Facetheory tranexamic acid: what to know

Tranexamic acid can be included in skincare routines for dark marks and melasma, where pigment becomes more noticeable in patches. It is not a bleaching agent and does not remove pigment instantly. A product's full formula may contain other active ingredients, so the label matters when considering irritation or interactions with the rest of your routine. Pigmentation can return or deepen with sun exposure, hormonal changes or skin inflammation.

Patch-test according to the product directions and introduce it gradually rather than adding several new actives at once. Apply it only as directed, keep it away from eyes and broken skin, and use broad-spectrum sunscreen during the day. Stop if you develop marked burning, swelling, blistering or a spreading rash. A dermatologist can help distinguish melasma from other causes of darkening and suggest a plan. For clinical context, see Tranexamic Acid and Tranexamic Acid for Melasma.

Seek medical advice for sudden pigment changes, a changing or bleeding spot, persistent inflammation, or a reaction that does not settle after stopping the product. Ask before use if you are pregnant, breastfeeding, have sensitive skin, or use prescription treatments. Topical skincare is different from tranexamic acid prescribed for heavy bleeding; do not substitute one for the other.

Is this pigmentation consistent with melasma? Does the full ingredient list fit my current routine? How should I manage irritation? Would a prescription option be more suitable?
