Serum can penetrate really deep into your skin more so than a moisturiser giving it a real boost and leaving it brighter, firmer and more radiant, says expert Nicole Doe. ‘ apply morning and night after cleansing and toning and before moisturing. apply lightly, using sweeping movements in an upward direction all over the face and neck.’ If you’re noticing the first signs of ageing, try L’Occitain Fabulous Serum 30ml. Those with mature skin should try Champneys Age Excellence Ultimate 24 Garat Gold Serum 30ml
