The Ordinary vs The INKEY List: clinical actives vs accessible clinical

The Ordinary vs The INKEY List is a concentration-and-conflict decision, not a moisturizer decision. The Ordinary on theordinary.com sells single actives with the percentage in the name, a pH band, and a “do not use with” list. The INKEY List on theinkeylist.com sells the same families — niacinamide, hyaluronic acid, a starter retinoid, a water cream — with the percentage in the ingredient block and a 60-day satisfaction path that does not require you to mail the bottle back. Choose The Ordinary when you want the conflict table and a 365-day return on a bottle that is still at least half full, and you will pay the postage. Choose The INKEY List when you want a 30 ml serum with a how-to-layer FAQ, and you accept that the US help centre does not take the product back. StoreAtlas files both as stores on the beauty hub and the skincare tag. This note is not a Best of ranking.

The Ordinary also sits on the skin-first kits job. Other shopping tasks already filed live on the jobs index. Both brands also live as files in the store directory.

The Ordinary vs Drunk Elephant is the live compare if the other bottle is a luxury acid. This note stays on these two clinical shelves. Use beauty storefront notes, how to read a Shopify product page, and returns before you buy. The conflict line and the return line are the two fields that change the order.

What the percentages actually are

The Ordinary is a DECIEM brand. The returns header says DECIEM, and the site calls itself a DECIEM project. On the US store, Niacinamide 10% + Zinc 1% comes in 30 ml and 60 ml. During a sitewide offer the 30 ml was printed as reduced from $6.00. It is a water-based serum, pH 5.00–6.50, and the page marks it oil-free, alcohol-free, silicone-free, vegan, gluten-free, and cruelty-free. The conflict line is the purchase: do not use with direct vitamin C or indirect vitamin C. The FAQ says to put niacinamide and vitamin C in separate routines.

Hyaluronic Acid 2% + B5 with ceramides is 30 ml and 60 ml. The 30 ml was reduced from $9.90 on that same offer. The page calls it a second-generation hyaluronic acid serum: five forms of HA, ceramides, pro-vitamin B5, pH 6.0–7.5. No “do not use with” block was on that PDP. Glycolic Acid 7% Exfoliating Toner is 100 ml and 240 ml, the 100 ml reduced from $9.00, pH 3.5–3.9. It says not to use it on sensitive, peeling, or compromised skin. The sunburn alert says AHAs can increase sun sensitivity, so use sunscreen and limit sun for a week after. The do-not-use list on that page includes copper peptides, direct vitamin C, direct acids, retinoids, peptides, and several named Ordinary formulas. Avoid the eye contour.

Retinal 0.2% Emulsion is 15 ml, reduced from $14.90, and the retinoid category calls it the highest-strength retinoid. It is for people who already use retinoids. Beginners are pointed at Granactive Retinoid 2% Emulsion or Retinol 0.2% in Squalane. Use it in the evening only, with sunscreen the next day. The conflict list includes copper peptides, direct acids, direct vitamin C, and other retinoids. The FAQ says to avoid Granactive Retinoid and retinol formulas when pregnant or breastfeeding. Granactive retinoids are not sold in Canada, per the FAQ. Some retinol and Granactive formulas say to refrigerate after opening. Read that line on the bottle you buy. The offer prices above were a reduction on the US pages. The “reduced from” number is the list price printed next to them. Checkout can move.

The INKEY List explains the same actives in blocks: what you get, why it works, how it feels, when to use, then key claims and a long FAQ. The 10% Niacinamide Serum is $13 for 30 ml. Copy says it visibly reduces excess oil, breakouts, and the look of pores. An FAQ also says the formula includes 1% hyaluronic acid. Printed pH is 6.09. The page calls it fragrance-free and suitable in pregnancy and while breastfeeding. It is not vegan: the FAQ names an egg-derived phospholipid. The heads-up says to avoid high-strength vitamin C and exfoliating acids, and that it is safe with their 15% vitamin C plus EGF serum. A separate FAQ says it can be layered with glycolic or salicylic if you introduce them slowly, and with retinol if niacinamide goes first. Those two sentences are both on the brand’s pages. Read both before you build a routine from one of them.

Hyaluronic Acid Serum is $13 for 30 ml, with 60 ml and 100 ml also listed. It is 2% multi-molecular HA plus Matrixyl 3000, pH 6.21, applied to damp skin, and the page says it works with retinoids and AHAs. Omega Water Cream is $15 for 50 ml: oil-free, for oily and acne-prone skin, 0.2% ceramide complex, 5% niacinamide, 5% glycerin, 3% betaine, pH 5.0, non-comedogenic, and described as fine with retinol and AHAs. Starter Retinol Serum is $15 for 30 ml. The PDP says the original INKEY retinol was discontinued. This one is 1% Granactive Pro+ (also written as Granactive Retinoid Pro Plus) and 0.01% retinal, plus 0.5% Amisol Trio and 0.2% SymRelief. Use it at night, two or three nights to start, then SPF. The page says not to use retinoids in the morning, and not to use retinol, retinal, or vitamin A in pregnancy without a doctor. A separate Advanced Retinal is 0.2% retinal. That is the strength to compare with The Ordinary’s Retinal 0.2% Emulsion, not the starter.

The Ordinary’s niacinamide is 10% plus 1% zinc, in a 30 ml that lists from $6, with a hard conflict against vitamin C. The INKEY List’s niacinamide is 10% plus 1% HA, at $13 for 30 ml, with a softer and partly conflicting acid note. The Ordinary’s high retinoid is 0.2% retinal in 15 ml. The INKEY List’s starter is 0.01% retinal plus a granactive retinoid. Same aisle. Different dose.

Shipping thresholds and who takes the bottle back

The Ordinary’s US FAQ table lists standard shipping at $4.99, free over $25. The table also prints Canada, the UK, and Europe at 4.99 in local currency, free over 25, and says the numbers can change. US orders ship DHL via USPS. No PO boxes or military addresses in the US. Duties are included for EU countries and not for every other region. PDPs repeat free shipping over 25 USD.

The return policy is 365 days from the invoice date, for DECIEM site and DECIEM store purchases. The bottle must be at least 50% full. You pay the postage. DECIEM does not provide a label and does not pay tracking. Refunds go to the original payment, aimed at within 12 business days of the warehouse receiving the goods. No store credit and no exchanges. Shipping fees and anything marked final sale are not refunded. Sets come back complete. Retailer purchases go back to that retailer. Mail-back addresses are printed for the US, Canada, Australia, and the UK and EU.

The INKEY List’s US help centre and the hero PDPs say standard tracked shipping from $7.95, 2–5 business days, free over $40. Most states are $7.95. Alaska, Arizona, California, Hawaii, Idaho, Nevada, Oregon, and Washington are $8.95. Orders ship from Ohio. The help centre says no tariffs on US orders, and no shipping to Guam, Puerto Rico, or the US Virgin Islands. An older shipping-policy page on the same site still prints US shipping at $5.95 and free over $35. The help centre and the product pages are the numbers to trust until that older page is gone. Screenshot the one at checkout.

Returns are the sharp difference. The help centre says they do not currently accept returns, and that they cannot accept a product back once you have received it. Since May 2022 there is a 60-day satisfaction guarantee, only for www.theinkeylist.com. If you are not satisfied, they help you find an alternative or refund. You must have used at least one product. You do not send the bottle back. The limit is three claims a year and one claim per product, inside 60 days of receipt. They can refuse a claim if later advice is ignored. Retailer purchases go back to the retailer. Returns before you buy is this paragraph. The Ordinary will take a half-full bottle for 365 days if you pay postage. The INKEY List will not take the bottle, and may refund inside 60 days without a return.
