numbuzin Icy Soothing Sheet Mask

Ingredient analysis and how the ad lines read

Read on 2026-09-27

What is this product?

numbuzin No.4 Icy Soothing Sheet Mask is a cooling, soothing sheet mask sold in boxes of five 27 g sheets, with a sheet the brand says is made with mugwort powder. Its 36 entry essence is water based with glycols, sixteen plant extracts led by tea tree leaf, panthenol, adenosine with no functional filing, and a cooling agent at thirtieth. It carries tea tree leaf oil as its one essential oil, no fragrance entry, no alcohol-named entry and no fixed oil, and its one acid-named entry of 36 is hydrolyzed hyaluronic acid, so there is no exfoliating acid. The brand's skin temperature chart does not reproduce its own printed values.

What makes it different?

Pairs a named cooling agent with tea tree leaf extract and oil in an oil free essence on a mugwort-flecked sheet, where the brand's landed gauze mask is a centella and niacinamide formula with no cooling agent or essential oil. The trade off is that the skin temperature figures it leads with come from a chart whose bars and labels do not agree.
