Pure Marine Active Eye Concentrate Power
The skin under your eyes naturally tends to be the thinnest, so hydration is important for this part of your face to reduce ageing and wrinkles. This eye concentrate features brown algae, which is rich in minerals and vitamins to help nourish and moisturise the skin. Hydrating the skin underneath your eyes daily can help banish dark circles and tired-looking eyes, and what a difference that can make to your overall look. This is a beauty essential.
