When picturing her dream skincare shelf, a product that erases dark spots and boosts brightness ranked high on Olivia Mangrum's wishlist. "The biggest thing I want to tackle with my skin is dark spots and post-acne hyperpigmentation," said the Dallas-based model who decided to put Suprême C, a NEW 100% vitamin C serum, to the test for eight weeks.

For maximum efficiency, Olivia committed to using it as her only skincare both morning and night, and took comfort in the fact that the serum’s potent-yet-gentle formula is for all skin types—even her super sensitive skin. At first swipe, she says, the springy gel-oil texture felt nourishing and melted into the skin for a bonus instant glow that not only garnered compliments from friends but lasted into the evening, too.

Thanks to the 100% THD Ascorbate refined through a multi-step process in Japan, Suprême C works with the skin's natural enzymes to absorb 3x more efficently than traditional vitamin C. But exactly how much could it even out Olivia's complexion and diminish her hyperpigmentation? Watch her skin diary to see the transformation!
