Rub your palms together to create a soft, creamy lather. Gently apply to your external intimate area and leave on for around 15 seconds to let the hydration, probiotics, and botanical care work their magic. Massage in light circular motions before rinsing.

Rinse thoroughly with warm water. The formula supports your natural microbiome, leaving you feeling hydrated, fresh, and comfortably balanced throughout the day.

Consumer study

9 in 10

women reported less dryness and irritation after switching to Undecimber.

83%

said it felt like skincare, not just soap.

91%

noticed reduced odor within 3 days.

"I experienced less problems with irritation, itching and dryness since I switched to Undecimber"

I have bought many intimate wash products both online and offline. A lot of them are heavily scented and caused dryness and even irritation for me. Even though this brand is definitely not cheap, I do feel more hydrated and I love the slight hint of essential oil scent it has.

"Rarely come across intimate products that specifically target the pain points of menopause"

I have used many feminine products, having lived in South East Asia for over 50 years. A lot of them contain harsh chemicals and do very little to the real issues I face. Women at my age face hormonal changes which cause different level of discomfort.
The first time my daughter got me UNDECIMBER, I have noticed how soft and silky the product texture is. It almost feels like I need just a tiny drop compare to the other brands which are normally quite diluted. Most importantly, it has helped with the discomfort and dryness issues I face.

"A hidden niche intimate brand discovered during my Thailand trip"

My friends and I had heated discussion about different intimate care brands we have bought online. One thing we have come to conclusion is that we shouldn't use just "anything" down there. UNDECIMBER has this cute pink bottle after you take it out from a relatively "cold" packaging but what I am surprised about is the gel, silky texture that come out from this tube. Super hydrating and moisturising, I am amazed. Also loved the smell, it still reminds me of those fancy Thai spa.

"It has helped improve my discomfort and problems during period"

I have been always worried about unwanted odor and stickiness during period which grounded me at home. My gyne has given me some sachets from Undecimber and I noticed immediately the difference from those drugstore washes. It doesn't have strong fragrance to mask the smell, but really adjust our pH and microbiome through their biotech and skincare properties. Honestly, it feels more hydrating than the face wash I am using right now and I stopped worrying about the stickiness in my pants.

Us vs Mainstream

A proper pH level is only part of the story. Many intimate washes claim to be pH balanced, yet still disrupt the vaginal microbiome with harsh preservatives, synthetic fragrances, or sulfates like SLS and SLES. Ingredients such as parabens, triclosan, and methylisothiazolinone can further irritate or strip delicate skin, undermining long-term intimate health.

3 Key Components of Your Vaginal Microbiome

Lactobacillus Crispatus

The critical super defender that maintains appropriate vaginal microbiota, reducing risks of vaginitis and urinary tract infections, promoting good feminine hygiene.

Supports Bacterial Flora

A healthy balance of bacteria is crucial for maintaining the vaginal microbiome's health, preventing infections, and ensuring a healthy pH level. By supporting beneficial bacteria, inulin can help protect against harmful pathogens.

Maintains pH

The vaginal area has a delicate pH balance that is acidic to prevent the growth of harmful bacteria. By promoting the growth of beneficial bacteria, inulin can help maintain the natural pH balance of the vagina, which is essential for its health and for preventing infections such as bacterial vaginosis or yeast infections.

NOT ALL BACTERIA SHOULD BE ELIMINATED

Many intimate care products use harsh disinfectants like Chlorphenesin or Chloramine-T, which can disrupt the delicate vaginal ecosystem.

Research shows that maintaining a healthy pH and microbiome is essential for protecting against harmful bacteria. In healthy women, naturally occurring bacteria form a biological barrier that helps stabilize the vaginal environment and defend against foreign pathogens.
