SOME BY MI - Galactomyces Glutathione Glow Serum Mask Sheet 22g x 10ea

SOME BY MI Galactomyces Glutathione Glow Serum Mask soaks each sheet in 22g of serum-grade essence — the treatment-strength counterpart to the brand’s daily mask, ten sheets per box.

A serum on a sheet

The “serum mask” label means the essence is concentrated like a leave-on serum rather than diluted like a toner — 22g per sheet is a generous soak, and the reason one wear leaves visibly more behind than a daily mask does.

Galactomyces for refinement

The fermentation filtrate that built the reputation of Asia’s first-essences — associated with smoother texture and a clearer, more even look. Ferments are radiance ingredients with decades of history behind them.

Glutathione for tone

Korea’s established brightening antioxidant, at treatment-mask strength here rather than daily-mask gentleness.

The 0.00 formula, vegan sheet

Free of 26 recognized irritants, EVE vegan certified, biodegradable sheet, irritation testing completed — a treatment mask engineered to stay comfortable on reactive skin.

Honest framing on masks

One mask brightens how skin looks for a day or two — the perfect before-an-event move. Lasting tone change belongs to daily serums and sunscreen. Both have their job.

How to use

After cleansing and toner, apply the mask and smooth to fit. Leave for 10–15 minutes, remove while still damp, and pat the abundant remaining essence into face and neck. Follow with moisturizer. Use two to three times a week.

Frequently asked questions

How is this different from the Daily Mask?

Same ingredient story, higher concentration and a heavier essence load — this is the weekly treatment; the Daily Mask is the everyday habit.

Can I use it daily anyway?

Two to three times a week is the sensible rhythm at this strength.

What do I do with the leftover essence?

Pat it into neck, chest and the backs of hands — the areas that show tone changes first and get skincare last.

Is it suitable for sensitive skin?

The 0.00 formula and completed irritation testing are built for it. Patch test if your skin is very reactive.

Do I rinse after?

No — pat in and seal with moisturizer.
