How to cover dark circles with concealer

Before painting dark circles with concealer, you must first apply moisturizing eye cream in the order of lower eyelid, upper eyelid and outer corner of eye. Wait until the eye cream is completely absorbed, and then observe your eyes carefully. The upper eyelid sometimes has pigmentation or red blood, and the lower eyelid sometimes has obvious dark circles, which will make the eye makeup look dirty, so it should be covered with special eye concealer. Usually, the ingredients of eye concealer products will contain some eye care ingredients, such as chamomile, angelica essence with moisturizing effect, Ginkgo biloba extract to improve eye skin metabolism and so on.

Usage: When using the eye mask, put it on the palm of your hand first. After the skin temperature "melts" the concealer slightly, the texture will become thinner and smoother to use.
