Quick Verdict

The current The Ordinary Hyaluronic Acid 2% + B5 is a strong-value hydration serum with five forms of hyaluronic acid, panthenol and a phospholipid-and-sphingolipid blend marketed as ceramides. Its second-generation texture is lighter than the original, and professional sources generally find it easy to layer. It still requires sensible application: too much product can pill, and a hyaluronic-acid serum does not replace moisturizer. Manufacturer testing supports hydration and temporary plumping, but no independent quantitative study of the current formula was found. At around $10 for 30 ml through some US channels, value remains its clearest competitive advantage.

Key Facts and Review Scope

This review covers the current US The Ordinary Hyaluronic Acid 2% + B5 (with Ceramides).

It is the second-generation version of the brand’s long-running hyaluronic-acid serum. The Ordinary continues to distinguish it from an Original Formulation, which has a richer texture and four molecular weights of hyaluronic acid rather than the current version’s five-form system.

The current formula includes:

Sodium hyaluronate
Hydrolyzed hyaluronic acid
Sodium hyaluronate crosspolymer
Additional low-, medium- and high-molecular-weight HA forms
Panthenol
Glycerin
Phospholipids
Sphingolipids
Red-algae extract
Supporting solvents, stabilizers and preservatives

The brand publishes a pH range of 6.0–7.5 and identifies the serum as alcohol-free, oil-free and silicone-free. It recommends applying a few drops in the morning and evening.

At the time of verification:

The Ordinary US: $9.90 for 30 ml and $17.50 for 60 ml
Ulta: $9.90 for 30 ml
Sephora: $12 for 30 ml

Prices and promotions can change.

Evidence-Based Analysis

Performance

The serum’s main function is supplemental hydration.

Hyaluronic acid binds water at the skin’s surface, helping dehydrated areas feel softer and look temporarily plumper. The current product combines several forms of HA with different molecular characteristics rather than relying on a single sodium-hyaluronate ingredient.

The Ordinary says the five-form system hydrates multiple levels of the skin’s surface. That wording is more defensible than suggesting that a topical cosmetic serum travels deeply into the dermis.

Allure describes the reformulated serum as lightweight, fast-absorbing and easier to wear beneath moisturizer or makeup than the thicker original. Its editor reported an immediate plumping effect, while the publication also recognized the product in its 2026 Readers’ Choice coverage.

People’s editor similarly described routine improvements in hydration and surface smoothness. These reports support the product’s basic purpose, but they remain editorial experience rather than controlled clinical proof.

Understanding the Manufacturer Test

The Ordinary reports clinical testing in 32 people who used the serum twice daily.

According to the brand:

Hydration and barrier support occurred immediately.
Skin felt smoother and softer after one week.
Skin appeared firmer and plumper after two weeks.
Lines, elasticity and nasolabial-fold appearance improved after four weeks.

The test summary is more informative than an unsupported marketing statement because it identifies the sample size and frequency. However, it does not disclose the control group, demographics, climate, instruments, numerical effect size or statistical significance.

The results should therefore be understood as manufacturer-generated evidence with incomplete public methodology. They do not prove that every user will see smoother wrinkles or visibly plumper folds after four weeks.

Five Forms of Hyaluronic Acid

The serum combines low-, medium- and high-molecular-weight hyaluronic acid with hydrolyzed hyaluronic acid and a crosspolymer.

Different molecular structures can alter a formula’s texture, water-binding behavior and surface persistence. A crosspolymer may remain on the surface differently from a smaller hydrolyzed form.

The presence of five forms does not automatically establish that the product is five times more hydrating than a serum containing one form. Performance depends on the complete formula, concentration, application amount, humidity and the moisturizer applied afterward.

The public ingredient list also does not disclose the amount of each form. The “2%” in the name refers to the product’s hyaluronic-acid complex as formulated by the brand and should not be interpreted as 2% pure high-molecular-weight hyaluronic acid.

Ceramides and Barrier Support

The updated formula’s most visible change is the addition of a lipid blend marketed as ceramides.

The ingredient list names phospholipids and sphingolipids rather than individually naming Ceramide NP, Ceramide AP or Ceramide EOP. These lipids are relevant to barrier-support formulation, but the public documentation does not reveal their exact concentration or composition.

Panthenol provides additional hydration and conditioning support. Glycerin also contributes humectant activity.

The combination makes the new formula broader than a basic single-humectant serum. However, it does not turn the product into a complete barrier cream. A leave-on moisturizer generally supplies a more substantial mixture of humectants, emollients and occlusive ingredients.

Texture and Layering

The updated texture is intended to resolve one of the original serum’s most common criticisms: stickiness.

Allure found the second-generation formula lightweight and non-sticky. Many Ulta reviewers also say it is easier to absorb and more pleasant than the previous version.

The improvement is not universal. Recent Ulta feedback still includes reports of:

Sticky residue
Flaking after drying
Pilling beneath other products
A peel-like film
Tightness after application

These complaints recur often enough to warrant disclosure, but they do not establish how frequently the problem occurs.

Pilling is more likely when too much serum is used or several polymer-rich products are layered together. A practical application method is:

Apply one to three drops rather than covering the face with a thick layer.
Spread the serum over slightly damp—not dripping-wet—skin.
Allow it to settle briefly.
Apply moisturizer without prolonged rubbing.
Reduce the number of layered serums if rolling persists.

These steps may improve compatibility but cannot guarantee that the formula will work beneath every sunscreen or makeup product.

Why Moisturizer Still Matters

Hyaluronic acid is a humectant, not a complete moisturizer.

It helps bind water, but the routine still needs ingredients that reduce evaporation and improve comfort. The serum already contains a small supporting lipid system, yet it lacks the richer emollient and occlusive structure of most creams.

Users in dry air may find that a standalone HA serum eventually feels tight. This does not necessarily mean that hyaluronic acid is “pulling all moisture out of the skin.” It more often indicates that the routine lacks enough water, emollience or occlusion for the environment and skin type.

For most users, the serum makes the most sense beneath a moisturizer rather than in place of one.

Fine Lines and Plumping

A well-hydrated skin surface can make fine dehydration lines look softer. Temporary plumping is therefore a plausible cosmetic benefit.

That should not be confused with rebuilding collagen, permanently filling wrinkles or changing facial anatomy. Topical hyaluronic acid is different from injectable hyaluronic-acid filler.

The manufacturer’s four-week claims include smoother-looking lines and plumper-looking nasolabial folds, but no independent wrinkle-imaging or profilometry study of this exact formula was found.

The product should be evaluated primarily as a hydration serum, not as a substitute for evidence-based wrinkle treatments or procedures.

Quality and Materials

The ingredient list is relatively focused and avoids fragrance, oils and silicones. That can make it easier to fit into routines already containing treatment products.

The inclusion of several humectants and lipid-support ingredients gives the serum a more complete structure than a basic water-and-sodium-hyaluronate solution. The slight yellow tint noted by Sephora comes from the new ceramide blend and is identified as normal for the formula.

Ingredient transparency is strong, but several technical details remain proprietary:

Molecular-weight ranges
Concentration of each HA form
Concentration of panthenol
Composition of the lipid blend
Raw-material specifications
Batch stability
Packaging oxygen and light protection

The dropper bottle is familiar and easy to dose, although repeated opening exposes the formula to air and handling. The preservative system is publicly disclosed, but no independent stability or contamination test was reviewed.

Safety and Compliance

This is a conventional cosmetic hydrating serum, not a drug treatment.

It does not contain exfoliating acids, retinoids or benzoyl peroxide, so it is less inherently aggressive than many treatment serums. It is also fragrance-free according to the brand’s formulation disclosures.

Individual reactions remain possible. Ulta reviews include recurring reports of:

Stinging
Redness
Rash
Tightness
Dryness
Breakouts

These accounts cannot establish causation or frequency. Some may involve application technique, another product, a compromised barrier or use of an older formula. They are nevertheless sufficient to reject any assumption of universal compatibility.

The Ordinary advises patch testing, use on unbroken skin and discontinuation if irritation occurs. Persistent swelling, rash or painful irritation requires more caution than simply reducing the number of drops.

Transparency and Evidence

The Ordinary performs well in several transparency areas.

The company clearly provides:

Complete ingredient list
pH range
Current-generation status
Differences from the original formula
Package sizes
Directions
Patch-test guidance
Manufacturer-test sample size and usage frequency
A warning that ingredients may vary by time and region

The main weakness is the limited depth of public claim substantiation. The 32-person test is not accompanied by enough information to assess the strength of the findings independently.

The use of “with Ceramides” also deserves qualification because the ingredient list identifies a phospholipid-and-sphingolipid blend rather than specifying named ceramides and their concentrations.

Value for Money

Value is the product’s strongest category.

The official and Ulta price of $9.90 for 30 ml places the serum well below many prestige hyaluronic-acid products. The 60 ml bottle at $17.50 offers a slightly lower cost per milliliter.

A few drops are sufficient for the face, so one bottle may last a reasonable period when it is not overapplied.

The serum is not automatically better value than using a well-formulated moisturizer alone. Consumers whose moisturizer already contains glycerin, hyaluronic acid and barrier lipids may see limited additional benefit.

Value is highest for users who notice a meaningful improvement in dehydration and can layer the product without pilling.

Independent Evidence and Recurring Community Feedback

Independent professional evidence generally supports the serum’s basic hydration function and improved texture relative to the original. Allure, People and Who What Wear recognize it as an affordable hydrating option, although none provides an independent laboratory study of the exact finished formula.

Best For and Not Ideal For

Best For

Dehydrated skin needing supplemental hydration
Budget-focused skincare routines
Users who found the original formula too thick
People seeking a simple serum beneath moisturizer

Not Ideal For

Routines already prone to product pilling
Anyone expecting permanent wrinkle correction
Users seeking a rich standalone moisturizer
People who strongly preferred the original formula

Final Verdict

The current The Ordinary Hyaluronic Acid 2% + B5 is one of the better-value dedicated hydration serums in the US market. Its five-form HA system, panthenol and lipid blend offer a sensible formula for temporary plumping and improved surface comfort, while the second-generation texture is generally lighter than the original.

The product is not as universally non-tacky as the brand suggests. Pilling, flaking and tightness recur in retailer feedback, particularly when too much serum is layered beneath several products. Its barrier and four-week wrinkle claims also rely mainly on a small manufacturer test with limited public methodology.

Used sparingly beneath a suitable moisturizer, it is an affordable and credible hydration step. Users whose moisturizer already supplies adequate humectants and barrier lipids may not need it, and anyone expecting deep wrinkle correction or a complete moisturizer replacement should choose based on more realistic goals.
