Frequently asked questions

Can I use MEDICUBE Glutathione Glow Serum without Booster-H?

Yes. The serum works as a normal leave-on step after toner and before moisturizer. MEDICUBE publishes standalone serum results as well as separate results from pairing it with Booster-H. Use the device only if you already own it and follow its operating instructions; the serum does not require a device to be used.

Where does the serum go in my routine?

Apply it after cleansing and toner, then follow with moisturizer. If you use a thinner watery essence, apply that first; heavier creams and facial oils come later. Pat a small amount over the face and neck rather than rubbing repeatedly. In the morning, let each layer settle before sunscreen and makeup.

Can I use it morning and evening?

MEDICUBE positions it as gentle enough for daily use, and it can fit either a morning or evening routine. Start once daily when introducing it, especially if you already use several tone-focused products. Increase only if the complete formula stays comfortable. Daytime use always finishes with broad-spectrum sunscreen; this serum has no SPF role.

What does Glutathione Liposome 5% mean compared with 500ppm?

The bottle's 5% statement names MEDICUBE's marketed Glutathione Liposome complex. The official ordered formula separately lists Glutathione(500ppm). Those declarations are not interchangeable, so 5% should not be read as 5% pure glutathione. This page keeps both labels in their original context and does not convert one into the other.

How quickly were the visible results measured?

MEDICUBE reports serum-alone measurements after four weeks. Its paired Booster-H table reports glow and line-appearance measurements after four weeks, plus blemish, melanin and rough-texture measurements immediately after four uses. Those are study schedules and group outcomes, not a guaranteed personal timeline. Check each Real Result for its exact use condition.

Will the Glutathione Glow Serum feel sticky on oily skin?

It is more viscous than a watery essence because MEDICUBE designed it to provide slip for optional device use. Many shoppers describe easy absorption, while some report stickiness or an oily feel. Begin with a small amount, let it settle before the next layer and avoid adding extra simply to keep the device moving.

Is it fragrance-free or suitable for sensitive skin?

No fragrance-free claim is made here because the current ingredient list includes Flavor. MEDICUBE reports a primary patch test, but that does not guarantee comfort for every person or every sensitivity. Patch test first, introduce the serum without several other new products and stop if persistent burning, swelling, itching or redness develops.

Why is this bottle 30g when MEDICUBE now shows 50ml?

This listing is for the 30g / 1.05 oz brown bottle shown in the gallery and stored in the published variant. MEDICUBE's current direct page now shows a 50ml package under the same product name. Packaging and formulas can change between production runs, so compare the ingredient list on your own bottle when batch-specific details matter.
