How One Oil-Based Serum Does What Water-Based Serums Can't
Five reasons this Spanish formula behaves differently on your skin.
Four Forms of Vitamin C
Pure ascorbic acid, an oil-soluble Vitamin C ester (ascorbyl isostearate), plus the Vitamin C naturally present in Spanish bitter orange and lemon oils. Most serums rely on one form. This one layers four.
Oil-Based Delivery That Works With Your Skin
Your skin's surface is built to repel water. An oil-based serum behaves like your skin's own sebum, so it absorbs into the skin instead of sitting on top of it.
Zero Water, Zero Dilution
There is no water in this formula, and Vitamin C in water is notoriously unstable. Waterless means the actives stay potent from the first drop to the last.
Kiwi Seed Oil for a Silk Finish
Lightweight kiwi seed oil melts in fast and leaves a soft, non-greasy finish, so the serum layers under makeup or moisturizer without a trace.
Clear Glass, Nothing to Hide
A stable formula does not need dark plastic to hide color change. We bottle in glass so you can see exactly what your skin is getting, every time.
32 women. Independent Spanish lab. ICH protocols.
The Clinical Results Most Skincare Brands Won't Show You
The Vitamin C formula was evaluated by Gaiker and Dr. Goya Analysis in Spain. Here is what the volunteers measured and reported:

The story behind the serum
Hi, I'm Ava-Ann
If you've tried everything... so had I. I understand. Department store counters, drugstore shelves, serums that promised the world and left me with irritated skin, an empty wallet, and the same mirror.
So I looked closer. What did I find? Most Vitamin C serums are mostly water. And Vitamin C in water is fragile. It degrades in the bottle before it ever reaches your skin. That's often why nothing seemed to work. It was never your skin.
That's why there's Noche Y Dia. Made in Spain from hand-selected Spanish oranges, as an oil-based serum with no water at all. Four forms of Vitamin C, bottled in clear glass because we have nothing to hide, and imported in limited quantities.
I don't expect you to take my word for it. That's why every bottle carries a 1-year guarantee, and it's a returnless one: if you don't love your skin, keep the product and we refund you in full.
Take a photo before you start. In a few weeks, I hope you'll be writing to us like Paulette, whose sister-in-law noticed before she said a word.
Warmly, Ava-Ann
Why Spanish Oranges Are Different
The Mediterranean has been Europe's orange grove for a thousand years. That heritage is in every bottle.
1. Hand-Selected Spanish Oranges
The Vitamin C in this serum begins with bitter oranges and lemons grown under the Mediterranean sun, selected by hand for the formula.
2. The Scent Is the Ritual
Warm citrus, like an orange grove in the sun. Customers describe it as a vacation in a bottle. It's the natural aroma of real Spanish citrus oils, not a lab fragrance recreation.
3. Made Under European Standards
Formulated and bottled in Spain under European cosmetic regulations, then imported to the US in limited quantities.
Oil-Based vs. Water-Based
The difference isn't the Vitamin C. It's how it gets to your skin.
| Noche Y Dia Serum | Typical Water-Based Serum | |
|---|---|---|
| Base | Oil, like your skin's own sebum | Mostly water |
| Vitamin C forms | Four | Usually one |
| Stability | Waterless, stays potent in the bottle | Prone to degrading in water |
| Bottle | Clear glass, nothing to hide | Dark or opaque plastic |
| Feel | Silky, absorbs fast, warm citrus scent | Often watery or tacky |
Better skin, or your money back. You have a full year.

Ingredients
The ingredients make the serum. Most Vitamin C serums are mostly water carrying a single fragile form of Vitamin C (levels 1 and 2). We start with hand-selected bitter oranges and lemons grown under the Mediterranean sun and climb the whole ladder.
- Level 1: water-based, single form of Vitamin C
- Level 2: dark bottle to hide color change
- Level 3: stabilized derivative, still diluted in water
- Level 4: natural citrus oils
- Level 5: oil-based, zero water dilution
- Level 6: four forms of Vitamin C, Spanish oranges, glass
High Quality
The Vitamin C begins with hand-selected bitter oranges and lemons, cold-pressed into the oils that carry the formula. We bottle in clear glass because a stable formula has nothing to hide.
Formulas
Typical serums are largely water and fillers. This formula uses zero. Everything in the bottle has a purpose for your skin, which is why it stays potent from the first drop to the last. Made in Spain under European cosmetic standards and imported in limited quantities.
