What is it?

The Ordinary Hyaluronic Acid 2% + B5 is a hydrating serum designed to tackle dehydration and improve overall skin smoothness and bounce. It combines low, medium and high molecular weight hyaluronic acid plus a crosslinked HA polymer (4 forms total) at a 2% concentration for multi-layer hydration in an oil-free base.

This system is supported with pro-vitamin B5 (Panthenol), which helps enhance surface hydration and supports a healthier moisture barrier. With consistent use, the serum helps the skin feel plumper, softer and more elastic, and reduces the look of fine, dehydration lines.

The texture is a clear, slightly viscous water-based serum that absorbs quickly and layers easily under moisturiser and SPF.


Who is it for?

✔ All skin types – oily, combination, dry, balanced and sensitive
✔ Dehydrated skin (tight, dull, fine lines that disappear when you moisturise)
✔ Anyone using actives (retinoids, acids, acne treatments) who needs extra hydration and barrier support
✔ People who want a simple, affordable hydrating step that fits into any routine

If your skin constantly feels like it needs “more water” rather than more heavy cream, this is the kind of serum that helps.


Why you’ll love it

  • Multi-depth hydration with 4 forms of HA
    A blend of low, medium and high molecular weight hyaluronic acid plus a crosslinked HA polymer targets hydration at different levels of the skin’s surface, helping to keep it plump and bouncy for longer.

  • Pro-vitamin B5 for barrier comfort
    Panthenol (Vitamin B5) is a soothing humectant that helps the skin attract and hold onto water and supports the formation of barrier lipids, so the skin feels softer, calmer and more resilient.

  • Hydrating humectant base
    Ingredients like glycerin, pentylene glycol, propanediol and caprylyl glycol add extra humectant power, so you’re not just relying on hyaluronic acid alone.

  • Barrier-respecting formula
    Alcohol-free, fragrance-free and essential-oil-free, which makes it a good pick for sensitive, reactive or redness-prone skin that still needs hydration.

  • Pairs with almost everything
    Because it focuses on hydration and barrier support, it layers well with most active routines – retinoids, vitamin C, exfoliating acids, acne treatments – provided you don’t over-do it elsewhere.

When to use
AM and/or PM, after cleansing and toner/essence, before heavier serums and moisturiser.

Step-by-step

  1. Prep the skin
    Cleanse and (optionally) apply a hydrating toner or mist.
    Skin should be slightly damp – hyaluronic acid works best when there’s water to grab onto.
  2. Apply the serum
    Use 2–3 drops (or a small pea-sized amount) into clean hands.
    Spread over face and neck, avoiding the immediate eye area.
  3. Work it in
    Gently press and glide the serum over the skin.
    Spend 30–60 seconds lightly massaging and pressing until it feels mostly absorbed.
  4. Seal it in
    Follow with a moisturiser to lock that water in and prevent evaporation (this step is key with any HA serum).
  5. Daytime = SPF
    In the morning, finish with a broad-spectrum SPF 30–50 as your last step.

Tips to get the most out of it

  • Always use on damp (not dripping) skin, then follow with moisturiser – otherwise HA can feel like it’s doing nothing or even making you feel tighter.
  • If your routine is heavy on actives, pair this serum with a gentle cleanser and barrier-friendly moisturiser to keep everything balanced.
  • Dehydration lines take time – give it 4–6 weeks of consistent use for best results.

Patch-test first. Dab a little behind your ear or on your jawline and wait 24 hours before full use, especially if your skin is sensitive or reactive.

Key Ingredients Explained

Sodium Hyaluronate & Sodium Hyaluronate Crosspolymer
Forms of hyaluronic acid that help the skin attract and hold onto water, increasing plumpness and elasticity. The crosspolymer form creates a water-filled “mesh” on the skin for more long-lasting hydration compared with standard HA.

Hydrolysed / Multiple HA weights (system)
The formula uses low, medium and high molecular weight HA plus a crosspolymer to target different levels of the stratum corneum, giving more uniform, multi-depth hydration than a single HA type.

Panthenol (Pro-Vitamin B5)
Soothing humectant that helps boost moisture levels, support barrier lipid production and reduce feelings of tightness or irritation. Great in routines with actives or retinoids.

Glycerin
Classic “superstar” humectant that draws water into the outer layers of the skin, helping it stay soft, bouncy and less prone to dehydration lines.

Ahnfeltia Concinna Extract (Red Marine Algae)
Red algae extract that helps protect the skin and slightly thicken the texture, and may assist HA in maintaining hydration by supporting the moisture environment on the skin’s surface.

Pentylene Glycol, Propanediol, Caprylyl Glycol, Ethoxydiglycol, Hexylene Glycol
Multi-tasking humectants and emollients that improve slip, boost hydration and help the product feel silky on the skin, while also helping to stabilise the formula.
