"This is an incredible serum and I really love this with devices. It's two times the size of the original and ten dollars off, which is great value. I find it's a little heavy in the warm months so I set it aside in the summer, but come the winter months when your skin feels extra dry, this is so incredible to have."

Best VALUE Skincare (& worst too!)

"This is such an incredible serum, especially in the winter months, and I thought I'd put it aside once it got warmer but no, instead I do the mask system with it, three pumps spread all over [...] and then the silicone mask on top. [...] It's not necessarily the cutest routine, but you want results, you get results."

"The Experiment Super Serum is going to give you more of deep hydration. It can feel a little heavy as we get into summer months, at least for me here in Florida, but that's the same reason I think it is such a good winter serum, and I like what I like, I can't help it."

"This super saturated serum from Experiment is such a heavy duty serum, perfect for the cold months, and incredible under a sheet mask. It's a little heavy because it's thirty percent glycerin, so I like to apply a lightweight moisturizer on top. It also lasts so long because even though it's only a one fluid ounce bottle, it's super thick."

"For my serum today I'm using this product from Experiment, who is also now at Sephora. This is the super saturated thirty percent glycerin hydrating barrier serum. You want to talk about a vegan snail mucin dupe? This is a fantastic example of that."

"Because it's so concentrated it feels just like using a snail mucin product, but this one is vegan, [...] and because of the texture you need such a tiny amount that it's going to last forever. I've been using it as a booster [...] on top of everything else in my routine and it has just been so nice to have that extra boost of hydration, especially in this [...] cold winter. I'm very happy with that product."

NEW Skincare...but is it really new?

"This is an incredible serum and I really love this with devices. It's two times the size of the original and ten dollars off, which is great value. I find it's a little heavy in the warm months so I set it aside in the summer, but come the winter months when your skin feels extra dry, this is so incredible to have."

"This is one of the bounciest hydrating serums I have ever used. 30% glycerin, folks, 30. Like my skin just drinks this up. It makes everything look juicy and glassy and slightly overachieving. [...] If you need a hydrating serum, this is one to go for."

"A hydrating product I really like is Experiment Super Saturated 30% Glycerin Hydrating Barrier Serum. I just say add in that extra hydration after that exfoliation step, so after the exfoliation step add in the hydrating serum and then add in some kind of occlusive moisturizing product."

"You can buy this one by Experiment, which is a little bit janky and tacky, but this is their 30% glycerin serum. You could put a drop of this, let's say literally a drop of this, just very tacky, into your favorite moisturizer. [...] If you feel like you need to get extra moisture, you can mix it in to really allow your moisturizers to infuse more hydration for your skin."

"It also has two percent niacinamide which is in the sweet spot, as well as bisabolol which is derived from chamomile and is soothing, and allantoin which is softening and promotes wound healing which works with the whole barrier support. I like it, I think it's an interesting product. I just did not love the texture. I thought it was too tacky and too sticky. When I used it, my skin was extremely tacky and sticky for a while after I used it."

"This serum is 30% glycerin and when you get into concentrations of glycerin that high, glycerin takes on this additional ability to act as a skin barrier protectant. When you pump this out of the container it's a bit sticky, it's giving snail mucin vibes if you've ever used a product with snail mucin before, but if you can tolerate and accept that texture, this really does pull a lot of water to the skin and make the skin look so plump and hydrated and juicy."

"There's a product from Experiment that came out that's like 30% [...] glycerin or more, and it's also got polyglutamic acid, bisabolol, niacinamide, allantoin, so it has other ingredients that are beneficial in it. [...] It is a little bit of a tackier serum, but it is a nice serum and has been very popular on social media and has sold out definitely a few times."

"If you need that extra dose of hydration, you need to try the Experiment Super Saturated serum. It's one of their best selling barrier essentials."

What the evidence says.

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

Niacinamide

Niacinamide has evidence behind it for redness, uneven tone and supporting the skin barrier, and it is usually well tolerated even by skin that reacts to most things.

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.

Vitamin E

Vitamin E is an antioxidant, and it is often in a formula to keep the other ingredients stable rather than as the active itself. It pairs well with vitamin C, though on its own the evidence for visible change is limited.
