What is hyaluronic acid?

玻尿酸,又称透明质酸，是一种天然存在于人体中的高分子粘多糖，它主要存在于皮肤、眼睛、关节等部位，具有强大的保湿和润滑功能，正是因为它出色的保湿能力，玻尿酸在医美领域被广泛应用。

In the skin, hyaluronic acid can absorb and lock in a large amount of water, maintain the moisture balance of the skin, thereby maintaining the fullness and elasticity of the skin. As we age, the content of hyaluronic acid in the human body will gradually decrease, resulting in dry, slack and wrinkles on the skin., hyaluronic acid has become a "star product" for medical beauty filling.

Types and uses of hyaluronic acid

Hyaluronic acid is not "one" product, but has multiple specifications and molecular weights. Hyaluronic acid with different molecular weights is suitable for different parts and effects:

1. Small molecule hyaluronic acid: It is mainly used on delicate parts such as lips and lacrimal grooves. It can naturally integrate into the skin, and the effect is delicate and natural.

2. 中分子玻尿酸: Suitable for medium-depth wrinkles such as decree lines and puppet lines. It has both support and a sense of nature.

3. macromolecular hyaluronic acid: Mainly used for deep filling, such as facial contours, temples, etc., can provide strong support and long-lasting effects.

Hyaluronic acid can also be customized according to the needs of different parts, such as facial filling, lip augmentation, nose augmentation, chin filling, etc.

The principle of hyaluronic acid filling

The principle of hyaluronic acid filling is very simple: hyaluronic acid products are injected into the dermal layer or subcutaneous tissue of the skin by injection to fill the sunken areas caused by age or trauma, thereby restoring the fullness and elasticity of the skin.

Hyaluronic acid itself has good biocompatibility and can integrate well with human tissues without causing obvious rejection reactions. The molecular structure of hyaluronic acid can absorb and lock in moisture, keeping the skin moist and elastic.

Effect and duration of hyaluronic acid filling

玻尿酸填充的效果因人而异,通常可以维持6个月到2年不等，影响效果持续时间的因素包括：

1. ha has a molecular weight：大分子玻尿酸的持续时间更长，小分子则相对较短。

2. 注射部位: Dynamic areas of the face (such as lips and eyes) metabolize quickly and the effect time is short.

3. 个人体质：新陈代谢快的人效果时间较短，新陈代谢慢的人则相对较长。

4. postoperative care：良好的术后护理可以延长效果时间。

The two can be used in combination to achieve better cosmetic results.
