The Biologi Bk Vitamin C Face & Eye Serum harnesses the power of Australian Kakadu Plum — one of the most Vitamin C-rich plants on earth — to deliver a stable, plant-derived Vitamin C serum for the face and delicate eye area. Unlike synthetic ascorbic acid, the naturally occurring Vitamin C in Bk is extracted using Biologi's patented C.L.E.C.S.™ II process, keeping phyto-nutrients intact and bioavailable without synthetic stabilisers.
With just four ingredients, Bk targets visible signs of ageing, uneven skin tone, pigmentation, dark circles and redness. Its phyto-actives — plant Vitamin C, Gallic Acid and Ellagic Acid — increase collagen production, inhibit melanogenesis and combat oxidative damage from UV and environmental exposure. Dermatologically tested and certified non-irritant, suited to all skin types.
Winner of the 2022 Australian Brand Awards for Product Innovation.

This is quite possibly the best product I've ever used on my eyes. The product is light and non-greasy. My eyes are firmer and brighter and the results were almost immediate! I 100% recommend this product!
I love that this product is safe for your face and your eyes. It is a light feeling Serum that in my way shape or form feels really like other serums that leave you feeling oily!
