Grittiness disappears as it absorbs - *Best for*: Non-sensitive skin used to Vitamin C. Great for dullness, uneven tone, and fine lines This is one of The Ordinary’s strongest Vitamin C products. The silicone base keeps the pure L-Ascorbic Acid stable without water, but it can cause a tingling or stinging sensation at first. That’s normal. Use at night after water-based serums, before oils. Start 2-3x per week if you’re new to high % Vitamin C. Can be used in the AM but expect it to pill under makeup. Daily SPF is a must since Vitamin C boosts sun protection but also increases photosensitivity.
