Look no further than this brightening formula from One Love Organics. The brand boasts that 100 percent of the ingredients are of natural origin and it uses botanicals to nourish the skin for a more evenly toned complexion. Organic green tea and vitamin E round out the formula to boost the effectiveness of the vitamin C, making this serum one fantastic skin brightener.

Meet your newest glow-booster -- an oil-free, concentrated vitamin c treatment for skin that targets dull complexions. Skin drinks up the lightweight formula immediately so you can layer on your favorite moisturizer and makeup without having to worry about pilling. The oil-free formula is a godsend for those who suffer from oily skin or frequent breakouts.

While most vitamin C face serums are applied in the morning (to protect skin throughout the day), this formula is best used at night. Containing a higher concentration of vitamin C than many other products -- 18 percent to be exact --this serum helps build collagen while you sleep while also repairing the skin from the damaging exposure it received during the day.

If fine lines and discoloration are messing with your complexion, add this vitamin C serum to your skin-care arsenal. InstaNatural Vitamin C Serum uses both hyaluronic acid and vitamin C to dually fight wrinkles and age spots in order to improve skin's overall tone and texture.

Patented Japanese seaweed encapsulation technology protects the vitamin C in this serum from exposure to light or oxygen -- both known to decrease efficacy --until it's applied directly to skin. Once applied, the tiny capsules burst open to drench your skin in good-for-you antioxidants. Definitely a more exciting way to apply vitamin C to your face.
