Tranexamic Acid
Tranexamic acid targets pigmentation from a different angle than most brightening actives — it interrupts the inflammatory signal that triggers melanin overproduction in the first place, which makes it particularly useful for pigmentation caused by inflammation or hormones rather than pure sun exposure.
How it works
A synthetic lysine analogue that blocks the binding of plasminogen to keratinocytes, effectively downregulating ultraviolet-induced arachidonic acid release. By mitigating underlying inflammatory cascades, it suppresses melanocyte activation and successfully prevents stubborn vascular melasma networks.
In practice, that's why it's often paired with a tyrosinase inhibitor like kojic acid or alpha-arbutin — one interrupts the trigger, the other blocks the pigment production itself.
How to introduce it
Wait about 5 minutes before the next step. Judging Tranexamic Acid before week 12 means judging it before it's had time to actually work — most of what reads as "this isn't doing anything" in the first couple of weeks is just too early to tell.
- Sunscreen is mandatory daily — pigmentation actives are undone by unprotected sun exposure.
- Kojic Acid specifically: do not combine with Vitamin C (Ascorbic Acid) in the same session.
Who should be careful
Tranexamic Acid's safety rating is the lowest tier tracked here — well tolerated by most skin types, including sensitive skin, without a slow introduction.

Common in these product forms
Among the products Skinzy tracks in India that contain Tranexamic Acid, it most often shows up as a serum.
Questions people ask
Interrupts the inflammatory trigger behind dark spots — especially useful for hormonal or post-inflammatory pigmentation.
Most people see a fair result around 12 weeks of consistent use — judging earlier usually means judging too soon.
Either — Tranexamic Acid works in both a morning and an evening routine.
