his serum goes on easily and soaks in to my skin quickly. You don't need to use alot just a little. I purchased this serum because of the quality ingredients which are anti-aging such as stable vitamin C and hyaluronic acid. Both of these things are recommended by Dr. Oz to help look your best! The vitamin C also works synergistically with sunscreen SPF. Simply apply prior to putting on your sunscreen and it will amplify the protection from your usual sunscreen. I'm tempted to try other Mad Hippie products are using this serum!
