Moisturizing Serum Formulation

Regarding your question about Hyaluronic Acid (Standard Molecule), when dissolved in water according to the instructions, it will result in a clear gel. This makes it suitable for creating a clear moisturizing serum as you intended.

As the staff mentioned, combining several moisturizing actives at lower concentrations can often yield better results as different ingredients benefit different skin types. If you are looking for other water-soluble moisturizing actives that are suitable for a clear serum, here are a few recommendations:

• Advanced Moisture Complex: This is a complex blend of moisturizers that provides immediate and long-lasting hydration. It is a clear liquid and dissolves easily in water, helping to prevent water loss from the skin.
• VersaMoist™: A clear liquid soluble in both water and oil, it enhances skin penetration of other ingredients, provides versatile moisturizing, and can help reduce stickiness in formulations.
• TransMoist™: This clear liquid dissolves in water and offers moisturizing benefits while helping the formula absorb faster into the skin. It works particularly well when combined with Glycerin.
• WaterLock™: A clear liquid that dissolves in water, it forms a protective layer on the skin to prevent water loss and provides a smooth feel. It adheres well to the skin and can also help reduce irritation from detergents.

These ingredients are water-soluble and have a clear appearance, making them excellent additions or alternatives for your clear moisturizing serum formulation alongside or in combination with Hyaluronic Acid.
