Every moisturizing routine has a vulnerable moment: the wash. A harsh cleanser can strip away the lipids and natural moisturizing factor that a good moisturizer is trying to replenish, leaving skin tight and more prone to irritation. For a brand built around dry skin, that is a problem worth solving carefully. Carté HD's Moisture Washing Foam is the answer from KOSÉ Maruho Pharma, the company formed in 2019 by KOSÉ and dermatology-focused Maruho. Launched in 2020, it has around 900 reviews on @cosme, and reviewers consistently describe the same thing: skin feels clean but not tight.
The reason lies in its surfactants. Potassium cocoyl glycinate and sodium methyl cocoyl taurate are amino-acid-based cleansing agents. They are made by combining coconut fatty acids with amino acids such as glycine and taurine, and they are known for being among the mildest surfactants available. They interact less with skin proteins and lipids than sulfates or soaps, and cleansers based on them tend to leave the barrier more intact. Sodium cocoamphoacetate, an amphoteric surfactant often used in baby washes, softens the cleanse further and helps create the dense foam.
The rest of the formula supports comfort. Butylene glycol, glycerin and maltitol are humectants that leave a small amount of hydration behind after rinsing. Serine, theanine and acetyl hydroxyproline are amino acids associated with natural moisturizing factor, and glycosyl trehalose and glyceryl glucoside add water-binding. The registered quasi-drug active is dipotassium glycyrrhizinate, a licorice-derived anti-inflammatory widely used in Japanese skincare to reduce roughness. In a rinse-off, contact time is short, but the ingredient fits the product's gentle design. Unlike most Carté HD products, it contains no heparin-like substance, which is reserved for the leave-on moisturizers.
The formula is fragrance-free, paraben-free, sulfate-free and oil-free, preserved with phenoxyethanol alone. That makes it suitable for nearly every skin type, including sensitive, eczema-prone and rosacea-prone skin, and for people using retinoids or exfoliating acids, who benefit from gentle cleansing.
In use, two or three pumps dispense a dense, fine-bubbled foam that feels cushiony on the skin. Carté suggests letting the foam wrap the face and gently massaging rather than scrubbing. It rinses quickly and leaves skin soft and comfortable. Oily skin can use it too; mild surfactants still remove oil and sweat effectively, although some people with very oily skin may want a slightly stronger cleanse in hot weather.
The foam is not designed to remove makeup or water-resistant sunscreen. Carté pairs it with its Cleansing Oil Gel as a double cleanse, and any oil-based remover will work as the first step. Used alone in the morning, though, it is an ideal wash for skin that has only accumulated sweat and sebum overnight.
It helps to think about how a cleanser fits into dry-skin care as a whole. Many people with dry or sensitive skin spend money on rich moisturizers while washing twice a day with a cleanser that strips the very lipids those moisturizers are trying to replace. Switching to a mild foam like this one is often one of the simplest and most effective changes they can make. In a dermatology clinic, it is common advice for patients with eczema, rosacea or retinoid irritation, and the difference can be noticeable within a week or two: less tightness after washing, less redness and fewer flaky patches.
Water temperature and technique matter as much as the product. Lukewarm water dissolves less of the skin's lipids than hot water. Letting the foam do the work, with gentle circular movements rather than scrubbing, avoids friction. Patting dry with a soft towel and applying the next step within a minute keeps skin from losing water during the gap. For people with very dry skin, washing only at night and rinsing with water in the morning can reduce irritation further, and this foam is mild enough to make that a comfortable routine.
There is also an argument for using it alongside stronger treatments. Someone using benzoyl peroxide or a retinoid for acne, for example, will tolerate those actives better if the cleanser is not adding to the irritation. Pairing a gentle foam with a potent treatment is a common approach for exactly that reason.
A small practical note from reviewers: foam pumps can clog if residue dries in the nozzle, so rinsing the pump head occasionally keeps it working smoothly. Refill pouches reduce cost and allow the bottle to be reused.
The biggest obstacle for international shoppers is getting hold of it. In Japan, the 150 ml bottle costs about ¥1,320, very good value for such a gentle formula. Outside Japan, buyers generally rely on online importers, and no verified US price was available.
KOSÉ is a legacy cosmetics company, and Carté HD's partnership with Maruho gives the line a dermatology focus that shows in this careful formulation. Quasi-drug approval covers the active ingredient, though product-specific trials are not published in English. For anyone with dry or sensitive skin who wants a cleanser that respects the barrier, this is an excellent choice, and one of the clearest examples of how the gentlest surfactants can still deliver a satisfying foam.
