What this is
The Undercurrent is not a newsletter. It is a quarterly diagnosis of the prestige beauty, fragrance, and wellness category, written from the same methodological foundation that drives every Skaggs engagement.
Every Brand Worth Watching entry is diagnosed once and then tracked every quarter that follows without exception. When a brand moves, we say so. When nothing moves, we say that too. The archive is not a record. It is a running diagnosis.
AI researches it. We interpret it. That is the operating principle behind every issue.
