su:m37 announces a fifth-generation Secret Essence
LG H&H's 8 October announcement identifies a renewed version of the brand's established essence.
Published
20 October 2026 — LG H&H announced on 8 October that su:m37 had renewed Secret Essence as a fifth-generation product. The company identifies the original launch year as 2009 and presents the new version within the brand's fermentation-focused positioning.
Read the generation as part of the name
The release describes formulation changes and cites manufacturer-reported performance tests. THE CAST has not independently tested the product, and this news brief does not turn those reported results into a general recommendation.
For shoppers, the immediate comparison is the exact version on offer. A familiar name may appear on an older package, a renewed package or a set containing other products. Compare the current ingredient information, net contents and directions rather than assuming continuity from the name alone.
Keep the source and seller separate
The official release documents the renewal. A seller's current page must establish availability and the selected option. THE CAST's essence, toner and serum guide helps frame those questions; this report does not claim that the renewed su:m37 product is available at THE CAST.
