Algae-infused Skincare

While a common moisturizer or serum will nourish the outer layers of the skin, cosmeceuticals work on a deeper layer using potent vitamins, minerals and other beneficial active ingredients to tackle dryness and dehydration, dullness, sun damage, acne, scarring and signs of ageing.


Algae-infused Skincare is serious skincare. It incorporates biologically active ingredients that can alter the function of your skin in the long term… instead of just making it feel nice and fluffy for two seconds.

​You may find an inexpensive serum that contains say, retinol, but you’re likely paying for the quality and the source, the potency and the bioavailability. Think of it as the difference between an acrylic knit jumper and a cashmere one. It may have the same purpose, but if it’s a low-grade ingredient, or if the potency is minuscule, it won’t be doing much for you in the long run.

Kate Benji is serious about skincare and our product will change your skin from within and restore your cell function.
