Helloskin vs Facetheory
Facetheory's Blemicalm 15% is the closest competitor here on strength — a true 15% azelaic (most rivals stop at 10%), cushioned with colloidal oat, aloe, rosehip and green tea, vegan and thoughtfully clean. Real credit for the dose and the soothing. But it's still short of our 20%, it has no niacinamide, and its "BHA" is an emollient, not an exfoliant. Here's the breakdown — no spin, just chemistry.
The closest on strength at 15%, and genuinely soothing — but still short of 20%, with no niacinamide.
The two formulas, side by side.
Every spec that matters — including where Facetheory genuinely wins: soothing botanicals and a nourishing base.
15% soothed, or 20% with niacinamide?
Facetheory did something most brands don't — pushed past 10% to a true 15%, and cushioned it with oat, aloe and rosehip. It's the closest serum here to our strength, and gentler with it. We go one step further to a true 20% and add a real 10% niacinamide and an active BHA.
soothed & nourishing
A true 15% azelaic with colloidal oat, aloe, rosehip seed oil and green tea — vegan, clean and genuinely soothing. Stronger than most rivals, but below 20%, with no niacinamide and only an emollient salicylate, not an active BHA.
stronger + niacinamide
A true 20% azelaic with 10% Niacinamide, an active salicylic-acid assist and Ferulic Acid + Vitamin E — the higher dose, plus a fuller active line-up.
Credit where it's due: 15% is a genuinely strong, well-cushioned dose, and the oat-rosehip base is more nourishing and lower-fragrance than ours. We answer with a higher 20%, a real niacinamide and an active BHA.
What each label delivers.
Closest on azelaic; different on the rest.
Facetheory is the closest on azelaic — 15% vs our 20% — and more soothing. But we're higher-dose and add a real 10% niacinamide and an active BHA it doesn't have.
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 9, ties 3, cedes 3. Facetheory genuinely wins on soothing botanicals, a nourishing oil base and being lower-fragrance/vegan. We win on dose, niacinamide and a real BHA.
Every ingredient. Both labels, side by side.
Facetheory's list is clean and soothing: 15% azelaic (4th), colloidal oat, rosehip seed oil, aloe and green tea. Note Butyloctyl Salicylate is an emollient, not an active BHA — and there's no niacinamide.
What Facetheory gets right.
A fair amount. Facetheory pushed to a true 15% azelaic when almost everyone else stops at 10% — the closest serum here to our strength — and cushioned it well with colloidal oat, aloe, rosehip seed oil and green tea. It's vegan, lower-fragrance than ours, and nourishing. If you want a strong-but-soothing azelaic with a botanical, clean-beauty leaning, it's a genuinely good serum.
Where we pull ahead is the last step of dose and the actives around it. Ours is a true 20% versus their 15%; we add a real 10% niacinamide (they have none) and an active salicylic acid, where their Butyloctyl Salicylate is an emollient, not an exfoliant. They win soothing, a nourishing oil base and lower fragrance; we win dose, niacinamide and a true BHA.
What people actually ask.
Is 20% much stronger than Facetheory's 15%?
Does Facetheory have a BHA like Helloskin?
Facetheory is gentler — does that matter?
Which should I choose?
