such as forehead, temples, and chin. The effect is long-lasting and natural.
重度交联玻尿酸: It is mainly used for rhinoplasty, chin augmentation and other parts that require strong support. The effect is remarkable, but the shaping is more difficult.
reversibly crosslinked hyaluronic acid: An emerging type in recent years. Its cross-linked structure can be reversed under certain conditions, making it easy to adjust or dissolve, and suitable for beauty seekers who need flexible shaping.
Advantages of cross-linked hyaluronic acid
lasting effect：交联后玻尿酸的分子结构更稳定，吸收速度慢,效果维持时间更长。
Strong plasticity: The gel-like structure of cross-linked hyaluronic acid allows it to be better shaped, especially in nose augmentation, chin augmentation and other areas.
high safety：经过交联处理的玻尿酸在体内逐渐降解，不会引起明显的排异反应,安全性较高。
Short recovery period: After cross-linked hyaluronic acid injection, the recovery period is short and daily activities can usually be resumed within a few days.
Precautions for cross-linking hyaluronic acid
Although the effect of cross-linking hyaluronic acid is significant, the following points should be paid attention to when selecting and using:
Choose regular products: The quality of cross-linked hyaluronic acid is directly related to the injection effect and safety. You must choose a regular brand and medical institution.
Operation by professional doctor: Cross-linked hyaluronic acid injection requires an experienced doctor to ensure natural and symmetrical shaping.
individual differences: Each person's facial structure and skin condition are different, and the injection effect will also vary. The appropriate type of hyaluronic acid needs to be selected according to your personal situation.
postoperative care: Avoid pressing or rubbing the injection site after injection to prevent the hyaluronic acid from being displaced or deformed.
The difference between cross-linked hyaluronic acid and ordinary hyaluronic acid
| project | crosslinked hyaluronic | Ordinary hyaluronic acid |
|---|---|---|
| structure | 交联后形成三维网络 | Free flowing, not crosslinked |
| duration of effect | 1-1. 5years or even longer | 6Month-1 Year |
| Shaping ability | Strong, suitable for nose augmentation and chin augmentation | Weak, suitable for filling fine lines |
| absorption rate | slower | rapid |
| hardness | higher | lower |
Future development trend of cross-linked hyaluronic acid
With the continuous development of medical beauty technology, cross-linked hyaluronic acid is also constantly innovating. Cross-linked hyaluronic acid may develop in the following directions:
Intelligent crosslinking technology: Through intelligent cross-linking technology, the controllable release of hyaluronic acid in the body is achieved and the effect time is prolonged.
Biodegradable crosslinker: Use safer, degradable crosslinking agents to reduce the burden on the body.
personalized customization: Customize hyaluronic acid products with different crosslinking degrees according to the facial characteristics and needs of beauty seekers.
