One habit, two causes.

Most people reaching for concealer are covering marks that won't fade, or a face that looks tired regardless of how it slept. They look like the same problem in the mirror. They aren't — so this is two serums rather than one bottle claiming to do everything.

  • 01 · Morning · Cellular Clarity — Every brightener makes the spot lighter. This one closes the gap. One dosed pigment route rather than four at a fraction of a percent each: Delentigo™ Swiss garden-cress sprout extract at 4%, the concentration its maker's age-spot studies used. Vitamin C ester, kojic acid and arbutin are in the bottle as base conditioners — named on the label, claimed nowhere.
  • Safety Contains soy · 0.34% alcohol. Vegan.

  • 02 · Night · Cellular Renewal — For skin that looks rested and full rather than thin and tired. Salmon-derived polynucleotides at 5% — the maximum concentration their supplier has tested — with MossCellTec™ No. 1 at its studied 2%, and PhytoCellTec™ Swiss apple fruit cell culture at 1% against a 2% study, which we print rather than round away.
  • Safety Contains fish. Not suitable for vegans or anyone with a fish allergy.

HOW TO USE

One in the morning. One at night.

Morning

Cellular Clarity, after cleansing, before moisturiser. Then sunscreen, always.

Night

Cellular Renewal, after cleansing, before moisturiser.

Bare

Lightweight and layer-friendly. Made to be worn bare — makeup optional.

Most brands name the ingredient. We match the dose.

The research belongs to the ingredients and was run by Mibelle Biochemistry, their Swiss maker — supplier research, not independent studies, and not studies of these finished serums. One number here does not flatter us. It is printed anyway.

  • Swiss actives — Mibelle AG
  • PhytoCellTec™ — patented by Mibelle in five countries
  • Every dose printed on the page
  • 60-day refund — opened or not, nothing to send back

Safety Contains fish and soy. Patch test 48 hours before first use.

Safety For external use only. Avoid the eye area. Patch test 48 hours before first use. Discontinue use if irritation occurs. Use sunscreen when exposed to sunlight. Keep out of reach of children.

FAQ

Why not just one serum?
Because tone and the look of tiredness need different actives. One bottle claiming both is one bottle doing neither properly.
Is Renewal vegan?
No. It contains salmon-derived DNA. Cellular Clarity is vegan.
How long does each bottle last?
30 ml each. Used as directed, both bottles cover roughly a two-month routine.
When will I see something?
No date. Anyone who gives you one is guessing.
Will it lighten my whole face?
No — and that is the entire point. Most brighteners act everywhere they are applied, which is why the spot fades and the skin around it fades with it. In Delentigo™'s eight-week study the pigment reading in treated spots fell 26% while the normally pigmented skin around them moved 16.5%, closing the visible contrast between the two by roughly half.
