Tranexamic acid was originally an oral medication but is now widely used as a topical brightening active in skincare. In VOUX™ Purple Ampoule, it's formulated at cosmetic strength to target the look of uneven tone and discoloration, separate from any medical or oral use.
Tranexamic acid was originally developed as an oral medication, and it's still used that way in some medical settings. That's separate from how it's used in skincare.

It's become a staple in Korean brightening formulas because it tends to be well tolerated alongside other actives, which makes it easier to build a routine around without much irritation.
How does tranexamic acid compare to vitamin C?
Tranexamic acid is generally gentler and more stable than Vitamin C, an antioxidant that can be irritating at higher concentrations. Both target brightening, but tranexamic acid's stability makes it a common choice in sensitive-skin-friendly formulas like VOUX™ Purple Ampoule, and the two aren't mutually exclusive.
Both are popular brightening ingredients, but they work differently and tend to feel different on skin. Vitamin C is an antioxidant that some people find can be irritating or unstable depending on the formulation, especially at higher concentrations. Tranexamic acid is generally considered gentler and more stable, which is part of why it shows up so often in sensitive-skin-friendly brightening formulas. They aren't interchangeable, but they're not mutually exclusive either; some routines use both.
Does tranexamic acid pair well with niacinamide?
Yes. Niacinamide supports the skin barrier while helping even out the look of tone, and tranexamic acid targets the look of discoloration more directly. VOUX™ Purple Ampoule pairs both actives together, along with multi-molecular Hyaluronic Acid, for hydration and visible brightening.
Yes. The two are commonly formulated together because they target the look of skin tone from slightly different angles, niacinamide supporting the skin barrier while helping even out the look of tone, tranexamic acid targeting the look of discoloration more directly. VOUX™ Purple Ampoule pairs both for this reason.
Is tranexamic acid safe for skin? Topical tranexamic acid is generally well tolerated, but as with any new active, a patch test is a good idea before applying it to your full face. If you have a specific skin condition or are pregnant or nursing, check with a dermatologist before adding any new active to your routine.
