For improved luminosity and brighter, healthier skin.

Lightweight, comfortable and fragrance-free, with 5% niacinamide (Vitamin B3), this serum prevents moisture loss, protects and strengthens the skinʼs barrier, improves texture and balances the skin’s oils.

Suitable for all skin types. Highly beneficial for combination and oily skin.

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

The skincare benefits of niacinamide

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.

We've combined two molecular weights that penetrate below the surface of the skin and form a layer on top. This combination results in immediate and longer-lasting intensive hydration.

The Lowdown on Hyaluronic Acid

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.

Aqua (distilled water)

Niacinamide (vitamin B3)

Glycerin (organic, from rapeseed oil)

Gluconolactone (skin conditioner)

Sodium hyaluronate (skin hydrator)

Sodium benzoate (preservative)

Lactic acid (non-dairy ph adjuster)

Calcium gluconate (skin conditioner)

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.

This stuff legit works

I’m 44 years old and I was noticing more wrinkles around my eyes and mouth than I would like. I ordered this product and my wrinkles are definitely less pronounced after 1 month of use. I don’t look 24 years old, but my skin does look smoother and more healthy. I highly recommend this serum!


Love this serum, lovely and light weight, no sticky residue, hydrating and absorbs very quickly. Tried the mini and just purchased the full size. Definitely recommend.


This serum absorbs into the skin very quickly and once absorbed doesn’t leave a sticky residue. I use this as the first step after cleansing in the mornings.

Great serum

The thing is that dermatologists have said, the sweet spot for the niacinamide to be effective is between 3-5% so I was pleased to find 5% niacinamide serum here in Kri Skincare (most companies try to put 10% in their products). The serum is lightweight and absorbs quickly. I'm using the Vitamin C + Bakuchiol serum after Illume and my skin looks great!

Unsure but ….

Wasn’t sure what I was getting into, so purchased the mini. A couple of weeks in and I’m converted, will be purchasing a full-size soon

Great product

I like the transparency and combination of ingredients used in this formula. I have really been taking care of my skin and ingredients matter and routine. I really like what it is doing for my skin. The bottle looks so elegant as well.
