Why Beauty Brands Use Sachets

Sachets are one of the most practical sampling and trial formats available to cosmetic and personal care brands. Key reasons brands choose sachet formats include:

  • Low-friction sampling — customers can try before committing to a full-size product
  • Travel and trial formats that suit gifting, subscription boxes and retail discovery
  • Launch campaigns with controlled, single-use portions
  • Retail discovery packs and multi-sachet trial sets
  • Salon and spa sampling without the cost of full-size testers
  • Lower barrier to customer testing before full-size production investment
