Chapter One: Hydration
The healthy outer layer of skin should contain 12-15% water. Skin that is sufficiently hydrated looks plump and is not only soft and smooth, but also feels elastic, radiating youthful brilliance. However, once it lacks water, in addition to dryness and roughness, fine wrinkles will appear, and youth will be gone forever. So don't be careless about it. From this, we can see how important hydration is. To have a good skin full of moisture, start taking action now.
