Have you ever noticed faint lines across your skin after a good night’s sleep? When you’re young, folds or indents made from your pillow or mattress fade quickly. But as you grow older and your collagen levels start to decline, you may notice those lines stick around. So what can you do about it? By naturally supplying your body with collagen, you can enhance your skin’s texture and elasticity, allowing it to bounce back after a night of deep sleep.
