Helloskin vs The Ordinary
The Ordinary's Azelaic Acid Suspension 10% is the serum everyone starts with — and at under $20 it's a genuine bargain. But it's exactly 10% (half our dose), it's a silicone suspension — undissolved azelaic particles in a dimethicone base that can grit and pill under makeup — and there's no niacinamide behind it. We run a true, dissolved 20% azelaic with 10% Niacinamide and a salicylic-acid assist. Here's the breakdown — no spin, just chemistry.
Half the azelaic, suspended not dissolved, and nothing else in the bottle — but a genuinely great price.
The two formulas, side by side.
Every spec that matters — including the row where The Ordinary genuinely wins: price.
A suspension, or a solution?
Azelaic acid barely dissolves in water, so brands have two honest choices: dissolve it properly, or suspend the raw particles. The Ordinary suspends 10% in a silicone base — which is why it can feel gritty and pill under makeup or sunscreen. We dissolve a full 20% into a light Undecane/Tridecane serum that spreads clean.
suspended in silicone
Isodecyl Neopentanoate and Dimethicone carry undissolved azelaic particles (azelaic sits 4th, with Polysilicone-11). It works, but the base is why users report grit, white cast and pilling — and it's only 10%, with no other actives.
true, dissolved
A full 20% azelaic acid dissolved into a light serum base, with 10% Niacinamide, a salicylic-acid assist and antioxidant protection — prescription-level strength that still layers cleanly.
Credit where it's due: The Ordinary's suspension is cheap and effective, and some people never mind the texture. But half the dose, in a base that grits, with nothing else in it, is a starter — not the strongest option on the shelf.
What each label actually delivers.
Both declare their azelaic. Here's the rest of the picture.
The Ordinary gives you 10% azelaic and Vitamin E for under $20 — real value. But we give you double the azelaic, dissolved not suspended, plus Niacinamide and a BHA, for $39.99. More active, better delivered.
Prescription-strength azelaic, without the prescription.
Dermatologists prescribe azelaic acid at 15–20% (Skinoren is 20%, Finacea 15%). Most over-the-counter serums stop at 10% — half. We run a full, true 20%, on the shelf, no script.
True azelaic acid — the prescription ceiling
The same 20% concentration a dermatologist prescribes as Skinoren, in a cosmetic serum you can just buy — paired with 10% Niacinamide and a salicylic-acid (BHA) assist.
Dissolved, not suspended or "derivative"
Real azelaic acid, carried in a light Undecane/Tridecane serum base that spreads clean — not a gritty silicone suspension, and not a milder Potassium Azeloyl Diglycinate stand-in.
Azelaic acid is dose-dependent and a higher percentage is stronger — it can also be more active on sensitive or rosacea-prone skin, so patch-test and build up slowly. Not medical advice; azelaic acid at these levels is a cosmetic ingredient here, not a substitute for prescribed treatment.
All 15 categories. Scored fairly.
Helloskin wins 12, ties 1, cedes 2. The Ordinary genuinely wins on price and being fragrance-free — credit there. On dose, form and everything else in the bottle, we win.
Every ingredient. Both labels, side by side.
The Ordinary's base is silicone-led (Isodecyl Neopentanoate, Dimethicone, Polysilicone-11) — which is what suspends the azelaic and what can grit. Vitamin E is the only extra active.
What The Ordinary gets right.
Genuinely a lot for the money. At $19.40 for 30ml, The Ordinary's Azelaic Acid Suspension 10% is the cheapest credible way into azelaic, it's fragrance-free (better for the most reactive skin), and the 10% dose is a sensible starting strength. For a first-ever azelaic, on a budget, it's a fair pick.
Where we pull ahead is dose, delivery and everything else. Theirs is 10% suspended in a silicone base that many users find grits, casts white or pills under makeup; ours is a true 20% dissolved into a light serum. Theirs is azelaic and Vitamin E and nothing more; ours adds 10% Niacinamide, a salicylic-acid assist and Ferulic Acid. Double the azelaic, better delivered, in a fuller formula — for $39.99. The one thing to weigh: our serum contains fragrance, so the most sensitive skin may prefer theirs.
What people actually ask.
Is 20% azelaic better than The Ordinary's 10%?
What does 'suspension' mean, and why does it matter?
The Ordinary is much cheaper — why pay more?
Which should I choose?
