Conclusion

Designed with sensitive skin in mind, this cleanser combines amino acid-based surfactant × a weakly acidic pH × oil-based ingredient to help minimise stress on the skin during cleansing while aiming to maintain moisture after washing.

The formula is set within the skin’s natural weakly acidic pH range, commonly described as slightly acidic, reflecting consideration for the skin’s barrier environment.

The finish is light and fresh, leaning towards a smooth, non-residual feel.

It is a pump-type cleanser that dispenses a fine foam, making it easy to use without the need for manual lathering.

The primary cleansing agent is amino acid-based surfactant, reflecting a formulation designed to balance cleansing performance with potential impact on the skin.

Furthermore, by combining a water-soluble moisturising ingredient with oil-based component that blend well with the skin, the formulation is designed with the expectation of helping to reduce post-cleansing dryness.

This review is based on use with normal to slightly oily skin (particularly oil-prone T-zone). Those with dry skin may perceive the finish as more cleansing/refreshing.

Our take

Evaluation conditions

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

The evaluation combines actual usage experience with analysis based on ingredient properties and formulation design.

Immediately after rinsing, there is a light squeaky-clean sensation, although less pronounced than typical soap-based cleansers.

There is minimal residue, resulting in an overall clean and fresh finish.

Experience

Foam

Using the recommended two pumps produces a fine, uniform foam, as shown in the image below.

foam

👉 The foam has a moderate density, making it easy to handle during use.

foam zoom in

Each pump dispenses approximately 1g of foam, which is within *the standard range for foaming cleansers.

During cleansing

During rinsing, there is little to no slippery residue, and the foam rinses away smoothly.

Key characteristics

・Good rinse-off performance

・Fragrance-free with minimal scent

👉 The formula allows for a smooth and efficient rinsing experience.

The slight squeaky sensation also helps signal that cleansing is complete.

After-feel

・Immediately after: fresh, non-greasy feel

・After ~3 minutes: little to no tightness or discomfort

👉 There are minimal noticeable changes over time, resulting in a relatively stable skin feel.

How to use

・Use 2 pumps

・Cleanse by gently enveloping the face with foam

👉 Cleansing by softly wrapping the skin in foam helps reduce physical friction.

Best for

✔A good fit if you:

・Prefer a formula designed with sensitive skin in mind

・Want a quick, no-lather foam cleanser

・Enjoy a light, fresh finish

・Prefer fragrance-free products

・Are looking for a finish that feels comfortable over time

✔ Worth noting if you:

・Prefer a strong, squeaky-clean feel

・Like a more richly cushioned foam and may use a larger amount per wash

・Enjoy fragranced cleansing products

How it’s designed

Cleansing system

Primary surfactant:

・Amino acid-based (Potassium Cocoyl Glutamate)

👉 Within amino acid-based surfactants, it tends to leave a slightly squeaky-clean finish

・Amphoteric (Sodium Cocoamphoacetate)

・Anionic (Sodium Cocoyl Methyl Taurate)

👉 Support foam formation and stability

・Nonionic (PEG-60 Hydrogenated Castor Oil, PEG-60 Glyceryl Isostearate)

👉 Help solubilise and stabilise oil-based ingredients within the formulation

In addition, the pH is adjusted to a slightly (weakly) acidic range close to that of healthy skin.

Why the finish feels smooth

・Triethylhexanoin

👉 Likely contributes to a light, smooth skin feel by forming a thin layer on the skin surface.

Formulation concept

Amino acid-based surfactant × weakly acidic pH × oil-based ingredient

👉 Designed to balance skin comfort during cleansing with moisture retention after washing
