IUNIK Beta-Glucan Power Deep Moisture Vegan Serum Intense Hydration Mushroom Yeast Extracts Naturally-derived - Dry Mature Sagging Sensitive Skin Cell Regenerating Lifting Korean Skincare

I’m so glad I learned about beta glucan, because it’s soothing for retinol users, a little goes a long way, absorbing and lightweight! A little goes sooooooooo far, too! Can be a little tacky but after an hour or so it reduces.

I absolutely love this serum! My esthetician told me if I purchase only one product, go with beta glucane. I’ve been using it day and night for about a month, and my skin looks fantastic! Die hard fan! It feels thick and sticky but absorbs quickly and leaves no stickiness on my face at all.

Extremely moisturizing serum. Application is smooth while the actual texture is slightly thick and sticky. No scent and absorbs quickly.. my skin practically drank it up. The only downside for me personally would be the smallest white bumps it leaves on my face (barely noticeable). It's probably my skin reacting to an ingredient in the product but I know this can be another person's holy grail !!!

Love this serum. It is very hydrating for my 53 year old skin. It’s a must in my skin routine.I use this in addition to a couple of other hydrating serums to protect my skin barrier after using actives - especially retin-A.

Has made a big difference in keeping my skin hydrated. Tried a million different moisturizers ranging from thin to thick consistency but all I needed was this toner as an added step. Sinks right into the skin and leaves it feeling hydrated.

Very moisturizing serum - even more so than hyaluronic acid. It isn’t sticky and works well with other serums. I’ve repurchased several times and will again!

I got this to target my dehydration lines as I just turned 21 and it looks like I have wrinkles on my forehead so I got this stuff to help and it didn’t really do anything to help them BUT my skin does feel good tho! I would put it on my lips too and it made them so smooth! While I did make my skin feel awesome, I did not do what I thought it would do. :)

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 onhow you use it, it seems to last a long time.
