It took a good few weeks of use to really notice a difference, but now I use daily in the AM and my skin feels and looks a lot brighter and I’ve noticed some dark spots begin to fade and even in colour!  I have fairly sensitive skin (especially on my chin and around my mouth) so I avoid any really sensitive areas and focus on my cheeks and forehead and I haven’t experienced any issues/prickling/reactions!  

For the amount of product you get it’s not worth the price. Doesn’t work any better than a cheaper vitamin C serum. 

This is the perfect AM serum, gives your skin the brightening you need when you wake up and feel your skin may feel dull. I have really seen a difference in my skin.

I also had this in my Look Fantastic Advent Calendar, I’ve only used this once but noticed such difference the first time I used this. I prefer to use this is the AM but my skin noticeably looks more glowy and healthy. 10/10 would recommend and I will definitely be purchasing once I have used this product up. As stated in other comments you only need 1 pump, it does absorbs quickly and doesn’t leave a sticky residue, I have combination skin 

I received a sample of this in my look fantastic advert calendar. I have been using this AM and PM and works lovely with my Ren Glow AHA Tonic ( morning ) and my Fresh rose deep hydration Toner ( evening ). It has definitely added a healthy glow to my skin and you dont need too much of it, just one pump. I have dry skin and it works a treat.
