Tranexamic Acid for Sun Damage (Photoaging)

Fades stubborn dark patches like melasma and deep marks left behind by acne or hormonal shifts. The one to reach for when other brighteners haven't worked.

Why it works for Sun Damage (Photoaging)

Interrupts the chain of signals that sun exposure uses to switch on pigment production, so it fades dark patches and uneven color left by the sun. The strongest evidence is in melasma and dark marks left after inflammation, which often show up alongside sun damage. At 3 to 5 percent it is well tolerated. Use at night as a brightening or maintenance step.

How Tranexamic Acid works

Plasmin inhibitor that interrupts the UV-triggered melanogenesis pathway in keratinocytes.
