Science behind this product: Vitamin C is a proven skin-brightener and antioxidant for decades. It boosts collagen formation and effectively targets visible signs of ageing, giving skin the much-needed glow. The effectiveness of Vitamin C majorly depends upon the concentration of pure Vitamin C delivered to your deeper layer of skin. If a serum delivers 8-10 % of pure Vitamin C right into the dermis, it works like a magic wand. However, Vitamin C is highly unstable in its purest form (L-Ascorbic Acid) and loses its efficacy when exposed to air or light. Minimalist Vitamin C serum is formulated with a stable Vitamin C derivative, 10% Ethyl Ascorbic Acid that is closest to pure Vitamin C (L-Ascorbic Acid) in molecular size and weight. With similar molecule size and 86% pure Vitamin C content it delivers maximum benefits of Vitamin C without getting bad or losing efficacy till the last drop (unlike other Vitamin C serums). A Centella water based formula that soothes skin and reduces irritation making it suitable for all skin types. Uniquely formulated with 1% Acetyl Glucosamine (AG) that not only lightens skin tone, it also promotes synthesis of Hyaluronic Acid to improve skin hydration. Lastly, AG improves your natural cell-turnover, giving you a bright & glowing complexion.
