PRE-ORDER THE PROTOCOL

The science behind the ingredient

What research informs the GHK-Cu Protocol?

The Protocol brings serum, cream and balm into one routine. Research on GHK-Cu, niacinamide and topical oils helps explain the ingredients in each step.

A shared copper peptide

All three formulas contain GHK-Cu. In lab studies, this copper peptide increased collagen production in skin cells.

Ingredients with different roles

Research on niacinamide moisturizers and topical oils informs the cream and balm ingredients. Those studies used other products.

What this means for your routine

The studies below looked at ingredients and other formulas, not the complete Koppā Protocol. They do not establish combined results or a timeline for this routine.

Why sunscreen matters. Hughes et al., 2013 — Annals of Internal Medicine. In 903 adults under 55, daily sunscreen use reduced progression of photoageing compared with discretionary use over 4.5 years.

Sarah M- I tried to to use an acid treatment to get rid of an old eyebrow tattoo and ended up with a chemical burn (oops). Once it had started to heal I began using the stick on it a few times a day. 2 days later it was so much better.

Amanda G- this is a LOT of product. I'd never heard of GHK in a stick but I'm so glad I found this one. It's great after shaving my legs. Soothing, and not messy which I love.

Jay W- I'm a pilot. The air on the plane is so dry, after a long flight I look 100 years old. This GHK cream changed everything. I never leave for work without this cream in my flight bag anymore. Plus its a big tube, but can still take it through security.
Farrah J- the cream actually has the capsules in it. I find the cream super moisturizing, not sticky.

Customer feedback on individual Koppā products.

“Been using it about 6 weeks now. Didn't notice much the first couple weeks, but my skin looks noticeably smoother around my cheeks and my makeup sits better. Will repurchase.”

Sarah M.

“I was skeptical of copper peptides after all the TikTok hype but this has earned a spot in my routine. My skin just looks more even and awake in the mornings.”

Priya K.

“obsessed. that's the review”

Olivia

“Bought it for my wife and ended up stealing it. No fragrance, which is a big plus for me. Skin feels softer after shaving.”

Marcus L.

“I have pretty sensitive skin and most serums make me red. This one hasn't caused any issues. I use it at night after cleansing and before moisturizer.”

Emily R.

“Second bottle. The fine lines under my eyes look softer, not gone, but softer, which honestly is all I wanted. Packaging is gorgeous too.”

Claire B.

“Customer service was really helpful when my order got delayed, and the product itself is great. My skin has this healthy glow now that people keep commenting on.”

Aisha N.

“Layered it under vitamin C at first and it felt like too much, switched to using them at different times of day and it's been perfect since. Smooth, bouncy skin.”

Megan F.

“I've tried so many "glow" serums that did nothing. This is the first one where I actually ran out and immediately reordered.”

PRE-ORDER THE PROTOCOL
The Protocol, explained

Three formulas. Clear benefits.

Why the complete routine earns a place in your day.

Koppā serum, capsule cream and balm stick
Why choose the complete GHK-Cu Protocol?

Three full-size formulas give you a clear, complementary routine: lightweight peptide care, cushioning daily moisture and a targeted balm for dry areas. The set makes it easy to explore the full Koppā range, and costs less than buying the three products separately.

What benefits does the Protocol focus on?

Hydration, softness, comfort and smoother-looking skin. The serum provides a lightweight first step, the cream adds moisture, and the balm lets you give dry areas extra attention. Together, they offer different textures for different needs, without adding unnecessary full-face steps.

Why use three formulas instead of just one?

Each texture has its own job. Serum layers lightly, cream provides a moisturising layer, and balm delivers focused conditioning wherever you need it. You can use one product on its own; the Protocol brings all three options together so you can adapt your routine to how your skin feels.

What makes copper peptide care worth adding?

GHK-Cu is the ingredient shared across the range and has been studied for its role in skin renewal and the appearance of ageing skin. Koppā pairs that ingredient focus with practical everyday formats. Ingredient research is not proof of a specific result from the finished set; our science guide explains the distinction.

Is the Protocol only for the face?

The routine goes beyond a single area. Use each formula as directed, with the Face + Body Balm Stick offering targeted moisture for dry areas on the face, neck and body. It is a convenient way to add extra conditioning without another all-over moisturising step.

What can I look forward to with consistent use?

A routine focused on skin that feels hydrated, softer and more comfortable, with a smoother-looking finish. Visible changes vary with your skin, consistency and wider routine, so we do not promise a fixed timeline. Start gradually, patch test each new formula and build a routine you enjoy returning to.
