A lightweight daily serum designed to hydrate, smooth and brighten the appearance of skin, while supporting the skin barrier and helping to improve the visible signs of ageing.

Niacinamide is combined with hyaluronic acid and glycerin to leave skin feeling hydrated, comfortable and supple, with a smoother, more even-looking appearance.

Suitable for all skin types, including sensitive and mature skin.

5% Niacinamide · Hyaluronic Acid · Fragrance-free

As skin ages, it can become drier, less resilient and more uneven in tone and texture. Illume is designed to address several of these visible changes in one simple step.

Niacinamide helps support the skin barrier and improve the appearance of uneven tone, texture and redness.

Hyaluronic acid and glycerin provide hydration, helping skin feel plumper, softer and more comfortable.

Together, they create a lightweight serum that helps skin look smoother, brighter and more supple, while supporting the skin's natural barrier.

With regular use, Illume is designed to become the kind of daily serum you don't have to think twice about - easy to layer, comfortable on the skin and suited to long-term use.

Niacinamide

Niacinamide helps support the skin barrier and can improve the appearance of uneven tone, texture and redness.

At 5%, Illume uses a well-established concentration that provides meaningful skincare benefits without making the formula unnecessarily complicated.

Hyaluronic acid

Hyaluronic acid is a humectant that helps attract and retain water in the skin, leaving it feeling hydrated and supple.

Illume uses two molecular weights of hyaluronic acid to provide hydration at different levels within the skin.

Glycerin

A simple, effective humectant that helps draw moisture into the skin and supports Illume's comfortable, hydrating feel.

Illume has a thin, lightweight consistency that absorbs easily and layers comfortably with the rest of your routine.

It's particularly well suited to combination and oily skin, but can be used by all skin types whenever skin needs additional hydration and support.

Illume Niacinamide Serum

How to use it.

Apply 2–3 drops to cleansed skin on the face and neck.

Gently press into the skin and allow to absorb before applying moisturiser.

Illume can be used morning and evening. If using it in the morning, follow with sunscreen.

It layers easily with other skincare and works particularly well alongside a simple routine of cleanser, serum, moisturiser and sunscreen.

Less, but better.

We believe skincare should be purposeful.

Illume brings together three straightforward ingredients with a clear role: niacinamide to support the skin barrier, hyaluronic acid and glycerin to hydrate.

Nothing complicated. Just a considered formula designed to make an effective daily serum easy to use.

Less, but better.

Niacinamide is a versatile form of Vitamin B3 used in skincare for its ability to support the skin barrier and improve the appearance of uneven pigmentation, texture, redness and visible signs of ageing.

Why use 5% niacinamide?

5% is a well-studied concentration. Clinical research has demonstrated improvements in the appearance of fine lines, wrinkles, pigmentation, texture and redness with topical 5% niacinamide.

Niacinamide is generally easy to incorporate into a broader skincare routine and can be used alongside many other common skincare ingredients.

If your routine contains several active products, introduce them gradually rather than adding everything at once.

It can be particularly useful for combination and oily skin. Niacinamide has been investigated for its effects on sebum and is widely used in formulations designed for these skin types.

Illume's lightweight, water-based texture also makes it easy to use without adding a heavy layer to the skin.

Illume is particularly suited to anyone looking for:

✓ Daily hydration without a heavy texture

✓ Support for a healthy skin barrier

✓ Brighter, more even-looking skin

✓ Improved-looking skin texture

✓ Support for combination or oily skin

✓ A simple way to introduce niacinamide into a routine

✓ A fragrance-free, lightweight serum

It is suitable for all skin types, including dry, combination and oily skin.

Illume is designed as a daily serum and can be used morning and evening.

Yes, niacinamide and Vitamin C can be used together.

You may have come across blogs suggesting that niacinamide and Vitamin C should not be combined because of concerns about benzene formation. This is a common skincare misconception based on chemistry associated with certain beverage formulations, not the way our products are formulated.

Our Vitamin C + Bakuchiol Serum is oil-based and water-free, using 20% THDA (Tetrahexyldecyl Ascorbate), an oil-soluble form of Vitamin C. It is therefore not dependent on an aqueous pH environment in the way traditional water-based Vitamin C formulations are.

There is no reason to avoid using niacinamide and our Vitamin C + Bakuchiol Serum together.

As always, if you're introducing several new products at once, introduce them gradually so you can see how your skin responds.

Illume is designed to address several common concerns associated with ageing skin, including dryness, uneven tone, dullness, fine lines and changes in texture.

Niacinamide supports the skin barrier, while hyaluronic acid and glycerin provide hydration to help skin feel softer and look smoother and more supple.

More info

A simple formula with a lot of purpose. We don't think every serum needs a long ingredient list. Illume brings together three ingredients with clear roles:

✓ 5% Niacinamide
Supports the skin barrier and improves the appearance of texture, pigmentation, redness and fine lines.

✓ Glycerin
A naturally derived humectant that helps attract and retain moisture.

✓ Sodium Hyaluronate
A form of hyaluronic acid that helps hydrate the skin.

The remaining ingredients are there to create a stable, well-preserved formula.

Nothing unnecessary.

Great products loyal customer for years

I use both the moisturisers and both the serums (Hydrate and Ilume) as my skin needs more attention summer vs winter. I don't know what I would do if you stopped stocking these as they are a life saver. I do miss the gorgeous Rosehip as that in the winter was pure magic!
I Highly highly recommend Kri - beautifully packaged clean products and a great price point too💚

Love this

Really like this serum, Im 49 and starting to get patches of uneven red areas here and there. The serum is clear, odourless and non- sticky and soaks right in. My skin looks even and the patchiness has disappeared. I have oily skin, prone to congestion if not careful and my skin also goes berserk if it doesn't like something. Ive had no reaction at all to this and have had good results, would recommend without doubt. KRI are a crackling little find and so are their products. Friends and family are now customers and are also now big fans.

Excellent product

This is one of my favourite Krī products! My skin laps it up and feels fantastic afterwards. Such a great product to use first after cleansing. A noticeable difference in skin clarity and keeps the wrinkles at bay.

V.L. (Tadcaster, GB)
Fantastic!

I found the Niacinamide and Bakuchiol serum to be quite sticky, whereas this one isn't . It's not too drying and seems to smooth my combination skin with no breakouts. I can feel it moisturizing the dry areas too. Love it!

Just perfect for my sensitive skin

I've been using thisproduct since 1,5 year now I believe, and I really can say it makes a difference in my skin. It is glowing and get less wrinkles. Overall a lovely product, will continue to buy this instead of the nasty ones from average shops.

Best Face investment

I have been using this product for the last one year and my face loves it. My acne faded after one month of use and the reoccurring blemishes permanently disappeared.
This product has smoothen my skin and made it glow.
Love love it

Perfect serum

I have ordered illume niacinamide serum a few weeks ago , another great product of Kri , the serum is my 2nd favourite as i use the hydrate serum as a first step in my skincare routine and then apply a drop of this serum with my moisturiser
( prickly pear moisturiser from Kri)
Kri products are amazing and effective

Good for sensitive skin, but too runny and watery and I didn’t see any difference so far, been using 3 weeks

The works for me by reducing redness and giving my complexion a brightness

D
D.G.

I bought this around 3 weeks ago & it has made an incredible difference to my skin. I am a dark skin black girl and had a lot of pigmentation & blotchy dull skin & this has done wonders for my skin. It has transformed my skin to even glowy and my pigmentation has faded significantly. I don’t have lines so I can’t speak on that but my complexion looks the best it has in years. My skin is quite sensitive & this is the first Niacinamide that I have used that hasn’t irritated me/made me darker & dried out my skin. I’m absolutely delighted with this product. I initially bought the mini size but going to buy the larger bottle & try another couple of their products as impressed with this one.

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!

Classic

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.

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!

J
J.C. (Brooklyn, US)
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.

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.

Lovely serum!

Normally I use Hydrate but tried Illume this time and I'm very much enjoying this super serum on my quite sensitive skin!

Glides on

Glides on beautifully with no pilling. I’m starting to see a visible difference in my skin after using it night and day. My dark spots are reducing and my skin feels more plump in general. I also have no issue wearing this under the kri sunscreen.

S
S.D. (London, GB)
Glides on smoothly!

Glides onto skin easily, sinks in and doesn't feel a sticky feeling. Thank you! Wish it had panthenol included though. Otherwise perfect lil' serum for troubled skin.

Illume Niacinamide Serum for your consideration

I use Illume Niacinamide Serum under Bakuchiol + Vitamin C at night so it is not used in isolation, and it is used after long term elimination of all industrial dyes, perfumes, and microplastics (the first, most important step along with good sunscreen such as made by Kri). I can say that it is very calming to the skin, facilitates an even, smooth tone and makes an excellent base for the serum.

Exactly what I was looking for.

This is the niacinamide I've been looking for, for a long time. Perfect texture, affordable, long lasting, and great for layering. This stuff soaks in quickly, but isn't too thin, nor does it feel cheap. It's perfect if you like to layer your serums. It's already made a difference to my skin. It's my first choice serum. End of.
