Four products. One standard.
why we are different
We test what almost no one else tests.
Some chemicals used in cosmetics can interfere with the body's hormone signals. Almost no one checks for it. Not brands. Not even the companies that make the ingredients. We test every finished formula, whole, because chemicals behave differently together than alone. It is called the cocktail effect.

Shop nowEpigenetics is the science of how we age.
It connects biology, environment, and time. It helps explain not just how skin ages, but why. Our work began there, in 2016, before a single product launched.
It is also why we test the whole formula for endocrine disruption. When hormones are part of how skin ages, what you put on skin matters.

Menopause, and what it does to skin
Hormones shape skin all through life. But no change is larger, or less understood, than the one that comes with menopause. And most of what...

Let customers speak for us
My complexion is flawless with this range of products
Love every single product…….retinal and vitamin C serum are fabulous!
Works great on my skin, speaking as a 74 year old…..👏👏🙂
I just love the feel of my skin after using the serum and would definitely recommend. ☀️
My skin has really benefitted from this Vitamin C serum in oil. It soaks easily into the skin and I have seen improvements within a week of using.
Feels good putting something onto my skin that is natural and will nourish, without the harmful chemicals
Early days but I’ll stick with this vitamin c as I love the way it goes on and into my skin, I feel like it’s actually doing something.
I have several of your products and love all of them. I am 74 with the inevitable wrinkles, however the quality of my skin has improved……more plump, more even in tone and just healthier all round 🙂
I have used what feels like hundreds of different skincare brands over the years. I always had pretty robust skin but then after some microblading, I developed erythematotelangiectatic rosacea. I tried all of the usual brands who supposedly “helped” symptoms. I tried laser. Then I entered perimenopause so my skin worsened again. I’d given up finding a solution and then I came across skin diligent. I’m a few weeks in to using the products and my skin feels the healthiest it has in 10 years. My redness has significantly decreased too. I still have hormonal flares but it’s nowhere near what it has been previously. It’s honestly like liquid gold.
I use this cream at night time. It is part of my very simple night time regime, after using the hydrating serum I then use this cream over the top. It goes into my skin beautifully and leaves my skin feeling soft but not sticky. It is helping to brighten my complexion and even my skin tone. Wonderful from day one.
I thought I’d try this one for a change having previously used another rival brand with similar ingredients, think this is actually a more superior product and love the way it makes my skin feel- it really drinks it in
Very positive. Love how it feels on the skin.
A lovely product that nourishes and revitalises my skin in the morning.
My complexion looks brighter and my skin feels better hydrated.
It has become part of my routine.
