The verdict
The most usable budget actives brand. Everything The Ordinary does on price and concentration labelling, with the added benefit of an education layer that actually tells you what to do. Oat Cleansing Balm and Succinic Acid are both excellent.
What works
- Every product page and pack explains what the ingredient is, what it does and when to use it
- Oat Cleansing Balm is one of the best cleansing balms at any price, at around $13
- Succinic Acid Blemish Treatment is a genuinely effective spot treatment nobody else makes
- Concentrations published throughout, with sensible starter and advanced routing
What does not
- Some formulas are cosmetically less elegant than the price-comparable competition
- The catalogue has expanded fast and lost some of its original clarity
- Vitamin C options are weaker than the rest of the actives range
- Availability outside the UK and US retail partners is patchy
The INKEY List was founded in London in 2018 by Colette Laxton and Mark Curry, both ex-Boots, with a proposition that reads as a direct response to The Ordinary: same idea, same price, but we will explain it to you.
That sounds like a small difference. In practice it is the difference between a brand you can shop and one you have to research first.
The education layer
Pick up an INKEY List product and the pack tells you the ingredient, the concentration, what it does, who it is for, when in your routine to use it and — critically — what not to use it with. The website expands that with a "Beginner / Intermediate / Advanced" routing and an ingredient encyclopaedia.
None of that is a formulation achievement. All of it is the reason a person with congested, irritated skin can walk away with the right product rather than an anhydrous vitamin C suspension they will hate.
Transparency scores 9.0, joint-highest in this review alongside Paula's Choice, and it is earned on this rather than on anything exotic.
The products worth buying
Oat Cleansing Balm is the standout and one of the best products in this whole review at any price. It is an oat-oil-based balm cleanser that melts makeup and sunscreen, emulsifies cleanly with water, and does not leave the greasy film most cheap balms do. At around $13 for 150 ml it undercuts prestige balm cleansers by a factor of four and is not meaningfully worse.
Succinic Acid Blemish Treatment is the most interesting thing the brand makes. Succinic acid is an underused active with antibacterial and anti-inflammatory activity, and it works on the kind of inflamed spot that salicylic acid does not touch. Nobody else sells it at this price. Around $11.
Niacinamide 10% is a straightforward, well-made serum. Retinol Serum is a stable encapsulated retinol with a published strength and a sensible starter routine. Hyaluronic Acid Serum is fine and, like all hyaluronic serums, unremarkable.
Polyglutamic Acid Serum is worth knowing: PGA is a humectant that holds substantially more water than hyaluronic acid and leaves a slightly filmy finish that works well under makeup.
Against The Ordinary
These two are constantly compared and the comparison is straightforward.
The Ordinary is cheaper on several items, has a deeper actives catalogue, and offers a few things INKEY does not — azelaic acid at 10% being the clearest.
The INKEY List has better cleansers, a better education layer, and formulas that are more often cosmetically pleasant. Its Oat Cleansing Balm has no equivalent in The Ordinary's range.
For a beginner, INKEY. For someone who knows exactly which molecule they want and at what percentage, The Ordinary. Most people would be well served owning products from both.
Where it is weaker
Vitamin C. The INKEY List's options — a 15% vitamin C serum and a C-50 blend — are competent and are not the reason to shop here. If vitamin C is your priority, buy it elsewhere.
The catalogue has also grown considerably since 2018 and some of the original clarity has gone with it. There are now several overlapping hydrators and more than one retinoid option, and the routing guidance is working harder than it used to.
A routine that costs under $50
Because this is the brand we would send a beginner to, here is what that actually looks like.
Morning: Oat Cleansing Balm or a plain gentle cleanser, Niacinamide 10%, moisturiser, sunscreen from somewhere else. Evening: cleansing balm to remove sunscreen and makeup, a gentle second cleanse, then either the Retinol Serum or nothing, then moisturiser.
That is four INKEY products, roughly $50, and it covers the three things that actually change skin over time: cleansing without stripping, one well-chosen active, and daily sun protection.
What to add only if you have a specific problem: Succinic Acid for inflamed spots, Polyglutamic Acid if your skin stays dehydrated, Beta Hydroxy Acid if you are congested. What not to add: anything because it appeared on your feed. The most common mistake we see is a routine with four actives fighting each other, and the second most common is starting three new products in the same week so that when something reacts you cannot tell what caused it.
Introduce one product at a time, a fortnight apart. That advice is free and it is worth more than most of what is in this review.
Price
$9 to $30, with most of the range under $16. Value scores 9.5 — a complete, genuinely effective routine from this brand costs about $50, and it will outperform a great many that cost ten times as much.
The verdict
Buy the Oat Cleansing Balm. Buy Succinic Acid if you get inflamed spots. Add Niacinamide 10% and the Retinol Serum if you want actives, and follow the routing on the pack.
This is the brand we would point a nervous beginner at before anything else on this site, and the one most likely to still be in their bathroom in three years.
