Activated oxygen skincare

Four ingredients. One delicate area. The lightweight serum you reach for morning and night.

Kōzōn Zephyr is a gentle, hydrating eye serum built on just four pure ingredients and activated oxygen (O₃). It glides on with the rollerball, absorbs without heaviness, and leaves the under-eye area looking refreshed, luminous, and well-cared-for.

What it does

  • Delivers lightweight hydration to the delicate under-eye area†
  • Helps the under-eye area look brighter, more awake, and well-rested†
  • Pairs organic rosehip and apricot oils — both long valued in botanical skincare — with carrot seed and chamomile for a featherlight finish
  • Glides on with the rollerball and absorbs without a greasy residue
  • For the look of smoother, more radiant under-eyes†

When people reach for Zephyr

Many in our community make Zephyr a small morning-and-night ritual — a few rolls under each eye before the day starts and again at wind-down. It layers cleanly under the rest of your routine.

What's in it

A short, intentional ingredient list — nothing added to fill space on a label.

  • Organic rosehip oil (Rosa rubiginosa) — a botanical oil long valued in skincare for its light, nourishing feel.
  • Apricot kernel oil (Prunus armeniaca) — a soft, fast-absorbing oil that carries the formula.
  • Activated oxygen (O₃) — the signature Kōzōn ozonation, infused into the plant oils under controlled conditions.
  • Carrot seed essential oil (Daucus carota) — for a subtle botanical character.
  • Chamomile essential oil (Anthemis nobilis) — gentle and skincare-grade.

INCI: Rosa Rubiginosa Seed Oil, Prunus Armeniaca (Apricot) Kernel Oil, Ozone, Daucus Carota Sativa Seed Oil, Anthemis Nobilis Flower Oil.

About the ingredients

Rosehip and apricot oils have a long tradition in botanical skincare, prized for their light texture on delicate skin. Kōzōn infuses them with activated oxygen (O₃) — the ingredient at the heart of every formula — and keeps the list short so it's easy to see exactly what's going near your eyes.

How to use

Gently roll the serum under each eye, then use fingertips to pat and massage it in. Use morning and night, or as needed. For external use only — avoid direct contact with the eyes.

Good to know

  • External use only. Avoid direct contact with the eyes.
  • No synthetic fragrances, parabens, sulphates, or fillers.
  • Patch test on the inner forearm 24 hours before first use if you have sensitive skin.
  • Packaged in glass.

Great for Sensitive Skin

Most eye serums really irritate my skin because it is so sensitive. This is the only eye serum I use because it is so gentle while still refreshing my skin like an eye serum is supposed to!

I first used Kozon a couple years ago. I keep ordering it, love it and don't even want to try anything else.

Use it Every Day and Love it!

I use the Zephyr Eye Serum every day. I think it helps with the puffiness and the wrinkles. I definitely like the glow it gives me.
