⸻
🧪 Key Ingredients & Efficacy
•25% Pure Vitamin C (Ascorbic Acid) – delivers brightening, antioxidant protection, and collagen support.  
•2% Vitamin C Derivative (Ethyl Ascorbyl Ether) – offers stable, long-lasting brightening.  
•2% Vitamin B5 (Panthenol) – hydrates and soothes the skin barrier.  
•Additional actives – includes adenosine (firmer texture), turmeric & broccoli extracts (antioxidant/soothing), allantoin (calming), coenzyme Q10, caffeine, and ferulic acid for multi-level support.  
Clinical results show up to 25% improvement in dark spots visibility within just 3 days, along with gains in tone, elasticity, and texture. 
💧 Texture & Sensation
Lightweight and fast-absorbing, this gel-like ampoule leaves a hydrating, non-sticky finish. While it may produce a mild tingling (common with high‑dose vitamin C), it’s formulated at an optimal pH to balance absorption and minimize irritation.
