Tranexamic acid (also known as TXA) is synthetically derived from an amino acid called lysine. Unlike alpha and beta hydroxy acids, TXA is not an exfoliating acid. If hyperpigmentation and redness are ongoing battles for your skin, 2-3% Tranexamic Acid might be the perfect one for you! 

a. Skin-Brightening Properties 

TXA works by inhibiting the transfer of pigment to the skin surface. It specifically works on pigmentation which is great if you are struggling with the look of post-breakout marks of any colour or uneven skin tone. However, TXA alone may not be effective enough on its own since it works even better as an ensemble when paired with other brightening actives like vitamin C, alpha arbutin and niacinamide. Combining a blend of these actives also helps to ensure better results as each has unique mechanisms of targeting pigmentation. 

b. Reduce Redness and Inflammation 

TXA also exhibits anti-inflammatory properties to calm and soothe inflamed skin. Interestingly, it also helps to restore the skin barrier. Since tranexamic acid acts on blood vessels as well, it has the potential to reduce post-inflammatory erythema (PIE). If you are constantly struggling with redness and rosacea, this is definitely worth a try!

All in all, if you are looking for an effective brightening serum, make sure to find one with this powerful combination of actives. And just like any other skin brighteners, it is important for you to wear your sunscreen in the morning!
