Multivitamins aren't only for swallowing – when applied to your skin, they help it recover and protect against signs of ageing. Dermalogica's Multivitamin Power Serum harnesses these abilities and soothes away ruddiness, dryness and fine lines.

Vitamins A and C reach past the surface layer of your skin to repair deeper damage and vitamin E heals and reduces scarring. Protein peptides help to counteract biochemical triggers, boosting collagen levels so that slack jawlines are tightened and smoothed.

There really is a fountain of youth, and Dermalogica has discovered it: we're quite sure there's a Nobel Prize in it for them somewhere. Knock back the years and rediscover a younger you.
