The Story Behind CSA
At Medik8, we like to keep skincare simple. That’s why we invented the CSA PhilosophyⓇ all the way back in 2009.
“Years ago, my brother and I were looking in all the dermatology journals to find out if there was a way we could add some authenticity to skincare and demystify the noise around it…We found out that, ultimately, there is no secret – it’s about using these core ingredients that have been proven time and time again to deliver effective skincare results: vitamin C, sunscreen and vitamin A. But, of course, we knew these actives needed to be carefully handled to ensure the very best visible results. That’s why we set about creating the highest quality, no-compromise formulas which simultaneously deliver unparalleled clinical results, ethical values, and a luxury experience without irritation.‘’
