Illume Niacinamide Serum


Niacinamide is one of the ultimate skincare workhorses. It strengthens the skin’s barrier and helps protect from urban pollution. It balances oil production, minimises breakouts, and helps to reduce redness.

Hyaluronic Acid

Hyaluronic acid, alongside glycerin, is a brilliant humectant for your skin. It delivers an immediate increase in hydration, leading to a plump, smooth and glowy complexion.

A combination of two molecular weights of hyaluronic acid penetrate below the surface of the skin and form a layer on top. This combination results in immediate and longer-lasting intensive hydration.

*We’re sometimes asked about gluconolactone and whether this product will exfoliate the skin. Gluconolactone is present in our preservative system at a very low percentage. It does not act as an exfoliator at this low level of inclusion in the overall formula.

Apply a couple of drops to cleansed face and neck. Use your fingertips to gently pat serum around the eye contour area. Allow to absorb before continuing with your next steps, which will be antioxidants and a moisturiser.

Nice serum

This is a nice moisturising serum. Effective and gentle

Magic in a bottle

Simple ingredients means you know what is going on your skin. Simple routine helps to keep things in few steps. Skincare shouldn't be a mind field. I have found my skin illume!


This is my second time purchasing this. It’s non irritating, hydrating, and after about 4 months, my acne scars and breakouts have vastly reduced. Minimal ingredients and it does the job.

Best cleanser!!

Best cleanser!! It leaves my skin both clean and moist. I wouldn't be without it.

Light, Hydrating and...

My skin is combination-oily but very dehydrated, though it has recently become sensitive and dry following use of some active ingredients. Illume Niacinamide serum is light, hydrating and does not feel sticky. It absorbs into the skin easily and soaks in quickly. It has been about 3 weeks since I started using the serum. I apply a rich moisturiser and a few drops of oil after the serum to achieve more hydration levels and help with skin repair.

Favorite serum

My favorite Kri Skincare serum! The texture is so pleasant and the result is wonderful. I use it morning and evening as my first step and under Vitamin C Serum and Timeless Moisturiser (am) / Endless Moisturiser (pm). It gives a beautiful glow and a nice boost in hydration. Highly recommend it!

Gentle and effective

Love this serum. It works gently, and at 5% niacinamide concentration, it's safe for skin. I also love that it contains HA. This alone wasn't hydrating enough for me as I have very dry skin, but following up with oils and/or a moisturizer always suffices. I've only been using for about 6 weeks, but will be buying another bottle.

Top must have product

I've been using this for years and absolutely wouldn't be without Illume serum as part of my daily Skincare regime

Second Purchase

Second time purchasing this serum, I use it daily and very much like it :D

Very good experience so far

Only a couple of weeks into use but it is very quick and easy to apply and feels good on my sensitive skin. I was focused on finding more sustainable and effective skincare and I am really glad this company was recommended to me.
