With the advent of ingredient permeability and micronisation of active ingredients in skincare, the common belief is that serums are our only topically applied options for optimal penetration of actives. However, new studies confirm that the key factor to skin penetration is the nature of the chemistry of the delivery system. Dr Donna Marcal holds a PhD in biochemistry and is a passionate educator in cosmetic ingredients and biotechnology. In this lecture you will learn:
- How skincare ingredients penetrate the skin and to what level
- New advances in skincare trans-epidermal delivery systems
- Can lipid-based actives be successfully included with water-based actives in the one formula
- What do the studies say about serums versus creams when it comes to the effective delivery of actives.
About Dr Donna Marçal
Dr Marçal is a specialist doctor in human Biochemistry from The University of Ottawa, Canada. Dr Marçal specialises in inflammation and how the body reacts to foreign materials. Her work has been published in numerous highly respected biomedical industry journals around the world.
Dr Marçal has been awarded several international research fellowships for her work including The Prime Minister’s Science Award from Australia, which facilitated her to continue the award-winning research program here in Australia. Upon her Sydney research visit, she investigated the human biochemistry pathways involved in inflammation and biomaterial responses using advanced proteomics techniques in collaboration with the Bioanalytical Mass Spectrometry Facility at The University of NSW (UNSW). Her work on specific human proteins and their functions in human inflammation awarded her an Endeavour Research Fellowship from the Australian Government. She has also worked with The Australian Institute of Bioengineering and Nanotechnology (Brisbane, QLD) on high profile projects. Dr Marçal then switched her focus to continue her work on macrophage-mediated inflammation in Atherosclerosis with the Macrophage Biology Group at UNSW in Sydney.
She continued her work in inflammation, cholesterol transport and cell signalling in macrophages before launching and becoming the driving force behind Dermatonics®. Her knowledge of human inflammation is central to the formulations behind each Dermatonics® skincare products in combination with her business partner and husband, Dr Helder Marçal. https://dermatonics.com.au/
