Learn how to refill your OS-01 FACE Refill Shell with this step-by-step guide, including tips to avoid common mistakes and keep your skincare routine sustainable.

Quick answer

To refill your OS-01 FACE Refill Shell, remove the empty pouch, insert a new refill pouch, and reattach the reusable pump. Keep the shell and pump for future refills to reduce waste.

Why refilling your OS-01 FACE shell matters

Refilling your OS-01 FACE Refill Shell is a simple way to extend the life of your packaging and reduce plastic waste. The shell and pump are designed to be reused, so you only replace the pouch when you run out of serum.

This approach supports both skin longevity and planet longevity, aligning with OneSkin's commitment to sustainable skincare. By keeping the shell and pump, you minimize single-use plastic and save money over time.

What you need before you start

Before you begin, make sure you have a new OS-01 FACE refill pouch. The pump and shell are reusable, so you should not need to replace them unless they are damaged. If you do need a replacement shell, you can purchase one separately.

Note that the refill pump and pouch must be purchased separately from the shell. Check your current setup to ensure you have all components before starting.

Step-by-step refill guide

Remove the empty pouch: Twist off the pump from the shell and pull out the empty pouch. Discard the pouch responsibly (check local recycling guidelines). Do not throw away the pump or shell—they are reusable.
Insert the new refill pouch: Take a new OS-01 FACE refill pouch and insert it into the shell, ensuring it sits securely at the bottom. Make sure the pouch is fully seated to avoid leaks or air bubbles.
Reattach the pump: Screw the pump back onto the shell until it is tight. Prime the pump by pressing it a few times until serum dispenses. If the pump does not dispense, check that the pouch is properly connected and the pump is not clogged.
