Clear Skin Smoothies-Do they really work?

I'm all about eating fruits and vegetables but does stuffing "superfoods" into a blender and grinding it into a liquid really make skin glow?

Will it really change my skin from this?

To this?

Probably not! Will drinking clear skin smoothies for seven days make a difference at all?

The Strawberry-Banana smoothie promises that the vitamin C from the strawberries is a natural collagen builder. Where the Berry Blast Smoothie claims to protect skin from harmful pollutants with the help of antioxidants, and the Fruit Fusion Smoothie is said to help prevent blemishes and is filled with anti-aging antioxidants like vitamin C and E and promises to leave skin glowing. Also, there is zinc in this smoothie which claims to help heal rashes and reduce inflammation. I have Psoriasis and my knees are typically swollen so I hope this information is true.

Won't you join me in this seven day smoothie experiment to see if clear, glowing skin is a possibility?
