The Iunik Beta-Glucan sunscreen makes my skin look so good, I forget it’s also protecting it.

Part of the K-beauty brand’s Beta-Glucan line of skin care products — a multi-beneficial ingredient that can help improve skin barrier function, increase hydration and soothe redness — the water barrier sunscreen is closer to a daily lotion than anything else. Now, if you’re at all familiar with Korean and Japanese sun creams, you’ll know that this is a common characteristic of these superior formulas. But after trying the lot of them, it’s never felt truer than with this innovation from Iunik.

What really sealed the deal for me was how this sunscreen wore throughout the day, curing a pain point that other SPFs, even those of Korean origins, fail to address. After so many hours, many formulas will begin to pill slightly or oddly separate underneath my makeup, specifically on areas like my chin or around my nose that are typically most impacted by my Tretinoin use (or abuse, rather). The Iunik sunscreen remained a steadfast ally in keeping my foundation looking as flawless as the moment I applied it. I even tested it with both a layer of my liquid foundation and my cream and powder products, and its incredible performance was maintained.

Compatible with all skin types and especially gentle for sensitive eyes (I’m a contact lens wearer, and there is no stinging to speak of when wearing this, even if I sweat), this sunscreen is enriched with more than just beta-glucan, which the brand claims “holds up to 20% more moisture than hyaluronic acid.” This ultra-hydrating skin protector also features a powerful peptide blend, which we’ve been previously told by dermatologists is an effective ingredient for promoting collagen production and improving the elasticity of the skin. It also contains a fermented ginseng extract, which is a source of antioxidants for neutralizing environmental stressors that can cause premature aging of the skin.

“Possibly the best sunscreen ever! I was looking for a sunscreen that didn’t feel heavy or greasy, and made my skin look beautiful. This is it,” one 49-year-old Amazon reviewer said. ” My skin looks plump and hydrated and it plays nicely with makeup.”

“Possibly the best sunscreen ever! I don’t usually leave product reviews- but this sunscreen deserves it. I was looking for a sunscreen that didn’t feel heavy or greasy, and made my skin look beautiful. This is it. It feels quite serum-like on the skin but doesn’t make me shiny. My skin looks plump and hydrated (I’m 49) and it plays nicely with makeup. I would buy this girl over and over again.” —Suzabelle

“After trying countless of sunscreens… this one wins. The best sunscreen I EVER used. I spent hundreds of dollars trying to find the perfect sunscreen for years. This one has no cast, no eye sting, no grease, and no fragrance. It gives a natural glow without looking oily (i have combination skin). There’s no residue on my fingers when I touch my face. It feels like I have regular light weight lotion on. This is a permanent staple! BUY THIS.” —Dream

“FINALLY..... my HG sunscreen. Texture is like a thin moisturizer. It’s lightweight and dries down so well. Sometimes with other sunscreens I can feel a tug whenever I move my face like it’s just sitting on top of my skin, or when I sweat it’ll feel like my skin is being trapped under a layer that fights my sweat coming through...... With this sunscreen though, it doesn’t feel like I have anything on. I don’t look like I’m sweating or greasy just from wearing it. No white cast (medium brown). And the pros I’ve listed are an all-day thing too! I’ve recommended this to multiple people. I love it so much. Plus the cost for the amount you get?? Omg. Forever coming back for it.” —Cmac

“Feels like lotion. HOLY GRAIL SUNSCREEN. I am a skin cancer survivor and I am extremely picky about spf. Most sunscreen gives me hives. This didn’t! This is sunscreen that feels like skincare. It’s gorgeous on my skin, it doesn’t feel like any sunscreen I’ve ever tried before. It feels like my regular everyday moisturizer. It is perfect under makeup and, it applied over my makeup beautifully too! This is a holy grail sunscreen!! I even wore it to the beach. I was in and out of the water all day, wearing goggles, playing mermaids, doing the George Washington hair. I reapplied as usual and it layered over my face every time with no problems. My skin felt incredible after that day. No breakouts. It seemed to be somewhat water resistant which is unexpected with this formula. My only issue was that my chin very lightly got burned, but that could have very well been my bad. I was drinking at the beach and probably missed a spot. The rest of my face neck ears etc were fine. I’ve already bought a second bottle and sent some to my sister and mother. This is never going to be out of stock inside my house. This is INCREDIBLE.” —Bee Bee
