Why we stand behind it
Formulated in France with longevity scientists, this serum uses a rare, lipid-form Vitamin C molecule that does not degrade in light - meaning it can be used morning or night without concern. Its triple antioxidant system of Vitamin C, E, and punicic acid delivers prolonged protection against free radicals from UV exposure and pollution, visibly brightens and evens skin tone, and strengthens the skin barrier. The texture is luxuriously dry and absorbs instantly with a non-greasy finish - suitable for all skin types including sensitive and blemish-prone. The Vitamin C serum that finally gets it right.
In a 28-day independent study, 100% of testers noticed improved skin appearance and more hydrated skin, 95% saw a more even complexion, and 90% noticed a reduction in fine lines. Tested free of hormone disruption.
Key ingredients
Ascorbyl Tetraisopalmitate (Vitamin C): A powerful, non-photosensitive antioxidant that visibly brightens and evens skin tone.
Pomegranate Extract: Rich in punicic acid. Soothing. Visibly targets blemishes and the appearance of fine lines.
Hemp Seed Oil: Rich in omega 3 & 6. Deeply nourishing. Strengthens the skin barrier and limits dehydration.

create accountOur skin is in conversation with everything around it - the air, the light, the choices we make, and everything we apply to it. Epigenetics is the science of that conversation. It is the science of how our environment shapes the way we age. It is also the science that brought Skin Diligent into existence. Skin Diligent is a French epigenetic laboratory where the biology of longevity and the science of skin converge. Our research is led by a biologist and former Institut Pasteur scientist. Our formulas are conceived to act at the epigenetic level - supporting the biological processes that determine not just how our skin looks today, but how it ages over the years ahead. Every finished formula is tested free of estrogenic and androgenic endocrine disruption. Not individual ingredients. The whole formula. Because at the epigenetic level, what touches our skin matters completely. Each product is independently clinical tested and made to the highest standards of longevity science - born from years of asking what skincare could be if safety and efficacy were never separated. Dermatologist tested. Hormone Safe Tested. Skin Diligent.

"This was recommended in store while I was looking for a vitamin C. I was excited to use and now that I have been using for about 1.5mos I haven’t really noticed any benefits."
— Katrina N. (2/5)
"Love this vitamin C serum! It's unlike any other I've tried - a thin, super hydrating oil with a beautiful, light scent. It absorbs very quickly and plays well with my other serums and actives. I might be a bit too gentle to ultimately make a significant difference for my skin in particular, but I'll certainly enjoy using the bottle until the end to make a fair assessment."
— Joe V. (5/5)
"I have only used this product for a week now, but so far so good. It has a nice texture & goes on nicely."

— Audrey (5/5)
"This serum has been part of my routine for three years and has evened out my skin tone. My sun spots have faded significantly and even disappeared. It helps me maintain beautiful skin despite the passing years."
— AURELIE B. (5/5)
"I follow my little routine every morning: moisturising oil and vitamin C oil. In the evening, I apply retinol and Exosome Advanced cream. My husband has never complimented me so much on my skin. . . he thinks it looks more beautiful 😍"
— Ana V. (5/5)
"I've been using the serum for a year now. It makes my skin glow. It absorbs easily and nourishes my skin well. My skin is very smooth. As for my melasma, I haven't seen any difference, especially this summer."
— Linda D. (4/5)
"Since I've been using it, my skin looks better, has fewer imperfections, is more hydrated, my pigmentation spots have reduced and my skin no longer feels tight! Just a little expensive!"
— Melanie S. (5/5)
"Perfect for my dry skin. Moisturising serum isn't enough for me, but the Vitamin C serum complements it perfectly. I still need to apply a nourishing cream on top."
— Sylvie P. (5/5)
