Zero-Waste Skincare: A Realistic Guide to a Lower-Waste Routine

Truly zero-waste skincare is close to impossible. Almost everything that keeps a formula clean and stable comes in a container. What you can do is cut waste a long way: use fewer products, finish them, pick packaging you can actually empty, and recycle what your local system really takes. That gets you most of the benefit without giving up skincare that works.

Below: why skincare waste is harder to fix than it looks, the waste nobody counts, what the research says about reuse and recycling, a practical routine, and an honest look at what we've done and what we haven't.

Why zero-waste skincare is harder than it looks

Recycling is the answer most of us reach for, and it does less than we'd like. The US Environmental Protection Agency puts the country's plastics recycling rate at 8.7% in 2018. Even the easiest plastic packaging does only somewhat better: about 29% of PET bottles and jars were recycled that year.

Skincare is awkward on top of that. Pumps, droppers and tubes often combine several materials, and small containers can be hard for sorting systems to handle. So "recyclable" on a label tells you what's possible, not what happens. What happens depends on where you live.

The waste nobody counts: product left in the bottle

Here's one most people never think about. A lot of skincare gets thrown away still inside its packaging.

In a 2025 study in the journal Sustainability, researchers emptied 124 cosmetic products as carefully as a conscientious person would, then weighed what was left. Pump dispensers left up to 26% of hand cream behind. Jars and airless pumps left less than 1%. Squeeze bottles of body lotion ranged from about 3% to 23%.

It's one lab's method, and your own habits will differ. But the pattern is useful. Packaging you can empty fully wastes less product, and wasted product is wasted packaging too, because you replace it sooner.

Reusable beats recyclable

If you can reuse something, that usually matters more than whether it's recyclable. A 2022 life cycle assessment in Resources, Conservation and Recycling Advances compared versions of a plastic makeup compact. A reusable design came out well ahead of simply using less plastic in a single-use one, and the authors recommended reusable packs made from single, recyclable materials.

That's one product type, a compact, not a serum or a cream, so treat it as a direction rather than a rule. The direction is clear, though: keep packaging in use for longer where you can, and recycling is the backup.

What goes down the drain

Packaging isn't the only waste. Rinse-off products used to carry plastic microbeads, tiny scrubbing particles that went through water treatment and into rivers and seas. They're now banned in rinse-off cosmetics in the US and the UK. In the US, the Microbead-Free Waters Act of 2015 ended their manufacture from July 2017. The UK ban on adding them to rinse-off products came in from January 2018.

People sometimes ask about the small blue beads in our capsule cream. They aren't microbeads or plastic. They're capsules holding the GHK-Cu, and they open as you rub the cream in. The cream is a leave-on moisturiser, not a scrub, and it contains no microplastics.

How to build a zero-waste skincare routine that still works

None of this means buying new things. Most of it is about using what you have better.

1. Cut the overlap. Two serums doing the same job means twice the packaging. If you're not sure what overlaps, our guide to whether you need both copper peptides and niacinamide is a good example of the question to ask.
2. Finish before you replace. Half-used products binned for something new are one of the easiest kinds of waste to avoid.
3. Get the last bit out. Cut tubes open, unscrew pumps to reach what's left, and scrape jars. The study above suggests there's often a lot left.
4. Buy fewer, larger containers of what you actually finish. One larger bottle is less packaging than two small ones.
5. Store products properly. A product that goes off before you finish it is waste. Our guide to GHK-Cu shelf life and storage covers heat and light.
6. Recycle deliberately. Rinse containers, separate pumps and caps if your local scheme asks, and check what it takes rather than guessing.

What koppā does, and what we haven't solved

We'd rather be specific than green. Here's what's true today.

• Three products, one peptide. A short routine is the most useful thing we can offer on waste. Our 3-step GHK-Cu routine is the whole thing.
• Larger sizes. The serum is 45 ml, against a typical 30 ml. The capsule cream is 80 g. The balm stick is 20 g, against a typical 9 g stick.
• A water-free option. The balm stick is a solid, water-free balm, so there's no pump or dropper.
• No microplastics in the capsule cream.

What we haven't solved: we don't offer refills, and the serum comes in a glass bottle with a dropper, and droppers are often among the harder parts to recycle. We'd rather say that plainly than call anything zero waste. If you want the full routine in one go, the Protocol is all three, and our guide to choosing between the serum, cream and stick helps if you only need one.

Frequently asked questions

Is zero-waste skincare actually possible?

Not completely, for most people. Nearly every product needs a container to stay clean and stable. What you can do is get close: fewer products, finished properly, in packaging that's easy to empty and that your local scheme accepts. A short routine you use to the end will usually beat a shelf of "sustainable" products you half-use.

Can you recycle skincare packaging?

Some of it. Simple bottles and jars are often accepted. Pumps, droppers, tubes and very small items are harder, because they mix materials or are too small to sort. Rinse containers, take off caps and pumps if your scheme asks, and check your local rules. A "recyclable" label means it can be recycled somewhere, not that it will be.

Do solid skincare products create less waste?

Often, yes, because they skip the pump or dropper and are easy to use to the last bit. It isn't automatic, though. A solid product you don't finish is still waste. Choose solids for jobs where they genuinely work well, such as balms for dry patches, rather than switching everything for the sake of it.

The short version

Zero-waste skincare is a direction, not a finish line. Recycling rates are low, so the bigger wins are using fewer products, finishing them, choosing packaging you can empty, reusing where you can and recycling carefully. We keep our range to three products in larger sizes, with no microplastics, and we don't offer refills yet. That's the honest version.
