The Science of Feel ⚗️💧

Cucumber Ferment delivers a uniquely fresh, cooling, soothing feel because:

• Fermentation breaks complex cucumber compounds into smaller, bioavailable molecules
• Skin absorbs the fermented actives faster and deeper
• Electrolytes & botanical sugars deliver a hydration surge
• Fermentation reduces irritation potential → gentler for sensitive skin

Molecule Spotlight 🔬

• Lactobacillus Fermentation Metabolites → microbiome balance
• Cucumber polyphenols → antioxidant calm
• Peptides → comfort & smoothness
• Botanical sugars → dewy hydration

Tech Behind the Ingredient 🧪

Fermentation uses Lactobacillus to break cucumber extract into:

• Smaller, more absorbable molecules
• More potent antioxidants
• Skin-soothing peptides
• Hydrating polysaccharides

Glossary of Scientific Terms 📘

• Bioavailability: How well the skin can use an ingredient
• Microbiome: Skin’s natural community of beneficial microbes
• Fermentation metabolites: Molecules created by probiotic bacteria
• Polysaccharides: Hydrating sugar chains that bind water
