Proven Benefits

Replenishes
Moisture

Le Serum increases hydration by 200% within one hour. Our Hyaluronic Acid + Swiss Vegan Glycogen complex delivers immediate and lasting hydration to vulvar skin, soothing sensitivity and supporting the skin's natural moisture balance over time. 

MICROBIOME BALANCE

Our Microflora Ferment™, a bio-fermented prebiotic and postbiotic complex, is clinically studied to help support a Lactobacillus-favorable intimate environment. By working with the body's natural ecosystem rather than disrupting it, Le Sérum helps maintain the healthy acidic pH associated with intimate microbiome balance, comfort, and freshness. 

SKIN RENEWAL

Swiss-cultured plant stem cells support the proteins that keep skin firm and elastic. With continued use, skin appears smoother, firmer, and more resilient over time.

Brightens Skin

Swiss-cultured plant stem cells and our Biomimetic Renewal Complex® support skin vitality and resilience. With continued use, Le Sérum helps support brighter, more even-looking intimate skin, clinically associated with a 30% reduction in visible hyperpigmentation after 6 weeks. 

STRENGTHENS SKIN BARRIER

Clinically proven to support a 6% increase in skin density after 28 days. Our Biomimetic Renewal Complex® and oat extract work together to reinforce barrier resilience, helping intimate skin feel stronger, softer, and more protected against daily stressors.
