Home/Ingredients

Every ingredient, and why it's there.

We don't add ingredients for the label. Here is each active we use, the dose the evidence supports, what it pairs with, and where we'd tell you to be careful.

Barrier lipid

Ceramides

Rebuild the mortar between skin cells so water stays in and irritants stay out.

Vitamin B3

Niacinamide

Regulates oil, supports barrier lipid production, and evens tone over months rather than weeks.

Read the rationale →
Antioxidant · Brightening

Vitamin C

Neutralises free radicals, interrupts excess pigment production, and is required for collagen synthesis.

Read the rationale →
Tyrosinase inhibitor

Kojic Acid

Blocks the enzyme that begins melanin production, slowing new pigment at the source.

Read the rationale →
Anti-inflammatory · Depigmenting

Tranexamic Acid

Addresses the inflammatory and vascular drivers of melasma, not just the pigment itself.

Read the rationale →
Humectant

Hyaluronic Acid

Draws water into the upper layers of skin and holds it there.

Read the rationale →
Brightening

Alpha Arbutin

A gentler, slower-releasing route to the same target as hydroquinone.

Read the rationale →
Antioxidant

Glutathione

Shifts pigment production toward the lighter pigment type and neutralises oxidative triggers.

Read the rationale →
AHA · Exfoliant

Glycolic Acid

Loosens the bonds between dead surface cells so texture smooths and pigment clears faster.

Read the rationale →
BHA · Exfoliant

Salicylic Acid

Oil-soluble, so it works inside the pore rather than only on the surface.

Read the rationale →
Retinoid · Vitamin A

Retinol

The most evidence-backed anti-ageing active in skincare: speeds renewal, builds collagen, clears congestion.

Read the rationale →
Polynucleotide · Regenerative

PDRN

A DNA-fragment active associated with repair and elasticity, promising, and honestly still young as a topical.

Read the rationale →
Cell-signalling · Regenerative

Exosomes

Cell-derived messengers studied for skin repair: the most talked-about ingredient in aesthetics, and the youngest evidence base on this page.

Read the rationale →
Peptide · Collagen-signalling

Matrixyl

A signal peptide that nudges skin to make more of its own collagen: the gentle route to firmness.

The formulation principle

If an active is on the front of the box but below the preservative on the back, it is there for the box. We would rather name four ingredients we can defend than fourteen we can't.

. How we decide what goes in

Skin notes, four times a year.

No countdown timers, no restock panic. Four considered letters a year on formulation, ingredients and what the evidence actually supports, plus first word on anything new.
