numbuzin No.4 Icy Soothing Sheet Mask — 5 Pack Cooling, Hydrating with Tea Tree & Bergamot

numbuzin No.4 Sheet Mask delivers an instant, alcohol-free cooling sensation and lightweight hydration to calm heated, irritated skin.

This Korean sheet mask is formulated to lower skin temperature quickly while supplying moisture and soothing botanical extracts. Designed for hot, stressed, or acne-prone skin, the thin mugwort-infused sheet fits close to the skin so active ingredients like Tea Tree and Bergamot Leaf extracts can work efficiently without a sticky residue. The pack contains five single-use masks for convenience and targeted cooling relief after sun exposure, exercise, or any warming event.

How fast does the mask cool and how long does the effect last?

The No.4 formula is designed for immediate sensory cooling upon application. Clinical testing shows a measurable drop in skin temperature, and the cooling sensation continues for an extended period to help relieve heat-related discomfort.

• Immediate perceptible cooling right after application.
• Cooling effect maintained for up to 30 minutes in clinical settings.
• Alcohol- and menthol-free formulation for comfort on sensitive skin.

What does the serum feel like and will it make my skin sticky?

The serum is lightweight and non-sticky, formulated to hydrate without leaving a heavy film. It balances oil and moisture so the skin feels refreshed, eased, and comfortable after removing the sheet.

• Thin, fast-absorbing essence that controls excess oil.
• Leaves a dewy but non-greasy finish suitable for daytime or evening use.
• Designed to layer under makeup or follow up with routine products.

Which active botanicals are included and what do they do for my skin?

Key botanicals in this mask are Tea Tree Extract and Bergamot Leaf Extract, supported by a mugwort-infused fabric that helps deliver calming effects. These plant-derived components are targeted to soothe irritation and support clearer-looking skin without harsh exfoliation.

• Tea Tree Extract: helps comfort acne-prone or reactive skin types.
• Bergamot Leaf Extract: provides gentle botanical calming benefits.
• Mugwort sheet: enhances close contact and even ingredient delivery.

Can I use this after sun exposure or exercise?

Yes — the mask is well suited for post-sun or post-workout recovery when the skin feels warm and sensitive. Its cooling, hydrating formula helps restore a calmer skin sensation while reducing the immediate feeling of heat.

• Ideal for cooling down after outdoor activities or heat exposure.
• Single-use sheets are convenient for travel or gym bags.
• Safe to use on irritated skin thanks to its gentle composition.
