Skincare Dupe Dominance: Retail Surge
The only article is a consumer how-to guide on finding skincare dupes that work. It shows dupes are still a mainstream consumer topic, but it gives no market share data, retailer own-brand sales figures or premium brand performance numbers. Nothing in it matches the falsification criteria (premium brands holding or growing share, or own-brand dupe sales stagnating), and nothing confirms dupes are taking share at retail, so the evidence is too thin to call either way.
What would prove this wrong
This is disconfirmed if premium skincare brands hold or grow market share and supermarket own-brand dupe sales stagnate or decline over the period.
