Rated 5 out of 5 by from Honestly, anything by The Ordinary is amazing. As a graduate student with a tonne of debt, I greatly appreciate how accessible this brand makes their products because they are so affordable. I use this as a serum before moisturizer and it gives my moisturizer an extra kick (also allows me to use less moisturizer). Some days I will just wear this and the Buffet instead of any moisturizer. Absorbs quickly and isn’t greasy at all. Has an odd smell (some reviewers have said it is fishy but I think it smells more like garlic or something) but disperses after a couple minutes. After my first purchase, I came back and ordered five. Just order one, you can’t go wrong!

Rated 5 out of 5 by from my thirsty skin has been QUENCHED the skin on my face used to constantly be so dry & tight and i'd have to apply creams over and over, but after using this and the natural moisturizing factors my skin is hydrated and moisturized all day, without the need to apply anything else until before bed. it is very thin as others have said - what i do is have the dropper in one hand and apply it right to my face with my head tilted up, and have my other hand right there ready to spread it around. i do this three times - on my forehead and on both cheeks. there's also little to no smell and it only lasts a couple seconds anyways, so don't let reviews about the "bad smell" deter you from trying this!

Rated 2 out of 5 by from I'm a fan of many of The Ordinary products but this one made me breakout, literally overnight, in whitehead pimples. It took me a few weeks to figure out it was this product. I stopped using it and no more pimples and used it last night again for the first time in a few weeks and I woke up this morning with 2 whitehead pimples and I have not had pimples like this since I was a teenager. I loved the product outside of that so it was disappointing it didn't work for me.

Rated 5 out of 5 by from My skin has never felt so hydrated! Smells a bit like a fishing boat, but the smell fades quickly and I’m used to it. I buy this 2-3 bottles at a time to be sure I’ve always got backup. (Note: I find the ordinary’s hyaluronic acid serum to be too sticky to be comfortable for my skin, and was thrilled when they came out with this option.)

Rated 5 out of 5 by from Great product. Very watery (noticed another reviewer mentioned a spray bottle: not a bad idea!) but absorbs quickly and adds an extra shot of hydration antioxidants soothing agents to your skin without adding extra weight (I use it under a serum and a cream). It would also be nice if the packaging was more UV protectant as a lot of the active ingredients seem to be photosensitive. But I generally keep my products in a cupboard so that's not an issue for me.

Rated 5 out of 5 by from I use this in the morning to hydrate along with a couple The Ordinary products at night and I've been pleasantly surprised. It doesn't smell the best but it's faint and goes away so quickly. Very lightweight, I apply this then sunscreen and makeup. Highly recommend!

Rated 3 out of 5 by from This is my first time using this and it's been about 2 weeks. When I use it on my face under my moisturizer, it absorbs quickly and seems to make the effects of the moisturizer last longer because my face isn't dry and itchy by the end of the day. It had no impact when I used it on its own on my face. I really wish I could get it in a spray bottle to make it easier to apply because it's a bit awkward as it is.

Rated 5 out of 5 by from A great moisturizer for summer since it's very lightweight and quick absorbing, not greasy at all. A little goes a long way. In the drier months I'll add a couple drops squalane on top or mix the two together for some added hydration. I agree with the others, though - smells bad! However the smell just reminds me that there are no added fragrances which is a definite plus for my sensitive skin.
