Hyaluronic Acid 2% + B5

Looks good 4.6 / 5

A solid, straightforward hydration serum with good barrier-supporting ingredients and a verified ingredient list for the exact The Ordinary ceramides variant. It is best viewed as a basic support step rather than a stand-alone treatment, with the main tradeoff being that it needs a moisturizer to perform well.

Skin

How it’s judged

Scored for skin — based on what its ingredients contribute.

What it may help with

Hydration i4.0 / 4

Whether the ingredient helps increase the skin’s water content — humectants that attract water, ingredients that reduce water loss, or ones that make skin feel less dry.

From Sodium Hyaluronate Crosspolymer, Sodium Hyaluronate, Hydrolyzed Hyaluronic Acid, Panthenol

Barrier support i3.5 / 4

Whether it supports the skin barrier — restoring lipids, reducing water loss, aiding barrier repair, or strengthening the skin’s protective function.

From Sphingolipids, Sodium Hyaluronate Crosspolymer, Phospholipids, Sodium Hyaluronate

Soothing i3.0 / 4

Whether it can calm the skin — linked to less redness, irritation, discomfort, or visible reactivity.

From Panthenol, Sodium Hyaluronate, Hydrolyzed Hyaluronic Acid, Sodium Hyaluronate Crosspolymer

Texture i3.0 / 4

Whether it can improve smoothness and surface texture — roughness, flaking, clogged pores, or unevenness. Exfoliating acids, retinoids, and smoothing moisturizers may score here.

From Citric Acid, Sodium Hyaluronate Crosspolymer, Panthenol, Sodium Hyaluronate

Anti aging i2.8 / 4

Whether it can help visible signs of aging — fine lines, wrinkles, loss of firmness, or photoaging.

From Sodium Hyaluronate, Tocopherol, Hydrolyzed Hyaluronic Acid, Sodium Hyaluronate Crosspolymer

Things to watch

Photosensitivity i2.5 / 4

Whether it can make skin more sensitive to sunlight, raising the risk of sunburn or UV-related irritation. Relevant for some exfoliating acids, retinoids, and certain plant-derived ingredients.

From Citric Acid

Irritation i2.0 / 4

Risk of short-term irritation — stinging, burning, dryness, redness, or discomfort. Common for strong actives, acids, retinoids, fragrances, and harsh surfactants.

From Citric Acid, Ethylhexylglycerin, Phenoxyethanol, Pentylene Glycol

Sensitization i1.5 / 4

Risk of allergic contact dermatitis or immune-based reactions. Fragrance allergens, preservatives, botanicals, and some dyes may score here.

From Chlorphenesin, Citric Acid, Ethylhexylglycerin, Phenoxyethanol

Eye irritation i1.5 / 4

Whether it may sting or irritate around the eyes. Relevant for sunscreens, fragrances, acids, surfactants, and volatile ingredients.

From Phenoxyethanol, Citric Acid, Ethylhexylglycerin

Barrier disruption i1.0 / 4

Whether it can weaken or damage the skin barrier — harsh surfactants, strong exfoliants, high alcohol content, or overuse-prone actives.

From Citric Acid

About this product

This is a water-based hydrating serum from The Ordinary's Hyaluronic Acid 2% + B5 line, specifically the ceramides version. The official product page confirms the exact variant, full INCI list, and position it as a lightweight hydration and barrier-support serum with five forms of hyaluronic acid, ceramides, and panthenol. The formula looks straightforward and functional, but it is not a treatment for acne, pigment, or wrinkles beyond basic hydration support.

Good signs
  • Multiple forms of hyaluronic acid support surface and layered hydration.
  • Ceramides and panthenol add barrier-supporting moisture help.
  • Fragrance-free and oil-free, which suits many simple routines.
  • Lightweight serum format is generally easy to layer under creams or sunscreen.
Watch-outs
  • Hydration is the main function; claims about smoothing lines are modest and depend on regular use plus proper moisturizing.
  • Can feel tacky or short-lived if used without an occlusive moisturizer on top.
  • Preservatives and acids in the base formula may still irritate very reactive skin, even though the product is not heavily active.
  • No barcode was found on the sourced pages, so retail code verification is incomplete.
Best for
  • dry or dehydrated skin needing a basic hydration layer
  • simple routines that avoid fragrance and heavy oils
  • users looking for lightweight barrier support before moisturizer
  • all skin types
  • dry
  • dehydrated
  • sensitive
How to use it
  • Apply a few drops to damp or slightly moist skin after cleansing.
  • Follow with a moisturizer to reduce water loss and improve lasting hydration.
  • Patch testing is sensible for sensitive or compromised skin.
  • Use morning and evening if tolerated.
