Introduction

In general, hyaluronic acid contains ingredients such as hyaluronic acid, glucuronic acid, N-acetylglucosamine, hydrolase, sodium polyglutamate, and others. Different types of hyaluronic acid have varying effects in skincare and cosmetic procedures. When using hyaluronic acid products, it is recommended to select the appropriate product type and application method based on individual skin type and needs.

Generally, hyaluronic acid contains ingredients such as hyaluronic acid, glucuronic acid, N-acetylglucosamine, water-decomposing enzymes, sodium polyglutamate, and others. The specific analysis is as follows:

1. Hyaluronic Acid

This is the main component of hyaluronic acid, an acidic mucopolysaccharide composed of disaccharide units made up of D-glucuronic acid and N-acetylglucosamine, forming a glycosaminoglycan. Naturally present in human skin, hyaluronic acid has strong water-absorbing and moisturizing properties. It helps improve skin nutrient metabolism, making the skin soft, smooth, reducing wrinkles, enhancing elasticity, and preventing aging.

2. Glucuronic Acid

As an essential component of hyaluronic acid, glucuronic acid plays a key role in hyaluronic acid products. It combines with N-acetylglucosamine to form the disaccharide units of hyaluronic acid, contributing significantly to its powerful moisturizing and hydrating effects.

3. N-Acetylglucosamine

This is another key component that constitutes hyaluronic acid. Together with glucuronic acid, it forms the disaccharide units that build the molecular structure of hyaluronic acid. N-acetylglucosamine also has certain physiological functions in the human body, such as participating in the synthesis of cartilage and connective tissues.

4. Water-Decomposing Enzymes

In some hyaluronic acid products, water-decomposing enzymes may be added. These enzymes help enhance the absorption and utilization of hyaluronic acid by the skin, thereby improving its moisturizing and hydration effects.

5. Sodium Polyglutamate

Sodium polyglutamate is a high-molecular-weight polymer with excellent hygroscopic and moisture-retaining properties, capable of increasing the water content of the skin.

Different types of hyaluronic acid offer varying effects in skincare and cosmetic procedures. When using hyaluronic acid products, it is recommended to select the appropriate product type and application method based on individual skin type and needs.

What are the contraindications after rhinoplasty?

The methods of rhinoplasty include implant rhinoplasty, costal cartilage rhinoplasty, and hyaluronic acid injection rhinoplasty. These procedures primarily improve the nasal shape by augmenting the external nose with autologous or allogeneic tissues. Postoperative contraindications include avoiding strenuous exercise, nasal trauma or pressure, strictly avoiding contact with water and wound contamination, refraining from consuming spicy foods as well as alcohol and tobacco, and avoiding the unauthorized use of medications or skincare products.
