Want brighter, tighter, and glowing skin? There's an ingredient for that: Vitamin C. The powerhouse skincare staple is a potent antioxidant to many skin-brightening regimens, as it interferes with irregular pigmentation and keeps inflammation at bay while promoting healthy collagen production. Unfortunately, very little vitamin C ever makes it to the skin on its own, which is why it's so important to topically apply products made with this skincare ingredient. Check out our Vitamin C collection for the best 24 vitamin C-spiked serums, moisturisers, and eye creams that are sure to leave your skin happy and bright.
