Abstract
An ultraviolet protection patch is provided. An ultraviolet protection patch, according to one embodiment of the present invention, is implemented by comprising: an ultraviolet protection layer including a support component and an ultraviolet protection agent; and a first shape-retaining layer which is a fiber web provided on one surface of the ultraviolet protection layer. According to this, as the ultraviolet protection patch comprises the ultraviolet protection layer and the shape-retaining layer which have predetermined properties, an ultraviolet protection material does not directly contact the skin, and thus skin trouble, irritation, and white cast do not occur, and as the patch is excellent in elasticity, the patch has excellent stiffness without inhibiting movement of a site to which the patch is adhered or peeling off even by physical stimuli, and the ultraviolet protection layer and the shape-retaining layer have a predetermined basis weight relationship, thereby having excellent transparency, and thus, there is an effect of not reducing visibility of the site to which the patch is adhered when the patch is adhered to the skin.
