Mind this
- A morning step, under sunscreen
- Add it on its own for a week or two, so you know what your skin is answering to
Maya's readThe Ordinary Vitamin C Suspension 23% + HA Spheres 2% is a serum built around Vitamin C (LAA), Squalane and Isononyl Isononanoate. It leans strongest on hydration, barrier repair, brightening / tone. Best suited to normal, oily and combo skin. Nothing in it we'd flag for most people.

€0.04 an applicationabout 150 uses from 30 ml
a usual amount, not a measured dose: 3-5 drops, about 0.2 ml; from €6 as read in September 2026 and a 30 ml pack.
how this is counted
About €0.04 an application, about 150 uses from 30 ml.
- a convention: no trial has measured a serum dose
- Measured or assumed: the rule, and the dose table
Skip it if you already own something similar: it's a solid, honest basic rather than a must-have upgrade.
Fragrance, texture and film: what the label says of its feel
- fragrance-free by the label: no parfum, none of the 26
- a serum in a tube
- no film-former or occlusive named on the label
- no silicone on the label

Fungal acne: what on this label feeds the yeast (Malassezia)
the yeast: Malassezia furfur, globosa, restricta
Nothing on this label was measured to feed Malassezia; 1 is inferred to from the chain length (ethylhexyl palmitate).
Each result is a pure ingredient on a lab dish, never this product on skin.
where this comes from
- ethylhexyl palmitateInferred from the chain length: The strongest growth was observed in the presence of natural oils and waxes, primary alcohols, as well in the presence of fatty acid esters with fatty chain lengths above 12 carbon atoms.DOI 10.3390/cosmetics6030045
What does it do? What its ingredients deliver
How it feels A light, fast-absorbing texture that layers cleanly under the rest of your routine, with no greasy film. (estimated from the formula)
Key ingredients: what in it does the work
Potent antioxidant and brightening acid form of vitamin C; very effective at low pH but can be irritating on sensitive skin.
Vitamin C (LAA): Give it eight to twelve weeks, and possibly less: that is simply when it was measured.
how it was measured
Measured on investigator-graded photodamage on the treated half-face (fine wrinkling, roughness, tone); measured at the trial's end, so possibly sooner.PMID 10522500PMID 11896774
Stable, lightweight emollient that mimics skin’s natural lipids and supports barrier without heavy greasiness for most skin types.
Very light synthetic ester that gives high slip and a silky feel, often used in sunscreens and serums.
Water-binding molecule that increases hydration; works best under occlusive/emollient layers to reduce evaporation.
Plant-derived ester emollient that mimics the lightweight, silky feel of volatile silicones with good compatibility for sensitive and acne-prone skin.
Light ester emollient that improves slip and reduces greasiness. Acne prone and Malassezia prone skin may not tolerate it well.
What only this label says
why
Position 1 of 15 on the label as printed; compared with the 111 other labels in the catalogue that carry a vitamin.
Vitamin C (LAA) is the base: no water in this formula, one of 12 in our catalogue.
why
The first ingredient on the label, and no Aqua, Water or Eau anywhere in the list; 12 of 162 labels in the catalogue list no water.
≈ €0.20/ml, below the median serum in our catalogue (€0.57/ml).
why
~€6 for 30 ml, checked September 2026; the median of the 47 serums in the catalogue with a known size.
Vitamin C (LAA) is declared at 23%: above the 5% the trials used.
why
The floor is 5%: a 5% L-ascorbic acid cream beat its excipient on a dermatologist global score, silicone-replica microrelief and elastic-fibre ultrastructure over 6 months on the neck and forearms of photoaged women (Humbert 2003, double-blind; the abstract gives no headcount). Declared on the name.
Shares 2 of its 6 known actives with Medik8 Crystal Retinal 6: the closest formula we have.
why
Actives our base knows on both labels: Squalane and Hyaluronic acid.
Vitamin C (LAA) is light-sensitive: the packaging matters more than the percentage.
why
photolability = yes in our base: The rate of oxidative degradation in the dark is about seventy times slower than that observed in the presence of light. (PMID:21735345(abstract)).

Does it expire? Light, air and the pack
a tube and one light-sensitive active: the packaging is doing work here.
where this comes from
The pack form is read off the packshot; the light-sensitive actives are the base's photostability rows, sourced on each glossary page; the period after opening (not printed) is read off the maker's page, never a reseller's. Catalogue checked September 2026.
How to use it, and when
In the morning, under sunscreen: vitamin C pairs well with SPF and helps defend against daytime damage.
Where in your skin it works
1 of its 6 placed actives acts below the dead surface layer, 5 on or in it: the same cross-section as our 500 dalton page, with this formula's actives on the layer each one works on. Depth is the anatomy's, never an ingredient's.

How it compares with the average serum
It scores higher than the median serum on brightening.
It gives up ground on hydration and oil control.
A median, not an average: one unusual formula should not move the middle. The numbers are the same 0 to 10 reads the comparison pages use.

What the 3D scene shows
The scene shows The Ordinary Vitamin C Suspension 23% + HA Spheres 2% beside a cross-section of skin, with 3 of its ingredients drawn at the layer each one acts on and at one shared molecular scale: Isononyl Isononanoate and Squalane in the stratum corneum, the dead outer layer where most skincare works; Vitamin C (LAA) in the dermis, where collagen and elastin sit. Depths come from the same sourced layer data as the rest of this site, and any ingredient whose layer is not established is left out rather than guessed.
