take the heat off.

one piece. no bowl. no mess.

sunglasses indoors. it's her house.

oily on top. thirsty underneath. and hot in a way you stopped noticing. the matcha cold-plunge mask takes the heat off and puts the water back. one pouch. no bowl. no mess.

first word on plunge 001. nothing else.

01the problem

it's not you. it's the heat.

45°outside
20°ac inside
youin between
the heat itself the part your spf doesn't cover

uv has a number. spf 50. heat has nothing. your whole routine was built for the sun — not for 45° at the door and 20° on the other side of it.

researchers call the part that adds up heat aging. we're not claiming to stop it — we haven't tested that. what we did test is simpler: your skin temperature, 15 minutes in.

oily on top. thirsty underneath. the ac · drains the water, so your skin makes oil

you step out of 45° into 20° of dry air, four times a day. the ac pulls the water straight out of your skin. your skin panics and pumps out oil to seal the leak.

so you're shiny by noon and tight by night. and you attack the shine — mattify, strip, exfoliate — which takes even more water out. you're not oily. you're thirsty.

so you added something. then something else. it got worse. you can't add your way out of heat. your skin doesn't need more products — it needs less heat, and more water.

02what it does

less heat. more water. one pouch.

no tingle. no sting. nothing that talks to a nerve. we didn't add a sensation. we took heat away.

A

the pouch

the part you handle
  1. add water the dose is already inside. nothing to measure.
  2. shake it mixed in the pouch. no bowl, no spatula, no brush.
  3. peel it off sets into a cool rubber layer, lifts in one piece.

the powder never leaves the pouch. so the mess never happens.

B

inside the pouch

the part that does the work
  • cooling polyols 5% vs. the heat

    erythritol and xylitol dissolve in the pouch — and take heat off the surface as they go.

  • alginate film vs. the ac

    the powder sets into a rubber film. for 15 minutes, nothing evaporates.

  • matcha & chlorella whole leaves, milled

    not watered down into an extract. this green comes out of the powder.

03the spirit

kasanok seoul, peeled back.

the name

kasanok means home. casa — house — and 옥, as in hanok: the korean house. two languages, one feeling. home translates everywhere, and seoul is where we make it. and yes, we're korean.

because home is the one place you walk in and peel the day off. your shoes. your makeup. your outside face. all of it.

that's the whole idea. we're the peeler club — the people who peel off the pressure, the "shoulds," and come back to themselves. kasanok is the home. peeling off is how you get there. 🏠

why i started

adding more became way too normal. women add more, do more, buy more — then blame themselves when they still don't feel like themselves. (it was never their fault.)

more serums didn't help. more steps felt wrong. "just add one more" was the lie everyone agreed to. someone had to say it out loud.

what we're against

beauty has an addition problem. it's treated like something you build — more layers, more steps, more glow. nope. beauty isn't built.

adding is not the answer. peeling off is. and cooling is how you peel the day off.

tired women don't need more products. they need less heat. take the heat off. 🧊🍵
