\n Quand une \u00e9tude sur la barri\u00e8re cutan\u00e9e atterrit sur votre bureau, regardez la mesure prise juste apr\u00e8s le d\u00e9fi, avant l'application de la cr\u00e8me. Le site pr\u00e9sentant une perte d'eau plus faible lors de la visite finale peut avoir commenc\u00e9 avec moins de perturbations.<\/span> Si les deux sites ont commenc\u00e9 leur r\u00e9tablissement \u00e0 partir d'un point similaire, les mesures entre ces deux visites peuvent montrer si l'un est revenu plus rapidement vers la valeur de r\u00e9f\u00e9rence.\n <\/p>\n

\n Que s'est-il pass\u00e9 lorsque la base a \u00e9t\u00e9 test\u00e9e en parall\u00e8le avec la cr\u00e8me ?\n <\/h2>\n \n

\n Proksch et Nissen (2002) ont utilis\u00e9 du laurylsulfate de sodium pour irriter la peau des avant-bras de volontaires. Un site a re\u00e7u une cr\u00e8me \u00e0 base de dexpanth\u00e9nol et un autre a re\u00e7u la base de cr\u00e8me. Au cours de la semaine suivante, les chercheurs ont mesur\u00e9 l'hydratation de la peau et la perte d'eau trans\u00e9pidermique (TEWL). L'hydratation s'est am\u00e9lior\u00e9e par rapport \u00e0 la base, et la TEWL \u00e9tait plus faible lors de certaines visites de suivi.<\/span>\n <\/p>\n \n

\n La base m\u00e9rite sa place dans cette \u00e9tude car la peau irrit\u00e9e peut se r\u00e9tablir avec le temps, et l'application de la base peut influencer les mesures. Un simple test avant et apr\u00e8s sur la cr\u00e8me de dexpanth\u00e9nol aurait regroup\u00e9 ces effets. L'article a test\u00e9 le D-panth\u00e9nol. Si le laboratoire travaille avec du DL-Panth\u00e9nol, la comparaison est utile \u00e0 emprunter. Les donn\u00e9es de performance doivent provenir de la formule et de la qualit\u00e9 que l'\u00e9quipe pr\u00e9voit d'utiliser.<\/span>\n <\/p>\n\n

\n Une mesure de TEWL plus faible peut signifier diff\u00e9rentes choses\n <\/h2>\n \n

\n Une cr\u00e8me peut ralentir la perte d'eau tant que son film est sur la peau. Si le laboratoire mesure la TEWL peu de temps apr\u00e8s l'application, le r\u00e9sultat peut refl\u00e9ter ce film. C'est une mesure utile si la question est de savoir quelle quantit\u00e9 d'eau s'\u00e9chappe pendant que le produit est port\u00e9. Pour une all\u00e9gation de r\u00e9tablissement, recherchez les mesures avant le d\u00e9fi, imm\u00e9diatement apr\u00e8s et \u00e0 plusieurs points pendant le r\u00e9tablissement.<\/span>\n <\/p>\n\n

\n V\u00e9rifiez le temps \u00e9coul\u00e9 depuis la derni\u00e8re application lorsque vous lisez le rapport. Une mesure prise peu de temps apr\u00e8s l'application d'une cr\u00e8me et plusieurs heures apr\u00e8s l'autre rend la comparaison difficile \u00e0 interpr\u00e9ter. Le lavage r\u00e9cent, les r\u00e9sidus de produit, les conditions ambiantes et l'acclimatation peuvent \u00e9galement affecter les mesures (du Plessis et al., 2013).\n <\/p>\n\n

\n Un brief indiquant \"hydrate pendant plusieurs heures\" n\u00e9cessite une mesure d'hydratation \u00e0 l'intervalle indiqu\u00e9. Si l'all\u00e9gation concerne la sensation de tiraillement apr\u00e8s le nettoyage, demandez aux personnes comment leur peau se sent tendue apr\u00e8s la m\u00eame routine de nettoyage et d'application. Des mesures d'hydratation similaires peuvent correspondre \u00e0 diff\u00e9rentes impressions de confort.<\/span>\n <\/p>\n\n

\n Gardez la comparaison proche de la d\u00e9cision\n <\/h2>\n \n

\n Lorsque la question est de savoir si le panth\u00e9nol m\u00e9rite une place dans la formule, pr\u00e9parez un lot de la m\u00eame base sans lui. Gardez la phase huileuse et les autres humectants comparables. Si la pr\u00e9paration de panth\u00e9nol contient de la glyc\u00e9rine, incluez cette contribution lorsque vous calculez la glyc\u00e9rine totale dans le lot d'essai. Le contr\u00f4le doit avoir le m\u00eame total si vous voulez isoler l'ajout de panth\u00e9nol.<\/span>\n <\/p>\n\n

\n La cr\u00e8me que vous vendez d\u00e9j\u00e0 est une r\u00e9f\u00e9rence utile lorsque vous d\u00e9cidez de la remplacer. M\u00eame si plusieurs ingr\u00e9dients ont chang\u00e9, une comparaison peut vous dire quelle cr\u00e8me finie r\u00e9pond mieux au brief. Si l'\u00e9quipe souhaite \u00e9galement savoir si le panth\u00e9nol a contribu\u00e9 \u00e0 l'am\u00e9lioration, incluez la base appari\u00e9e dans l'\u00e9tude.\n <\/p>\n\n

FAQ<\/h2>\n \n
\n
Puis-je signaler une TEWL plus faible apr\u00e8s une seule application ?<\/div>\n
Oui. Incluez le temps apr\u00e8s l'application et les conditions de test. Une all\u00e9gation de r\u00e9tablissement n\u00e9cessite un contr\u00f4le appropri\u00e9 et des mesures de suivi apr\u00e8s un d\u00e9fi d\u00e9fini.<\/div>\n <\/div>\n\n
\n
Que se passe-t-il si l'hydratation s'am\u00e9liore mais que la TEWL reste similaire ?<\/div>\n
Signalez l'am\u00e9lioration de l'hydratation. Dans ces conditions de test, les mesures de TEWL n'ont montr\u00e9 aucun changement clair dans la perte d'eau.<\/div>\n <\/div>\n\n
\n
Que dois-je demander \u00e0 un fournisseur de panth\u00e9nol avant de tester ?<\/div>\n
Demandez le COA de lot et la fiche technique. V\u00e9rifiez la forme D ou DL, la base de dosage et tout support. Enregistrez la qualit\u00e9 et le num\u00e9ro de lot avec la formule d'\u00e9tude afin de pouvoir retracer le r\u00e9sultat jusqu'au mat\u00e9riau utilis\u00e9.<\/div>\n <\/div>\n <\/div>\n\n
