IRÉN Skin is a Japanese skincare brand that integrates age-old Japanese rituals with cutting edge technology. It was founded by Kristin and stands with these 3 convictions: transparency, customizable and visible results. All séruns have a patented technology – Ziplock Encapsulation™ – allows active ingredients to be better absorbed into the skin deeper layers. This technology allows each active ingredient to be encapsulated into a nano sized molecule increasing skin penetration and a time release effect. You can mix up to 3 serums with no contradiction and use it in one single step, made possible with this patented technology, Ziplock Encapsulation™. Irén Skin is vegan, cruelty-free and committed to limiting their impact by reducing the use of single-use plastic, and replacing them with PCR (recycled plastic) and glass, and also using FSC-certified paper for all of the exterior packaging.
