<p>The present invention relates to a cosmetic product which induces a change in color and of which the expiry date can be confirmed by the change in color, wherein anthocyanin, chocoberry extracts, aronia concentrates, and vitamin C are contained in a component constituting the cosmetic product, and the expiry date thereof can be confirmed through the anthocyanin, chocoberry extracts, aronia concentrates, and vitamin C. According to the present invention, a user can be induced to easily identify the expiry date of a cosmetic product through a change in color, such as the partial or overall discoloration, decolorization, and coloration of cosmetic product contents by means of an anthocyanin component which is a natural pigment which can be used for a cosmetic product and causes a change in color and vitamin C which has strong acidifying properties and causes a change in color. Accordingly, damage caused when an expired cosmetic product is used can be prevented. Moreover, the time of a change in color can be adjusted by different components having sulfurizing effects, so that various expiry dates can be confirmed.</p> |
