Seven actives

The actives

We work with a short list of proven actives, one to a formula, each at a stated concentration. If you know before you buy that vitamin C can tingle and that retinaldehyde needs easing in, neither is a surprise later.

Vitamin C

Stabilised L-ascorbic acid at a stated 15%. Brightens tone and supports collagen. Used in the morning, under sunscreen.

What it does

  • Brightens the look of uneven tone and dullness with daily use over several weeks.
  • Supports the skin's own collagen and helps defend against daytime environmental stress.
  • A light tingle on first use is normal; a real sting on broken or freshly-exfoliated skin is not.

In your routine

Stated at 15% L-ascorbic acid. A morning active, worn under moisturizer and sunscreen.

How to use

  • Apply to clean, dry skin in the morning, before moisturizer.
  • Always follow with sunscreen — vitamin C works alongside SPF, not in place of it.
  • Store away from light and heat; a serum that has turned deep orange has oxidised and is past its best.

Retinaldehyde

A retinoid one step stronger than retinol and gentler than the strongest clinical retinoids. Night use only, built up slowly.

What it does

  • Smooths the look of fine lines and refines texture with consistent night use.
  • A retinoid one step stronger than retinol and gentler than tretinoin.
  • Expect a short adjustment period — some dryness or flaking as skin acclimates.

In your routine

A night active only, introduced slowly — two or three nights a week to start, then built up.

How to use

  • Use at night on clean, dry skin, then moisturize.
  • Start two or three nights a week and increase as your skin tolerates it.
  • Not for the same night as exfoliating acids, and not for use during pregnancy or breastfeeding — pause and speak to your doctor.

Niacinamide

Vitamin B3 at 5%. Calms redness, refines the look of pores and supports the barrier. One of the easiest actives to tolerate.

What it does

  • Calms the look of redness and refines the appearance of pores.
  • Supports the skin barrier and is one of the easiest actives to tolerate.
  • Layers comfortably with most other actives, morning or night.

In your routine

Vitamin B3 at 5%. Suits morning or evening use, on most skin types.

How to use

  • Apply after cleansing, before your heavier creams.
  • Can be used morning and night.
  • Introduce it alongside other actives one at a time, so you can tell what your skin is responding to.

Exfoliating Acids

Glycolic (AHA) and salicylic (BHA) acids at a stated strength. Lift dead surface cells; not for use every night.

What it does

  • Lift dull surface cells so skin looks smoother and more even.
  • Glycolic (AHA) works on tone and texture; salicylic (BHA) works into oil and pores.
  • Can sting on broken or sensitised skin — patch-test before the first full use.

In your routine

At a stated strength. A few nights a week, not every night.

How to use

  • Use at night, a few times a week, on clean skin.
  • Do not use on the same night as retinaldehyde.
  • Follow with moisturizer, and sunscreen the next morning — acids leave skin more sun-sensitive.

Hyaluronic Acid

Multi-weight sodium hyaluronate and glycerin. Draws water into the upper layers of the skin. Layered onto damp skin.

What it does

  • Draws water into the upper layers so skin feels plumper and looks dewier.
  • Multi-weight, so it hydrates at more than one depth.
  • Works best layered onto damp skin, not dry.

In your routine

Sodium hyaluronate with glycerin. Morning or night, under moisturizer.

How to use

  • Apply to damp skin, then seal it in with a moisturizer.
  • Use morning and night, as often as you like.
  • In very dry air, layer it over a hydrating mist rather than onto dry skin.

Ceramides

Barrier lipids in a physiological ratio. They are what a compromised or over-exfoliated barrier is short of.

What it does

  • Replenishes barrier lipids so skin feels less tight and less reactive.
  • It is what a compromised or over-exfoliated barrier is short of.
  • Suits sensitive and post-active skin, and is very hard to over-use.

In your routine

Barrier lipids in a physiological ratio. A morning or night moisturizer step.

How to use

  • Use as your moisturizer step, morning and night.
  • Reach for it more often when skin feels tight after using actives.
  • Pairs comfortably with every active in the range.

Mineral Filters

Non-nano zinc oxide and titanium dioxide. Sit on the surface and reflect UV; suitable for reactive and post-procedure skin.

What it does

  • Sits on the surface and reflects UV rather than absorbing it.
  • Non-nano zinc oxide and titanium dioxide; suits reactive and post-procedure skin.
  • Can leave a light cast on deeper skin tones — a known trade of mineral filters.

In your routine

Broad-spectrum mineral filters. Every morning, as the last step.

How to use

  • Apply as the final morning step, over your moisturizer.
  • Use enough — a thin layer under-delivers the stated protection.
  • Reapply through the day when you are outdoors.
