Early verdict · Few reviews so far

What the gurus are saying

B5 panthenol is the real standout, delivering soothing benefits when paired with multiple hyaluronic acids, fermented ingredients, and no fragrance for sensitive skin, according to reviewers. The texture runs thicker than typical toners, so those who make DIY sheet masks may want to reach for something more liquid. The generous bottle size offers excellent value.

"It looks great for my sensitive skin, no fragrance, all those different forms of hyaluronic acid, lactobacillus ferment, peptides. It does have niacinamide, and I know some people can't use that ingredient, but it works for a lot of people. Now, I will say the texture of this is not as watery as I thought it would be, so it's surprisingly a little harder to make DIY sheet masks since it's more viscous. But this really is a huge bottle, fantastic."

"COSRX comes up with their PDRN B5 Vital Soothing Toner for 18 bucks. [...] This one looks interesting. It's got [Centella] PDRN, salmon PDRN, green caviar PDRN. I don't even know what green caviar is. Is that a plant or is that the egg from the fish? I don't know. Then it's got rice PDRN and Lactobacillus PDRN. It looks intriguing. I'll definitely pick that one up if it's on sale."

"The texture is extremely watery [...] and absorbs pretty much instantly giving that fresh glossy look whilst the ingredients in here work to give you that glossy dewy look longterm as well. When you first splash this on the skin, it's quenching. I love that word for toners, but especially in the colder months now, my skin is parched, [...] so the first time I put one layer of this on, it's like an instant quench. And then you can layer this up."

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.

Peptides

Peptides are short protein fragments meant to signal repair. The evidence for them is thinner than for retinoids or vitamin C, and it varies a lot by the specific peptide, so the category is more promising than proven.
