The Ordinary makes active ingredient skincare at prices that make it irrational not to use them — 23% Vitamin C concentration at a price where you can use it generously without consideration. Brightens skin tone, provides antioxidant protection against environmental damage, and supports collagen synthesis. The entry point into evidence-based skincare.
Drunk Elephant's Vitamin C serum uses a 15% L-ascorbic acid concentration alongside ferulic acid and vitamin E, which stabilise the Vitamin C and multiply its effectiveness. The fresh-mix packaging means the actives are genuinely potent when you use them rather than degraded by months on a shelf. The serum that converts people to vitamin C.
Augustinus Bader is the stem cell researcher who developed a burn treatment for the German government and adapted the technology for skincare. The TFC8 complex triggers the skin's own repair mechanisms rather than applying topical ingredients — it works differently from any other product in the category. Used by plastic surgeons post-procedure. The premium that's justified by a genuinely novel approach.
