The Brightening Science Behind VOUX™ Purple Ampoule

Purple has become the go-to for anyone chasing hydration and a brighter, more even-looking glow. Here's what's actually doing the work.

Tranexamic Acid

Tranexamic acid is a clinically studied brightening active that helps target the look of uneven tone and discoloration. It's become a staple in Korean brightening formulas because it tends to be well tolerated even alongside other actives, making it easier to build a routine around. For a closer look at this ingredient, see What Is Tranexamic Acid?

Niacinamide

Niacinamide (Vitamin B3) is one of the most well-studied ingredients in skincare, known for supporting the skin barrier and helping even out the look of skin tone. It shows up across all three VOUX ampoules, but in Purple it's paired specifically with brightening actives to support a clearer, more radiant-looking complexion.

Multi-Molecular Hyaluronic Acid

Rather than a single hyaluronic acid molecule size, Purple uses a multi-molecular weight system: different sizes of hyaluronic acid that hydrate at different layers of the skin. That's what gives Purple its dewy, plumped finish rather than surface-level moisture that fades quickly. For a full breakdown of why formulas combine multiple molecular weights, see What Is Multi-Molecular Hyaluronic Acid?

Glutathione

Glutathione is an antioxidant known in Korean skincare for supporting a brighter, more even-looking glow. It's a quieter ingredient compared to tranexamic acid or niacinamide, but it rounds out Purple's brightening profile.

Licorice Root Extract

A traditional botanical used in Korean skincare for supporting a more even, luminous-looking complexion. It's a gentle addition that complements the other brightening actives without adding any harshness to the formula.

Who Purple Is Best For

Purple is designed for skin that feels dry, dull, or depleted, and for anyone wanting enhanced hydration alongside a brighter, more radiant look. It's typically used in the morning, layered under moisturizer and SPF, though it can be used any time skin needs a hydration boost.
