This is probably the one product out of the whole range that I'm not completely sold on. Personally I felt like it didn't do much for my skin, and I found that it was the one product I didn't really care about using.
There's nothing actually bad about this product, however there's nothing I found to be amazing either. I felt like instead of nourishing my skin, it almost made it feel dryer than usual, and slightly tight. I personally do not like the tight feeling because it makes me feel like I'm just putting alcohol on my face.
What I do like about this serum is the packaging, I like how it's slightly heavy so it feels nice to hold. The pump is also nice, but I think if it was a bit more controllable it would be perfect.
I will definitely continue to use this serum though, because I think that all of the products in this range work together amazingly. Perhaps if I stop using it I will see a difference, and then I will know if it's helping my skin.
