Sharon’s verdict
Worth it
What Sharon would tell you
Tranexamic acid interrupts pigment pathways and is particularly useful for melasma. Topical formulas often sit around 2 to 5 percent.
Oral tranexamic acid is a medical conversation, not a casual skincare add-on. For topical use, expect slow improvement and be serious about sunscreen.
