Daily Firm Serum
DAILY FIRM SERUM · 30 ML · FOR SKIN IN ITS 40s AND 50s
Two percent. Printed on the front. Not buried on the back.
A lightweight peptide serum with 2% Hexapeptide-11, 1% Ginkgo Biloba and hyaluronic acid. It supports the look of firmer, more elastic skin and softens the look of fine lines. Two pumps, morning and night.

| Hyaluronic acid | Hydration |
The 1% rule nobody on the shelf tells you about.
In the US, ingredients above 1% must be listed in order, from most to least. At 1% or below, they can be listed in any order. Find phenoxyethanol, a preservative almost always used at 1% or less, on the back of your current serum. If the hero ingredient comes after it, you paid for the name, not the dose.
We print the percentage on the front, so you never have to decode it.
A peptide is a memo to your skin that says "keep building."
After 40, your skin still listens. It just receives fewer memos. Hexapeptide-11 is labeled EMERGING: its strongest data so far comes from lab research on skin cells, not large human trials. Most brands would round that up. We won't.
The honest timeline
- Night 1: skin feels smoother and more comfortable.
- Week 2: better hydration.
- Weeks 4 to 8: skin looks firmer. Lines look softer. Gradually.
Results vary. Anyone who promises you otherwise is selling.
