We created our Cell-to-Surface™ standard to test the real product, not just the individual ingredients. Because what matters is how the finished product performs when you actually use it.

We look at the evidence at three levels:

CELL
What is the finished formulation actually doing biologically within the skin?

SURFACE
Are those changes reflected in objective clinical measurements of the skin?

MIRROR
Do the people using it actually see and experience meaningful improvements?

For us, the evidence comes first. The claim comes after.

Ingredient-scanning apps can make skincare feel reassuringly simple: scan a product, get a score, make a decision.

But ingredient safety is not that black and white.

As toxicologist Rani Ghosh explains, many apps assess ingredients in isolation, without taking into account the dose, level of exposure or the finished formulation. The fact that an ingredient can cause harm under certain conditions doesn’t automatically mean it is unsafe in the way it is actually being used. Context matters.

For anyone who wants to understand what’s in their products without being told what is simply “good” or “bad”, COSMILE Europe is a science-backed resource designed to inform rather than alarm.

If you’re investing in your skin’s future, protection has to be part of the plan.

Daily UV protection helps defend against the damage that contributes to visible skin ageing, helping to preserve the results you’re investing in.

Protect first and build from there.

Powerful skincare doesn’t have to come with irritation.

Night Repair Therapy was created to deliver meaningful skin renewal without the irritation often associated with retinoids.

Its finished formulation has been independently tested on human skin, with 98% of users saying it felt gentle on their skin and 93% reporting no irritation over 12 weeks.

Effective enough to deliver proven results. Gentle enough for sensitive skin.

We love hearing that Age Defence is making mornings simpler.

Skincare doesn’t need to be complicated to be effective.

There’s something about September that feels like a reset; a chance to get back into routine, including our skincare.

But some mornings are a little more rushed, and by nighttime, we’re ready to get into bed as quickly as possible. The last thing we want is more steps.

The Complete Skin Ageing Duo keeps things simple.

Two products. Morning and night. A simpler routine, without compromising on results.

Fibrillin might not be as well known as collagen, but it plays an important role in the structure and elasticity of our skin and is one of the earliest components to decline with sun damage.

As part of the Cell stage of our Cell-to-Surface™ standard, biopsies of photoaged human skin were examined to see what Night Repair Therapy was doing within the skin itself.

Night Repair Therapy doubled fibrillin-rich microfibrils, performing comparably to the topical retinoid tested. It also stimulated organised collagen production, a response not seen with the retinoid in this particular measure.

Proof that goes beyond ingredients alone, to what the finished formulation can do within the skin.

Pure Science. Proven Results.

Still pinching ourselves.
To have both of our products recognised in the Tatler Beauty Awards feels incredibly special.

This year, Age Defence was awarded in the Best Mature Skin category for Best Everyday Moisturiser, following Night Repair Therapy, which won last year for Best for Sensitive Skin in the Best in Mature Skin category.

We are so proud to see both products honoured by Tatler, a wonderful recognition of the science, care and expertise behind The Skin Diary.

We’re delighted that Age Defence has been recognised in the Tatler Beauty Awards, winning Best Everyday Moisturiser in the Best in Mature Skin category.

A brilliant moment for Age Defence, and such special recognition for a product we’re incredibly proud of.

Huge thank you to Astrid and the Tatler team for the recognition.

Proven by science. Loved by customers.
