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

Beyond expectations :)

This serum, is lightweight, quick absorbing and made a positive, visible difference within days (and is still continuing to do so about a month later). I have received lovely compliments about my skin and it is feeling calmer, smoother and more even in tone. I definitely feel like I have found my perfect serum - thank you lovely Kri :)

Erythematotelangiectatic rosacea and a 👍 for Illume

So, I have very sensitive skin due to Lupus and Erythematotelangiectatic Rosacea (the flushing at the drop of a hat and prominent facial veins version). Finally, after 57 years, I have found skincare that works. I’ve waited until I’ve used up the Illume Serum, Purify Gentle Cleanser and Timeless Moisturiser before leaving a review. No adverse reactions and calmer, less red skin. Found the skincare a lovely base for makeup as well. Everyone’s skin is different so this may not work for you but I am delighted!

Amazing in cleansing pores

Great serum amazing at cleansing pores and not drying at all. Gives you smooth radiant skin

Game changer !

I'm using Illume after hydrate and I have found it has made a massive difference to my skin. Its smoother, brighter and it really is noticeable. It will be a fixture in my regime from now on.
