This product comes in a beautiful glass/ceramic bottle.  The product itself is supposed to work as a "finisher" which means you use this at the end of your skincare to seal in all the benefits of your regimine.  You can use this product morning and night, but I prefer to use this in the morning only.  I didn't find that it necessarily sealed in my skincare, but it acts as a great makeup primer!  If you like the glowy look, you will love this product, as it gives my skin a radiant look.  Also, it works excellent at keeping my makeup on longer, I definitely noticed a difference with that aspect.  Overall it is very pricey, but 1 pump dispenses the perfect amount.  I am very pleased with this product.
