Love love love !

I am a convert! Tried a fair bit of the range with the tester sizes ( such a great idea ) now settled on my favourites…Illume, Bak, Rosehip, Moisture but the absolute game change is the sunscreen!! How is my face not a greasy mess using all this, topped with sunscreen and then my usual makeup (Trinny) I have now bought testers for my Mum and BBF as I need them to be in on the secret!! I am 55 and my skin is better now than ever…people think I’ve had some work done….always been a consideration but now, just not yet!! ❤️❤️

Niacinamide Serum

It's a nice serum, it sinks in quickly and feels hydrating without being sticky. My skin recently decided to throw a fit, so it's nice to find something that doesn't seem to irritate it.


This is super hydrating and smoothing. It plumps up my skin, and along with other Kri products is helping to smooth my skin and make me more fresh faced. It absorbs quickly and easily too.

Beautiful soothing product

Love this beautiful, soothing and smoothing product. I have been using it daily since I discovered it around 3 years ago. Lovely results under the rose-hip oil.

Beautiful hydrating glow serum

I adore this product... in fact I love everything I have tried from this brand. I use this in the evening alongside a retinol and it’s completely rescued my skin. It’s also had a brilliant effect on my décolleté which now being in my 40’s and a previous sun lover was looking a bit tired
