Vitamin B Serum 10%

Niacinamide at 10% with panthenol and hyaluronic acid. A water-light serum that sits under most other things in a routine.

Niacinamide — Vitamin B3 — at 10%, which is the upper end of what is commonly formulated. Panthenol (Vitamin B5) and two forms of hyaluronic acid, one of them a crosspolymer, sit with it in a water base. Nothing here exfoliates, so it can be used morning and night and alongside most other actives.

Ten per cent is enough that some skin flushes on first use. If that happens, use it every second night for a fortnight and build up. Flushing settles for most people. If it does not settle, stop.

Made for most skin states, including skin currently taking a break from acids or Vitamin A.

Actives: Niacinamide (Vitamin B3) 10%, Hyaluronic Acid, Panthenol (Vitamin B5)

Suits: Most skin states, including skin currently off acids or Vitamin A.

Not for: Skin that flushes readily should build up slowly. Contains fragrance.
