Everything You Need to Know About Vitamin C 

Vitamin C is a water-soluble antioxidant that protects the skin from free radicals, which are unstable molecules. An excess of free radicals can cause changes in complexion, such as hyperpigmentation, rough texture, and accelerated collagen degradation, leading to fine lines and wrinkles. 

Vitamin C protects the skin from oxidative stress by neutralising free radicals, resulting in a brighter and more even complexion. Additionally, Vitamin C is essential for collagen biosynthesis and, when applied topically, can lead to visibly improved skin firmness. 

All skin types can benefit from Vitamin C, but the formulation base and Vitamin C complex may vary depending on the specific skin type. At RATIONALE, we offer both water and oil-based formulations to accommodate all skin types. For example, #2 The Hydragel is suitable for oily skin, while #2 The Light Crème is better suited to combination and sensitive skin types. 

We recommend incorporating Vitamin C into your skincare ritual daily to optimise defence against environmental stressors. Apply your Vitamin C formulation before applying SPF. 

The Vitality Collection advances conventional Vitamin C formulations through the strategic integration of Vitamins A and E. Vitamin A delivers robust free radical defence, while Vitamin E, a potent lipid-rich antioxidant, effectively neutralises Reactive Oxygen Species, one of the most damaging free radicals. By employing a complex of multiple Vitamin C forms rather than a single variant, these formulations optimise skin absorption, making them exceptionally adaptable to all skin types.
