A lightweight moisture serum designed to replenish dehydrated skin and leave it feeling fresh, comfortable and beautifully hydrated.

Hydrate helps relieve the feeling of dryness and tightness while leaving skin looking smoother, plumper and more refreshed.

Containing organic rose water, Its light, fluid texture absorbs easily and layers effortlessly under moisturiser.

For skin that needs more moisture, without more weight.

✓ Deep, lasting hydration

Hydrate gives skin an immediate boost of moisture while helping it stay hydrated throughout the day.

Ideal when skin feels dry, tight or dehydrated, or simply needs an extra layer of comfort.

✓ Smoother, plumper-looking skin

Well-hydrated skin looks smoother and more supple. Hydrate helps soften the appearance of fine lines associated with dehydration, leaving the complexion looking fresh and rested.

✓ Lightweight and easy to layer

The fluid, fast-absorbing texture sinks easily into the skin without feeling sticky or heavy.

Use it underneath your usual moisturiser, or layer it with other serums as part of your routine.

✓ A simple way to give dry skin more

Hydrate is particularly useful for dehydrated skin, including skin that feels dry or less comfortable as it ages.

It's a simple addition to any routine when your skin needs more hydration.

Hydrate combines a small number of purposeful ingredients chosen to replenish and maintain moisture in the skin.

Organic Bulgarian rosewater gives the serum its refreshing, lightweight base.

Hyaluronic acid and glycerin are humectants that help attract and retain moisture, leaving skin feeling hydrated and supple.

The result is a simple, lightweight serum focused on one thing: giving skin the moisture it needs.

How to use it.

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

Gently pat into the skin and allow to absorb before applying moisturiser or facial oil.

For best results, follow with a moisturiser to help maintain the skin's comfortable, hydrated feel.

Hydrate can be used morning and evening. It's also easy to layer with other Krī products.

Less, but better.

Not every product needs to multitask.

Hydrate doesn't need to do everything. It's designed to do one thing well: give dehydrated skin more moisture and leave it feeling soft, smooth and comfortable.

A lightweight formula, purposeful ingredients and nothing unnecessary.

Hydrate Moisture Serum | Kri Skincare.

Hydrate Moisture Serum is particularly suited to:

✓ Dry or dehydrated skin

✓ Skin that feels tight or uncomfortable

✓ Combination skin that needs additional hydration

✓ Anyone who prefers lightweight, water-based serums

✓ Skin that needs an extra layer of moisture beneath a moisturiser

✓ Anyone looking for a simple hyaluronic acid serum

It is suitable for all skin types.

Both are water-based serums, but they have different purposes.

Hydrate is focused on moisture. Its formula centres on glycerin and sodium hyaluronate.

Illume contains 5% niacinamide and is designed around the broader benefits of niacinamide, including support for the skin barrier and improvements in the appearance of uneven tone, texture and redness.

Choose Hydrate when your priority is hydration. Choose Illume when you want a niacinamide-focused serum.

You can also use both if your skin benefits from additional hydration.

Yes you can. Hydrate is a simple water-based hydration step and can be used alongside our Vitamin C + Bakuchiol Serum.

Apply Hydrate first and follow with the oil-based Vitamin C serum, then moisturiser.

Hydrate contains organic Bulgarian rosewater, which has a naturally occurring rose aroma.

It does not contain added synthetic fragrance or perfume.

If your skin is particularly sensitive to fragrant botanical ingredients, patch test first.

Hydration achieved

I like this product so far . I've been using it for one month now with tretinion and had no problem with dryness after tretinion. I like it so far and I like the smell.

Disappointing

Unlike other Kri products, it is not fabulous. Feels drying and basic as you apply and is a weak hydration. I will not be purchasing again

Thank you for taking the time to leave a review. We appreciate your feedback and we're very sorry to read that this serum no longer meets your expectations, especially as it was a repeat purchase for you.

I tried Illume first, but prefer this one in my morning routine. It's lightweight, yet it feels substantial. I pair this with the endless moisturizer or my sunscreen moisturizer (different brand) every morning and my face seems happy.

Wonderful

I found Kri when I was struggling to source my usual hydrating serum. This is the first product I bought (thank you for trial/travel sizes!) and I haven’t touched the other one since. I do have to use 4 drops, but that covers my whole face, eyes & neck and really does leave my skin feeling hydrated. The bottle still lasts a good while even using 2x a day. My skin is sensitive with rosacea and peri-menopausal, and turning from combi to dryish. This is soothing & doesn’t aggravate at all. I love the simplified ingredients and ethos of the whole brand.

Didn't give my skin much hydration

First of all, I'd like to say that I'm a huge fan of Kri Skincare. I suppose I had quite high expectations of this product as well, but I was a little bit disappointed. I had to use a lot of it each time and yet it didn't give me much hydration at all. My skin felt quite tight after applying it. I love the scent and the clean ingredients though.

I use this under the facial moisturiser to keep my combination skin happy 😁

Smells nice

I do like this serum a lot, but found I had to use a good deal more than it says. At first I was using 1-2 drops and wondering why it didn't seem to be making a difference, but because I got it on sale, I decided to just try putting on as much as I wanted, and my skin immediately looked and felt smooth, glowy and hydrated. I gave 4 stars because of this reason only, because it does go quickly at that rate, but the ingredients and results are top notch.

An amazing product with the nicest rosewater smell

This has it all.. A fantastic hard working serum but seriously an amazing light scent of rose.. It really has it all and I wouldn't be without it

E
E.P.

I have super dry skin so am always so happy to find anything that’s keeps my skin from feeling uncomfortable throughout the day. This serum is brilliant, I have also mixed with a few drops of the bakuchioil serum and the endless moisturiser and my skin is feeling so much smoother and hydrated. Think I’ve found my new holy grail combination for dry skin.

For dewy skin

I alternate between Illume Niacinamide Serum and the Hydrate Moisture Serum as my first step. It gives the perfect hydration to my skin as a base layer. I just add a few extra drops than what is recommended for a good glide. Also - I love the relaxing rose scent.

Perfect for dehydrated oily skin

My skin is sensitive, acne prone and dehydrated, this is serum is perfect for me. Also,unlike most of other hyaluronic acid serum that I tried, it's not sticky at all and little goes a long way! Love it!!!

J

Lovely lightweight serum

I really like the light consistency of this serum as it is well absorbed and does a great job of hydrating my skin. I do find I need to use a few more drops than the recommended 'couple' to cover my face and throat.

Skin saver

My skin care go to. I've been using this for years as a base under facial oils and/or moisturiser. I have combination skin that is oily but prone to dry patches and blemishes. I really think this helps with hydration, sensitivity and redness.

My favourite skincare product ever

I've been using Hydrate for about a year now - sometimes layering, sometimes not, I'm not the most disciplined! - and it has made an unbelievable difference to my skin, which can be highly reactive. It is light, gentle and easily absorbed, with a very subtle scent.

My skin is beautifully clear and soft, and I believe it has also improved the appearance of the fine dryness lines I was starting to develop around my eyes.

Kri's commitment to sustainability and the environment is hugely important to me, and I love the fact that I can order refills, doing away with the need for unnecessary packaging.

A genuinely life-changing product, which I intend using for the rest of my life!

Hydrate Serum

I bought the mini version of the Hydrate serum to try and I'm glad I did. I have sensitive skin that is prone to redness & while I liked the subtle smell of rosewater the serum has, sadly my skin did not. On the plus side it sinks in nicely & makes a nice treat for my hands which don't seem to mind it!
