Based on the results of this study we propose a solution for treating existing stretch marks with an active ingredient of plant origin.

What is the most suitable strategy for stress proteins in cosmetics? / Christine Jeanmaire in IFSCC MAGAZINE, Vol. 6, N° 3 (07-08-09/2003)

[article]  inIFSCC MAGAZINE > Vol. 6, N° 3 (07-08-09/2003) . - p. 221-226 Titre : What is the most suitable strategy for stress proteins in cosmetics? Type de document : texte imprimé Auteurs : Christine Jeanmaire, Auteur ; Vincent Bardey, Auteur ; Louis Danoux, Auteur ; Philippe Moser, Auteur ; Philippe Moussou, Auteur ; Gilles Pauly, Auteur Année de publication : 2003 Article en page(s) : p. 221-226 Note générale : Bibliogr. Langues : Anglais (eng) Tags : Cytoprotection  'Heat  shock  proteins'  Pollution  Skin  'Skin  defense'  Stress  UV Index. décimale : 668.5 Parfums et cosmétiques Résumé : Under various stress conditions, heat shock protein expression is enhanced in cells. Working on skin pieces, two of the major skin-expressed heat shock proteins, HSP72 and HSP27, were visualized by immunohistochemistry after several stress conditions (UV, pollutants, thermal shocks) and the heat shock protein expression quantified in the epidermis. A strong increase of the epidermal heat shock protein expression, due to these different stresses, was observed. The most suitable cosmetic strategy is discussed: does one need to prevent or to favor heat shock protein induction in cutaneous cells? A prevention strategy is suitable in the case of acute stress, such as severe UV exposure that provokes cell damage and a strong induction of heat shock proteins. It is demonstrated that, using a photoprotective active ingredient Sunactyl®, suppression of the heat shock protein expression of cells is linked to a protection of the cells against UV induced damages. An induction strategy is appropriate for chronic daily stress from various sources. Seeing that a small and controlled induction of heat shock proteins in the skin speeds up the response and enhances the cellular resistance to further stress, HSP-Balance® was developed, which boosts the heat shock protein induction in the skin under stress conditions.
