Query: I swear this GAVE me wrinkles

I had very few wrinkles around my eyes so I decided to try this to get rid of them. Within a few weeks I had a LOT of wrinkles around my eyes and especially under my eyes! I have no idea what in the world happened. My mother hardly has any wrinkles and my sister (who is 13 years older than me) doesn't either. I don't get what happened at all but I'm very upset about the results.
