Roseau is a true rose hydrosol — steam-distilled from Damask rose petals harvested in Beja, Tunisia, at the same family-run distillery that's prepared our flower waters for over a decade.
Unlike diluted "rose water" sprays cut with alcohol and fragrance, Roseau is the actual condensate captured during distillation, carrying the plant's water-soluble compounds, including phenylethyl alcohol and quercetin glycosides, studied for their role in supporting skin's natural firmness and calming the look of redness and sensitivity.
It also resets skin's pH to 4.5–5.5 after tap water (pH 7–8) strips the acid mantle post-cleanse, priming skin to better absorb everything that follows in your ritual.
