Customer experiences
In their own words.
Selected experiences with First Light and the diffuser.
Love it! Smells so good and it’s like magic, I don’t get how it works so well but it does. It has really cleared up my bathroom mould drastically.
I love the smell. I love the packaging. I love that it’s stopping mould from growing in my bathroom sink and no mould has come back on the ceiling so far. I love the diffuser as well! Great battery life, lovely and compact and looks lovely and minimal and sheek (is that how you spell that word?) Will definitely get me more when I run out.
Love the scented aroma as it wafts through rooms and the product is living up to expectations with mould management. The diffuser is a great addition to the product bundle, and I will continue to use and recommend First Light!
Just run in our diffuser
Run daily in the Aurala Naturals waterless diffuser.
6 Weeks per bottle
15ml. Diffused daily, one bottle covers roughly six weeks in a single room.
Independent Lab tested
99.2% reduction in Aspergillus niger (black mould) on direct contact. Independent lab. Test method and result available on request.
Six oils, one job
Different oils.
Complementary roles.
No single oil does the whole job. Each pair in the blend covers a different part of it, which is why the formula is six oils and not one.
Nothing else is in the bottle. No carrier, no filler, no fragrance chemicals.
Clove + Litsea Cubeba
Contain eugenol and citral. Citral disrupts ergosterol biosynthesis in the mould's cell membrane, while eugenol acts on the membrane directly. This is where the antifungal action starts.
Tea tree + eucalyptus
Contain terpinen-4-ol and 1,8-cineole. Disrupt mould cell membranes by a different mechanism.
Peppermint + cedarwood
Peppermint (menthol) adds a membrane-active antifungal action. Cedarwood (cedrol) is a natural fixative that slows evaporation so one dose lingers longer.
What people say
Reviews
Straight answers
Questions people ask about First Light.
Which diffuser should I use it with?
Any pure essential oil diffuser will run it. A waterless diffuser delivers the full lab-tested concentration because the oil is not diluted. Water-based works but at reduced strength.
How long does one bottle last?
Diffused daily in one room, a 15ml bottle lasts roughly six weeks. Less often, longer. Across multiple rooms, shorter.
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, which process some plant compounds differently to people. See our full guide to using First Light around children and pets.
Will it stain walls or fabric?
The oils are colourless as vapour. Direct drops on very absorbent surfaces (untreated plaster, raw timber) can leave a residue. In a diffuser, no staining.
How do I store it?
Cool, dark, cap on. The satin mint bottle blocks UV. Away from direct sunlight and heat. Kept sealed, it lasts two years from the bottling date.
What if it does not work?
Reply within 60 days with one photo. Refund same day. No return shipping. Keep the bottle.
Can I use it in other things (spray, cleaner)?
Diffuser use is what it is designed and tested for. Some customers add a few drops to a spray bottle for spot use on grout, but the lab-tested reduction number (99.2%) is a direct-contact figure and requires the concentration to hold.
