Recommended Ingredients and Percentages for Very Dry Skin Serum

For very dry skin, a serum should focus on two main aspects: Deep Hydration (adding water to the skin) and Barrier Repair (preventing water from evaporating).

Here are the recommended ingredients and their usage percentages for a high-performance serum:

1. Deep Hydration & Water Retention

• Hyaluronic Acid (Standard Molecule): Acts as a humectant to hold moisture on the skin surface.
  • Recommended Usage: 0.2% - 0.5%
• MOIST72™ (Saccharide Isomerate): Provides long-lasting hydration for up to 72 hours by binding to the skin.
  • Recommended Usage: 3% - 5%
• Vitamin B5 (Panthenol): Helps soothe dry, irritated skin and improves moisture levels.
  • Recommended Usage: 2% - 3%

2. Barrier Repair (Essential for very dry skin)

• Skin-Barrier™ (Ceramides Liposome): Contains Ceramides, Cholesterol, and Fatty Acids to mimic the skin's natural barrier, preventing "Transepidermal Water Loss" (TEWL).
  • Recommended Usage: 3% - 5%

3. Serum Base

• Silky Serum Base: A ready-to-use base that provides a smooth, non-sticky feel, ideal for incorporating the active ingredients above.

Example Formulation Guide (Total 100%)

Instructions:

• Mix the active ingredients into the serum base one by one, stirring until homogeneous.
• Since this formula contains several water-soluble actives, ensure your base includes a preservative system, or add a broad-spectrum preservative to maintain stability.
