I use Pentaxyl on my neck with the Lumiere De Vie Firming Neck Cream, they both work well together on my neck. You can feel it warms up when you massaging it into your skin because this product goes beneath the skin to the second layer of your skin. I use it as well as a hand cream & you can tell the difference how your skin firms up.
