Creating a Simple Essence for Dry to Normal Skin

Combining Hyaluronic Acid Gel Base with Centella Asiatica Extract and Hydrolyzed Protein to make an essence for dry to normal skin is a good approach. These ingredients help to hydrate, soothe, and nourish the skin.

Regarding usage percentages:

• Hyaluronic Acid Gel Base: Can be used as the base at 1-100% of the formula.
• Centella Asiatica Extract: If using Centella Asiatica Extract (Madecassoside 90%) or Pure-TECA™ Centella Asiatica Extract (TECA 95%, CICA), the recommended usage rate is 0.1-2%, generally recommended at 1%.
• Hydrolyzed Protein: If using Hydrolyzed Silk Protein, the recommended usage rate is 0.1-1% (recommended 0.3-0.5%). If using Hydrolyzed Pea Protein (High-Peptide), the recommended usage rate is 0.5-5.0% (recommended 2% for skin).

Note: Add the extracts and proteins in the final step. For Hydrolyzed Protein, which is a natural protein, ensure sufficient preservatives are used in the formula.
