Exact science-based dupes appear first. When a strict dupe is not available yet, we still show the closest active-match alternatives from the same product category.

Benton · drugstore
Actually shares niacinamide plus both signature peptides (palmitoyl tripeptide-1 and tetrapeptide-7), making it the closest active match, though it adds snail mucin and lacks the hyaluronic acid/lactate humectant blend.
No price

rhode · drugstore
Shares niacinamide but uses a different single peptide (palmitoyl tripeptide-8) instead of the source's palmitoyl tripeptide-1/tetrapeptide-7 combo, and lacks the lactate/amino acid moisture complex.
No price

Caudalie · drugstore
Only overlaps on niacinamide; its peptide actives are grape-derived (palmitoyl grape seed/grapevine extracts), not the same peptides as the source, and it adds fragrance allergens.
No price

Glow Recipe · drugstore
Shares niacinamide and hyaluronic acid but has no peptides at all, relying instead on fruit extracts and silicones for glow/texture.
No price

Beauty of Joseon · mid-range
Only shares niacinamide; it's propolis-focused with no peptides, urea, or lactate humectant system found in the source.
No price
We rank results with INCI-level analysis first, then fall back to the strongest active matches and closest alternatives so every product page still shows comparable options. Fallbacks stay within the same category as the source product, so cleansing balms only surface cleanser dupes instead of adjacent product types. Active Match % measures shared science-backed actives. Formula Similarity % measures total ingredient overlap when full INCI lists are available.
