IUNIK Beta Glucan Power Moisture Serum (50 ml)

Very hydrating and it did not irritate my very sensitive skin.

Heard about this online and worth the hype. Better than hyaluronic acid and really good for dehydration. Get this especially if you suffer from dryness due to retinols. Will be re-buying

I have used this product for a while now.I came across the Beta Glucan serum benefits as I have a sensitive skin and the hyaluronic acid serum used was making my face a bit reddish.I started to use this brand and I have to say it has helped my skin to get much better.But it has been a slow process though, took a while but it might be me then not the product. Overall is a really good product, I would recommend for sensitive skin.

Great moisture serum Easy to use, pleasant aroma great price point Good sort of instructions on the box and on the bottle so it’s easy to use Her skin feels good and makes her feel good

Hydrating serum with no fragrance. It’s thick so the pipette doesn’t work very well. But can scoop out fine.

Fourth bottle, love it! Hydrates without clogging the pores

I bought this as a recommendation from TikTok and it seems to irritate my skin. So I wasn’t able to use it to see if it improves my skin. That’s just my experience and everyone’s skin is different so I’m not saying don’t buy it, just that it didn’t suit my skin

I don’t usually write reviews, but I need to share as this serum saved my skin. It had never felt more moisturised and plump. I had small so many closed comedones for 6 months because of a compromised dry skin barrier and my skin overcompensating with oil production, but after 3 nights using this they completely disappeared back into my skin. I am so amazed at this product and it is now a staple in my routine.

Recensione di mia moglie: Lo avevo usato diversi anni fa quando ancora aveva l'etichetta color marrone ed era difficilmente reperibile in Italia se non facendolo spedire dalla Corea. Mi ero trovata molto bene ma, essendo acquistabile solo su siti esteri con spedizioni lunghe, avevo poi lasciato perdere. Recentemente ho visto che anche Amazon lo vende e ho deciso di ricomprarlo. È davvero un prodotto molto valido, la mia pelle (42 anni, ultrasensibile, mista con zone secche soprattutto sul contorno occhi e soggetta agli effetti collaterali di un farmaco non leggerissimo) è rinata fin dalle primissime applicazioni. Ha una consistenza tipo gel che si assorbe subito. Sotto l'abituale crema idratante è un portento. Utilizzabile sia mattina che sera.

Can’t go without this as my first serum in my AM or PM routine. It’s a hylauronic acid but better that gives you the best hydration before putting on any other serums or creams. Does not interfere or pill with my other skincare. Works beautifully under makeup and is fungal acne safe which is always one of my biggest concerns when purchasing products!

So hydrating without irritating my skin

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 doesn’t leave a residue and it plays well with other skin care products as well as makeup/sunscreen. As someone else mentioned it’s not as “life changing” 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 “natural” 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 “dewy”. I mixed a small amount in a little “tester jar” 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 doesn’t 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, it’s 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 I’m really happy I tried it. So the purchase based just on that was worth it to me. Depending on how you use it, it seems to last a long time. Updated Comment 3/2026: I’ve been using this serum as part of daily my “skin flooding” routine. It’s kept my 59 year old skin looking plush and healthy. My fine lines aren’t as noticeable and the routine is easy, affordable, and all available on Amazon. I cleanse (I do a double cleanse when I’m wearing the Australian Gold BB Cream/Sunscreen), perhaps use a toner, spray my face with Avene Eue Thermal Mineral Water (or leave wet), apply the Beta Glucan Serum generously (2-3 droppers full), let it set for a minute or so, apply either Vanicream or CeraVe Intensive Moisturizer. If I’m going to be wearing makeup I will then apply my primer a minute or two after letting the moisturizer set (which will further reduce moisture loss), then apply my sunscreen/BB cream. I’ve also worn my P. Calm Sunscreen (which is amazing, BTW), over the serum after it has absorbed a bit on days when I’m not wearing makeup.

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!
