Japan's First*¹ Vaginal Cleanser to Pass Both 'Mucosal Irritation Test' and 'Sensitive Skin Patch Test' — Introducing 'Lunaclear,' Setting a New Standard of Gentleness for Intimate Care Against Odor and Itchiness

Introducing 'Lunaclear,' the first*¹ vaginal cleanser in Japan to pass both the 'vaginal mucosal irritation test' and the 'sensitive skin patch test.'

'Even products used on delicate areas—could the “skin” aspect be overlooked?'

In recent years, the term 'femcare' has gained widespread recognition, and the market for women's self-care products—such as menstrual supplies, lubricating gels, intimate soaps, and moisturizers—is expanding rapidly.

Among these, vaginal douches have drawn attention as regulated medical devices used for self-care of the intimate area, particularly for managing odor and itchiness, at the end of menstruation, or when discharge is concerning.

However, because such products are applied directly to sensitive zones, many users harbor concerns:

'It's called a medical device—but is it truly gentle on the skin?'

'Does it cause any irritation?'

'Can I really trust this product?'

While some conventional vaginal douches undergo vaginal mucosal irritation testing,

our investigation of publicly available information revealed no other regulated medical device vaginal douches that have passed both the 'vaginal mucosal irritation test' and the 'sensitive skin patch test.'

Young people, seniors, those with sensitive skin—everyone uses products on delicate areas. Is testing solely for mucosal safety sufficient?

Because products are used on intimate zones, safety evaluations must consider not just mucous membranes but also skin sensitivity.

This principle forms the core development concept behind Lunaclear.

Lunaclear has undergone two safety evaluation tests, making it the first*¹ vaginal douche sold in Japan to achieve dual certification as a regulated medical device under both the 'vaginal mucosal irritation test' and the 'sensitive skin patch test.'

The 'vaginal mucosal irritation test' verifies safety for vaginal use. In contrast, the 'sensitive skin patch test'—commonly used for low-irritation skincare products—evaluates whether application to the skin of individuals with sensitive skin under dermatological supervision causes irritation.

Produced by a trusted domestic manufacturer with rigorous quality and safety controls from assembly through final inspection

Thoughtful formulation designed with intimate health in mind

Beyond safety assessments, Lunaclear features a meticulously designed formula, including a 12-component additive-free formulation*².

Additionally, it contains moisturizing beauty ingredients such as lactic acid, lactobacillus, and hyaluronic acid, helping maintain moisture in the intimate area and supporting the goal of a healthier, more beautiful vaginal environment.

It's not just about cleansing—it's a product thoughtfully designed for gentle, comfortable use.

Vaginal care tailored to women's bodies

Intimate zone care is increasingly recognized not only when discomfort arises but also as a form of self-care where women connect with their bodies.

Lunaclear is a disposable-type vaginal douche designed for quick care at key moments—such as when dealing with odor, itchiness, wanting to finish menstruation faster, or noticing unusual discharge.

With compact, individually packaged units, it's easy to carry and convenient to use not only at home but also while traveling or before dates.

We aim to create products that seamlessly integrate into daily routines, empowering women to continue self-care confidently and naturally.
