Gel texture is plumping and hydrating
Electrolyte mix backed by research

What they flagged

Nothing. None of the experts who reviewed it raised a problem.

What the gurus are saying

The 11% electrolyte mix earns praise for soothing inflammation and irritation, even without traditional calming ingredients like centella or mugwort. Reviewers were struck by how well it settled cranky sensitive skin and balanced combo skin through its gel texture alone. While electrolytes might sound gimmicky, they have solid research backing their hydration benefits, and this serum proves they work in practice.

"What delighted me about this serum is that it's so good at calming stressed out skin. My skin is sensitive, and so it does seem like little things can really throw off the balance. Especially in summer, some of the biggest ones are a lot of heat and sun, definitely sweat can irritate my skin and just kind of throw off the happy balance of my skin. And this product is so good at just sort of calming it down, kind of getting it back into a happy state from being sort of cranky."

All 4 takes from Kelly Driscoll

You're Buying The Wrong "Soothing" Serum (Here's How to Actually Choose)

"I started using this serum this summer and was impressed immediately; [...] I could not believe how soothing this felt on contact. [...] The electrolyte complex, the magnesium and zinc, has an anti-inflammatory soothing benefit, and I've used other Cocokind products [...] with the electrolyte mix and they take down redness and inflammation [...] nicely."

"It's hydrating and that's good, but there's also a little edge to it that just seems to give your skin exactly what it's craving. Calms the inflammation, the irritation, the redness, really plumps up your skin, hydrates it. Not too sticky, not too tacky, not too heavy for the summer months. It just hits every single time."

"This isn't a stranger to my channel, I've been using it a lot this summer. [...] What really surprised me about this product is how soothing it actually is. I figured this would just be a nice hydrating serum, [...] but there genuinely is something about the electrolyte mix in this product, they're using an 11% electrolyte mix that really suits my skin and calms down irritation, inflammation, and cranky sensitive skin."

"The new Cocokind Hydrating Electrolyte Rescue Serum is a potential new favorite. It's brand new so I'll follow up with longer term thoughts, but it turns out the serum is incredible. The electrolytes almost sound gimmicky, but they do in fact have research supporting their use for hydration and skin support."

"Cocokind is one that I actually discovered in Utah when I was there because it really helped me. It is loaded with ceramides. It is a rich but not too rich hydrating serum that's going to help restore your skin barrier, and it does not have hyaluronic acid."

What the evidence says.

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

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.
