Our Lab

A laboratory of single-actives.

OCTAVE LAB is built on one belief: the best skincare formulas are the ones you can read.

Every OCTAVE serum is a single-purpose concentrate. One hero peptide, formulated at the upper bracket of published in-vitro efficacy, in a vehicle clean enough not to fight it. No actives stacked on actives to justify a price tag. No fragrance, no essential oils, no claims we can't back with a third-party batch test.

The eight-note brand mark

The line of eight dots on every bottle is a literal reference: an octave. Eight steps, no improvisation. Each product is one note in a complete routine — stack as many as your skin needs, skip the rest.

What we never do

• We never make medical claims. OCTAVE products are cosmetic, topical, and intended only for the skin surface.
• We never inject anything. There are no needles, no injectables, no “reconstitution” — our serums are open the bottle, three drops, go.
• We never under-dose. Concentrations are printed on the front of every bottle.
• We never reformulate without telling you. Major changes get a heads-up email to existing customers four weeks before the new batch ships.

Where we make it

OCTAVE products are formulated and filled in EU-licensed cosmetic manufacturing facilities. Every batch is third-party tested for peptide identity and purity. The certificate is available via the QR code on each box.

How we got here

OCTAVE LAB was founded in 2026 in Madrid by a small team obsessed with the gap between what is written on a peptide label and what is actually in the bottle. Most cosmetic peptide brands print a name on the front and a percentage nowhere. We wanted the opposite. So we built the smallest possible range we could be proud of — five serums, one hero peptide each, every concentration printed in monospace under the product name — and shipped it under one rule: never put a word on the bottle we couldn't back with the lab assay.

The scientific advisory team

OCTAVE LAB is supported by an independent scientific advisory team of biochemists with a combined twenty-plus years in peptide formulation. They sign off on every reformulation before a batch is poured.

Where we're going

Two more single-active serums by Q1 2027. A return-and-refill program for empty amber bottles by Q4 2026. A printed compendium of every active and every concentration we ship, mailed to every customer with their first order. No additional channels, no influencer launches, no “spa edition” packaging.

If that sounds calm, it is meant to.
