Buy the Niacinamide 10% + Zinc 1% first. It is the cheapest genuinely useful serum in the range, the active is well evidenced at the strength printed on the bottle, and it layers into a routine without rearranging it. It is also the budget pick — the cheapest product on this page is the one that wins it, and rather than invent a split we will say so plainly. If your skin flushes easily, start at number two instead and come back to the niacinamide later.
One framing before the ranking, because it is the whole reason this page can be written honestly. Most skincare brands sell you a name — a "brightening complex", a "peptide blend" — and you have no way to know how much of anything is in the bottle. The Ordinary publishes the concentration in the product name. That is why this site cites their own product pages as a primary source elsewhere: on this one brand, the dose is checkable. So that is what the ranking below is built on. Every pick is scored on whether the stated number is meaningful, whether the evidence supports that molecule at that dose, and whether the base it arrives in is wearable — because the base is where this range is genuinely weakest.
The failure mode this page is trying to prevent
The catalogue is enormous and the prices are low, which produces a predictable outcome: a basket of six actives bought at once, applied on the same night, followed three weeks later by a stinging, flaking face and the conclusion that "The Ordinary broke me out". Almost always it was the stack, not the brand.
So the ranking below is deliberately an acquisition order, not a shopping list. Buy number one. Use it for three weeks. Then add the next thing you actually have a reason for. Two actives is a routine; five is an experiment with no control. If you want the sequencing in full, our skincare routine order guide has it, and how long to wait between steps answers the question this brand generates more than any other.
How we ranked these
- Label transparency — does the name give you a named molecule at a stated percentage, or a blend you cannot audit? The Ordinary usually does the former, and the products where it does not are marked down for it.
- Evidence at that dose — is there published support for this ingredient at roughly this strength, applied topically? A real number attached to a thin ingredient is still a thin ingredient.
- The base— the silicone suspensions, the squalane oils and the tacky water-gels are the range's weak point, and the reason people abandon products that were working. Texture is not vanity; it predicts whether the bottle gets finished.
- Routine fit — does it belong in a routine most people should actually be running, or is it a sixth step for someone who has not got the first three right?
- Value — against the same molecule at the same dose from anyone else.
Scores are judgments from documented research — published concentrations, decoded ingredient lists and aggregated owner reports. They are not lab measurements, and how we reviewsays so in those words. Every price in the table below comes from the live price layer and carries its own "as of" date; if a product shows no number, we have no verified live price for it right now and are showing none rather than a stale one.
Three in the range we would not start with
A brand roundup that only praises is not a roundup. These three are all popular, and all three are products we would steer a new buyer away from.
- AHA 30% + BHA 2% Peeling Solution. The most photographed product the brand makes and the one that causes the most damage. A 30% acid blend left on for ten minutes is a genuine chemical exfoliation, not a mask, and the failure mode is a compromised barrier rather than a bad result. It has its place for someone with established acid tolerance and none at all for a beginner. Our full review of the peeling solution goes through the protocol and the contraindications properly.
- Multi-Peptide + Copper Peptides 1%.The most expensive serum in the range by a wide margin, and the one where the stated percentage buys you the least certainty. Copper peptides have an interesting mechanistic story and thin topical outcome data, and paying several times the price of the niacinamide for that trade is the one place this brand's value argument breaks down. Our peptides versus retinol page explains why a retinoid is the better use of the same money.
- Any of the squalane-based oils as a first active. The Retinol 0.2% in Squalane is a perfectly reasonable product and it has its own review here, but an oil base is the hardest format to layer and the easiest to over-apply. If you want a retinoid from this brand, the emulsion at number three is the better-made object.
The step you have to buy somewhere else
Sunscreen. Our registry carries no Ordinary sunscreen and our face sunscreen roundup ranks none, which matters more than any ranking on this page: a daily SPF does more for the things people buy actives for — tone, texture, lines — than every serum above combined. If you are building a routine out of this brand, buy the sunscreen elsewhere and treat it as step one rather than step six. The same applies to a proper occlusive moisturizer; the HA serum at number two is a humectant and it needs a cream over it.
Which one for which problem
| What you came here for | Buy | Why that one |
|---|
| Oily skin, visible pores, midday shine | Niacinamide 10% + Zinc 1% | The only pick with a felt effect on sebum, at the top of the useful dose range |
| Breakouts plus the red marks they leave | Azelaic Acid Suspension 10% | One product working both problems, at full over-the-counter strength |
| Dark spots and uneven tone | Alpha Arbutin 2% + HA | Interferes with pigment production and does not sensitize skin to sun |
| Fine lines, texture, long-term aging | Retinal 0.2% Emulsion | The most potent retinoid in the range, in the best base in the range |
| Dullness, antioxidant protection | Ascorbyl Glucoside Solution 12% | One named vitamin C derivative at one stated dose, with no sting |
| Rough texture, flaking, dry skin | Lactic Acid 5% + HA | A mild, real AHA dose - not the 30% peel |
| Tightness, dehydration, winter skin | Hyaluronic Acid 2% + B5 | No adjustment period and nothing to react to, as long as you seal it |
What a published percentage does and does not tell you
This is the honest limit of the whole premise. A stated concentration tells you the dose. It does not tell you the delivery: the pH of an acid formula decides how much of it is in the free acid form, the base decides how much stays on the skin rather than rolling off under sunscreen, and the packaging decides how much is still intact in week six. The Ordinary publishes the first number and, like everyone else, not the rest.
That is precisely where the range gets beaten, and it is worth being specific rather than loyal: where a competitor wins against these products, it almost always wins on the base and not on the chemistry. Our alternatives to The Ordinary page works through those swaps active by active, and reaches a conclusion worth repeating here — five of six swaps cost more, and what the extra money buys is texture. Texture is a legitimate thing to pay for, because adherence predicts outcomes. It is just not a potency upgrade, and nobody should pretend it is.
Combining them without wrecking your face
Four rules that cover nearly every mistake we see with this brand:
- One new active at a time, three weeks apart. If two things go on in the same week and your skin reacts, you have learned nothing about either.
- Acids and retinoids go on different nights. Not because of a chemical interaction myth, but because both increase irritation and stacking them is how barriers break. See skin cycling for a schedule that already does this.
- Direct acids and pure L-ascorbic acid do not belong in the same layer. The brand's own guidance says so. The ascorbyl glucoside above is the exception and that is part of why it ranks.
- Seal every water-light serum. Every pick on this page except the azelaic suspension is thin and water-based. Without a moisturizer over the top you lose most of the benefit and gain the tackiness.
Is The Ordinary good, or just cheap?
Both, and it is worth separating them. Cheap is the headline; the substantive thing is disclosure. Being told that you are buying 10% niacinamide, or 10% free azelaic acid, or 0.2% retinaldehyde, lets you compare against published research instead of against marketing copy — and lets you notice when a product costing five times more is vaguer about what is in it. That is a real contribution to the category, and it is why this range keeps showing up on this site's roundups.
The limits are equally real. The bases are the range's weak point, the catalogue structure encourages over-buying, the brand sells no sunscreen we would rank, and DECIEM — the company behind it — is part of The Estee Lauder Companies, which is worth knowing if brand ownership factors into your decisions. None of that changes the ranking. It just means the right way to shop this brand is three products deep, not fifteen.
