Your top questions
What makes Noche Y Dia Vitamin C Serum different?
Most Vitamin C serums are water-based, and skin is designed to keep water out, so they tend to sit on the surface. Noche Y Dia is oil-based and water-free, so it absorbs the way your skin's own oils do. It combines five sources of Vitamin C, comes in a glass bottle, and is made in Spain under European cosmetic rules.
How much Vitamin C is in it?
Our serum is not built around a single ingredient, so it is not measured by a single percentage. It combines five sources of Vitamin C in a water-free formula developed in Spain. Instead of a number, we show you what the formula does: in an independent clinical study, volunteers saw up to 30% fewer visible wrinkles in 28 days. More on our Vitamin C.
Is it clinically tested?
Yes. Our Vitamin C line was evaluated in an independent clinical study in Spain by Gaiker and Dr. Goya Analysis with 32 volunteers. Results included up to 30% fewer visible wrinkles and up to 30% firmer-looking skin in 28 days, a 19% improvement in the look of elasticity in 14 days, and 8 in 10 volunteers noticing more hydrated skin in 14 days. Individual results vary.
How fast will I see results?
Skin feels hydrated from the very first application, for up to 24 hours. In the clinical study, the look of elasticity improved by 19% in 14 days, and visible wrinkles were reduced by up to 30% in 28 days. See the week-by-week timeline. Individual results vary.
Is it greasy?
Not at all. It is silky and lightweight and sinks in within seconds, so you can follow with moisturizer and makeup right away. 97% of study volunteers said it left no greasy residue.
What does it smell like?
Like a Spanish orange grove in the sun. The fresh scent comes from real bitter orange and lemon oils, with no added perfume. 97% of study volunteers loved the smell.
Can I use it on sensitive skin?
It is made for mature, dry skin and is gentle enough for daily use, morning and night. Its scent comes only from natural citrus oils. As with any new skincare, if your skin tends to be reactive, try a little on a small area first. How to patch test.
How do I use it?
After cleansing, smooth a few drops over your face and neck, morning and night. Follow with your moisturizer, and with sunscreen during the day.
How many bottles should I start with?
Results build with daily use over several weeks, so our best value is the 3-bottle set. It lowers the price per bottle, unlocks free gifts and free shipping, and covers the weeks your skin needs to show what it can do. And with a full year to decide, there is no risk either way.
Is there a guarantee?
Yes. Every order is backed by our 365-Day Returnless Refund: if it is not your perfect match within a year, you get your money back, and on most orders you keep the product.
