This must be my favourite The Ordinary product. It is such a lightweight hydrator and it always calms down my skin. The smell can be unpleasant at first but it fades away quite quickly.

I have dehydrated skin and this product helps to diffuse heavier hydrating creams so they absorb better and faster.

Given its price, this serum does work. The not-so-pleasant scent and the feeling of residue left while applying it on your face would be the downsides but on the plus side it is very lightweight, doesn't cause outbreaks and it does leave your skin hydrated, looking pretty the next morning. Overall, it works!

Unfortunately this smells terrible - a bit like puke. I also found it a bit light for my skin and dont feel like it does much. First Ordinary fail for me as I generally love their stuff, I prefer the normal hyaluronic acid which is great.

It smells just like vomit. Good moisturising.
