The Ordinary Hyaluronic Acid 2% + B5

A water-based humectant serum, sold now as the "with Ceramides" version in a 30 ml dropper bottle, for the optional second layer; this entry reads all 23 ingredients and what the name does and does not tell you.

The short version

  • A water-based serum with 23 listed ingredients: three hyaluronic acid ingredient names, panthenol (pro-vitamin B5) and lipids; 30 ml (1 fl oz) dropper bottle.
  • $9.90 on Amazon on Sep 30, 2026, about $0.33 per ml, sold by Amazon.com; the listing marks it non-returnable.
  • The brand says it contains ceramides, but no ingredient named "Ceramide" appears on the list; the closest entries are Sphingolipids and Phospholipids.
Layer 01Cleanse

Not a cleanser; it goes on clean skin.

Layer 02Treat

The optional serum step, before creams or oils.

Layer 03Moisturize

Not a moisturizer; a cream or lotion goes over it.

Layer 04Protect

No SPF; sunscreen is the last morning step.

Morning and evening per the brand's product page; the Amazon listing's directions say once daily or as needed.

The full label

We printed the list from The Ordinary's U.S. product page for Hyaluronic Acid 2% + B5 (with Ceramides), read on Sep 30, 2026. The Amazon listing's ingredient text is identical. The brand notes that its formulas are updated from time to time and the box may differ from the page.

Key ingredientWhat it isWhat to know
Sodium HyaluronateSalt form of hyaluronic acid; humectantSecond on the list. One INCI name can cover several molecular weights, and the brand says the serum uses low, medium and high weights.
Hydrolyzed Hyaluronic AcidHyaluronic acid broken into smaller fragmentsSmaller molecules; a lab study found lower-weight HA crossed the outermost skin layer while high-weight HA did not [2].
Sodium Hyaluronate CrosspolymerCross-linked hyaluronic acidA cross-linked form; the brand counts it among its five "types" of hyaluronic acid.
SphingolipidsLipid class that includes ceramidesCeramides are a group of sphingolipids [4]. The list does not name a specific ceramide.
PanthenolPro-vitamin B5; humectantThe "B5" in the name. A review summarizes studies on skin moisture and barrier measures for its active form, dexpanthenol [3].

What the evidence and the label claims say

What "2%" means. The product page we read does not say what the 2% is measured against: whether it counts all of the hyaluronic acid forms together, or refers to a pre-made hyaluronic acid solution. Treat it as part of the product's name rather than a verified concentration. The list order tells you something: sodium hyaluronate sits second, right after water, and the other two hyaluronic acid names follow within the first six entries.

What changed. The brand calls this a second-generation version of its original serum. It says the new version has five types of hyaluronic acid (low, medium and high molecular weight, a crosspolymer and a hydrolyzed form), adds ceramides and keeps panthenol, with a lighter, non-tacky texture [1]. The brand still sells an "Original Formulation", which it says has four molecular weights and a richer feel, so check which one a listing shows. The page lists a pH of 6.0 to 7.5 and calls the formula alcohol-free, oil-free, silicone-free and vegan. On ceramides, we can only report what the list shows: Sphingolipids and Phospholipids appear, but no ingredient named Ceramide NP, AP or similar. Ceramides are one family within the sphingolipids [4], so the brand's wording is consistent with the list, but the label does not say which ones or how much.

What research shows. Hyaluronic acid is a humectant: it holds water. Where it ends up depends on molecule size. In a study using human skin samples and Raman imaging, lower-weight hyaluronic acid (20 to 300 kDa) passed through the stratum corneum, while high-weight hyaluronic acid (1,000 to 1,400 kDa) did not [2]. That is a lab measurement of where the molecule went, not a test of how skin looks or feels. For panthenol, a review of topical dexpanthenol describes studies of skin moisture and barrier function; its authors are from a university dermatology department and a consumer-health company that sells dexpanthenol products [3]. Neither source tested this serum.

Before you buy

The Amazon listing title carries appearance promises we don't repeat; judge the product by its ingredient list. The listing is also marked non-returnable. If you want to compare with the older, richer texture, look for "Original Formulation" in the title.

Where it goes in a routine

This is the order the brand describes, not a promise about results.

  1. Patch test first

    The brand advises testing on the upper forearm first and not using the product if redness, burning, itching or irritation appears.

  2. Cleanse

    Start with clean skin; see 01 Cleanse.

  3. Apply a few drops

    Spread a few drops over the face. The brand says it goes on after cleansing and before heavier creams or oils; the brand's FAQ says it can be used alongside other active ingredients.

  4. Seal with moisturizer, then protect

    Follow with a moisturizer. In the morning, finish with a broad-spectrum sunscreen.

Price and where it is sold

On Sep 30, 2026 the Amazon listing for the 30 ml bottle (ASIN B0CXKG6YWH, the "with Ceramides" version) showed $9.90, about $0.33 per ml ($9.90 per fluid ounce), in stock, shipped and sold by Amazon.com. The listing states "This item is non-returnable." The brand also makes a 60 ml size. See the listing on Amazon (as an Amazon Associate we earn from qualifying purchases).

Who should look elsewhere

  • Anyone who has reacted to one of the 23 listed ingredients.
  • Anyone who wants a single step that both hydrates and seals: a serum still needs a moisturizer over it, such as the CeraVe Moisturizing Cream.
  • Anyone who wants specific, named ceramides on the label; the list shows only the broader "Sphingolipids".
