About Mystifi

Mystifi is a copper peptide house. Four products, one molecule: a cleanser, a serum, a face cream and a scalp wash, all built around GHK-Cu, the copper tripeptide. There is no second range and no new hero ingredient every season. The interesting thing about this brand is how narrow it is.

One molecule

GHK-Cu is a small copper-bound peptide that occurs naturally in the body and declines with age. It has been studied for around four decades, most of that long before anyone put it in a moisturizer, and for a cosmetic ingredient the literature is unusually good: human studies with control groups, active comparators and measured outcomes.

That research is research into the ingredient, not into us. It is why we chose GHK-Cu; it is not evidence about our formulas, and we do not present it as though it were. Every figure quoted anywhere on this site is set out on the studies page next to the study it came from and what we say because of it. None of it is Mystifi testing its own products, because we have not run a study of our own yet. When we do, it goes on the same page.

Four steps, in order

The four products are a sequence rather than a collection, and the order is most of the point.

1. Cleanse. Activated charcoal lifts the day off without stripping the barrier the peptide has to work on. Morning and night.
2. Treat. The serum is the step that does the work: 1% GHK-Cu, pressed into jawline, neck and under-eye, then two minutes of nothing while it has the skin to itself.
3. Hydrate. The cream seals the serum in and carries a second dose of GHK-Cu through the day. It is blue because the copper is.
4. Hair. The same peptide above the neckline, as a low-foam scalp wash, two or three times a week.

Skipping a step is fine. The order is less negotiable: the serum wants clean skin and a moment to itself before anything goes on top of it.

Numbers instead of adjectives

We would rather print a figure than an adjective. The serum is 1% GHK-Cu and the page says so, rather than saying “clinical strength” and leaving you to guess. Every product carries its full INCI list in the Ingredients accordion, so the formula is readable before you buy it instead of after.

The same rule covers comparisons. Where this site sets GHK-Cu against something else, the study is attached to the claim and printed on the studies page.

What is in, and what is left out

• The cleanser, the serum and the face cream are fragrance-free.
• The scalp wash is sulfate-free, low-foam and colour-safe.
• All four are vegan, cruelty free and paraben free.
• The blue in the cream is the copper itself, not a dye.

What we will not say

Mystifi products are cosmetics. They cleanse, and they change how skin and hair look. They are not intended to diagnose, treat, cure or prevent any disease, and the copy on this site is written that way on purpose rather than by accident.

• We describe results the way the studies measured them: the appearance of firmness and density, the look of fine lines. We do not say a Mystifi product rebuilds, restores or regenerates anything.
• Ingredient research stays ingredient research. “GHK-Cu has been studied” is a sentence we can write; a sentence that quietly turns that into a test of a Mystifi product is not.
• The scalp wash is described only by what you can see and feel: a scalp that stays comfortable, hair that looks fuller and denser once it is dry. The hair evidence for GHK-Cu is much thinner than the skin evidence, and we say so on the studies page rather than borrowing the skin research to cover it.
• No ratings we have not earned. There are no placeholder stars on this site and no reviews we wrote ourselves.

If it is not right

Write to us from the contact page and a person answers. Returns and refunds are covered in our returns policy.

With anything new, patch test first: a little behind the ear or on the inner arm, then wait 24 hours. If a product stings or reddens, stop, rinse and tell us.

Shop the four steps, or read the research behind them first and decide afterwards.
