Tranexamic Acid: the one-stop shop for treating pigmentation and dark spots, brightening the skin with unprecedented efficacy. It is a powerful ingredient recognized for its ability to brighten skin complexion and improve the appearance of discoloration. Unlike many acids of the likes of exfoliating lactic and glycolic, this one is safe for all skin types, complexions, and use during pregnancy. In fact, tranexamic acid is less irritating than most dark spot-diminishing ingredients. Unlike controversial hydroquinone, it does not come with the risk of "ochronosis, a rare paradoxical pigmentation of the skin." Due to this risk, there are limitations in how long you can use hydroquinone. Tranexamic acid, on the other hand, has no limits. Plus, tranexamic acid can treat existing pigmentation effectively and products containing the ingredient are recommended for preventing post-inflammatory pigmentation (PIH). In addition, transexamic acid does not make skin more sensitive to sun. In fact, tranexamic acid decreases the skinís sensitivity to UV. In short, transexamic acid is heaven-sent for anyone dealing with melasma, hyperpigmentation, acne scarring, or purple-y red-splotched complexions.
