Tranexamic Acid

Tranexamic acid is a well-researched brightening ingredient that helps reduce the visible appearance of stubborn dark spots and post-blemish marks. It supports a more even, balanced-looking skin tone with consistent use.

• Helps reduce the appearance of stubborn dark spots and post-blemish marks
• Supports a more even, balanced-looking skin tone over time
• Well-tolerated across a range of skin types and tones

• Morning or evening — tranexamic acid suits either, and both if you like.
• After cleansing, on clean dry skin, before moisturizer.
• Across the whole face rather than dabbed on individual spots — the areas around a mark tend to even out too. Keep it out of your eyes.
• Every day from the start is fine. There is no easing-in period and no settling-in phase to wait out.
• If anything shows up at all it is usually mild redness, dryness or a little flaking in the first few days. It settles on its own — moisturize over the top and carry on.
• Give it time — you may notice a difference from around the second week, and it keeps building over a couple of months.
• Wear sunscreen daily. Sun exposure is what drives the pigment you are working on, so it is what keeps the results visible.
• It is unusually easy-going alongside other actives, so it does not need an evening of its own.
• Patch test first if you react easily to new products, and stop using it if irritation persists.

Discontinue use if persistent irritation occurs.

Fragile or Sensitive — Use it less often — or stop — if it feels uncomfortable, and keep it off skin that’s broken, cut or sunburned.

Dry or Itchy Patches — Keep the rest of your routine well moisturized, and use it less often — or stop — if you notice tightness or itching.

No cosmetic regulator in these four markets sets a maximum strength for tranexamic acid. That is a limit on the rules, not a signal to use more: how much goes into a product is the formulator's decision. Some products containing this ingredient at higher strengths are prescription medicines, not cosmetics.
