The numbuzin No.4 SOS Icy Soothing Sheet Mask (often referred to by users as the Tea Tree + Panthenol mask) is a high-performance “emergency” treatment designed to cool down stressed, heated, or acne-prone skin. It is famous for its unique “8°C cooling” claim and its herbal-infused sheet material.

Product Description

This isn’t your standard hydrating mask; it is a functional soothing treatment that targets skin “heat”—a common cause of redness, excessive oil production, and breakouts.

1. The “Icy” Cooling Technology

The mask is engineered to provide an immediate cooling sensation without the need for refrigeration (though you can chill it for extra effect). It is clinically tested to reduce skin temperature by 8°C, providing relief for over 30 minutes.

2. Unique Ground Mugwort Sheet

Unlike traditional white cotton sheets, this mask features a specialized sheet embedded with real, ground mugwort particles. This helps the mask adhere better and delivers the calming properties of mugwort directly to the skin.

3. Key Ingredient Synergy

• Tea Tree Leaf Oil & Mugwort: Work together as powerful anti-inflammatory and antibacterial agents to calm active breakouts and purify pores.

• Panthenol (Provitamin B5): Acts as a moisture magnet and barrier protector, ensuring the cooling sensation doesn’t lead to dryness.

• Centella Asiatica (Cica): Accelerates the healing of irritated or “angry” skin.

• Rosemary & Bergamot: Help regulate sebum (oil) production, leaving a fresh, matte finish.

Pro-Tips for Application

1. Don’t Toss the Pouch: There is usually a lot of essence left in the bag. Apply the extra essence to your neck and chest, or “re-wet” the mask after 10 minutes to extend the cooling effect.

2. Short Contact is Key: Keep it on for 10–20 minutes. Because it contains tea tree and cooling agents, leaving it on until it’s bone-dry can actually backfire and irritate the skin.

3. Summer Staple: Store a few in the fridge during the summer months for an “arctic” experience that instantly de-puffs the face in the morning.
