Questions

Common questions

Is the The Ordinary Hyaluronic Acid 2% + B5 or the Vichy Minéral 89 Hyaluronic Acid Booster better?
Neither is universally better — they share 77% active-ingredient overlap, so for the actives that drive results they're close. The The Ordinary Hyaluronic Acid 2% + B5 is the more budget-friendly option, while the other may differ on texture, finish and supporting ingredients. Pick based on your skin's priorities rather than a single 'winner'.
What's the difference between the The Ordinary Hyaluronic Acid 2% + B5 and the Vichy Minéral 89 Hyaluronic Acid Booster?
Both are serums that share Hyaluronic Acid. Where they differ: they sit in different price tiers (Budget vs Mid-range); the Vichy targets Dullness.
Are the The Ordinary Hyaluronic Acid 2% + B5 and Vichy Minéral 89 Hyaluronic Acid Booster dupes for each other?
They share 77% active-ingredient overlap based on published INCI lists, so one can stand in for the other on the actives that matter — chiefly Hyaluronic Acid. A dupe matches the hero actives, not the full sensory experience, so expect differences in texture, fragrance and exact concentrations.
Can I use the The Ordinary Hyaluronic Acid 2% + B5 and Vichy Minéral 89 Hyaluronic Acid Booster together?
They both fill the serum slot in a routine, so you'd normally pick one rather than layer both. If you want to use both, treat one as your daytime option and the other for evening, and patch-test when introducing anything new.
