Cosmetic product for topical use for protecting and renewing skin stem cells derived from dedifferentiated plant cells

摘要

Cosmetic product (I) comprises at least an active agent derived from dedifferentiated plant cell suspension, where the agent protects stem cells against intrinsic and extrinsic stress factors. An independent claim is included for the preparation of an extract from the suspension, comprising digestion of plant cells obtained by high pressure homogenization and extraction and stabilization of ingredients with liposomes, where both these two steps are carried out simultaneously in a single step.
