La Roche-Posay Hyalu B5 serum

"A simple hydrating step: hyaluronic acid plus vitamin B5, a few drops before your moisturizer."

Why we picked it

We chose it as one simple hydrating step you can add without rebuilding your routine: a few drops before moisturizer.

  • Hyaluronic acid plus vitamin B5
  • Dropper bottle, a few drops at a time
  • The brand says it suits sensitive skin
Size
1 oz (30 ml) dropper bottle
Formula
hyaluronic acid, glycerin, vitamin B5 and madecassoside; oil-free, per the brand
Skin
all skin types, including sensitive, per the brand

Skip it if you want to treat a skin condition; that is a question for a dermatologist. Patch-test first if your skin reacts easily.

Before you buy

  • Where it goes: a few drops on clean, slightly damp skin, before moisturizer.
  • Sensitive skin: La Roche-Posay describes it as suitable for sensitive skin; patch-test on the jaw for a few days first if you react easily.
  • One product at a time: add it alone and give it two weeks before judging it or adding the next.

Fits: One simple hydrating step for dry-air months, without rebuilding a routine.

Not for: Treating a skin condition; that is a question for a dermatologist, not a serum.
