Is the Medik8 Crystal Retinal 6 a real dupe?
It shares hero actives with 1 same-category product in our catalogue, most closely the Estée Lauder Advanced Night Repair Synchronized Multi-Recovery Complex (matching 2 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.
