Tranexamic acid is an ingredient increasingly found in skincare products designed to address uneven pigmentation and dark spots.
Topically, it can influence biological pathways associated with excess pigmentation. For this reason, it is used in some formulations targeting concerns such as post-inflammatory discoloration and melasma.
Improvement in pigmentation generally takes time and consistent use.
Because persistent or changing pigmentation can have different causes, significant pigmentation concerns should be evaluated by a dermatologist rather than relying entirely on cosmetic products.
