A refill is your favourite LAST formula in our standard full-size biophotonic glass bottle - same trusted product, same potency - but with a simple screw cap instead of a pump. You transfer your existing pump and shou sugi ban wooden cap from your previous bottle, and you're good to go. No waste. No compromise.

All five LAST products (and Sets!) can be ordered as refills: Skin Repair Serum, PHA Exfoliating Toner, Fundamental Serum, Moisturising Essence and Cleansing Gel. To order, simply select the "Refill" option on the individual product page.

Yes - completely identical. A refill contains the exact same formula, the same full size and is packaged in the same biophotonic violet glass that protects the ingredients from degrading light. The only difference is the cap.

Our biophotonic violet glass blocks the full spectrum of visible light while allowing beneficial UV-A and infrared light to pass through. This preserves the bioactivity of our plant extracts and active ingredients far longer than standard clear or dark glass. It's not about just being beautiful, but functional.

Simply unscrew the pump from your finished bottle and screw it onto the refill. The wooden shou sugi ban cap lifts off and on. No tools, no fuss - it takes about seven seconds.

The biophotonic glass bottle is recyclable. We encourage you to clean it and bring it to your local glass recycling facility. If you're in Warsaw and would like to return it to us directly, reach out - we're always exploring ways to close the loop.

We considered it - and chose not to. Topping up an already-used bottle creates a real microbiological risk: no matter how carefully you rinse and dry your old bottle, it's virtually impossible to fully clean and perfectly dry the interior. Any residual moisture or organic matter becomes a breeding ground for microbial contamination - which would compromise both the integrity of the formula and, more importantly, the safety of your skin. A fresh, sealed bottle is the only way we can guarantee the product reaches you exactly as it was made.

Not yet - but it's something we're working on. In the meantime, simply reorder through the product page whenever you're running low. We recommend ordering before your current bottle is completely empty, so your routine never has to pause.

You asked for them - so we listened. Many of you reached out, heartbroken at the thought of throwing away that beautiful shou sugi ban wooden cap after just one use. We felt the same way. The refill system is our answer: a way to keep the ritual going, reduce unnecessary waste, and make sure that something made with this much care gets to live more than one life.
