Problems solved by technology

The long-term safety of cross-linked hyaluronic acid residual cross-linkers is still a concern, however, a single hyaluronic acid has a short residence time in the body and requires repeated injections to maintain cosmetic effects
[0006] In addition, the above-mentioned injectable gel containing cross-linked hyaluronic acid and microparticles such as hydroxyapatite faces two main problems in industrial production: 1) In order to ensure that the injectable gel is free of air bubbles, it needs to

Example Embodiment

[0053] Example 1 Preparation of a single gel composition (HP) with 1%, 2%, 4% hyaluronic acid and 30% hydroxyapatite microparticles (comparative gel).

[0054] An HP gel composition with a sodium hyaluronate concentration of 1% was prepared.

[0055] Add 1g of HA to 100.9g of solution A under slow stirring, fully wet and swell, and let it stand for 6 hours to obtain a clear and transparent solution or gel. Subsequently, 43.67g of hydroxyapatite is added to grind or stir for 10 minutes to make it mixed into a uniform phase.

[0056] Weigh the formula HA, hydroxyapatite and solution A according to the formula in Example 1 of Table 1, and the preparation method is the same as the preparation method of the HP gel composition of 1% sodium hyaluronate.

[0057] Table 1: The formula composition of Examples 1, 2, 3

Example Embodiment

[0059] Example 2 Preparation of a single gel composition (MP) with 1%, 3%, 5% methylcellulose (MC) and 30% hydroxyapatite (CaHAP) microparticles (comparative gel).

[0060] The specific formula is shown in Example 2 of Table 1. The preparation method is the same as that of the HP gel composition of 1% sodium hyaluronate in Example 1. Sodium hyaluronate is replaced by sodium methylcellulose in this example. can.

Example Embodiment

[0061] Example 3 Preparation of a single gel composition (CP) with 2%, 4%, 6% carboxymethylcellulose sodium (CMC-Na) and hydroxyapatite (CaHAP) microparticles (comparative gel)

[0062] The specific formula is shown in Example 3 in Table 1. The preparation method is the same as the preparation method of the HP gel composition of 1% sodium hyaluronate in Example 1. Sodium hyaluronate can be replaced by the methyl cellulose in this example. .

Abstract

The invention discloses an injected face filler compound gel for cosmetic plastic surgery and a preparation method thereof. The injected face filler compound gel is used for plastic surgery and is mainly contains gel formed by organically mixing non-crosslinking sodium hyaluronate and cellulose ethers and optional fine particles such as hydroxyapatite (CaHAP) fine particles. The injected face filler compound gel for cosmetic plastic surgery is uniform in texture, can stabilize the fine particles for a long time, for example, the hydroxyapatite uniformly dispersed in the gel, has expected rheological behavior (high elasticity modulus and high dynamic viscosity) and meanwhile is suitable for industrial filling and clinic injection.

Description

technical field [0001] The invention belongs to the technical field of cosmetic plastic surgery, and in particular relates to an injection-type facial filler composition gel for cosmetic plastic surgery and a preparation method thereof. Background technique [0002] Skin naturally loosens and wrinkles over time, especially facial contour aging, including visible skin lines, deep nasolabial folds, frown lines, marionette lines, buccal seam lines, mouth circumference wrinkles, temporal Collapse etc. Similarly, the collapse of the bridge of the nose due to congenital or trauma, as well as improper browbones and chins, etc. have brought troubles and pains to people. Beauty is an eternal topic and goal pursued by human beings. How to effectively delay skin aging and beautify the appearance is still a problem that people continue to explore and solve. [0003] Injection of facial fillers for aesthetic plastic surgery can effectively solve the above problems and support the colla...
