1. Discontinuation: Shiseido's Yue Wei Pfeiffer emulsion was discontinued, resulting in many things being out of stock.
2. Brand strategy: Shiseido may adjust its product line according to market performance, product life cycle and other factors, so as to eliminate some products with poor performance.
3. Copyright issue: If Shiseido fails to reach an agreement with the relevant copyright parties or there are infringement issues, it may also lead to its removal from the shelves.
The above are only possible reasons, and the specific reasons need Shiseido official announcement or related news reports.
