How we score →Yay
3 experts · Moderate agreementWhat the gurus are saying
Fermented ingredients and probiotics earn praise for working well across different skin types. The toner is light and gentle, with a subtle fragrance that most people find unnoticeable. Gurus report seeing visible benefits from regular use, though if you're sensitive to fragrance at all, a patch test first makes sense.

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

Salicylic acid dissolves in oil, so it can get into a pore rather than just working on the surface. That is why it has long-standing evidence for blackheads and milder acne.

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.
