River Cucumber Soap

Cucumber Juice is the cool splash your skin’s been daydreaming about. Lightweight, hydrating, and wonderfully soothing for sun-warmed or easily irritated skin. Packed with vitamins C and E plus naturally clarifying plant compounds, it helps refresh tired skin, tighten pores, and leave you feeling just a little closer to becoming a freshwater mermaid.

Spirulina is the superfood smoothie of the skincare world. Packed with antioxidants that help soothe skin and calm irritation. The chlorophyll in spirulina helps draw out impurities, clear pores, and oxygenate the skin, all while giving the bar its rich river-green hue.

French Green Sea Clay’s color is primarily from ancient algae, kelp, and other chlorophyll rich matter trapped in the clay. Deeply cleansing and skin-balancing lather delivers a mineral-rich dose of magnesium, calcium, silica, and potassium to help revitalize tired skin. It gently draws out impurities and excess oil, softly polishes away dullness, and leaves your skin feeling fresh, smooth, and renewed.

Extra Virgin Olive Oil is a love letter to your skin. Deeply moisturizing, rich in antioxidants, and extra gentle. It creates a creamy lather that cleanses without stripping, basically giving your skin a soft, dewy high-five.

River Cucumber Bar — A Freshwater Mermaid’s Talisman

The River Cucumber bar divines in waterside summer living. Poured full of freshly juiced cucumbers and sprinkled with cucumber peel confetti, nutrient-rich spirulina and Green French clay, bubbling into a cool, clean, deeply hydrating lather.

Scented with cool cucumber waters, muddled watermint, and sun-crackled lime peel, this limited edition bar is a whimsical discovery turning an ordinary shower into a shady swimming-hole escape, somewhere between a skin-cooling river dip and a quiet freshwater mermaid encounter beneath the lily pads.

The top half of the bar, a deep river green, rich with freshwater spirulina algae and French Green clay. Both ingredients packed with minerals, chlorophyll, and skin-loving nutrients that help clarify, nourish, and rebalance. Beneath it, the lighter half is extra virgin olive oil, freckled with cucumber peel powder. The layers remind us of the delicate dance between humans and nature: the water that cares for us also needs caring for in return. We can all be river guardians.
