Learn the correct way to refill and use the PREP Facial Cleanser Refill for a sustainable, effective daily cleanse that boosts peptide absorption.

Quick Answer

To use the PREP Facial Cleanser Refill correctly, transfer the gel into a clean, empty refillable bottle, then use a small amount daily to gently exfoliate and prime skin for better peptide absorption.

Why Refill Instead of Buying a New Bottle?

The PREP Facial Cleanser Refill cuts down on plastic waste by letting you reuse your existing pump bottle. It contains the same gentle, fragrance-free formula that boosts hydration without stripping natural oils, so you don't sacrifice performance for sustainability.

What You Need to Know Before Starting

The refill does not include a bottle. You need a clean, dry refillable bottle (the original PREP bottle works perfectly). Make sure it's completely empty and rinsed to avoid mixing old residue with the fresh gel.

How to Refill and Use PREP Facial Cleanser Refill

Prepare Your Empty Bottle: Thoroughly rinse and dry your original PREP bottle and pump. Any leftover water or old product can dilute the formula or cause bacterial growth. A dry bottle prevents contamination and keeps the preservative system effective.
Transfer the Refill Gel: Open the refill pouch and slowly squeeze the gel into the bottle. Avoid overfilling — leave a small gap at the top so the pump can draw product properly. If you fill to the brim, the pump may struggle to dispense and can push gel out of the nozzle when you first press it.
Secure the Pump and Shake Gently: Screw the pump back on tightly, then give the bottle a few gentle shakes to ensure the gel is evenly distributed. Do not shake vigorously, as that can introduce air bubbles. Air bubbles can cause sputtering when you dispense the cleanser.
Use the Correct Amount: Dispense one to two pumps into damp hands, lather, and massage onto your face for 30–60 seconds. Rinse thoroughly. Using more than two pumps wastes product and can over-cleanse. A pea-sized amount per pump is enough to gently exfoliate without stripping your skin.
Store Properly: Keep the refill pouch and the filled bottle in a cool, dry place away from direct sunlight. Heat and humidity can degrade the formula over time. Proper storage extends the shelf life and maintains the cleanser's effectiveness.
