What is actually different?

A serum and a moisturising cream are different purchases, even when the product names seem determined to start an argument.12

Which should you choose?

Choose The Ordinary if you already have a moisturiser and want a separate serum targeting dryness and dehydration. Choose the Vichy cream if you want the cream step itself and are comfortable using fragrance. Both brands describe these products as suitable for all skin types. For eczema or dry, easily irritated skin, prioritise a fragrance free moisturiser rather than choosing the fragranced Vichy cream. A serum alone is not the same as a routine that also seals in moisture.123

Check which version you are buying

Minéral 89 is a product family, not a sufficiently precise shopping list. Vichy's booster serum and fragranced cream are separate products. The Ordinary also has a newer Hyaluronic Acid 2% + B5 with Ceramides, described as lighter than the original, with an additional form of hyaluronic acid. Match the bottle to the version you want before using the texture comparison above.12

How do you use them?

  1. 1Cleanse gently. For dry skin, leave the skin slightly damp before applying moisturiser.
  2. 2If using The Ordinary original serum, apply a few drops to the face morning and evening. Use only on unbroken skin.
  3. 3Follow the serum with moisturiser. If using the Vichy cream, gently massage it into clean face, neck and chest until absorbed. Vichy directs cream application after its own booster.
  4. 4In the morning, apply sunscreen after the cream. Choose broad spectrum, water resistant SPF 30 or higher.

What results should you expect?

Hyaluronic acid is a humectant, meaning it attracts and binds water. The practical goal is better hydration and smoother looking skin. Vichy claims hydration lasting up to 72 hours after the first cream application; The Ordinary describes hydration and smoother looking skin without giving a result timeline here. Neither comparison establishes a winner for your skin. For persistent dryness, a cream or ointment matters because retaining moisture requires more than attracting water.12356

Who should be careful?

Patch test The Ordinary before facial use. If irritation occurs, rinse it off, stop using it and consult a physician. Rinse eyes thoroughly if the Vichy cream gets into them. Hyaluronic acid itself is considered safe during pregnancy and nursing; combination products need consideration of their other ingredients. If you use prescription skin medication, ask your prescriber about the complete formula. See a dermatologist if dryness persists despite moisturising, or products cause burning, stinging or irritation.1257
