This is RNW team. Thanks for your question. Tranexamic acid accounts for 0.01%. Not only Tranexamic acid but also niacinamide, ascorbyl glucoside, glutathione, tocopherol contain in this product. Which belong to different whitening mechanism. Reducing melanin multidimensionally. **Q: What % niacinamide? also, .01% tranexamic acid is nothing. most brands use 5%+. the peptides come after it on ingredient list. why bother adding them?** A: Dear Customer Thank you for your question! Our RNW DER Concentrate Niacinamide Plus has 5% of Niacinamide acid. Tranexamic acid and Niacinamide acid work pretty well together. However, the brightening mechanism is different for each of these acids. We found that it was the best balance between those two to give your skin a brightening effect without drying it out! Regarding peptides, they have anti-oxidation, anti-aging, moisturizing, and elasticity-enhancing effects. However, they can be irritants if their quantity is too important. So we took just what was needed to give you their benefits without irritating your skin! I hope it answered your question ~ Have a lovely day RNW Team **Q: Is this suitable for sensitive skin?
