The numbuzin No. 3 Tingle-Pore Softening Sheet Mask is one of the most talked-about products in the Korean “glass skin” routine. It is specifically formulated to tackle two of the most stubborn skin concerns: texture and enlarged pores.

What sets this mask apart is its “Tingle-Pore” sensation—a brief, prickly feeling that indicates the active ingredients are working to refine and tighten the skin.

Detailed Product Description

The “Texture-Changing” Formula

The core of this mask is a heavy concentration of fermented ingredients, which are legendary in K-Beauty for their ability to soften the skin’s surface and improve its “natural energy.”

• 20% Bifida Ferment Lysate: A probiotic that strengthens the skin barrier and increases resilience against environmental stressors.

• 9% Galactomyces Ferment Filtrate: A yeast extract that brightens dull tone, controls sebum, and smooths out bumpy texture.

The Tingle-Pore Complex™

The “tingle” comes from a botanical blend including Peppermint Leaf Extract, Green Tea, and Rosemary Oil. These ingredients act as natural astringents to “shrink” the appearance of pores and provide a refreshing, cooling finish.

The Sheet & Essence

Unlike watery sheet masks, this one features a dense, viscous essence that feels like a concentrated serum. The sheet itself is made of a thin, high-adhesion fiber that mimics a “second skin,” ensuring the nutrients are pushed deep into the pores rather than evaporating.

Important Considerations

• The Sensation: The tingling sensation is normal. However, if the tingling turns into an intense burning or persistent redness, your skin barrier may be too sensitive for daily use of this specific formula.

• The “Stickiness”: Because the essence is very nutrient-rich, it can leave a slightly tacky finish. If using it daily, it is often best as a night mask so the nutrients can fully absorb while you sleep.

• Sun Sensitivity: While not an acid-heavy mask, the refinement of skin texture always makes the skin more receptive to the sun. Always pair your morning routine with a high-quality SPF.
