Some skincare products do one thing well. The Nature's Greatest Secret Colloidal Silver 20ppm range does something different — it gives you the same minimalist, naturally derived formula in every size and format you could need, from a pocket-sized travel spray to a 300ml refill bottle that keeps the whole system going.
Two ingredients. Purified water and silver. That's it.
Here's why that simplicity, combined with genuine format versatility, makes this one of the most practical ranges in everyday skincare.
What Is 20ppm Colloidal Silver?
20ppm refers to parts per million — the concentration of silver particles suspended in purified water. It's a lighter concentration than the 80% True Amber Colloidal Silver range, making it well suited to everyday routine use on the face, body, and hands.
The formula is preservative-free, alcohol-free, and fragrance-free — nothing added, nothing unnecessary. Just a clean, stable silver solution in purified water, produced in Nature's Greatest Secret's East Sussex facility using 99.99% pure silver.
The Range — One Formula, Every Format
20ml Pocket Spray — The One That Goes Everywhere
The smallest in the range and arguably the most useful day to day. At 20ml it fits in a jacket pocket, a handbag, a gym bag, or a carry-on — airline-approved and always to hand.
A quick mist on the face after a commute, on hands after a long day, or over skin after outdoor activity keeps things feeling fresh wherever you are. One product, no fuss, takes up almost no space.
100ml Spray — The Everyday Essential
The mid-size spray is the format most people reach for at home. Fine mist application over the face, neck, or body as part of a morning or evening routine — or throughout the day whenever skin needs a refresh.
The 100ml size sits neatly on a bathroom shelf or dressing table and lasts well with daily use. The amber glass bottle protects the solution from light exposure to keep it stable.
100ml Dropper — For Precise, Targeted Application
The dropper format gives you complete control over where and how much you apply — ideal for targeted areas, for layering under other products, or for anyone who prefers a more measured application.
Particularly popular for facial routines where a fine mist might feel too broad, or for applying to specific areas of the body with precision.
300ml Refill Bottle — The Sustainable Choice
The 300ml format is the practical backbone of the range. Designed to top up your spray or dropper bottles as needed, it makes the whole system more cost-effective and significantly reduces packaging waste.
For anyone who uses colloidal silver as a daily skincare staple — and many people do — the refill format means you never run out unexpectedly and you're not constantly buying new bottles. It's a simple, low-waste approach that makes sense for regular users and conscious households alike.
How People Use the 20ppm Range
The two-ingredient formula means it works across a surprising range of everyday situations:
Daily facial mist Mist over clean skin morning and evening as a toner step, or throughout the day as a mid-afternoon refresh. Fast-absorbing and leaves no residue.
After outdoor activity After a walk, run, cycle, or time spent in the garden — a light mist over the face and hands keeps skin feeling fresh without needing a full cleanse.
Travel companion The 20ml pocket spray fits airline liquid rules without decanting. The 100ml spray is ideal for hotel bathrooms. The 300ml refill stays at home ready for when you return.
Post-gym freshening A quick mist after exercise keeps skin feeling comfortable before a shower is possible.
Layering in a skincare routine Applied before a moisturiser or serum, the lightweight solution absorbs quickly and layers easily under other products without interference.
The whole family The gentle, fragrance-free formula is suitable for all skin types including sensitive skin, making it practical for the whole household.
Why the Refill System Makes Sense
The 300ml refill bottle deserves a special mention for anyone thinking about reducing the environmental footprint of their skincare routine.
Rather than buying a new 100ml spray every time, you buy the refill once and top up. The amber glass spray and dropper bottles are durable and designed to be used repeatedly — they're not disposable by design.
Over time this means less packaging, less waste, and better value. For a product used daily, that adds up quickly.
The Simple Version
If you've never tried colloidal silver as a daily skincare step, the 20ppm range is the most accessible place to start. The formula couldn't be simpler, the formats cover every situation from gym bag to bathroom shelf to holiday luggage, and the refill system means it's genuinely practical for long-term daily use.
Start with the 100ml spray for your bathroom routine, add the 20ml pocket spray for on the go, and pick up the 300ml refill when you're ready to commit to it as a daily staple.
Two ingredients. Every format. One very versatile routine.
