What is hyaluronic acid?
玻尿酸，又称为透明质酸，是一种天然存在于人体中的高分子粘多糖，主要存在于皮肤、结缔组织和眼睛的玻璃体中，它具有强大的保湿和填充功能，能够吸收大量水分,保持皮肤的水分平衡和弹性。
In the field of medical beauty, high-purity hyaluronic acid is extracted and made into an injection product, which can be used for facial filling, shaping and improving wrinkles.
Core principles of hyaluronic acid
玻尿酸注射的核心原理是通过将玻尿酸产品注射到皮肤的真皮层或皮下组织，填补因年龄增长、collagen流失、面部结构改变而产生的皱纹和凹陷部位,从而达到塑形和美化面部的效果。
Hyaluronic acid is gradually absorbed in the body, so the effect is not permanent. The general maintenance time is 6 months to 1-2 years, depending on the product type, injection site, and personal constitution.
Choice of hyaluronic acid products
There are many types of hyaluronic acid products on the market, mainly classified based on molecular weight and crosslinking technology:
molecular weight
- Polymer hyaluronic acid: Mainly used for deep filling, such as chin filling, temple filling, etc., with long-lasting effect.
- 中分子玻尿酸: Suitable for medium depth filling such as decree lines and tear grooves, with moderate effect.
- Small molecule hyaluronic acid: Mainly used to replenish water and improve fine lines. The effect is light and suitable for daily water-light acupuncture treatment.
crosslinking technique
Crosslinking technology is one of the key factors determining the performance of hyaluronic acid products. The higher the degree of cross-linking, the stronger the stability of the product and the longer the maintenance time, but the harder the texture will be. Common cross-linking technologies include:
- BDDE Cross-linking: Long-lasting effect and suitable for deep filling.
- TMA crosslinking: Soft texture, suitable for fine facial filling.
- No or low crosslinking: It is mainly used for replenishing water with water-light needles, with short effect.
