The best vitamin C serum in Australia, ranked.
Vitamin C is one of two actives with real anti-ageing evidence. But formula stability makes most vitamin C serums pointless by week three. Three that actually work.

Common questions
What concentration of vitamin C is best?
10-20% L-ascorbic acid, depending on skin tolerance. Below 10% is too weak. Above 20% just irritates without adding benefit.
How do I know if my vitamin C has oxidised?
Oxidised vitamin C turns yellow-brown. Once that happens, it's not active anymore. Store in fridge, use within 6 months.
