About This Product
There are overnight masks. And then there is this.
Cheonyuldan — 天率丹 — translates as "the perfect ratio of heaven." It is The History of Whoo's most elevated line, reserved for skin that demands the absolute best. The Overnight Mask is its most concentrated expression — a treatment designed not merely to hydrate while you sleep, but to fundamentally regenerate.
At the heart of the formula is Dendrobium candidum Wallich ex Lindley — a rare and precious orchid that grows only above 1,000 metres elevation, where the air is thinnest and the life force is strongest. Historically treasured in Eastern medicine for centuries, it is now the cornerstone of Cheonyuldan's anti-aging philosophy: that the rarest ingredients, at meaningful concentrations, produce results that no synthetic alternative can replicate.
The formula contains 128 ingredients in total, built around HwaYul SeokGok Complex™ — Whoo's exclusive technology that significantly increases the synthesis of collagen and hyaluronic acid in the skin. Royal CheonChoHwa and 24 CheonGiBiDan herbal extracts complete the formula, keeping skin moisturised, luminous and resilient through the night.
The three transformations Cheonyuldan delivers — Hwahyeon (revived skin tone), Sooyoon (deep hydration and radiance), Seonyool (improved elasticity) — are not marketing language. They are the clinical outcomes the brand has validated and staked its most prestigious line upon.
Apply at the final step of your evening ritual. Wake up to skin that looks rested, lifted and luminous in a way that no day cream can replicate. This is what Korean women who demand the absolute best apply before they sleep.
