Does a Sleep Beauty pillow replace my cream?

No. It comes after you finish applying. Skincare you apply and skincare you sleep on are not rivals — they come in order.

How was SOOMGYEOL SHIM checked?

Breath Capsule technology (capsules holding carotenoids) is applied to the cover fabric your face touches. An 8-week human application test with fabric using this technology (women aged 25–45 · Dermatest) showed wrinkle depth −9.20% and skin antioxidant index +7.79%. The certified lab antioxidant test result is Grade 3, the highest grade. Figures are fabric test results and may vary from person to person.

Can I use my own pillowcase over it?

In a fabric pass-through test — one layer of ordinary pillowcase fabric, rubbed for 1 minute, then 24 hours at 37°C — the ingredients inside the capsules passed through that fabric.

What is a Sleep Beauty pillow? — Skincare you sleep on, for all 8 hours of sleep

Published 2026-10-21 · Updated 2026-10-23 · Sleep Beauty brand, SOOMGYEOL

Short answerA Sleep Beauty pillow carries skin-focused technology in the fabric your face rests on, turning the 8 hours after your night routine ends into time for care. Nothing to apply. It is there for all 8 hours of sleep.

Why a pillow

At 8 hours of sleep a night, your face rests on a pillow for about 2,920 hours a year.
Skincare ends the moment you finish applying it. The pillow stays with your face until morning.
A Sleep Beauty pillow extends the last step of the night routine — past your skincare products, to the place your face rests.

What is different — skincare you apply vs. skincare you sleep on

Skincare you apply: Creams, sleeping masks. Applied before bed, and done.
Skincare you sleep on: Nothing to apply. While you sleep, the fabric your face rests on becomes the place for care.
They do not compete — they come in order. A Sleep Beauty pillow comes after you have finished applying.

Was that fabric tested on human skin — are the duration, participants and testing lab disclosed?
