Helloskin vs ANUA
ANUA's Azelaic Acid 10 Hyaluron serum is a beautiful, gentle K-beauty formula — a true 10% azelaic wrapped in a full centella (cica) complex, ceramide, hyaluronic acid and beta-glucan. For calming and barrier repair it's genuinely lovely. But it's 10% (half our dose), and its focus is soothing, not strength. We run a true 20% with 10% Niacinamide. Here's the breakdown — no spin, just chemistry.
One of the gentlest, most soothing azelaic serums going — but it's built for comfort at 10%, not strength.
The two formulas, side by side.
Every spec that matters — including the rows where ANUA's soothing, barrier-repair focus genuinely wins.
Soothing at 10%, or strength at 20%?
ANUA optimised for calm: a true 10% azelaic buried in one of the most complete soothing-and-barrier rosters in K-beauty — centella, ceramide, beta-glucan, panthenol. It's a wonderful serum for reactive, red skin. Our brief was different: a true 20% for maximum azelaic effect, with niacinamide.
wrapped in cica + ceramide
A true 10% azelaic surrounded by a full centella complex, ceramide NP, hyaluronic acid, beta-glucan and panthenol. One of the gentlest, most barrier-supportive azelaics available — but half the dose, and soothing-led.
strength-led
A true 20% azelaic with 10% Niacinamide, a real salicylic-acid assist and antioxidant protection — double the azelaic, tuned for results on tone, texture and blemishes.
Credit where it's due: for sensitive, compromised or rosacea-prone skin, ANUA's cica-and-ceramide base is genuinely excellent, and it's cheaper and fragrance-free. We trade that cushioning for double the azelaic and a 10% niacinamide.
What each label delivers.
Both are true azelaic. Dose and focus differ.
ANUA wins soothing, barrier repair and price; we win azelaic dose, niacinamide and a real BHA. Double the azelaic vs the gentlest cica base — different jobs, honestly.
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 8, ties 3, cedes 4. ANUA genuinely wins on cica soothing, ceramide barrier repair, gentleness and price — a beautiful sensitive-skin serum. We win on azelaic dose and actives.
Every ingredient. Both labels, side by side.
ANUA's list is a soothing masterclass: 10% azelaic (2nd), then a full centella complex, ceramide NP, beta-glucan, aloe and hyaluronic acid. Niacinamide is present but low. Half our azelaic, far more cica.
What ANUA gets right.
Genuinely a lot. ANUA's serum is a true 10% azelaic in one of the most complete soothing bases in K-beauty — a full centella complex (madecassoside, asiaticoside), ceramide NP for the barrier, hyaluronic acid, beta-glucan, aloe and panthenol — gentle, fragrance-free, and cheaper at around $29.50. For sensitive, red, compromised or rosacea-prone skin, it's a beautiful choice, arguably kinder than ours.
Where we pull ahead is azelaic itself. Theirs is 10%; ours is a true 20% — double — with 10% Niacinamide (theirs is a trace), a real salicylic acid rather than the gentler betaine salicylate, and Ferulic Acid + Vitamin E. ANUA is the gentler, more barrier-focused serum; we're the stronger, results-led one. The honest trade-offs: they're cheaper, fragrance-free and far more soothing.
What people actually ask.
Is ANUA real azelaic acid?
I have sensitive or rosacea-prone skin — which is better?
Does ANUA have niacinamide like Helloskin?
Which should I choose?
How we stack up against the rest.
Every comparison is the same honest, ingredient-level breakdown. No marketing, just chemistry.
Helloskin vs The Ordinary
A cult 10% azelaic — but a silicone suspension that can grit and pill, with no niacinamide.
Helloskin vs Azclear
The AU pharmacy 20% azelaic — same strength as ours, but a bare medicated lotion with no niacinamide or BHA.
Helloskin vs Paula's Choice
The most elegant, fragrance-free 10% azelaic + 0.5% SA — beautifully soothing, but half the dose and ~$52.
Helloskin vs Naturium
A gentle serum whose "azelaic" is Potassium Azeloyl Diglycinate — a derivative, not the real acid.
Helloskin vs Facetheory
The closest on strength — a true 15% azelaic with oat and rosehip — but below 20%, with no niacinamide.
Helloskin vs The INKEY List
A tidy, fragrance-free 10% azelaic with a redness-tint — but half the dose, no niacinamide or BHA.
Helloskin vs NINELESS
Astonishing-value true 10% azelaic with cica and snail — but half the dose across a 30+ ingredient list.
Helloskin vs Geek & Gorgeous
Sold as "20%" but it's a Potassium Azeloyl Diglycinate derivative (~6% azelaic-equivalent), not the real acid.
Double the azelaic, built for results.
A true 20% azelaic with 10% Niacinamide and a salicylic-acid assist — twice the dose of the gentle 10% cica serums. Australian-made. $39.99.
