BIOLOGI
Founded in 2017, Biologi is a profoundly different approach to skincare that delivers unheard of results. Australian based, made and owned, we are entirely accountable for the production process and lifecycle of our products - from plant to bottle to pore.
You can use Bk serum to target the delicate eye area and face. Be careful not to layer the serums as the actives from each extract work synergistically as they do in the plant so combining the actives could have a negative effect and your serums may not work as well.
Vitamin C is a natural active found in fruits such as oranges, lemons, and Kakadu plum (Bk serum). Ascorbic acid is a synthetic product made by scientists in a lab. Vitamin C is notoriously unstable when exposed to air or water, and ascorbic acid adds synthetic stabilisers to vitamin C extracts, so it can be used in skincare products.
The vitamin C naturally occurring in Bk Face & Eye Serum is extracted using a revolutionary system that keeps the key phytonutrients intact. Unlike synthetic forms of vitamin C such as ascorbic acid, L-ascorbic acid and d-ascorbic acid that are created in a labhehe tha. While popular theories state that ascorbic acid and sodium benzoate react to create benzene – a known carcinogenic – it’s impossible for the plant vitamin C extracted to make our water-soluble serums to cause this reaction because we don’t add synthetic ascorbic acid to our products.
Yes, Bk Face & Eye Serum contains phyto-actives and nutrients which are excellent in strengthening the immunity of the skin, helping to protect, repair and brighten it. We recommend pairing the Bk Serum it with our Br Rosehip Oil for scarring for its added benefits with scarring concerns. For a customised regime, please reach out to our qualified skin experts.
