I have read an interesting article at
http://caracolcreams.com/explaining the difference between snail slug and extract. Studies have
demonstrated that the snail extract is the only one which works
reducing wrinkles and healing acne, scars and other skin injuries.
Snails use slug only to move. It doesn't have any healing properties.
Caracol Cream is made with snail extract and you can get a 1 days free
