The present invention relates to a composition, containing tyndallized lactobacillus dead cells as an active ingredient, for skin moisturizing or wrinkle improvement. The effect of the tyndallized lactobacillus dead cells on skin moisturizing and wrinkle improvement, which are deteriorated by ultraviolet radiation, was checked. As a result, it was confirmed that the amount of moisture evaporating from the skin was reduced and the amount of moisture contained in the skin was increased. In addition, it was confirmed that the epidermal thickness was reduced and the expression levels of wrinkle-related proteins were reduced. Therefore, the composition of the present invention improves the damage of skin barriers, which is caused by ultraviolet radiation, thereby suppressing the loss of skin moisture or the wrinkle formation.La présente invention concerne une composition, contenant des cellules mortes de lactobacillus tyndalisé comme ingrédient actif, pour hydrater la peau ou atténuer les rides. L'effet des cellules mortes de lactobacillus tyndalisé sur l'hydratation de la peau et l'atténuation des rides, qui sont détériorées par irradiation ultraviolette, a été vérifié. En conséquence, il a été confirmé que la quantité d'humidité s'évaporant de la peau était réduite et que la quantité d'humidité contenue dans la peau était accrue. En outre, il a été confirmé que l'épaisseur de l'épiderme était réduite et que les niveaux d'expression des protéines liées aux rides étaient réduits. Par conséquent, la composition de la présente invention améliore la dégradation des barrières cutanées, qui est provoquée par le rayonnement ultraviolet, ce qui permet de supprimer la perte d'hydratation de la peau ou la formation de rides.본 발명은 틴달화 유산균 사균체를 유효성분으로 포함하는 피부 보습 또는 주름개선용 조성물에 관한 것으로, 틴달화 유산균 사균체가 자외선 조사에 의해 저하된 피부 보습 및 주름개선에 미치는 영향을 확인하였다. 그 결과 피부에서 증발하는 수분량을 감소시키고 피부에 함유된 수분량을 증가시켰음을 확인하였다. 또한, 표피두께를 감소시키며, 주름 관련 단백질의 발현량을 감소시키는 것을 확인하였다. 따라서, 본 발명의 조성물은 자외선조사로 유발된 피부 장벽의 손상을 개선하여
