serum sensation!

Love the serum. Not sticky and does leave a heavy film like other serums do. 👍

Great product

I have been using this for about 1 week and notice that my skin is definitely happier. I have Rosacea and always have problems with products. This product seems to calm my skin down.

HOW TO GET THE MOST OUT OF YOUR CAIRE EXPERIENCE

Watch our How To Guide to learn how to use the Theorem Serum Boost.

This is skin joy in a bottle!  I love putting the serum on my hands since it feels so hydrating and I wear surgical gloves everyday.

~ Tonya, Age 53

Here's the Proof:

"I love the Caire Serum, I've been using it now for a few months. I use it twice a day and I noticed immediately that my skin has aglow. It feels soft and nourished. And while I love the immediate benefits, I also know that it's regenerating for my skin long term. As I'm aging, I realize that there's more than I need to do to make sure that my skin is healthy and moisturize. And I know the care beauty is doing that work in the short term and in the long term."

~ Kim C.
