Tranexamic Acid 6% (TXA) Serum with Niacinamide & Glutathione

Sound familiar?

Dark marks don't linger because you're impatient.
They linger because the dose is timid.

Post-blemish marks that overstay, dullness that reads as “tired,” tone that never quite evens out — and a shelf of watery serums that were mostly actual water. This one is deliberately light on the skin and heavy on the label: 6% TXA in a witch-hazel botanical base.

Watery on purpose, loaded on purpose

Fade → brighten → sink in, with every active named on the label.

Why this TXA serum is different

The full breakdown

• 6% TXA, TUNED FOR THE DUO: I designed this serum and my BRIGHT124 TXA cream to work together — so 6% is the optimal dose here, not a compromise. And I made it deliberately watery: any oilier and it gets greasy and tacky, which I can't stand. Light on the skin, serious on the actives.
• I NAME EVERY ACTIVE — NOTHING HIDDEN IN A "BLEND": Tranexamic acid does the heavy lifting; I backed it with glutathione, niacinamide and turmeric root water for a clearer, more even-looking, radiant complexion. You'll find every supporting active on the label — I don't hide them behind a vague "proprietary blend."
• WATERY, NEVER WEAK — IT'S WITCH HAZEL WATER, NOT PLAIN WATER: Don't let the light texture fool you — I built the base on witch hazel botanical water, not filler water, so a high dose of actives sinks in fast and grips the skin. Watery on your finger, loaded with actives on your face. That's absorption and adhesion, exactly how I intended it.
• ALCOHOL-FREE, FRAGRANCE-FREE — I FORMULATE FOR REACTIVE SKIN: I have reactive skin, so I built this without alcohol, fragrance or artificial color, then calmed it with ayurvedic botanicals — centella, holy basil and neem — in a pH 5–6 comfort range. Zero sting, zero tack: it layers clean under moisturizer, sunscreen and makeup, morning and night.
• THE WATERY STEP 1 UNDER MY BRIGHT124 TXA CREAM: I designed this serum and my BRIGHT124 TXA cream as one routine: the watery serum sinks in first and preps the skin, then the cream layers on top to seal it in — a full tone-care duo, twice the reason. One daily step for the look of post-blemish marks, dullness and uneven texture. Korean skincare for glass skin, made in Seoul. All skin types.

From the formulator

"I made this watery on purpose — any oilier and it turns greasy, which I can't stand. But watery never means weak: the base is witch-hazel water, the TXA is 6%, and every supporting active is named on the label. It's the first half of a duo I designed to be sealed in by my BRIGHT124 cream."
