Not every Vitamin C is built the same.
Most Vitamin C serums lose their potency within 90 days. Ours doesn't. Here's why.
Oil-based, 4 forms of Vitamin C
- Oil-based formula keeps Vitamin C stable to the last drop
- Contains Ascorbic acid, Bitter Orange Oil, Lemon Oil, and Kiwi Seed Oil
- Made by Laboratorios Ximart S.A., a Spanish dermatology lab
- Clinically tested on 32 women over 28 days
- Glass bottle, no degradation, no plastic leaching
- Paraben-free, gluten-free, cruelty-free
Water-based, mass-produced
- Water-based formulas oxidize and lose potency in 90 days
- Synthetic ascorbic acid, no botanical origin
- Made for shelf life, not your skin
- Marketing claims, rarely third-party clinical data
- Plastic or dark-amber bottles, often to hide oxidation
- Common preservatives, fillers, and fragrance loads
Tested to European clinical standards.
Conducted by Gaiker and Dr. Goya Analysis, two of Spain's independent research institutions, the kind of substantiation most US skincare brands simply don't have.
"My skin is as clear and soft as a child's."
I've been using the Noche Y Dia Vitamin C oil for about 2 years now. I can't praise it enough. I'm 68 years old and my skin is as clear and soft as a child's. My husband loves to touch my face and tells me daily how beautiful I am. Under-eye lines and bags look improved.
"Beats the cosmetic heavy hitters."
Over the years I worked in the cosmetic industry for some of the heavy hitters. In comparison, price point to product quality and effectiveness, I believe this beats them all. I am 70 years old and my skin looks better than ever. Take the plunge, you'll be amazed.
"Smells like a vacation on the Amalfi Coast."
I have been using the Vitamin C Serum for over 2 years. I cannot live without it. It melts right into my skin. This is the only product I have ever used morning and night because I love it so much. It smells like you are on vacation in the Amalfi Coast. I have referred this to every one of my friends.
