🧪 15% pure vitamin C (ascorbic acid) optimal concentration system – Formulated within the 15–20% range for maximum skin absorption, with 15% positioned as an effective concentration

 

⚖️ Low pH absorption-optimized system (pH 3.25 ± 0.25) – Maintains pH below 3.5 to enhance vitamin C penetration into the skin

 

📊 Enhanced skin absorption performance – Vitamin C concentration in skin increases more than 2.5× at lower pH levels (around pH 3.0 vs pH 4.0)

 

🛡️ Vitamin C + E + ferulic acid antioxidant synergy – Combines 15% vitamin C with vitamin E and 0.5% ferulic acid to enhance antioxidant protection and support skin barrier function

 

📈 Antioxidant protection amplification – Up to 8× improvement in antioxidant protection factor (APF) when vitamin C is combined with vitamin E and ferulic acid

 

💧 Purified water-based delivery system – Uses a purified water base to support solubility and effective delivery of hydrophilic vitamin C

 

👁️ Transparent formulation for oxidation visibility – Near-colorless to pale yellow formula allows visual monitoring of oxidation over time

 

⚗️ Oxidation-sensitive formulation characteristics – Pure vitamin C oxidizes when exposed to light and air

 

🧴 Small-volume packaging for freshness control – 15ml container size helps reduce oxidation and supports faster usage

 

🚫 Fragrance- and artificial color-free formulation – Does not include added fragrance or artificial coloring agents

 

💧 Liquid texture with high spreadability and absorption – Lightweight liquid format spreads easily and absorbs quickly into the skin

 

🔬 Premium raw material sourcing – Uses pure vitamin C sourced from DSM UK
