Aurora Vitamin C Serum
Three forms of vitamin C, because one is never enough.
$20.00
Most vitamin C serums pick one form and hope. This one carries three — pure L-ascorbic acid for immediate activity, magnesium ascorbyl phosphate for stability, and 3-glyceryl ascorbate for gradual release through the day.
Vitamin C is the most rigorously studied antioxidant in dermatology. Applied topically over twelve weeks it produces statistically significant improvement in wrinkling, confirmed on biopsy by new collagen formation. Ferulic acid holds the whole system stable, and calendula and chamomile keep it comfortable enough to use every single morning.

The Evidence
What the research measured.
Vitamin C works through a mechanism that is understood rather than guessed at — and it is one of the few actives where the human evidence has been replicated for decades.
Forms of vitamin CImmediate, stabilised and time-release — covering delivery that any single form leaves incomplete.
To measured changeThe point at which randomised trials recorded significant wrinkle improvement, confirmed by biopsy.
PhotoprotectionFold-increase in UV protection reported for vitamin C combined with ferulic acid versus untreated skin.
Mechanism
How it works, at the level that matters.
Vitamin C is a required cofactor for prolyl and lysyl hydroxylase, the two enzymes that stabilise the collagen triple helix. Without enough of it, collagen is synthesised but never folds into a structure that holds.
It also donates electrons directly, quenching the free radicals ultraviolet light generates before they can fragment the collagen you already have. And it interrupts melanogenesis by reducing dopaquinone back to DOPA — which is why consistent use evens tone as much as it firms texture.
The three-form approach solves the oldest problem in vitamin C chemistry. Pure L-ascorbic acid is the most active and the least stable. Magnesium ascorbyl phosphate is pH-neutral and survives where ascorbic acid degrades. 3-glyceryl ascorbate converts gradually in the skin. Together they cover immediate delivery and sustained availability, and ferulic acid protects all three from oxidising in the bottle.

The Formulation Story
Why we made
this one.
Almost every serum on the shelf claims vitamin C. Very few tell you which form, and form is most of the story.
L-ascorbic acid is what the research used, but it is unstable enough that a poorly built serum is inert within weeks. The derivatives are stable but need converting in the skin. Choosing one means accepting its weakness.
So this formulation does not choose. Three forms, ferulic acid to hold them together, and a base of rice, calendula and chamomile extracts that makes a low-pH serum something you will actually reach for at seven in the morning.

Formulated for
Anyone starting a serious topical routine, and anyone whose concerns are dullness, uneven tone, early photoageing or post-inflammatory marks. It is the foundation of the Omnivia morning ritual and layers directly under the Ageless Retinol Moisturizer.
The Formulation
Every active. Every milligram.
Every active, named. No amounts withheld. If it is in the bottle, the quantity is printed here — because a dose you cannot verify is a claim you cannot check.
Serving size

1 fl oz / 30 ml
L-Ascorbic AcidPure vitamin C
The unesterified, bioactive form — the molecule the dermatological research used.
Magnesium Ascorbyl PhosphateStabilised vitamin C
A pH-neutral derivative that stays stable where pure ascorbic acid degrades. Works alongside, not instead.
3-Glyceryl AscorbateTime-release vitamin C
A third form, converted gradually in the skin, extending delivery through the day.
Ferulic AcidFerula foetida derived
Plant polyphenol that stabilises vitamin C against oxidation and extends its photoprotective effect.
Calendula & ChamomileOfficinalis · Recutita
Botanical extracts that calm the mild sting a low-pH vitamin C base can produce.
Rice & Jackfruit ExtractOryza sativa · Artocarpus
Traditional botanical brighteners, carried in a hydrating propanediol base.
The Protocol
How to use it, and what to expect.
Consistency is the variable that decides outcomes. Build the habit first; the biology follows on its own schedule.
1
Morning, on clean skin
A small amount to a dry face and neck before anything else. Vitamin C works best when it reaches skin first, undiluted by an emollient layer.
2
Always follow with SPF
Antioxidants and sunscreen are complementary, not interchangeable. Vitamin C neutralises what gets past the filter. It does not replace it.
3
Build up gradually
Every other morning for the first fortnight. A low-pH serum tingles briefly on application; persistent stinging means slow down.
Week 1–2
Tolerance settles
The initial tingle fades as the barrier adapts. Nothing visible yet — this stage is purely about consistency.
Week 4
Tone begins to even
Melanogenesis inhibition shows first. Diffuse dullness and post-inflammatory marks soften before anything structural moves.
Week 8–12
Texture and firmness
The horizon on which the trials measured significant wrinkle improvement, with new collagen confirmed on biopsy.
Ongoing
Daily protection
Antioxidant benefit works on the day you apply it rather than accumulating — which is the whole argument for using it every morning, indefinitely.
Questions
Before you begin.
Because each solves a different problem. L-ascorbic acid is the most active and the least stable. Magnesium ascorbyl phosphate is pH-neutral and survives conditions that degrade pure ascorbic acid. 3-glyceryl ascorbate converts gradually in the skin, extending delivery. One form means accepting one weakness. Three covers the gaps.
All vitamin C oxidises eventually; the question is how fast. Ferulic acid slows it substantially and the derivatives are inherently more stable than pure ascorbic acid. A gradual deepening from clear to pale straw is normal over the life of the bottle. Distinctly orange means it is time to replace it.
Yes, but separate them by time of day. This serum in the morning, the Ageless Retinol Moisturizer at night. Layering them in one routine tends to cost you tolerance without buying you results.
Yes, lightly. If you need a completely fragrance-free routine, the Lumina PDRN Brightening Serum and the Renew Copper Peptide Moisturizer are both fragrance-free.
