Why we stand behind it
This lightweight and deeply hydrating superfruit vitamin C serum is designed to reinforce skin barrier, repair damage to the skin’s outer layer and protect skin from daily environmental stressors and pollution while boosting hydration and soothing reactive skin. Extremely rich in naturally sourced vitamin C, omega-3 fatty acids and antioxidants, Le Sérum works to instantly plump, nourish and brighten the skin. EWG VERIFIED™, fragrance-free and Made in France.

91% of participants said skin is visibly plumped after using Le Sérum.*
*Based on clinical testing under dermatological control with a diverse group of participants, with ages spanning 20s to 70s, after 28 days of use.

An undertone is the color beneath the surface of your skin, which never changes (even with a tan). There are three types of undertones:
Pink/Cool
I see red or pink undertones around the perimeter of my face and neck.
My skin burns easily, but barely tans.
My skin looks better in silver jewelry than gold.
Neutral
I see both pink and yellow undertones around the perimeter of my face and neck.
My skin sometimes burns and sometimes tans.
My skin looks good in both gold and silver jewelry.
Yellow/Warm
I see yellow or golden undertones around the perimeter of my face and neck.
My skin rarely burns, but tans easily.
My skin looks better in gold jewelry than silver.

— Charlene (5/5)
"I like my skin care routine simple and quick so it was a leap to buy Le Sérum but I was sold on Doré’s formulation. I use it every day. Sometimes at night, too. It’s another skin care step but doesn’t feel like extra work. And my skin loves it."
— Jane M. (5/5)

"The texture of this Vitamin C is perfect and I love how plump and hydrated this makes my skin. It's perfection!"
— Erik M. (5/5)
"I have been using Dore products for around a month now, including the serum. I use the full routine, cleanser, serum, moisturiser and balm. All of these products are brilliant and have made a difference to my skin. The serum in particular is great and as soon as I apply it my skin looks better. The results are more even skin tone, skin looks fresher and plumper and I also think a touch more taut. I was looking for a simple but effective skin care system and more has definitely delivered! Before this I was using a multitude of products but honestly this simple routine is better then all of it and so easy to fit in to my busy life. There is even a travel set which I will be purchasing soon too. The serum is the cherry on the cake."
— Mhairi S. (5/5)
"Love this serum! My skin is reactive and this doesn't cause any redness, blotchiness or itching. Leaves my skin feeling so soft and supple; absorbs quickly and doesn't leave any stickiness."
— Jordan B. (5/5)
"I took a while to review these products as I wanted to road test and use for several weeks. This light serum is all I need and I'm 71. I've never liked too much product on my skin. ❤️"
