About Us




In 2021 when co-founder Tule Park founded Skin Diligent, NOBODY talked about skin health. She started explaining, educating, teaching anyone who would listen about how crucial the sciences of epigenetics and microbiome were in our health and skin health. She remembers a lonesome courageous French press reporting on her vision in 2021 and retailers who had never heard of epigenetic skincare were dubious at best. 

But it was the cusp of many changes to come with Covid shaking up how we think about our health. Health and skin health started to matter to people. And Skin Diligent started to gain traction. In 2023, the brand was covered in over 30 major press articles and is proud of its hundreds of reviews with an average of 4.9 stars. The re-order rate for online sales surpassed 50%, a rate unheard of in the industry, making all of us involved in the brand extremely proud and a real testament to all our hard work. 


For men & women who desire healthy & radiant skin, Skin Diligent's epigenetic skincare products are clinically proven, science-based, efficacious formulas that target skin blemishes and premature skin ageing while improving skin quality.

Tule's previous work with several Korean cosmeceutical companies gave her the clarity of vision for a pioneering epigenetic & microbiome skincare brand in Europe. Unconventionally for the industry, she teamed up with a leading French ethnobotanist, researchers in biology and green chemistry to create efficient skincare products that are at the same time natural & cutting-edge science at accessible prices. You won't be paying for fancy packaging at Skin Diligent. 

We understand skin. We know intricately what gets absorbed and what stays on the surface. We take the responsibility of how our products affect your skin very seriously, that means not only the active ingredients, but also all the supporting ingredients in the formula. We test all our final formulas for oestrogen endocrine disruption, we use 100% natural perfumes and 100% natural preservative systems. You are right to think that not all natural is necessarily good. But in our case, it's all good. 

If you haven't tried it? We invite you to try any of our products or you may want to try our best seller, the Vitamin C Serum-in-Oil! We hope you will cross over to our bright world of healthy skin, where glowing skin is a side effect. 


Skin Diligent is London-based, French-made. We offer food supplements and skincare products.
