Is the SkinCeuticals C E Ferulic a real dupe?
It shares hero actives with 2 same-category products in our catalogue, most closely the Drunk Elephant C-Firma Fresh Day Serum (matching 3 of 3 of its hero actives). "Dupe" here means shared key ingredients, not an identical formula.
Does matching more hero actives make it better?
No. The match count only shows how many hero actives are shared. The base, supporting ingredients, texture and price still differ, so use the side-by-side comparison for the full picture.
