Better than what’s out there

Ordinary washes rely on harsh soaps and heavy fragrance to mask odor, often causing dryness, irritation, or worse. Undecimber is different. Built specifically for intimate skin, it targets bacteria at the source, neutralizes odor naturally, and leaves you feeling fresh, clean, and confident.

Precision Bacterial Defense

Our lab uses silver nanoparticles, which are safe and effective at fighting bacteria. We mix them into a gel that releases anions and oxygen to achieve a bacteria prevention rate of 99.9%.

Intimate skin is exposed to more than we realize. Our formula uses precision silver technology to defend against harmful bacteria, giving you the confidence of daily protection where it matters most.

E.coli

Studies show that Staphylococcus aureus can be found in the genital region. A study in Baltimore found that 50% of people in an STI clinic carried S. aureus in their genital area.

Candida Albicans

While many fungi need two opposite mating types (similar to male and female) to reproduce, this fungus can also mate with cells of the same mating type under certain environmental stresses.

Odor Control Beyond Intimates

Odor doesn’t stop at the groin. Areas like underarms and the gluteal fold are hotspots for sweat, bacteria, and irritation yet your body soap and shower gel is either too harsh or not effective enough. Undecimber’s Kleanio® V1 targets these areas with precision, gently eliminating odor-causing bacteria without disturbing your skin barrier. Enriched with Japanese persimmon extract, the formula leaves you feeling cool, balanced, and fresh long after the shower ends.

The Shave-Safe Cleanser

Designed with small-molecule hyaluronic acid and dipotassium glycyrrhizate, this formula doubles as an ideal pre- or post-shave wash for intimate skin. Whether using a razor or an electric trimmer, friction and microtears can lead to redness, bumps, or irritation. Our soothing, hydrating ingredients work to calm inflammation, strengthen the skin barrier, and reduce post-shave sensitivity.

Product FAQ

1. Why do men need a dedicated wash for down there?

Your intimate area has different skin, sweat glands, and bacterial balance compared to the rest of your body. Regular soap can strip away natural protection, causing irritation or odor. Undecimber is pH-balanced and made specifically to cleanse, soothe, and protect where it matters most.
2. What’s inside Undecimber that makes it so effective?

We combine silver nanoparticles to target bacteria and odor, Canadian marine mud for deep detox, and 5D hyaluronic acid to keep skin hydrated and smooth — all in one product designed by ex-L’Oréal and Unilever professionals.
3. When should I use Undecimber?

Use it during your daily shower, before or after sex, or post-workout. It’s ideal for keeping you fresh throughout the day and for moments when extra confidence matters most.
4. Can I use it if I’m uncircumcised or have sensitive skin?

Yes. Our formula is dermatologically tested and gentle enough for all skin types, including sensitive skin and uncircumcised users. It cleans effectively without stinging or drying.
5. What are the long-term benefits of using this product?

Consistent use helps maintain healthy hygiene, prevent irritation and odor, and improve skin condition in your intimate area. Think of it as skincare for your most sensitive skin — reducing friction, dryness, and bacterial buildup over time.
6. I’ve never had any irritation or issues down there.Why should I buy this?

Even if you’ve been “fine,” Undecimber isn’t just about solving problems. 
Think of it like skincare or fragrance: it’s not just for you, it’s for your partner too. A clean, well-cared-for intimate area shows respect, boosts confidence, and can make shared moments more comfortable, attractive, and enjoyable. Also minimise chance for your partner to get infected or experiencing discomfort.
