Lightweight and hydrating step in skincare routine
A very lightweight and hydrating serum that absorbs well into skin. Doesnât leave any filmy residue like I had with snail mucin. This serum also had a calming effect when I layered it before tretinoin. No problems using with sunscreen or makeup. This has drastically improved the look and feel of my skin.

Game changer – great on its own or mixed into cosmetics
This is a great hydrating serum to add to your skin care routine. It is quite thick and a little goes a long way. It doesnât leave a residue and it plays well with other skin care products as well as makeup/sunscreen.As someone else mentioned itâs not as âlife changingâ as some of the claims, however it can also be used to add moisture to other products.I have a favorite sunscreen (Australian Gold light) which happens to be matte when it drys. At 57 with some fine lines all it did was highlight those no matter what primer or moisturizer I used underneath.The color (it doubles as a BB cream) is perfect for me because it has slightly pink undertones. I wanted to move away from my foundation routine and have a more ânaturalâ look. Finding a hydrating replacement was impossible.Knowing beta glucan is added to many skin care products to enhance hydration, I decided to experiment with mixing a ratio of 40-50% beta glucan to my sunscreen to make it more âdewyâ.I mixed a small amount in a little âtester jarâ I had. After thoroughly mixing, it set overnight to ensure the ingredients meshed together. (I first tried this in my hand and it took awhile for everything to come together so it was homogenous).The next day I applied it to my skin and had exactly what I wanted. A silky light to medium coverage sunscreen that left my skin looking slightly dewy, but not greasy.Once it set (was no longer shiny), I applied a bit of blush and that was it. It set up leaving me looking natural – not overly dewy. It also had enough coverage to hide unevenness in my skin tone. It also doesnât highlight my fine lines as much- only slightly under my eyes (which at my age comes with the territory).I also use this as part of my AM and PM skincare. Layering it with HA and my vitamin C serum.I will also use a bit before using my CosRx masks to add a bit more hydration. I usually spray my face with Eue Thermal mineral water before applying the beta glucan (or any HA product), then apply the mask.Overall, itâs a great option for anyone allergic to HA or wanting to boost their routine.Will it perform miracles? No. But it is a great booster.Using it in some of my cosmetics took some trial and error, but Iâm really happy I tried it. So the purchase based just on that was worth it to me. Depending onhow you use it, it seems to last a long time.

Great for compromised skin barrier
I use Tretinoin on my dry, sensitive skin mature skin so I’m always looking for products that support my skin barrier. The texture is great, feels thick but dries down quickly after a few pats from my hand. I use it after my milky toners and before my moisturizer in my skin care routine and it has made a difference in keeping my skin hydrated.

A regular part of my sensitive skincare routine now
Love this serum for my sensitive skin. Very calming and hydrating under moisturizer, particularly if skin is irritated from another active. Will always keep this as a staple now. Great for using with other moisturizing products to build up a robust skin barrier.

Better than a regular hyaluronic acid!
This is the best hydrating skin care serum that I have ever tried on my face! I use tretinoin and my skin loves this serum. It has a thicker consistency and not watery like some serums but it makes a little go a long way!

Long lasting hydration
Hydrating, calming, moisturizing on the skin without being sticky. It absorbs very fast keeps my skin hydrated for a long time. My skin type is oily but dehydrated and using the wrong serums can ruin my makeup in summer due to my skin over producing oil. This product with a light lotion type spf is all I need to ensure a long lasting, glowing skin for summer!

Wanted to love it…..
I have been practicing skin care for many years and have tried many products. I used to have very oily sensitive skin but over time it has become mature, dry, and sensitive so I adjusted my skin care accordingly as needed.I like the Iunik line and use a few of their products in my rotation. This serum does moisturize the skin quite well but I find that if I use it for to long of a time it causes red flaky patches on my face that are not at all desirable traits from a skin care product. I would put this down to an isolated incident but it did the exact same thing to my bf only worse and with only one use. I wanted to love this serum but because of the side effect on my skin I just don’t. That being said it is a good product but it just may be too much of a concentration for my skin to tolerate in anything but short periods of usage. Everyone’s skin is different and this is just my experience

Super hydrating!
Super hydrating serum! Has a sort of thick sticky consistency out of the bottle but once applied to skin becomes liquid-like and absorbs super fast while leaving skin hydrated. I have sensitive, acne-prone skin but it has not irritated my skin at all.

This was recommended by my facial lady who does a lot of research into skin care. My skin is dry so this serum is perfect for hydration and I’ve noticed a differece in my skin since using it.

I tried this serum for the first time and was surprised how much I liked it. It is perfect to use on dry skin and works together with other products/ingredients without problems. It’s gentle, absorbs fast and is also fragrance free which is a huge plus. This serum is worth every penny; the bottle is generously sized and a little goes a long way! Will for sure reorder.

adoro questo siero, l’ho già ricomprato più volte! viscoso al punto giusto si asciuga facilmente e lascia la sensazione di pelle rimpolpata e compatta oltre che fresca

meilleur que l’acide hyaluronique!!! il est bien plus puissant pour retenir l’hydratation et repulper la peau et la lisser. Perso je le mets après mon sérum rétinol et avant ma crème de nuit, le lendemain la peau est repulpée lissée et surtout ne graisse pas! bonne trouvaille et je recommanderai!le flacon a une grande contenance de 50ml et il ne faut que 3/4 gouttes c’est bluffant!
