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!"

Tarafying (5/5)

This cream delivers on its

"This cream delivers on its claim. It has a great, lightweight gel texture that leaves the skin feeling deeply hydrated and refreshed without any stickiness or irritation. As a pure hydrating and soothing cream, it works perfectly especially for the hot weather right now, and is an excellent, budget-friendly choice."

I love this brand, I

"I love this brand, I love a lot about their products, starting from ingredients to how it performs on my mature dry skin. This is a lightweight moisturizer that I personally would use probably in the warmer months, because my skin tends to be really dry in winter when I need to apply especially heavy creams. This one is a gel cream, which will be perfect for people who don't like having anything heavy staying on their face for too long. Despite all that, it's still very moisturizing thanks to a lot of hydrating ingredients. I run the ingredients through the Yuka app, and it rated pretty highly. Nothing irritating that will work against sensitive skin. Plus, at the current price of $25, I feel like this is a good deal."

I use a lot of

"I use a lot of K-beauty skincare and really enjoy trying new things. This cream is working really well for me. I'm primarily using this on my abdomen to moisturize my stretch marks, which is probably not the intended use but it's working great. I've been happy with both items I've tried from this brand, and I'm somewhat particular so that's pretty impressive. This moistures well. It's a little heavy, but does absorb completely. It does not leave my skin feeling sticky. The price is reasonable and the size is generous. While I don't think this will magically make my stretch marks dissappear, it does seem to give my skin a beautiful healthy glow. Overall, this was a winner for me and gets five stars."

This EQQUALBERRY HYALTOIN Flooding Cream

"This EQQUALBERRY HYALTOIN Flooding Cream is unbelievably hydrating and soothing. I love using this so much! I have paid close attention to what I put on my face after my skin barrier was compromised, and this was compatible with my skin and caused zero issues such as redness, dryness, itchiness, or irritation. This flooding cream does just as it name implies- it floods your skin with hydration via 11 layers of hyaluronic acid and ectoin. Not only does this flood your skin with hydration, it also locks the hydration in, so what you absorb, you keep...which is why my skin still feels soft and looks hydrated and glowy at the end of the day. The longevity of this flooding cream is impressive! I'd definitely recommend this as a great value for your money."

Customer R. (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)

This flooding cream is fantastic

"This flooding cream is fantastic quality — it deeply moisturizes my skin, cools the temperature of my skin down, soothes irritation and redness, heals and repairs, and restores glow and vitality. It also plumps my skin, helps with dull areas, and restores elasticity and firmness. The texture is more gel than cream and it goes on SO smoothly and absorbs seamlessly into my skin without leaving residue. One of my fave ways to apply this when my skin is ultra dry and dehydrated is to do two thin layers of this cream, then a thicker occlusive cream on top to “seal” everything in and help it last all night — I wake up in the morning with fresh, glowing, hydrated, happy skin every time. This cream can also be used under makeup (the cooling effect is fantastic for makeup) or face masks (for hydration, repair, and cooling, plus if the mask doesn’t stick on well this will help it adhere better). The ingredients are high quality and I love the combo of HA, ectoin, and glacier water. I don’t think this cream has a fragrance (if it does I can’t smell it and it doesn’t irritate my skin). It’s definitely worth the price and is one of my favorite spring/summer moisturizers. I highly recommend."
