System Verdict
Well-formulated multi-acid ferment toner with genuinely good barrier support, but undercut by peppermint oil irritation and likely low acid strength. Efficacy is solid because you get a high proportion of ferments plus a full AHA/BHA/PHA/LHA blend in a mildly acidic base, but the acids are all mid-to-late in the INCI (sub‑1% territory each), so exfoliation will be gentle and slow rather than a strong resurfacing effect; safety is dragged down by the sensitizing Mentha Piperita oil in what is otherwise a very skin-friendly, humectant-rich formula.
