GOYO Glutathione 7 Brightening Serum — 30 ml
Most brightening serums make you choose: results or comfort. The Glutathione 7 Brightening Serum refuses the trade — a light, milky, Korean-formulated serum that layers 7 brighteners with barrier-loving centella, squalane and deep hydration, so skin can look brighter and more even-toned without being put through a fight. Face, neck, hands. Morning and night. No sting, no peeling, no drama.
What makes it different?
If you've shopped this aisle before, you know the three doors. The prescription route that works but bites — and needs a doctor on speed dial. The "miracle" creams that promise a new face in a week. And the gentle stuff that feels lovely and does approximately nothing.
This serum is built on a different bet: brightening only works if your skin can tolerate it every single day. So instead of one harsh hero ingredient, it stacks 7 gentle brighteners — glutathione, niacinamide, tranexamic acid, arbutin, kojic acid, vitamin C, NAG — and cushions them in a barrier-first base of centella, squalane and layered hydration. Strong where it counts. Soft where it touches you.
Will it work on my skin?
Honest answer: this serum is a whole-face worker. It's made for overall dullness, uneven-looking tone, and the scatter of small spots that make skin look tired — on your face, neck, and the backs of your hands.
For the one or two deep, stubborn spots that have survived everything? That's exactly what the patches in the bundle are for: they seal the same brighteners onto the spot and hold them there for hours.
Sensitive skin: the formula is fragrance-free and non-comedogenic, with a milky texture designed for daily use. If you're reactive, patch-test first — and remember our rule: skincare should never burn or sting. If it does, stop.
How do I use it?
Step 1 — Start clean. Cleanse and pat dry, morning and night.
Step 2 — Two to three drops. Warm them between your fingertips and press — don't rub — into face and neck. The milky texture sinks in fast, no sticky film under makeup or moisturizer.
Step 3 — Don't forget your hands. The spots that give an age away rarely sit on the face. A leftover drop pressed into the backs of your hands takes ten seconds.
Step 4 — SPF, every morning. Sunlight is what deepened your spots in the first place. No brightening serum outruns an unprotected afternoon.
How does the 90-day guarantee work?
Simple: order, use the serum consistently, and give your skin the honest window this category actually needs. If within 90 days you're not happy with how your skin looks, email us and we'll refund your order in full. You don't need to send photos, return the box, or argue your case.
One thing we ask — start the routine. Our guarantee exists so you can commit without risk, not so the box can join the graveyard drawer unopened.

Frequently asked questions
General information
When will I see a difference?
We won't attach a date to your face — anyone who does is guessing. What we can tell you is how the brightening category behaves for most people:
The early weeks are about the ritual, not the mirror; gradual brightening tends to show over the following weeks; deeper, older spots take the longest.
That's exactly why our supply sizes and our guarantee are built around consistency, not miracles.
Can I use it with retinol, vitamin C or exfoliants?
Yes — it's designed to slot into an existing routine. Apply it on clean skin before heavier steps. If your routine already includes strong actives, introduce it gradually and listen to your skin.
Will it irritate sensitive skin?
It's fragrance-free, non-comedogenic, and built barrier-first — centella, squalane and layered hydration are in the formula precisely so daily use stays calm. Patch-test if you're reactive. It should never sting; if it does, stop.
Why is it milky instead of clear?
The texture carries the brighteners with skin-cushioning lipids and hydrators instead of a stripped-down alcohol base. Light, fast-absorbing, no film — and yes, it layers under makeup.
How does the bundle work?
Add the Glutathione 7 Serum Patches (60 ct) to your serum. The serum evens the look of your whole face; the patches seal an extra dose of the same brighteners onto the few spots that need more. Bundle ships free, with a mystery gift.
How does the 90-Day Honest Guarantee work?
Use the routine consistently; if you're not happy with how your skin looks within 90 days, email us for a full refund. No photos, no returns, no debate.
Where do you ship, and can I return my order?
We currently ship across the US, free on bundles. Unopened orders can be returned within 14 days; opened ones are covered by the guarantee above.
