What you pay

The Body Hydrator HA Body Serum is $26.99 CAD for 386 mL (13 fl oz). The Ordinary HA 2% + B5 (with Ceramides) is $12.00 CAD for 30 mL. Per millilitre, that's roughly $0.07 CAD vs $0.40 CAD, the Body Hydrator is dramatically cheaper per mL, even at a higher sticker price.

What the bottle actually covers

The Body Hydrator's 386 mL pump bottle is built for the whole body, applied generously after a shower. The Ordinary's 30 mL dropper is a face serum, a few drops per application, twice daily. Using The Ordinary on your body would burn through the bottle in days and cost far more per session.

Ingredients and formulation depth

The Body Hydrator delivers sodium hyaluronate, red algae, magnesium chloride, and a phyto-collagen complex (a plant-based amino acid blend for elasticity support). The Ordinary HA 2% + B5 (with Ceramides) includes five molecular weights of hyaluronic acid, pro-vitamin B5 (panthenol), and ceramides (phospholipids and sphingolipids) for multi-depth skin barrier support. For the face, that five-form HA stack and ceramide barrier reinforcement is a meaningfully more targeted formulation. The Body Hydrator has no ceramides and its HA depth is not specified beyond sodium hyaluronate.

Texture and application experience

The Body Hydrator is a sheer, fast-absorbing gel applied to damp skin, fragrance-free, no residue, works under a moisturizer or alone. The Ordinary serum has a lightweight, non-tacky finish per the reformulated ceramide version, though Canadian reviewers on well.ca note it can dry skin out if applied without adequate moisture present. Both are fragrance-free and sensitive-skin safe.

Fit: face vs body

The Ordinary is formulated and sized for facial use, with a pH of 6.5–7.5 and ingredients clinically known to address fine lines and barrier repair. The Body Hydrator is sized and priced specifically for full-body coverage, which is its primary advantage. Neither product does the other's job well at its given size.

Common questions

Which is cheaper, Body Hydrator Hyaluronic Acid Body Serum or The Ordinary Hyaluronic Acid 2% + B5 (with Ceramides)?

The Ordinary HA 2% + B5 is cheaper by sticker price at $12.00 CAD vs $26.99 CAD on amazon.ca, but the Body Hydrator gives you 386 mL vs 30 mL, making it roughly 5x cheaper per millilitre.

Is Body Hydrator Hyaluronic Acid Body Serum better than The Ordinary Hyaluronic Acid 2% + B5 (with Ceramides)?

For full-body hydration, yes — the Body Hydrator at $26.99 CAD for 386 mL is built and sized for that job; The Ordinary's 30 mL face serum offers a more advanced formulation with five HA forms and ceramides, but it's the wrong tool for covering a whole body.

What's the biggest difference between them?

Intended use area: the Body Hydrator is a 386 mL body serum at $0.07 CAD/mL, while The Ordinary is a 30 mL face serum at $0.40 CAD/mL — same hero ingredient, completely different scale and purpose.
