Side-by-side comparison

Haruharu Wonder Black Rice Hyaluronic Serum vs The Ordinary Hyaluronic Acid 2% + B5

Both serums contain Hyaluronic Acid, but only Haruharu Wonder Black Rice Hyaluronic Serum adds a targeted active: Niacinamide. That's the main thing to weigh.

1Shared hero active
Haruharu Wonder
SerumBudgetMorning or evening
DullnessDrynessDamaged Barrier

Fermented black rice extract with niacinamide and hyaluronic acid. Antioxidant-leaning hydrator rather than a targeted active — a good 'daily vegetable' layer under stronger serums.

The Ordinary
SerumBudgetMorning or evening
DrynessDamaged Barrier

A water-based humectant serum combining three molecular weights of hyaluronic acid with a crosspolymer and panthenol. Surface and deeper-layer hydration in one step. Apply to damp skin and seal with moisturiser — on bare dry skin, HA can pull water outward and make things worse.
