01 · The buyer decision
A 10-minute cooling mask designed around sensitive skin
Strong UV and friction, heat after a workout, harsh skincare: the moments when sensitive skin suddenly turns red happen every day. Dear Klairs Blue Calming Sheet Mask is the renewed blue mask built for exactly those moments, pairing a smooth, low-irritation sheet with a cooling, calming essence.[1]
The use is quick: only 10 minutes. In that time it cools heated skin, calms redness and reduces facial puffiness, so shoppers with easily flushed, heat-prone skin get visible relief before they leave the house.[1]
02 · Proof
Measured on five everyday irritations, cooling and puffiness
ProbeM Skin Clinical Research Center tested the mask on 20 subjects aged 20 to 39 in March 2026. Ten minutes after use, redness calmed by 55% after physical irritation, 53.8% after exercise, 52.9% after heat, 23.3% after chemical irritation and 20.9% after UV exposure. Skin temperature heated by heat stimulation dropped by 6.7°C.[1]
A second test on 20 subjects aged 20 to 60 (March to April 2026) found facial (cheek) puffiness after heat stimulation reduced by 29.5% ten minutes after use. In the same panel, 100% agreed that redness and heat felt calmed within 10 minutes, that the essence stayed moist without drying out, that the sheet felt comfortable on sensitive skin and that makeup went on better afterwards.[1]
It completed a primary skin irritation test and a primary skin irritation test for sensitive skin (30 subjects each, April 2026), with a skin irritation index of 0.00, and the formula is fragrance free.[1]
