Common questions

Most people feel softer, more hydrated skin within the first week or two. Visible firmness and fine-line improvement build over 8–12 weeks as collagen remodeling progresses. Our 60-day guarantee covers you well into that window.

Completely. 60 days is enough to feel whether your skin is responding — and most people notice changes well before that. Use the entire jar. If you’re not convinced, email us for a full refund. We don’t even ask you to return it.

We publish every concentration. Most peptide serums use “proprietary blends” that hide how much active ingredient you’re actually getting. Our GHK-Cu is at 1% — you can verify this and compare it directly to the published research cited on this page.

Use a pea-sized amount once daily at night, after cleansing and before any other products. Warm between your fingertips for a few seconds, then press gently into face and neck — don’t rub. One jar lasts roughly 30 days with once-daily use.

The formula contains only 8 ingredients with no fragrances, essential oils, or synthetic preservatives. We recommend a 48-hour patch test before full application. If irritation persists beyond the first few weeks, discontinue use.

Who this is for

  • Want firmer, smoother skin without a complicated routine
  • Done guessing what’s actually in your skincare
  • Looking for real concentrations backed by real research
  • Ready for a product that’s transparent enough to prove itself

What to Expect

Your 12-week journey

WEEK 1-2

First signs

Skin feels softer and more hydrated. The tallow base restores moisture immediately while GHK-Cu begins signaling at the cellular level.

WEEK 2-4

Skin responds

Your skin is actively remodeling collagen. Some users notice temporary dryness or fine lines — a sign the peptide is working beneath the surface.

WEEK 4-6

Turning point

Texture smooths out. The initial adjustment resolves as new collagen fibers mature and strengthen.

WEEK 6-8

Visible change

Firmness improves. Fine lines soften. Others start noticing the difference before you do.

WEEK 8-12

Full transformation

Peak results — measurably firmer, smoother skin. This is the window documented in clinical research.

WEEK 12+

Sustained results

Ongoing use maintains and builds on your results. Your skin’s collagen renewal cycle is now supported continuously.
