It has been a recurring habit by me tio sleep late and get up very early in the morning. This has led to my skin appearing to be dull and without any of its earlier vitality and cheerfulness.There have been dark circles that have started appearing around my eyes.the solution here is that i sleep well ,so that i get up feeling fresh and then automatically my skin tone will improve and appear healthy. My husband then told me to take the kava kava extract? Is there any other name for Kava Kava Extract ?What is the way in which you can take Kava Kava Extract to help you in inducing sleep?what are the precautions that should be kept in mind before using the Kava Kava Extract?
