numbuzin No.4 Sheet Mask delivers an immediate, alcohol- and menthol-free cooling sensation while deeply hydrating and calming heated or irritated skin.
Designed in Korea for sensitive and acne-prone complexions, the numbuzin No.4 Icy Soothing Sheet Mask combines tea tree extract, bergamot leaf extract and a mugwort-infused sheet to reduce surface heat and restore comfort. The lightweight essence absorbs without stickiness, controlling excess oil as it replenishes moisture. With clinically tested cooling performance, this five-sheet pack is a practical step for after-sun care, post-workout recovery, or any time skin feels overheated.
Most users feel a cooling sensation immediately upon application because the formula is designed to lower skin temperature without using alcohol or menthol. The clinical evaluation shows continuous cooling for up to 30 minutes, offering a window of quick relief while the active extracts work on calmer skin.
Yes — the serum is formulated to feel lightweight and non-sticky while delivering lasting moisture. It helps balance excess oil and replenishes water to the surface layers, so skin feels refreshed rather than heavy or oily after removing the sheet.
The mask uses tea tree extract and bergamot leaf extract, ingredients commonly selected for their soothing properties on reactive or blemish-prone skin. The mugwort-infused sheet provides an additional calming barrier between the serum and skin, helping reduce sensations of irritation and discomfort.
Apply to clean, dry skin, smooth the sheet evenly, and leave on for the recommended time to maximize cooling and hydration. Remove and gently pat remaining essence into the skin rather than rinsing, or follow with your normal moisturizer to lock in results.
Who is this for: numbuzin No.4 Icy Soothing Sheet Mask is intended for people with heated, irritated, or sensitive skin seeking fast, non-sticky cooling and hydration. It's a good choice for anyone who needs post-sun calming, post-exercise relief, or a gentle hydrating step for acne-prone complexions. Each box contains five individually wrapped sheets for convenient, single-use care at home or on the go.
Tea Tree, Bergamot Leaf Extract, Mugwort
Q: How long should I leave the mask on?
A: Leave the mask on for the recommended time on the packaging—typically until the cooling effect diminishes, around 10–30 minutes.
Q: Is this safe for sensitive skin?
A: Formulated without alcohol or menthol and with soothing extracts, it’s designed for sensitive skin, but patch-test if you have severe sensitivities.
