This hero product from SkinCeuticals is pretty much the OG of vitamin C serums. Using 15 percent pure vitamin C, plus vitamin E and ferulic acid, this face serum neutralizes damaging free radicals while also encouraging ingredients to work synergistically to boost the effectiveness of other antioxidants within the formula. Even more impressive, this vitamin C serum's benefits remain effective for a minimum of 72 hours after absorption.

Combining five different sources of vitamin C, this ultra-potent, citrus-smelling serum instantly absorbs and penetrates the skin to boost collagen and promote cell renewal for a brighter complexion. The oil-free formula is also loaded with moisture-binding ingredients so skin will stay hydrated for longer, making this vitamin C serum the perfect product to help promote skin's healing of sun damage, scarring or even burns.

Sometimes vitamin C serums can feel a bit too, well, watery, but not this one by Drunk Elephant. With a gel-like texture, this newly improved formula isn't only jam-packed with vitamin C, it also contains fruit enzymes like pumpkin ferment and pomegranate enzymes that work to dissolve dead skin cells for a smoother feel. Also, considering vitamin C loses its efficacy when exposed to light or after oxidation, Drunk Elephant designed this product's packaging to be an opaque, airless pump so that the formula stays effective for longer.

Whether you use this vitamin C serum on its own after cleansing or mix a few drops of it into your favorite moisturizer, you'll get unparalleled brightening after-effects while also slowly diminishing unwanted fine lines and wrinkles.

Consider this a daily multivitamin with an extra dose of vitamin C for your skin. Formulated with three different forms of vitamin C as well as soothing bamboo extract and chamomile extract, this serum acts to reverse the visual effects of environmental damage. Fine lines, wrinkles and hyperpigmentation won't stand a chance against this multi-purpose product.
