Can Stabilized Vitamin C (Natural-C Glycol™) Serum be used directly on the skin?

Yes, Stabilized Vitamin C (Natural-C Glycol™) Serum can be applied directly to the skin without needing to mix it with water or other ingredients. It is formulated as a finished serum with a 15% concentration of Vitamin C (L-Ascorbic Acid).

Key points for use:

• Direct Application: It is designed to be used at 100% concentration as a standalone serum.
• Stability: It is not recommended to mix in additional ingredients (except for fragrance or color at very low levels), as this may affect the stability of the Vitamin C.
• pH Level: The serum has a pH range of 2-3, which is optimal for Vitamin C stability and skin penetration. However, users with sensitive skin may experience a slight tingling sensation upon application.
• Storage: To maintain the efficacy of the Vitamin C, store the product in a cool, dark place away from direct sunlight.
