"Meringue-like foam": what a dense bubble cleanser texture is engineered to do

Why foam density affects how much friction cleansing actually requires

A dense, "meringue-like" foam creates more cushioning between fingertips and skin than a thin, watery lather — this means less manual pressure and rubbing is needed to spread the cleanser fully across the face, a genuine mechanical reason a rich foam format suits sensitive or blemish-prone skin that reacts poorly to friction.

Why this matters specifically for skin already dealing with active blemishes

Blemish-prone skin is often already inflamed or has compromised areas around active spots — reducing physical friction during the cleansing step itself (independent of the cleanser's chemical ingredients) is a real way to avoid additional mechanical irritation on top of existing inflammation.

What "mildly acidic pH" is doing alongside the foam texture

Formulating closer to skin's natural pH (rather than more alkaline, as covered in the baking soda cleanser comparison elsewhere in this catalogue) supports barrier function during cleansing — the combination of gentle chemistry (pH) and gentle mechanics (dense foam) addresses two separate aspects of what makes a cleanser suitable for reactive skin.

What 10% centella asiatica extract and the "Hyaluro Complex" are contributing

Centella's calming, barrier-supportive compounds and a multi-form hyaluronic acid complex work to offset the inherent drying tendency of any surfactant-based cleanser — a common, well-established pairing in K-beauty formulations aimed at not leaving skin "tight" after rinsing.

How to judge whether a "rich foam" claim will actually feel that way

Foam density and richness are genuinely dependent on water hardness, water temperature and how much cleanser is used, meaning the exact experience described in marketing can vary by user circumstances — using slightly warm (not hot) water and a modest amount of product typically gets closest to a brand's intended foam texture.
