Korean Glutathione 7 Dark Spot Serum, Radiance Booster

How To Use — Korean Glutathione 7 Dark Spot Serum

Step 1: Cleanse

Start with a clean face. Use your regular cleanser to remove makeup, sunscreen, and impurities so the serum can actually absorb instead of sitting on top of residue.

Step 2: Dispense a few drops

Using the dropper, apply 2–3 drops to your fingertips or directly onto your skin. This serum is concentrated with 7 active ingredients, so a little goes a long way — you don't need to soak your whole face.

Step 3: Apply to dark spots and uneven areas

Gently press and pat (don't rub) across the areas where you see the most discoloration — sun spots, post-acne marks, or overall uneven tone. Work outward until fully absorbed.

Step 4: Let it set before layering

Give it 30–60 seconds to fully sink in before applying the rest of your routine. This helps the actives actually penetrate instead of getting diluted by whatever goes on next.

Step 5: Follow with moisturizer and SPF

Seal it in with your regular moisturizer, and always finish your morning routine with SPF — sun protection is what keeps new dark spots from forming while this treats the ones you already have.

For best results: use every morning and night, consistently, for at least 2–4 weeks before judging your results.

Key Ingredients — Korean Glutathione 7 Dark Spot Serum

Glutathione — A master antioxidant that fights the free radical damage behind dark spots and dull, uneven tone, working as the anchor ingredient this formula is named after.

Tranexamic Acid (TXA) — The same active dermatologists use for melasma and stubborn discoloration, interrupting pigment production at the source instead of just fading what's already there.

Niacinamide + NAG (N-Acetyl Glucosamine) — This duo works together to block pigment transfer to the skin's surface, stopping new dark spots before they fully form while also strengthening your skin barrier.

Arbutin + Alpha-Arbutin — Natural tyrosinase inhibitors that slow down new pigment formation, giving you a brightening effect without the irritation risk of harsher ingredients.

Kojic Acid — A classic, well-studied brightening acid that targets existing dark spots directly, often used in professional-strength brightening treatments.

Vitamin C (Ascorbic Acid) — Rounds out the formula with antioxidant protection and an extra radiance boost, giving skin a brighter, more even-looking finish.

Seven actives, one serum — most dark spot products pick one or two of these. This one stacks all seven, which is why it works where a single-ingredient brightener often falls short.

Frequently Asked Questions

Everything you need to know about the Korean Glutathione 7 Dark Spot Serum.

How quickly will I see results?

Most people notice their skin looking brighter and more even within the first week of consistent use — that's 7 brightening actives working together instead of relying on just one. Visible fading of stubborn dark spots typically builds over 2–4 weeks with twice-daily use.

Is this really as effective as a laser treatment?

We can't claim it replaces a professional procedure, but tranexamic acid, kojic acid, and arbutin are the same categories of actives used in professional and prescription-strength dark spot treatments — just delivered daily instead of in a single, expensive session.

No appointments. No downtime. No sun sensitivity afterward. Just visibly brighter, more even skin.

What makes this different from a single-ingredient brightening serum?

Most brightening serums rely on one active — just vitamin C, or just niacinamide. This formula stacks seven: Glutathione, Niacinamide, NAG, TXA, Arbutin, Alpha-Arbutin, and Kojic Acid, each targeting pigment through a slightly different pathway. That's why it can succeed where a single-ingredient serum stalls out.

Which skin concerns does it target?

Dark spots, post-acne marks, sun damage, and overall uneven tone — the concerns that show up after breakouts, sun exposure, or general skin aging.

Can I use this with my current skincare routine?

Yes. Apply after cleansing and before moisturizer or SPF. The lightweight, fast-absorbing texture layers seamlessly without pilling, whether you're using it in the morning or at night.

Is this suitable for sensitive or acne-prone skin?

Yes. The formula is non-comedogenic and gentle enough for daily use, including on skin prone to breakouts and post-acne marks.

How long does one bottle last?

Used twice daily at 2–3 drops per application, one 30ml bottle typically lasts 30–45 days.

What if it doesn't work for me?

We offer a 60-day money-back guarantee — no questions asked.
