Do not buy Skin-eze. The company is not credible! They do not accept returns! They know their product is not any good and therefore they do not provide any refunds! Please take this warning! Do not do business with them! They will not take back any product that is opened. Well how do you know if it works, if you don't open it! They know when you open it, you won't like it! Not only did it not work, but it tasted horrible and made my dog sick! But I can't return it because it was opened!
