Glutathione and Tranexamic Acid: Two Routes to Even Tone
Different problems, different actives
Discolouration is not one condition. Marks left after a breakout behave differently from sun-driven spots, and both behave differently from the diffuse patches that come with hormonal change. Knowing which you have decides both the active and how patient you need to be.
Glutathione is an antioxidant the body produces naturally. In skincare it works on radiance and keeps existing discolouration from deepening. Tranexamic acid does something more targeted: it interrupts one of the signals that triggers pigment production in the first place, which is why it reaches the stubborn patches exfoliation never touches.
Which one for what
Dullness and a grey undertone. Glutathione. Expect radiance rather than dramatic change, and be clear that a topical glutathione product is not lightening your natural skin colour. Anything sold on that promise is overselling what a cosmetic can do.
Stubborn patches, melasma-type pigment. Tranexamic acid. It is slow, it needs eight to twelve weeks before you can judge it, and it does not exfoliate or sting despite the word acid in its name.
Post-blemish marks. Either, paired with niacinamide. That combination is the reliable one for the red and brown marks left behind after breakouts clear.
How to build the routine
Vitamin C in the morning, under sun protection. Tranexamic acid or glutathione at night. That split lets both work without stacking irritation, and it is what most Korean tone-focused routines look like.
A gentle AHA two nights a week speeds up how quickly marked cells clear, which shortens the timeline. A retinoid does the same, more strongly, if your skin tolerates one.
The part that decides everything
Daily broad-spectrum sun protection. Without it, new pigment forms faster than the old clears and every active in the routine is working against fresh damage. This is not a caveat at the end of the article, it is the single most important variable in pigment work, and the reason most people see no result.
Realistic timelines
Post-blemish marks: six to twelve weeks. Sun spots: three to six months. Hormonal pigment: a year, and it often returns without year-round protection. If a product promised faster than that, the promise was the product.
One more thing worth knowing: if a dark spot got worse after you started treating it, the likely cause is irritation. Inflammation triggers more pigment, so an overly aggressive routine deepens the mark it was meant to clear. Slow down and calm the skin first.
