No7 Restore & Renew FACE & NECK MULTI ACTION SERUM, from £29.95, Boots

Perfect for: Ages 60+ Designed to: Smooth and firm skin across the face, jawline and neck. As skin ages, it becomes thinner and collagen levels fall, which can lead to a crêpey complexion and sagging skin. This serum contains the same anti-wrinkle, firming and brightening ingredients as No7’s other super serums, but also targets mature skin with a nourishing complex of ceramides, calcium and amino acids.
