Serums are often the priciest element to a skincare routine because they contain concentrated key ingredients.

They have smaller molecules too, so skin absorbs them faster and deeper than a moisturiser - you only really need a tiny pea-sized amount, so despite the expense, they will last you ages. Think of serums as the cure; they undo previous damage or combat specific issues such as ageing, acne, sun damage, or dehydration.

We've worked our way from Revitaline Skin Complex to The Organic Pharmacy Anti-Oxidant to find the best performing serums out there. The Revitaline Skin Complex smells divine, works a treat and is chemical-free. Details The serum costs $56 for 30ml available online and at leading retailers.
