Stabilized vitamin C + ferulic acid for dullness and dark spots — brightening remains one of the highest-repeat categories in EU retail.
A stabilized vitamin C serum pairing 10–15% ascorbic-acid-complex actives with ferulic acid and vitamin E — the classic C-E-ferulic architecture that Western buyers associate with serious brightening. Targets dullness, uneven tone and post-blemish marks, the highest-repeat efficacy category in EU retail.
Stability is the historic weakness of vitamin C serums; ours uses a stabilised complex with chelators and an amber-glass or airless presentation to protect the active through shelf life and after opening.
Stabilised complex + ferulic/E antioxidant network, nitrogen-headspace filling on request, and amber glass or airless packaging.
15% sells to experienced buyers; 10% widens the audience and lowers irritation risk. Many brands launch both.
Yes — the Vitamin C Brightening Day Cream uses the same architecture and is commonly merchandised as a duo.
pH is tuned to the vitamin C system (low 3s); we supply a routine-positioning note explaining layering for your product page.
