This serum has a cooling roller head with which you apply it. When applying, you twist the entire top to open and then squeeze the tube. The serum is released through the cooling roller head, and I have to say it feels great. Even when there isn't serum on the roller head, it feels cooling and soothing to roll across your face. My only gripe with this is I can't tell how much serum I am putting on my face, since I can't see it coming it out and the serum is released by me squeezing on the tube. I can't help but feel I'm probably using more than I need to. Is this the Elixir of youth, probably not, but it feels good.

I love how it feels, such a great cooling effect.

This might be my favorite product. It rolls on smoothly and then you just have to tap it in with your fingers. It smells great and I love it.

Noticed my neck responded to this quickly. Cooling and soothing! 

Great product, I like how it absorbs quickly.

I would highly recommend NO7 Intense Replenish serum. I'm premenopausal and my skin is so dry. After using this product for a week my skin is no longer dry. My skin looks radiant.

I love this product. It is refreshing and the roller makes it very easy and relaxing to use. I give it a 10 out of 10.

This is such an awesome product! It is super easy to use everyday. It really works on my skin and feels so good while it is on my skin.

I loved the rollerball application. It feels cool going on and I always love the idea of using a roller but 100 times better while applying with serum! #7 Worked well and it is a product I would buy.

I'm 56 yrs old and I totally love this product. Nice fragrance and not heavy feeling. I would definitely recommend this product!
