THE COMPLETE SET: HIKARI, YORU, KINU

Mittsu, meaning three. One ritual, morning to night.

WHY TOGETHER?

Each formula does its own job, and does it properly. Together, they cover the whole day. Wagyu Tallow is the constant. Peptides by day, hyaluronic acid by night, ceramides for hands, each formula built to answer a different moment, without ever compromising on what matters most.

WHAT’S INSIDE

Hikari (Day Cream), Yoru (Night Cream) & Kinu (Hand Cream).

How to use Mittsu

Morning to night

Four steps

Hikari to start the day, Kinu whenever hands need it, Yoru to end it. Three formulas, one ritual, nothing to work out.

Morning

After cleansing, warm a pea-sized amount of Hikari between your fingertips and press it into the face and neck.

Protect

Finish with a broad-spectrum SPF. Hikari's glycolic acid gently renews the skin, which also makes it more sensitive to the sun.

Anytime

Use Kinu after washing your hands, or whenever they feel tight. It absorbs quickly, so you can get straight back to your day.

Overnight

Cleanse away the day, then press a pea-sized amount of Yoru into the skin as the last step before bed.

Made for skin

Koyu is built on a single idea: that nature has already perfected an ingredient for human skin, and it was hiding in plain sight until now.

Nature’s Finest Ingredient

For generations, Wagyu has been prized for its extraordinary lineage, distinctive marbling and the exceptional care behind its production.

KOYU takes that same reverence and applies it somewhere entirely new: skincare.

Founded from generations of farming knowledge, KOYU transforms Wagyu Tallow into fully formulated luxury skincare designed to deeply nourish, support the skin barrier and leave skin feeling softer, smoother and more resilient.

FAQs

Hikari, the day cream, Yoru, the night cream, and Kinu, the hand cream. All three full-size, together in one presentation box.

It's made to be given. Face and hands, morning to night, in a single box, so there's no guessing what they'll need.

You get all three full-size formulas for £120, which is £8 less than buying Hikari, Yoru and Kinu on their own.

Yes, during the day. Hikari contains glycolic acid, which can make skin more sensitive to the sun. Wear a broad-spectrum SPF every morning, and for a week after you stop using it.

No. All three are built on Wagyu tallow, and Yoru also contains beeswax, both animal-derived. If you avoid animal ingredients, no Koyu product will be right for you, and we'd rather say so here than let you find out later.
