Why Rosé Hour
We created Rosé Hour from a simple observation: there are countless lip products, each offering something different — color, shine, hydration, plumping, or care. We wanted to bring these elements together in one thoughtful lip ritual.
Rosé Hour combines skincare-inspired actives with a sensorial experience: peptides, multi-level hyaluronic acid, ceramides, and soothing botanicals come together to hydrate, smooth, plump, and care for the lips, with a refreshing cooling touch.
And we wanted it to be something you could reach for anytime. Before makeup, after makeup, throughout the day, or as the last step before bed — Rosé Hour is designed for 24/7 lip care, whenever you want a little moment for yourself.
The rose-gold finish was intentional, too. Soft and feminine, yet luminous and confident, it captures the spirit of Rosé Hour — a little beauty ritual that feels personal, polished, and entirely your own.
Everyone has their own Rosé Hour.
The Rose Gold Behind Rosé Hour
Rose Gold brings together two sides of CELLIN: the quiet confidence of gold and the softness of pink.
We’ve always loved pink, but never the overly girly kind. We wanted something more nuanced — feminine, warm, and confident, with a sense of individuality.
That’s where rosé comes in.
Rosé brings a little more depth to pink — softer, richer, and with a story of its own.
Inspired by the beauty of botanicals and flowers, Rose Gold brings that softness together with the richness of gold — creating a color that feels feminine, elevated, and quietly powerful.
