AGENTS Photoprotective, CYTOPHOTOPROTECTEURS SKIN WITH photoprotective activity CONSTITUENT CELLS FUNCTIONAL SKIN, ESPECIALLY CELLS Langerhans, BASED COMPOUNDS NUCLEIC: NUCLEOPROTIDES, ribonucleotides and deoxyribonucleotides, ribonucleosides and deoxyribonucleosides, COSMETIC OR DERMO-PHARMACEUTICAL CONTAINING SUCH AGENT AND NEW COMPOUNDS IN ITSELF

摘要

The invention relates to a photoprotective agent and cytoprotective skin. This agent is characterized in that it comprises at least one compound chosen from the group of compounds and nucleic derivatives. comprising: A - nucleoprotides, in particular ribonucleic acids, and their derivatives, their salts, with inorganic or organic bases and preferably complex salts of basic proteids; basic amino acids or basic peptides; or deoxyribonucleic acids or their derivatives, in particular salts with inorganic or organic bases, or better the complex salts of deoxyribonucleic acids with basic proteins, basic amino acids or basic peptides; B - Ribonucleotides and deoxyribonucleotides and their salt derivatives, with mineral or organic bases including complex salts with basic proteins, basic amino acids or basic peptides; and C - ribonucleosides and deoxyribonucleosides. It is thus possible to prepare cosmetic and / or dermopharmaceutical compositions for topical use having a photo-protective activity of the integuments, but more particularly of living cells of the dermis and epidermis, thus resulting in a cutaneous cyto-photo-protection, in particular immuno-competent cells of the epidermis: Langerhans cells, sensitive not only to solar radiation, but by contact with certain compounds frequently used as sunscreens. / P
