The vitamin C serum that actually lasts.Most vitamin C breaks down within weeks, long before the bottle is empty. C E Peptides is built differently. It pairs the purest pharmaceutical-grade vitamin C with Vivier's IntraDermal System, which keeps it stable and helps it absorb deeper, then adds vitamin E and three peptides to firm and smooth while the vitamin C brightens. Over time skin looks clearer, more even, and more awake.Why it is worth itThis is the serum Vivier is best known for, and the stability is the difference: you get active, effective vitamin C for the life of the bottle, not just the first few weeks. It is also vegan and cruelty-free.How it comparesIf your skin is sensitive or new to vitamin C, Serum 10 is the gentler entry point. If you want the strongest anti-aging correction, GrenzCine Serum is the step up. C E Peptides is the daily gold standard for normal to dry skin.Best for: normal to dry skin wanting brighter, firmer, more even skin.Not ideal for: very sensitive or very reactive skin (try Serum 10).How to useApply 2 to 3 drops to clean, dry skin morning and night, then moisturizer. Always wear sunscreen during the day.
