To help us unpick exactly what goes into a best-selling product, we conscripted the help of Kiehl's, who has been dishing out potions and lotions since 1851 (how's that for longevity?). What started as a tiny, family-run apothecary on a horn-blasted intersection in New York has grown to become one of the world's most industrious skincare brands and a must-not-miss fixture of our morning and evening routines.

While others have come and gone, each of these five products have stood the test of time. They aren't just good, they're proven performers - swoon-worthy athletes of the skincare world, if you will.

Facial Fuel Energising Moisture Treatment

We'll take our moisturisers as we like our coffee: strong and highly-caffeinated. This caffeine-charged facial treatment is a worldwide bestseller for a reason. As you might expect, the addition of caffeine helps to reduce skin's dullness, while chestnut extract works to improve the skin's barrier function.
