Vitamin C Suspension 30% in Silicone is a creamy serum with vitamin C in a base of lightweight silicones for a smooth, spreadable texture. It brighten, hydrate, and smooth skin with high-strength vitamin C in a base of lightweight silicones. Why Itβs Special: This treatment brightens, hydrates, and smooths the skin's surface. It reduces fine lines, wrinkles, and hyperpigmentation (such as dark spots and acne scars). Key Ingredients: L-ascorbic acid: a potent form of vitamin C with dramatic brightening and anti-aging effects. How to Use: Apply a small amount to your skin in the morning or at night after toners and water-based products. Expect a slight tingling sensation during the first 1-2 weeks of use. If irritation occurs, this product can be diluted to reduce its strength. This product should not be used at the same time as niacinamide (vitamin B3).
