Vitamin C
3-O-Ethyl Ascorbic Acid · Ascorbyl Tetraisopalmitate · Ascorbic Acid · Ascorbyl Glucoside
Vitamin C is ascorbic acid — powerful, and notoriously unstable in heat, light and air. SKEYNDOR has formulated it since 1997 and now works with four forms across the range, choosing each for its job: fast-acting ethyl ascorbic acid, slow-release ascorbyl tetraisopalmitate — a form shown to deliver 700% greater cellular absorption than pure ascorbic acid — pure ascorbic acid sealed under nitrogen in ampoules, and gentle ascorbyl glucoside for daily creams.
The work it performs
What it does
Neutralises the free radicals generated by city pollution and UV exposure — the daily defence the whole range is built on.
Visibly brightens and adds luminosity — the benefit professionals emphasise first for tired, city-dulled skin.
Acts on melanin formation, softening the look of superficial pigmentation and age spots over time.
Ascorbic acid is the signal skin cells receive to begin producing collagen — every step of its formation depends on vitamin C.
The two-derivative serum acts directly and rapidly while the oil-soluble form releases gradually — radiance now, and through the day.

Forms & strengths
In the cabin
The Antiox Brightening program opens with an ellagic-acid booster — shown to raise the skin cells' vitamin C absorption by 41% — before the 25% professional concentrate, super-fruit boosters, a cooling mask and jade Gua Sha ritual.
The Power C+ treatmentHandle with care
Build up rather than diving in: start with the creams, add the serum once daily, then move to morning and night over a week or two. Never stack two concentrates in the same application — one in the morning and one at night is the rule. Rest it if skin is inflamed, sunburned or highly reactive, and expect honesty from it: it softens superficial spots, not deep or hormonal pigmentation.
Pairs well with
- Pomegranate & AçaíThe super fruits — one reinforces the brightening effect, the other defends collagen, lifting the serum to 17.5% total antioxidant.
- Vitamin EThe classic antioxidant partnership, formulated together in the Energising Cream.
- Pure RetinolThe day/night split for photo-ageing: vitamin C defends by day, retinol renews by night.
