Love it
Love the smell and consistency of this serum. Very lightweight, instantly absorbs and leaves a nice glow on the skin. Faint smell of citrus and the serum is completely clear.

Love this stuff
First received a smaller version of this in my LF advent calendar and it's a dream - I use it once a week and it makes my skin feel smooth, hydrated and it smells lovely. Doesn't irritate my sensitive skin. Avoid using near eyes but otherwise this is perfect and a little goes a long way!

On the fence
Nice smell. Didn’t see any results from use. Not a fan of the texture/ feel of this on skin. A bit oily/greasy but it doesn’t stay greasy it does sink in.
