What the gurus are saying

Beta glucan delivers hydration across multiple skin layers while reinforcing the barrier, and the serum absorbs quickly without feeling heavy, making it easy to layer under moisturizer or sunscreen or wear alone in warmer months. The formula also includes adenosine, which gurus note supports skin cell function and may help with fine lines over time. The dropper design could be smoother, but that does not affect what the serum itself does for hydration and skin texture.

"I think it's just a really great, simple, straightforward type of serum for sensitive skin. It has an incredibly minimal ingredients list focused on the star ingredient, beta glucan, which is an amazing humectant ingredient often derived from mushrooms that's incredibly hydrating, healing, and soothing. The product itself has not changed since 2019, only the packaging and how the ingredients are listed. It's very hydrating, soothing, and anti-inflammatory, with a texture almost like a lighter version of snail mucin, so it's a great vegan alternative for people who don't want to use snail mucin. It's not an immediate relief type of product, it's more of a long term product you use morning and night, and your skin holds onto hydration a lot longer. I still continue to use this product and I do recommend it a lot, particularly for dehydration, irritation associated with dehydrated skin, barrier issues, and any type of sensitivity."

"The iUNIK Beta Glucan Power Moisture Serum is a lightweight yet deeply hydrating serum that helps really boost moisture at different levels of the skin. It's got that beta glucan that we know is really helpful at hydrating the skin but also supporting the skin barrier. It's a good humectant as well and it's pretty lightweight. You can layer it under sunscreen, under your moisturizer, or in the summertime use it alone as almost like your moisturizer. Aside from beta glucan, it's got other wonderful humectants like glycerin and sodium PCA that are good for supporting your skin moisture barrier. And then adenosine, which is really kind of like a cell energizer that helps improve your cellular function, really used for anti-aging, improving fine lines and wrinkles."

"This one is from iUNIK. It's the Beta Glucan Power Moisture Serum. Beta glucan again a very great barrier building ingredient. This dropper didn't do the best job there, but you can see it kind of has that sort of snail mucin feel to it. Absorbs super well into the skin and it's just going to give you that extra hydration that's going to give you that dewy skin."
