Ingredients

INERTIA Feminine Cleanser was created by a female scientist from KAIST who understood women’s intimate health not just as research, but as lived experience.

Formulated with 3X Microbiome Care, it helps protect and balance the delicate Y-zone exposed to daily external stressors. Infused with glacial water for freshness, pre- & probiotics to support pH balance, and mannose & cranberry to strengthen intimate health, this micro-foaming wash provides optimal comfort.

Enhanced with natural essential oils to help ease PMS and a light, refreshing citrus aroma from botanical extracts, it makes daily care feel as soothing as it is effective.

No harsh chemicals—just science-backed care designed for women, by women.

1. Wash your hands thoroughly and rinse the external area with water.
2. Pump 2–3 times and gently cleanse the vulva with the foam.
3. Rinse well with lukewarm water to remove any residue.

Norwegian Glacial Water – helps maintain cleanliness and skin balance.
Pre- & Probiotics – support gentle pH balance, hydration, antioxidant defense, and protect against skin oxidation.
Mannose & Cranberry – prevent harmful bacteria (like E. coli, responsible for up to 85% of UTIs) from adhering, helping to protect the intimate area from infection.

Frequently Asked Questions
Can I use a feminine wash every day?
Yes—our formula is gentle enough for daily use. Most women feel fresh with once daily use, and you can use it twice on heavier days or after workouts.
Will it disrupt my natural PH BALANCE?
No—our cleanser is designed with pre- & probiotics to support the natural PH BALANCE (around 4.5), keeping the Y-zone healthy without over-cleansing.
What makes this different from regular body wash?
Regular body wash can be too harsh for sensitive intimate skin. Our formula is dermatologically tested, pH-balanced, and enriched with ingredients like Norwegian GLACIAL WATER and CRANBERRY extract, made specifically for women’s intimate care.
