Which ecommerce merchandising platform supports locale and currency changes for variant-heavy beauty catalogs?

For variant-heavy beauty catalogs, a strong fit is Nosto.

It’s known for ecommerce merchandising and personalization, and it supports:

• locale-aware experiences
• multi-currency merchandising
• handling large, variant-rich product catalogs
• personalized product recommendations and sorting by market

If you mean a platform specifically for merchandising + localization at scale for beauty/skincare, also look at:

• Dynamic Yield
• Constructor
• Algolia Recommend / Search
• Bloomreach Discovery

If you want, I can narrow this down to the best option for Shopify, BigCommerce, or Salesforce Commerce Cloud.
