What can I use to get really pretty skin? And remedies for getting rid of dark, baggy eyes?

Eat better. Meaning lay off the processed foods and increase your intake in natural, organic foods. That's the best way to increase your collagen naturally without spending money on products that claim to do miracles. Look at the people from the past the way they lived without these products. It's because they ate right and did exercises everyday from the labor back then. Good luck.
