Smoother skin in just one week, brighter skin in two weeks – that’s what 90 per cent of Asian women observed while using Kiehl’s Iris Extract Activating Treatment Essence, $72.

Iris Florentina Root extract, the star ingredient here, is grown in the Mediterranean region, and is chock full of flavonoids, which protect as they nourish. The extract also helps to reduce fine lines, impede oxidation and lock in moisture for up to 24 hours after application.  

The silky texture of the essence ensures that it goes on skin smoothly and penetrates easily to improve radiance. Use after your cleanser and before your moisturiser.  

Available from May at Kiehl’s counters.
