The Ordinary Retinol 0.5% in Squalane Review

The short answer

Retinol 0.5% in Squalane is the cheapest way in our shortlist to buy a known amount of retinol: $9.30 for 30 ml, with 0.5% printed on the label.

It is not, by the brand's own account, the gentlest place to start. The Ordinary calls it moderate strength and points first-timers to its 0.2% version. It also has to live in the fridge once opened.

This is a documentation review. We read the product page, usage and safety text, compatibility notes and the US returns policy on October 21, 2026, plus the American Academy of Dermatology's guidance on retinoids. We did not apply the product to anyone's skin.

What this product actually is

It is a water-free serum: retinol dissolved in squalane and other oils, with no water phase. The brand lists the format as anhydrous.

The full ingredient list has eight entries: squalane, caprylic/capric triglyceride, jojoba seed oil, retinol, tomato fruit extract, rosemary leaf extract, hydroxymethoxyphenyl decanone and BHT. No fragrance appears on that list.

The Ordinary positions it as an intermediate step in a three-step range: Retinol 0.2%, 0.5% and 1% in Squalane. The brand says squalane is a moisturizing agent found naturally in skin, included to help skin withstand retinol's drying effects.

Who it is best for, and who should skip it

This is the bottle for a reader who wants a disclosed dose and a low price, and who has some tolerance or patience.

• Normal to dry skin. The brand lists it as suited for dry skin, and an oil base is easier on dry skin than on oily skin.
• Readers who like to know the number. A labelled 0.5% lets you move up to 1% or down to 0.2% within the same range.
• Tight budgets. At $9.30, it is the cheapest bottle in our beginner shortlist by a wide margin.
• Minimalist routines. It pairs with a plain moisturizer such as CeraVe Moisturizing Cream and a daily sunscreen.
• Skip it if you are a complete beginner wanting the softest start. The brand's own advice is the 0.2% first.
• Skip it if your skin is very reactive or red. The AAD notes that people with a lot of redness or inflammation should ask a dermatologist about other options.

The strength question: moderate, by the brand's own description

The Ordinary describes this product as a moderate-strength retinol serum and an intermediate formulation. Its tip on the page is to start with Retinol 0.2% in Squalane and slowly work up to 0.5% and then 1%.

That matters because the American Academy of Dermatology's page on retinoids quotes a dermatologist advising patients to use the least-intense retinoid formula they can find, every other night to start, building up slowly. Otherwise, she says, they end up irritating their skin.

On October 21, 2026, the 0.2% version was listed at $8.10 but showed an Email me when in stock button. The 1% was $9.90 and the brand's newer retinoid alternative, Granactive Retinoid 2% Emulsion, was $12.10.

So a first-timer buying today faces a choice the brand did not intend: wait for the 0.2%, or start the 0.5% slowly. If you choose the second, the AAD's every-other-night pattern is the conservative way to do it.

Disclosure is the quiet strength here

The AAD page includes a point most shoppers never hear: for over-the-counter products, there is no standard requirement that the percentage of retinol be disclosed on the label or packaging.

The Ordinary prints it in the product name. Of the three retinols in our shortlist, this one and the Paula's Choice 1% disclose a percentage.

The CeraVe resurfacing serum, which goes live on this site in the coming days, does not state one on its product page.

A disclosed percentage does not make a product better. It does make it easier to plan a step-up, compare like with like, and talk to a dermatologist about what you are already using. That is why disclosure counts toward the features score.

What retinol is meant to do, and what to expect

The brand says retinol improves the appearance of fine lines that can arise from a loss of collagen and elastin, while evening the appearance of skin texture and tone. Those are cosmetic appearance claims, worded as such.

The AAD describes retinol as a type of retinoid routinely used to improve uneven skin tone, pigmentation and texture. It says a retinoid product is a good option for someone with mild acne, mild pigmentation irregularities, or mild fine lines and wrinkles.

What neither source promises is speed. The brand warns of irritation, redness and peeling in the early stages while skin builds tolerance. That early phase is the reason both the brand and the AAD stress a slow start.

The brand also states plainly that this product is not a treatment for acne. Readers with active or hormonal acne should see a dermatologist rather than self-treat with a cosmetic retinol.

How to use it, per the brand

The usage text is short and specific, and it is worth following exactly.

• When: in the evening. Apply a few drops to the face.
• Never with other retinoids. The brand says this product must not be used with other retinoids, including retinol or retinoic acid.
• Not in the same routine as: copper peptides, direct acids, direct vitamin C and the brand's Multi-Active Delivery Essence, per its compatibility tool.
• Sun protection by day. The brand notes retinoids can make skin more sensitive to UV.
• Patch test first. The brand advises patch testing on the upper forearm before use.
• Expect early irritation. Redness and peeling are possible, especially around the eyes and mouth, while skin builds tolerance. If irritation occurs, rinse off, stop and consult a physician.
• Not an acne treatment, per the brand's own page.

The fridge rule and what it means for cost

The Ordinary says that once opened, this formulation should be refrigerated and used within a three-month period. That is unusual among the three products we graded, and it shapes the real price.

If you use a few drops every other evening, a 30 ml bottle may not be finished in three months, and the brand's instruction is to stop using it after that period regardless. Our arithmetic: at worst, four bottles a year is $37.20 before shipping.

That is still the cheapest year of retinol in our shortlist by a wide margin. But it is a cost of the format, not a defect, and it helps to know before you buy two bottles to clear the free-shipping threshold.

Pricing and shipping

On October 21, 2026, theordinary.com listed Retinol 0.5% in Squalane at $9.30 for 30 ml, in stock. That is about $0.31 per ml, or roughly $9.20 per fluid ounce, by our arithmetic.

The site showed a $4.99 shipping charge on orders under $25 and free shipping above it. A single bottle therefore costs $14.29 delivered. Pairing it with a moisturizer or the brand's Niacinamide 10% + Zinc 1% is the obvious way past the threshold.

For comparison, the CeraVe serum in our shortlist was listed at $21.99 for 1 fl oz on CeraVe's own page, and the Paula's Choice 1% at $48.75 on sale from $65.00 for 1 fl oz.

Returns: a year, with one condition

Support scores 4.4, the highest of the three, almost entirely because of the returns policy.

The Ordinary's US policy accepts returns within 365 days of purchase, provided the product is at least 50% full. Refunds go to the original payment method. You pay the return postage, shipping fees are not refunded, and items marked Final Sale are excluded.

The half-full rule is the condition that matters for a retinol. If your skin reacts in the first week or two, you will usually still be above half a bottle. Return it, rather than pushing through.

Bottles bought at Sephora, Ulta or other retail partners follow those retailers' policies, not The Ordinary's.

Pregnancy, sensitive skin and darker skin tones

Three groups should read the warnings closely. Nothing here is medical advice.

The brand says to avoid skincare products containing retinoids when pregnant or breastfeeding. The AAD states that retinoids should not be used during pregnancy.

The AAD also says people with skin allergies or dryness are probably not good candidates for retinoid products, and that people with a lot of redness or inflammation should ask a dermatologist about therapies aimed at rosacea instead.

For darker skin, the AAD quotes a dermatologist warning that irritation can trigger dark marks, known as hyperpigmentation. Starting slowly matters more, not less. If in doubt, a board-certified dermatologist can advise.

Sunscreen is part of the product

Both the brand and the AAD say the same thing: retinoids can make skin more sensitive to the sun, so daily protection is not optional.

The AAD advises using retinoids only at night and protecting skin by day with shade, clothing and sunscreen. Our best face sunscreen for everyday wear guide covers three options, including EltaMD UV Clear and Supergoop Unseen.

If you do not already wear a daily sunscreen, start that habit before you start a retinol.

Alternatives

Two other retinols are in our beginner shortlist and will be published on this site in the coming days.

The CeraVe Resurfacing Retinol Serum is a water-based serum at $21.99 for 1 fl oz with encapsulated retinol, ceramides, niacinamide and licorice root extract, but CeraVe does not state its retinol percentage.

Choose it if you want a lighter texture and barrier ingredients in one step.

The Paula's Choice CLINICAL 1% Retinol Treatment is a higher-strength lotion with peptides and vitamin C, at $48.75 on sale from $65.00. Choose it as a later step, not a first one.

Bottom line

Retinol 0.5% in Squalane is the best-value retinol we graded: a disclosed dose, a short water-free formula, $9.30 a bottle and a year to return it if it does not suit you.

It asks three things in return: start slowly, keep it in the fridge, and wear sunscreen every day. If you can wait, the brand's own advice is to begin with the 0.2%.

Best for

Budget-minded readers with normal to dry skin who want to know exactly how much retinol they are putting on, and who will keep an opened bottle in the fridge.
