Conclusion

A foaming cleanser characterised by its light, airy foam and a distinctive “squeaky-clean” sensation during rinsing. While leaving a moisturised feel after cleansing, it gradually transitions to a smooth, silky after-feel.

The foam is exceptionally light and spreads easily across the face. During cleansing, the bubbles glide smoothly over the skin, making it easy to wash with minimal feeling of friction.

Another distinctive feature is the unique “squeaky-clean” sensation experienced during rinsing. This makes it easier to recognise when the foam has been fully removed, helping to identify the end of the rinse more intuitively.

Immediately after cleansing, the skin has a slightly tacky, skin-to-skin adhesion-like feel, which gradually settles into a smoother, silkier finish.

Note: This review is based on use on normal to oily skin (with oilier T-zone). Those with dry skin may find the finish slightly more on the fresh side.

Skin Finish

Evaluation conditions

This review was conducted after acclimatisation for at least 15 minutes in a controlled environment (22°C ±3°C / 55% ±5% humidity).

Assessment combines sensory experience with interpretation based on ingredient characteristics and formulation design.

The finish leaves a moisturised feel while the skin surface feels smooth and silky.

Dryness-related tightness was minimal. Looking at the ingredient list, the formula contains a variety of moisturising ingredients, including sugars, ceramides and amino acid derivatives, which may help explain the moisturised after-feel observed during testing.

The initial moisturised sensation gradually settles over time, leaving skin feeling smooth without noticeable stickiness.

Experience

Foam

Using the manufacturer’s recommended three pumps produces a very light, airy foam.

Vaserhythm moist foaming face wash fine foam

👉 The foam spreads effortlessly and is easy to distribute evenly across the face.

While the foam is generally fine-textured, it also contains some slightly larger bubbles. These larger bubbles tended to burst more readily, resulting in some changes to the foam structure during cleansing. However, even when massaging the foam in circular motions, the finer foam layer remained largely intact and maintained sufficient cushioning throughout use.

The foam volume per pump is approximately 1g, which is within the standard range for foaming cleansers.

During cleansing

The foam spreads easily and glides smoothly across the skin.

One of the product’s most distinctive characteristics is the unique “squeaky-clean” sensation experienced during rinsing.

This makes it easier to recognise when the foam has been fully rinsed away, providing a clear indication that cleansing is complete.

Key Characteristics

・Light, airy foam that spreads easily

・Fragrance-free

・Easy to tell when the foam has been fully rinsed away

・Relatively good rinseability

👉 The lightweight foam feels comfortable during cleansing, while the noticeable change in skin feel during rinsing adds to the overall experience.

After-feel

・Immediately after cleansing: moisturised feel

・After 3 minutes: the moisturised feel settles slightly, revealing a smoother, silkier skin texture

・Tightness: relatively minimal

👉 Changes over time were gradual, with the skin maintaining a comfortable, hydrated after-feel.

How to use

・Wet the face with water or lukewarm water

・Dispense 2–3 pumps

・Gently spread the foam across the face

👉 Rather than rubbing vigorously, allow the foam to glide over the skin to better appreciate the lightweight foam texture that characterises this product.

Best for

✔ A good fit if you :

・Enjoy light, airy foam textures

・Prefer the convenience of a ready-made foaming cleanser

・Value easy rinsing

・Like a moisturised after-feel

・Prefer fragrance-free products

✔ Worth noting if you :

・Prefer a very fresh, squeaky-clean finish

・Prefer dense, highly elastic foam

・Avoid products containing alcohol

How it’s designed

Cleansing System

The cleansing system is built around amino acid-based surfactants combined with amphoteric surfactants.

・Amino acid-based surfactants (Potassium Cocoyl Glycinate, Sodium Lauroyl Methylaminopropionate)

・Amphoteric surfactants (Sodium Cocoamphoacetate)

👉 This combination appears to be designed to balance cleansing performance with skin mildness.

Why the distinctive rinsing sensation occurs

・Dihydroxypropyl Arginine HCl

👉 This ingredient is expected to have an affinity for the skin and may contribute to both the distinctive “squeaky-clean” sensation experienced during rinsing and the moisturised feel that follows.

During testing, a noticeable change in skin feel was observed compared with many conventional foaming cleansers.

Why the after-feel remains moisturised

・Petrolatum

👉 Highly purified petrolatum that has been micronised may help support moisture retention after cleansing.

In addition, the formula contains a combination of:

・Sugar-derived moisturisers

・Dihydroxypropyl Arginine HCl

・Several ceramides

Together, these ingredients appear to support the moisturised after-feel experienced after washing.

Formulation Concept

A formulation designed to balance the moisturising feel associated with petrolatum and gentle cleansing provided by amino acid-based surfactants.

Alongside petrolatum, which is reflected in the brand name itself, the formula contains a variety of moisturising ingredients and ceramides, suggesting a strong emphasis on maintaining skin comfort after cleansing.

At the same time, amino acid-based surfactants are used as the primary cleansing agents, indicating consideration not only for cleansing performance but also for skin comfort.

The formula also contains ethanol. Although some larger bubbles were observed to burst during cleansing, causing minor changes to the foam structure, the finer foam layer remained relatively stable and the lightweight texture and cushioning effect were largely maintained.

According to a related manufacturer patent, combining maltitol with amino acid-based and amphoteric surfactants can improve the quality of foam dispensed from a foaming pump dispenser¹.

Given the combination of lightweight foam and adequate foam stability observed during testing, it is possible that a similar formulation philosophy has been incorporated into this product.

Appearance & Packaging
