Puffy eyes are commonly a result of irritation. 1. If the product you are using for the eye area does not say "eye" anywhere on it, you are irritating it because the product was not designed for your eye area (the most sensitive skin on your face). 2. Placing any kind of product to close to your eye, regardless of what the product says irritates your eye because the product will slide into the eye instead of treating the surrounding areas that are effected. Resulting in Puffy Eyes.
