Which type of Hya is suitable for a face mask serum?

To make a face mask serum that provides full hydration and works well with a sheet mask, you can choose from several types of Hyaluronic Acid (Hya), depending on your needs and preparation method.

Hyaluronic Acid comes in various molecular sizes, each offering different benefits:

• Small Molecule (e.g., Super Low Molecule 7000 daltons): Can penetrate deep into the skin, helping to increase moisture in the deeper skin layers. It is suitable for focusing on anti-aging and providing internal hydration, but it does not create a gel texture or coat the skin.
• Standard Molecule: Cannot penetrate deep skin layers but helps hydrate the outer skin area. It can form a slight gel and lightly coat the skin.
• Large Molecule: Also cannot penetrate deep skin layers but provides hydration and creates the best film coating on the skin among single-molecule types. It helps reduce water loss and makes the skin appear smoother, creating a good gel texture.

For a face mask serum, it is recommended to use Hyaluronic Acid that provides hydration across multiple skin layers and has a suitable texture for a serum.

Recommended Options:

1. 4D Hyaluronic Acid: This is a very convenient option as it combines 4 molecular sizes of Hyaluronic Acid (small, medium, large, and cationic). Therefore, it provides comprehensive hydration to all skin layers, from the outer to the innermost. It has a thick gel texture, is easy to use, and can be mixed directly into water-based formulas. It is suitable for making a high-performance, all-around serum mask.
2. Hyaluronic Acid Gel Base: For even greater convenience, you can use Hyaluronic Acid Gel Base as the main base. This base already contains 4 molecules of Hyaluronic Acid. You can directly add desired extracts or active ingredients without needing to create the gel base yourself.
3. Combining Multiple Molecular Sizes: To achieve both external and internal hydration, you can choose to use Large Molecule or Standard Molecule Hyaluronic Acid to create the gel texture and coat the skin, combined with a very small molecule Hyaluronic Acid (e.g., Super Low Molecule 7000 daltons) for better penetration into the skin. This method may require time to dissolve the powdered Hyaluronic Acid in water first.

The choice depends on the ease of preparation and the desired properties. If you prioritize ease and comprehensive benefits, 4D Hyaluronic Acid or Hyaluronic Acid Gel Base are good options. However, if you want to customize the formula and control the ratio of each molecule, combining different sizes of Hyaluronic Acid is another interesting approach.
