A niche brand targets a small, well-defined segment of customers. Niche brands discussed in the document include luxury fragrance brands like Serge Lutens and Frédéric Malle that offer unique, high-quality scents through selective distribution. Niche cosmetics brands focus on natural and organic ingredients to serve specific customer needs, such as Doux Me skincare or Amazonia Viva's botanical products from the Amazon rainforest. Niche status is not defined by sales size alone but by a brand's specialization and ability to meet the needs of its narrow target market.
