What the gurus are saying

The fermented kombucha base draws repeated praise for delivering deep hydration that absorbs quickly without stickiness or tacky residue. Reviewers noted it plumps and locks moisture in while staying lightweight, works across all skin types, and offers exceptional value at $16 for 150ml; the bottle lasts months with daily use. Panthenol, beta glucan, and vitamin E round out the ingredient profile.

"I've been using this since 2022, and I bought so many bottles of this with my own money because I deeply enjoyed it. I even named this as some of my favorite hydrating skincare and some of my favorite toners in 2022 and 2023. It's a really fantastic toner, very very hydrating, and I have a dehydration beast in my skin so I need something very, very hydrating, and this dives down deep into the skin to give that replenishing deep hydration. It also has just a little bit of plumping body to it that helps lock the hydration in, while still maintaining a lightness and a wateriness, a quickly absorbed quality, without drying sticky or tacky on the skin. The ingredients are so good, there's fermented tea content, it's kombucha, lots of antioxidant content, polyphenol content, amino acids, and the fermentation supercharges all of it. This summer I only need one layer of it because that's just how good it feels on my skin."

"I've got one percent panthenol which is a good skin soothing and wound healing ingredient, hydrolyzed hydroxyethyl urea which is a urea derivative with strong moisturizing and humectant properties, beta glucan good humectant skin soothing anti-inflammatory, and then finally we've got vitamin E which is a great antioxidant and hydrating ingredient. So a really nice list of ingredients in here. I'm very impressed with it. They did a really nice job with their ingredients. The nice thing about this product is it's friendly for all skin types really, and for acne prone skin just the vitamin E to be concerned about. So it's really nice to see a product because there's not a lot of products that are really friendly for most skin types. In terms of the price, this is a full size 150 milliliters for 16 dollars. That's a bargain it really is. It's a pretty large bottle, a little bit of it goes a long way. If you're not gonna use a cotton pad this bottle will last you a long time. I've been working on this daily for three months or so, really giving a good test there, and it's still got a long ways to go. It's a super nice toner. It's fragrance free, it's cruelty free, it's affordable, it's vegan."

What the evidence says.

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

Urea

Urea both holds water in the skin and gently loosens dead surface cells. At higher strengths it has good evidence for very dry or thickened skin.

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.
