The present invention relates to the field of cosmetics or pharmaceuticals, and particularly to the dermatological field. In particular, the present invention relates to particles containing hyaluronic acid, modified by hydrophobic groups, and to the use of said particles as an agent for stimulating the epidermis and/or dermis. In particular, said assemblies are useful as a moisturizing and/or plumping and/or volumizing agent. Said particles, which contain hydrophobized hyaluronic acid, are also useful for reactivating endogenous hyaluronic acid expression, thereby making it possible to reduce and/or prevent skin imperfections, for example, by filling in wrinkles and lines. |
