Snail Bee High Content Essence

Active MatchTop 3 actives align
Active Match: 60%Formula Similarity: 19%

Actually matches niacinamide and Palmitoyl Tripeptide-1 like the source, plus similar humectants (glycerin, butylene glycol, panthenol, allantoin, aloe), though it adds snail mucin and extra peptides not in the source.

Peptide Glazing Fluid

Closest Alternative
Active Match: 57%Formula Similarity: 30%

Shares niacinamide but the source's real hero is its multi-humectant/amino acid blend (sodium lactate, serine, urea, sorbitol) plus panthenol and a peptide, none of which this fluid replicates beyond a different single peptide.

⚠ different peptide (Palmitoyl Tripeptide-8, not -1)⚠ lacks urea/lactic acid/amino acid humectant complex⚠ no botanical waters

Premier Cru Le Sérum

Closest Alternative
Active Match: 57%Formula Similarity: 14%

Shares niacinamide and hyaluronic acid but pivots to Caudalie's grape-derived peptides instead of the source's palmitoyl tripeptide-1 and lacks the urea/lactic acid/amino acid humectant blend.

Watermelon Glow Niacinamide Dew Drops

Closest Alternative
Active Match: 57%Formula Similarity: 21%

Only real overlap is niacinamide and glycerin; this is a watermelon/fruit-extract hydration serum with silicones and pigments, missing the peptide, amino acids, and multi-humectant system that define the source.

Closest Alternative

Shares niacinamide and some humectants (glycerin, hyaluronic acid, panthenol) but is built around propolis and adenosine rather than the source's peptide and amino acid/urea humectant complex.

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.
