Centellian24 - Glutathione Toning Ampoule 30ml

Centellian24 Glutathione Toning Ampoule is one of the most concentrated formulas in the category — a 200,000ppm glutathione toning complex backed by tranexamic acid, niacinamide, melatonin and milk exosomes.

200,000ppm — what that means

Ppm is parts per million, so the glutathione toning complex makes up 20% of the formula. Honest framing: that’s the complex, not pure glutathione — but it puts the tone actives at the center of the bottle rather than the end of the ingredient list.

How glutathione works on tone

It’s an antioxidant that inhibits melanin production — excess melanin is what shows up as hyperpigmentation and uneven tone. Reducing new pigment while old pigment naturally sheds is how brightening actually happens.

10,000ppm tranexamic acid

A serious dose of one of the most respected pigmentation ingredients — originally pharmaceutical, now the go-to for stubborn dark spots and post-blemish marks.

Melatonin, vitamin C and milk exosomes

The antioxidant support cast: protection against the free-radical damage that accelerates visible aging, plus exosomes from the newest generation of renewal ingredients.

Device-compatible

The brand pairs this ampoule with its Derma Pulse microcurrent device for deeper delivery — optional, but the formula is built to work with it.

How to use

After cleansing and toning, apply an appropriate amount to face and neck and pat gently for absorption. Follow with moisturizer, and sunscreen in the morning. Use morning and evening.

Frequently asked questions

Is 200,000ppm safe for daily use?

It’s the complex concentration, formulated for twice-daily use. Introduce it gradually if your skin reacts easily, and patch test first.

What does tranexamic acid add?

It targets stubborn discoloration through a different pathway than glutathione — the two together cover more ground than either alone.

Do I need the microcurrent device?

No — the ampoule works on its own. The device is the brand’s optional upgrade for delivery.

How long until tone evens out?

Eight to twelve weeks of daily use with sunscreen — sunscreen decides whether the progress holds.

Can I use it with vitamin C?

It already contains vitamin C — layering more is fine for most skin, one new active at a time.
