Meet Esse Probiotic Serum. This innovative serum actively shapes the skin’s ecosystem with over 1 billion live probiotics per millilitre. Water-free and encapsulated, the probiotics activate on contact with skin moisture (or an Esse moisturiser) to restore balance, strengthen the barrier, and support firmer, fuller, and more resilient skin.
Esse Probiotic Serum nurtures, protects, and enhances the skin’s natural defences while promoting overall health and vitality.
Can be used twice daily. Apply a few drops to damp skin or follow with an Esse moisturiser to activate the probiotics, then massage gently until absorbed.

Prysm io is a cutting edge testing tool that non-invasively measures carotenoid levels in the skin, providing an immediate indication of a person's overall antioxidant levels. How does it work? Prism iO uses thousands of hyperspectral absorption measurements per second to accurately assess skin carotenoid levels. What can be measured, can be improved.
