The patch: you clean what you can see, wiped away. The room: moisture, humidity, poor ventilation and airborne spores remain, so mould returns.

That's why cleaning can become a cycle.

Before you decide.

How does First Light work?

Two of the six oils, clove (eugenol) and Litsea Cubeba (citral), are the primary antifungals: citral disrupts ergosterol biosynthesis in the mould's cell membrane, while eugenol acts on the membrane directly. The other four carry the vapour and slow evaporation, so it keeps working in the air of the room.

How quickly should I expect results?

Fresher smell in a week. Patch behaviour takes two to four weeks of daily diffusion. That is why the refund window is 60 days.

How do I use it?

Diffuse daily in the room mould keeps showing up in. We email you our 6-page guide, Why Mould Keeps Coming Back, straight away, and the full how-to guide is here any time.

Can I use my existing diffuser?

Yes. First Light is just the oil, so it works in any diffuser you already own. No diffuser yet? The Protection Kit includes a waterless one.

Is it safe around kids and pets?

First Light is a natural essential-oil blend made for everyday home use. Use it as directed with the room ventilated, keep it out of reach of children and pets, and take extra care around cats. See our full guide to using First Light around children and pets.
