$[PLACEHOLDER] · pricing at launch
Why ours is better

Matrixyl Anti-Age Cream

Matrixyl (palmitoyl peptides) in a daily cream — for the look of softer, smoother fine lines.

$[PLACEHOLDER] · pricing at launch
Why ours is better
- The real Matrixyl % goes on the jar. At trace doses it's a marketing ingredient — we don't do trace doses. [VERIFY formula]
- A simple, barrier-friendly base — not a 40-ingredient filler deck around one active.
- Batch-dated with a COA, like everything we make.

Clinical Vitamin C Cream

Vitamin C for the look of brighter, more even-toned skin — in packaging that actually protects it.

$[PLACEHOLDER] · pricing at launch
Why ours is better
- The exact form and % of vitamin C, printed — not a vague "vitamin C complex."
- Opaque, air-restricted packaging — vitamin C degrades in light and air, so a clear jar is a red flag. [VERIFY packaging]
- Batch-dated so you know it's fresh — not shelf-aged into a brown, spent cream.

Collagen + Vitamin B + Hyaluronic Acid Gel

A featherweight hydration gel — multi-weight hyaluronic acid, vitamin B, and collagen doing what collagen actually does.

$[PLACEHOLDER] · pricing at launch
Why ours is better
- Honest about collagen: applied to skin, it can't "rebuild" anything — it's a surface hydrator that binds water. We say so out loud.
- Hyaluronic acid disclosed by molecular weight — different weights hydrate at different depths. [VERIFY formula]
- No stinging "actives theater" — real hydration should feel like nothing at all.

Peptide Firming Eye Cream

Peptides for the look of firmer, brighter under-eyes — formulated for the most unforgiving skin on your face.

$[PLACEHOLDER] · pricing at launch
Why ours is better
- Fragrance-free and essential-oil-free — it sits millimeters from your eye. [VERIFY formula]
- No mica or optical blurrers pretending to be results — if it looks better, it's your skin.
- The peptide % is printed on the label, same as everything else we sell.

Probiotic Microbiome Bifida Cream

Bifida ferment for a calmer-looking, more resilient-feeling moisture barrier.

$[PLACEHOLDER] · pricing at launch
Why ours is better
- Labeled honestly: "probiotic" creams don't contain live cultures — this is a ferment lysate, at a disclosed %.
- A minimal, barrier-first base — the fewer ingredients, the fewer ways to irritate. [VERIFY formula]
- Every batch third-party tested, COA on request.
