This serum feels amazing on

"This serum feels amazing on my skin—lightweight, hydrating, and never sticky. I love the cooling sensation when I first apply it, and the little “snowflake” specks dissolve into extra moisture. My skin feels soft, plump, and dewy, and it layers beautifully with the rest of my skincare. A great pick for that glass-skin glow!"

I’ve been loving this Hyaltoin

"I’ve been loving this Hyaltoin Flooding Serum! It’s a total game changer for my dry skin. My face instantly drinks it up without feeling sticky, and also delivers such a cooling feel and sensation. I also love that it’s unscented! My skin has been super dry lately, and this serum’s 11 hyaluronic acids plus glacier water gave me a plump and dewy glow. I also noticed my skin feels less tight and irritated too. A little goes a long way, so the 1oz bottle actually lasts a while. I’ve used it morning and night, and it works just as well solo or under my moisturizer and makeup. Honestly, it’s a great value for how effective it is. Anyone struggling with dry or dry skin would absolutely love this!"

Brittany (5/5)

This serum feels light yet

"This serum feels light yet very hydrating and absorbs quickly without leaving any stickiness. My skin looks refreshed and plump after using it, and the hydration lasts throughout the day. I noticed my skin barrier feels stronger and less sensitive, especially during dry weather. It gives a nice healthy glow and works well under makeup too. Love how easy this gets absorbed by my skin."

Reviewer (5/5)

I’ve been using the EQQUALBERRY

"I’ve been using the EQQUALBERRY Hyaltoin Smoothie Serum daily, and it feels very hydrating on my skin. The texture is smooth and absorbs quickly without leaving a sticky residue. I love that it has multiple hyaluronic acids and ceramides—it makes my skin feel soft, plump, and protected. My face looks fresher and more radiant, though I noticed it works best when layered under a moisturizer for maximum hydration."

I’ve been using this serum

"I’ve been using this serum for a couple weeks now, mostly in the morning after washing my face. The texture is thin and spreads easily without leaving any sticky feeling. It sinks in fast and doesn’t clash with anything else I layer on top. What I noticed most is how soft and cooler my skin feels after using it, especially around the cheeks and forehead. It doesn’t feel greasy, and I haven’t had any breakouts or irritation from it. The bottle’s small but seems to last longer than I expected. One dropper full is enough to cover my face and neck. There’s a faint scent, but it fades quickly. Overall, it’s cooling and gives a good amount of moisture back to my skin, easy to use, and keeps my skin from drying out."

My sensitive skin was very

"My sensitive skin was very pleased with the performance of this Flooding Smoothie Serum. Not only is it like giving my aging skin a big drink of hydration, but it's equally gorgeous to look at. The dropper is helpful for dispensing just a few drops at a time, and that's really all I need to pat into my skin as part of my evening skincare ritual. It absorbs quickly and completely without making me feel like an oily mess. I found it to be slightly cooling, which is delicious. I am so excited to have found a helpful serum that isn't heavily fragranced. Ingredients like eggplant, berries, and turmeric bring a bounty of skin boosters into the mix. I haven't experienced any irritation or clogging from using this serum repeatedly and I adore it!"

This serum has a slight

"This serum has a slight cooling sensation as it absorbs into my skin. It's unscented, super gentle and hydrating. Not sticky and leaves a glowy sheen."

Dieu (5/5)

If you have dehydrated skin,

"If you have dehydrated skin, this serum is an excellent choice. My skin tends to be oily yet dehydrated, which makes finding the right balance tricky, but this has been working beautifully for me. It contains 11 different types of hyaluronic acid along with five ceramides, which help protect and strengthen the skin barrier. Over the past two weeks, I’ve noticed a real improvement. I used to have a lot of dry skin around the perimeter of my face that would come off when dermaplaning, but now I hardly see any. The serum feels cooling on application, which is especially nice on warmer days, and it absorbs well without leaving behind stickiness. It’s also a very aesthetically pleasing serum, the bottle itself looks beautiful on my shelf, which is a nice little bonus. Based on the results I’ve already seen, I’m confident that with continued use I’ll see even further improvements in my skin’s hydration and overall texture. Highly recommended for anyone with dehydrated or combination skin."

Kristen (5/5)

This is an amazing serum!

"This is an amazing serum! I'm writing this review after using the entire bottle and I must say that I loved it! It's lightweight, but makes my skin super soft at the same time. It doesn't really have a scent. It feels cooling on the skin and gives a pretty glow. I used it once a day in the morning followed by moisturizer. Definitely recommend it!"

Mike (5/5)

I've been hearing a lot

"I've been hearing a lot about skin flooding and when I saw this, I wanted to give it a try. The following is the pros and cons list which was constructed from my experience with the product. Pros: 1) It's made in Korea. As you may know, Korean skincare is where it's at and I wanted an authentic Korean made skincare. 2) Definitely hydrates your skin all day long. 3) Gives my skin that dewy look most of the day. 4) It goes on smoothly and doesn't leave any sticky residue 5) It absorbs very well. 6) It's very competitively priced. 7) This bottle will last you a long time. Cons: 1) I wish it came in different sizes. I would have love to get a larger one. Overall, I would highly recommend this product to people of any age."
