KLAIRS - Midnight Blue Calming Sheet Mask 25ml x 10ea

The Midnight Blue Calming Sheet Mask puts the blue line’s signature relief into fifteen scheduled minutes: a dark bamboo-charcoal sheet that cools on contact, helps keep pores clean, and soaks skin in light, long-lasting hydration. Ten masks per box, because calm works better as a habit than an emergency.

Why It Works

The sheet is the visible difference — soft bamboo charcoal material that adheres comfortably to the face and supports the pore-clearing side of the brief while it cools. Inside, a light essence delivers the hydration; the temperature drop delivers the relief that heated, flustered skin recognizes immediately. Both a Primary Skin Irritation Test and a Primary Skin Irritation Test for Sensitive Skin are completed — receipts, in a category that rarely provides them.

How to Use

Fifteen to twenty minutes on clean, toned skin — chilled in the fridge for the full Midnight Blue experience — then pat in the essence and seal with cream. Reach for it after sun, after actives, or on any evening skin runs hot; it pairs natively with the Midnight Blue Calming Cream for spot rescue afterward.

Who It’s For

Reactive, easily flushed, and combination skin that wants soothing without heaviness — and anyone whose face ends summer days warmer than it started them. Neighbors in Redness & Irritated Skin and Korean Cooling Skincare.

FAQ

Is it tested for sensitive skin?

Yes — the formula completed primary skin irritation testing, including the sensitive-skin version of the test. Patch testing your first mask remains a good habit for very reactive skin.

What does the bamboo charcoal sheet do?

It gives the mask its comfortable, close adherence and supports the pore-cleansing side of the formula — charcoal’s classic role — while the essence handles cooling hydration.

Should I refrigerate sheet masks?

For this one, absolutely — cold multiplies the calming effect on heated or sun-stressed skin and turns the mask into genuine relief rather than just a step.
