"Not only does this have resveratrol, but it's packed with other antioxidants as well. It has green and white tea extracts. It has superoxide dismutase and it has carnosine, which is a peptide that has antioxidant effects. Plus, I sort of see this as a two-in-one product because it's a hydrating serum and an antioxidant. So, for those looking to streamline their routine or just get more bang for their buck with a product, I love it. And something like this can be used morning or night."

"The next product I'm so excited to include in this collection is by Allies of Skin. It's their Beta Glucan and Resveratrol Advanced Hydrating Serum. [...] I think they're very smart in their formulations and they include a lot of new skin technology and the way they combine ingredients so that you have products that are tackling multiple skin issues at once, I think is very smart, very thoughtful. I think it warrants the higher price tag that these products tend to have."

"This is a double whammy product. It's both a potent antioxidant serum. I mean, we're talking it has 11 antioxidants and it's a serious hydration serum. So, you get one product that does both. In fact, this is the best hydrating serum I have ever tried. And if y'all know me, you know I'm all about hydration."

The Obsession is Real (New Beauty Products)!

"This has been living in my morning routine since the first day I got it. It is chalk full of antioxidants. In fact, it has 11. And for that exact reason, vitamin C is not in my morning routine anymore. It has taken over its spot. But guys, this is all about texture. It is soft. It is bouncy. It is yummy. That is because it's also a mega hydrator. So, for me, I sort of see this as two serums in one. So, I am getting double bang for my buck and it is such a joy to use."

"This is the motherload of all hydrating serums. Honestly, I didn't want to like this product, but I lost the battle. This is bouncy skin in a bottle. And it's also an antioxidant serum. In fact, it has 11 antioxidants in here. So, I was able to replace two serums in my routine with this. One was the vitamin C and the other was a hydrating serum. So, it's a double whammy. I haven't repurchased this yet, but I know that I will."

"One serum that I am obsessed with lately is from Allies of Skin. This beta glucan and resveratrol serum. It's a pretty creamy serum, but I love it. I actually sometimes will even use it in place of my moisturizer in the morning. Even though the texture is a creamy, milky serum, it is a little bit more dense compared to a watery serum. But there's just something about this formulation that is so hydrating. I love the way it feels on my skin."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Vitamin C

Topical vitamin C is an antioxidant with reasonable evidence for dullness and uneven tone. It breaks down in light and air, so how a product is formulated and packaged matters as much as the percentage on the front.

Ceramides

Ceramides are part of the skin's own barrier, and moisturisers built around them have evidence for holding water in and settling the tightness and flaking that come with a damaged barrier.

Humectants and emollients

Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.
