Abstract: Polypeptides belonging to the family of late proteins of the cornified envelope (LCE), fragments of the polypeptide, isolated nucleotide sequences encoding the polypeptides, and cosmetic and/or pharmaceutical compositions containing such polypeptides are described. The polypeptides have cosmetic and/or therapeutic use to reinforce the barrier function of the epidermis, prevent and/or treat the signs of skin dryness and prevent and/or treat disorders of the barrier function or the weakening of the epidermis.

The polypeptides have cosmetic and/or therapeutic use to reinforce the barrier function of the epidermis, prevent and/or treat the signs of skin dryness and prevent and/or treat disorders of the barrier function or the weakening of the epidermis.

Abstract: A novel polypeptide isolated from the cornified envelope, similar polypeptides and fragments of the polypeptide, isolated nucleotide sequences encoding the polypeptides, as well as a cosmetic and/or pharmaceutical composition containing such polypeptides are described. The polypeptides have cosmetic and/or therapeutic use to reinforce the barrier function of the epidermis, prevent and/or treat the signs of skin dryness and prevent and/or treat disorders of the barrier function or the weakening of the epidermis.

Abstract: A novel polypeptide isolated from the cornified envelope, polypeptides similar to the latter or fragments of the polypeptide as well as a cosmetic and/or pharmaceutical composition containing same are described. The mainly cosmetic and/or therapeutic use of the polypeptide, or similar polypeptides or fragments of the amino acid sequence of the polypeptide, or an encoding nucleotide sequence for the polypeptide, to reinforce the barrier function of the epidermis and prevent and/or treat the signs of skin dryness or prevent and/or treat disorders of the barrier function or the fragilisation of the epidermis. Finally, the isolated encoding polynucleotide for the polypeptide are also disclosed.
