Detailed answer

When the skin lacks hydration, it becomes dehydrated and loses its elasticity. This can lead to a breakdown of collagen and elastin, which are proteins responsible for keeping the skin firm and supple. Without proper hydration, the skin becomes less plump, dry, and prone to sagging. Additionally, dehydration can also worsen the appearance of existing fine lines and wrinkles. It is crucial to maintain a well-hydrated skin through adequate water intake and using moisturizers to help prevent sagging and maintain a youthful complexion.
