Stratum Skin

Know your skin.
Make better choices.

Stratum Skin is a skincare decision making tool, delivered in an app format. It gives you an evidence-led routine, build around your skin.

How it works

A routine that works for you.

We start with you and consider which ingredients suit you and your needs, not the other way around.

Map your skin

Tell us how your skin actually feels and responds, and what you are working toward.

Get your routine

A personalised recommendation with the reasoning behind every step.

Review and adjust

Check in regularly. As your skin changes, your routine changes with it.

The detail

Everything about your skin, in one place.

Start with how your skin actually works.

No more piecing it together from scattered notes and half-remembered product names. Stratum maps how your skin is really functioning, not what is trending.

Know why an ingredient works.

Browse an ingredient glossary written for accuracy, grounded in scientific research, industry safety bodies, and government regulators.

Get a routine you can trust.

A personalised AM and PM routine that explains why each step is there, and evolves as your skin changes, remembering what has worked. You will see where the evidence is genuinely strong, or honestly thin.

The why

Sound familiar?

“I am spending more on skincare than ever, and I am less sure than ever that any of it is right.”

Stratum is the voice of reason in a noisy industry, on your side, not the brands.

A note from the founder

Why I built Stratum

I am a general practitioner, and I kept meeting the same problem. People were spending real money on skincare and following multiple influencers, but did not know if any of it was right for them. They felt caught between marketing trends and their own reality, growing unsure of what they were doing, and why. And truthfully, I was one of them.

I wanted a tool I could trust myself. So I built one.

Stratum Skin gives you a routine generated with deterministic logic from the best available ingredient evidence. It keeps a record over time, so you can see what is actually working. It checks your routine for ingredient conflicts and keeps the steps in order.

Good skin is not vanity. It is about health and wellbeing, and it deserves the same clear thinking we give the rest of our health. Stratum Skin is here so you can stop chasing and start trusting what you are doing.
