Third Night Nerium AD

Well, this is the third night using the Nerium AD.  The first night my face felt extremely tight, like it was drawing up.  Last night, not so much.  Tonight I didn't add as much water as last and my skin feels much like it did the first night.  Not seeing a difference but it's still early.  We'll see I guess.  Still worrying about long term effects, if any.  So many reviews, some good and some bad.
