Beta GHK-Cu Glow Set

$249.00

Meet the Beta GHK-Cu Glow Set: a two-month introduction to the ingredient quietly rewriting the rules of modern skincare. Built on 2% pure GHK-Cu — the most studied copper peptide in the category — this clinical-strength duo is designed to work as one continuous system. The Signal Serum tells your skin what to do. The Renewal Cream gives it everything it needs to do it.

We're offering this beta because we wanted to launch with real evidence — not a hunch. One hundred people, two months, honest feedback. Your photos, surveys, and honest reviews shape what comes next — every contribution welcome, none required.

The serum delivers. The cream holds it there.

Known for

GHK-Cu is one of the most-studied copper peptides in dermatology — a tripeptide your skin produces in your twenties and quietly stops making with age. In research and in practice, it's known for signaling repair, supporting collagen, and restoring the look skin loses over time.

What's inside

2× 2% GHK-Cu Signal Serum · 30 ml · the messenger.
A lightweight, fast-absorbing cobalt-blue serum that delivers clinical-strength copper peptide into the skin — where structural support begins.

2× 2% GHK-Cu Renewal Cream · 30 g · the anchor.
A sustained-release cream that seals the signal, delivers a second daily dose of GHK-Cu, and reinforces the barrier with Ceramide NP, Panthenol, and Vitamin E.

May help with

Fine lines & wrinkles. Smoothing the appearance of expression lines and surface texture over time.

Collagen. Activating fibroblasts — the cells responsible for natural collagen production.

Scar healing. Supporting the skin's natural repair process and the look of textured or uneven areas.

Hydration. Reinforcing the barrier to lock in moisture and reduce water loss.

Copper glow. The luminous, dewy finish copper peptides are famous for.

Morning and evening. Every day.

Consistency is what changes skin. Use the kit twice a day for eight weeks — the serum signals, the cream seals.

  1. Cleanse. Pat skin slightly damp — leave it that way.
  2. Signal Serum · 1–3 pumps. Press and tap into face, neck, and décolletége.
  3. Renewal Cream · pea-sized. Smooth on top to lock the signal in.
  4. AM: finish with SPF 30+. Every morning, no exceptions.
A few notes from us

Cleanse first, always. Wash your face before applying the serum and cream so the products absorb cleanly without buildup.

Sensing irritation? Pull back on the cream — switch to once daily or every other day until your skin settles.

With your routine

GHK-Cu plays well with most of your shelf — with one exception. Copper peptides and vitamin C cancel each other out.

Pair freely
Niacinamide, hyaluronic acid, peptide complexes, ceramides, sunscreen.
Space out
Retinol, AHAs, BHAs. Use on alternate nights — the kit one evening, exfoliants or retinoids the next.
Pause or Alternate
Vitamin C (L-ascorbic acid). Copper oxidizes ascorbic acid. Pause C for the eight weeks of the beta, or alternate a.m. / p.m.

You're one of 100. When your kit arrives, you'll get a welcome email with everything you need to participate — links, dates, the full guide. Here's the short version.

Before · Week 4 · Week 8
Photos and a short video. Three rounds — before you start, midpoint, and at the end. Same lighting, no makeup. A short video clip at each point if you can.
Across the 8 weeks
Two or three quick surveys. About five minutes each, sent at milestones across the beta.
Week 8+
An honest testimonial. Written or on camera, only if you have one to give. Including "this didn't change my skin" — honesty is worth more than a glowing review.

All appreciated, none required. The kit is yours either way.
