About

Extracellular vesicles isolated from green tea (Camellia sinensis) leaves, used as natural lipid-based carriers for skincare actives.

Camellia sinensis leaf vesicles are lipid bilayer structures from green tea leaves, naturally carrying tea polyphenols, caffeine and membrane proteins. Green tea extract is extensively regulated and approved globally; in the EU, it appears in Annex III with a limit for catechins when used for hair dyeing purposes. For leaf vesicles used as delivery vehicles (not dyeing), no specific restriction applies. The ingredient is considered safe with a long history of use of green tea in cosmetics.

Skin benefits

  • Natural carrier for tea-derived antioxidants (EGCG, catechins)
  • May improve penetration of co-formulated actives
  • Antioxidant and anti-inflammatory properties inherited from green tea

Known concerns

  • Green tea catechins may cause sensitization in rare cases
  • Novel delivery format requiring standard cosmetic safety assessment
