Hyaluronic Acid Can Actually Dehydrate Your Skin (Here's When)
The internet's favorite hydrator has a counterintuitive dark side — in dry air, a humectant with nothing to seal it can pull water out of your skin instead of into it.
Supporting role for Dryness
What Makes This Different
It dissolves makeup with a gentle blend of four esters rather than mineral oil or strong surfactants, and it is fragrance-free, alcohol-free and paraben-free. The formula also carries two hyaluronic acid forms, beta-glucan, licorice-derived soother and Spa Treatment's HAS conditioned-media extract.

Spa Treatment HAS Cleansing Milk Review
Fragrance-Free Makeup Milk
cleanser lotion j beauty Paraben Free Vegan Not Cruelty Free
A gentle, fragrance-free, alcohol-free and paraben-free cleansing milk that dissolves makeup with a blend of mild esters and leaves dry or sensitive skin comfortable. The HAS stem-cell extract is rinsed away before it can matter, isopropyl palmitate is a watch-out for breakout-prone skin, and the Japan-only price is high for a cleanser, but the formula itself is thoughtful.

Reviews of this cleansing milk exist mainly on Japanese beauty sites, and we found none in English with countable volume. Our assessment relies on the brand's official Japanese ingredient list, which we translated into INCI, and on the well-understood behaviour of ester-based cleansers; the US price could not be confirmed.

Review
Full Review
There is a quiet irony at the centre of Spa Treatment's HAS Cleansing Milk. The HAS line is built around an expensive, headline-grabbing ingredient, an extract from cultured human fat cells, and here that ingredient sits in a product that spends about sixty seconds on the face before going down the drain. Whatever the extract might do in a leave-on cream, it is unlikely to do much in a cleanser. Fortunately, the rest of the formula is sensible enough that the milk stands on its own as a gentle makeup remover.
The cleansing work is done by a blend of esters. Triethylhexanoin and cetyl ethylhexanoate lead the list after water, followed by isopropyl palmitate and dicaprylyl carbonate. These light, oil-like ingredients dissolve foundation, sunscreen and sebum, and a small amount of emulsifiers, including glyceryl stearate SE, polysorbate 60 and several polyglyceryl esters, allows the whole mixture to rinse away cleanly with water. There is no mineral oil, no strong surfactant and no alcohol, which is why the milk feels soft rather than squeaky.
The supporting ingredients are designed to leave skin comfortable. Glycerin sits fifth, adding a humectant cushion. Sodium hyaluronate and a cationic hyaluronate, which clings to the skin through rinsing, add to the soft after-feel. Beta-glucan, which the brand sources from split-gill mushroom, and dipotassium glycyrrhizate, a licorice-derived soother, round out the calming side. Spa Treatment's usual botanical set, grape vine, soybean, artichoke, brown seaweed, rock rose and gynostemma, appears too, alongside the HAS extract itself.
In use, the milk is easy and pleasant. One or two pumps on a dry face, massaged in small circles for about a minute, is enough to break down a full face of makeup. It rinses cleanly with lukewarm water and leaves skin soft, with no tightness. There is no fragrance, essential oil or alcohol, which makes it a good option for sensitive skin that dislikes perfumed cleansers. Waterproof mascara may need a dedicated eye makeup remover, but everyday makeup and sunscreen come off without fuss.
The main caution involves oily and acne-prone skin. Isopropyl palmitate is often flagged as potentially comedogenic, and the esters and fatty alcohols can leave a slight residual film if not rinsed thoroughly. In a rinse-off product, the risk is much lower than in a moisturizer, but people prone to breakouts or fungal acne may prefer to follow with a gentle foaming cleanser. Dry and normal skin will usually find a single cleanse sufficient.
The price is the other obstacle. On Spa Treatment's Japanese store, a 150ml bottle costs ¥6,050, which is expensive for a cleanser, and it is mostly sold outside Japan through importers at higher prices. Its US price, where it appears at all, could not be confirmed. Much of that cost reflects the brand's positioning and the HAS extract, which contributes little in a rinse-off product. The ester base itself is similar to many less expensive cleansing milks.
That said, the milk has a few genuine advantages. It is fragrance-free, alcohol-free and paraben-free, which not every premium Japanese cleanser can claim. Its texture is elegant, and the pump makes it easy to use consistently. For people who already use the HAS line and want a matching makeup remover that will not upset dry or sensitive skin, it fits naturally.
Morning use is another option worth mentioning. Many people with dry or sensitive skin find that a full cleanse in the morning is unnecessary, but a quick pass with a milk like this, massaged briefly and rinsed, removes overnight residue from heavy creams without stripping the skin before sunscreen. Because it contains no fragrance or alcohol, it can also be used around the eyes more comfortably than many foaming cleansers, which makes it a practical all-in-one step for people who prefer a minimal routine.
Spa Treatment was founded in 2002 by Wave Corporation in Osaka and built its reputation in Japanese beauty salons. The HAS Aging Care range is its flagship, and the cleansing milk was added in 2020 to complete the basic routine. Like much of the range, it layers a biotech story over a conventional, well-made formula.
There is a broader lesson in how to read a cleanser's label. Ingredients that matter in a rinse-off product are the ones that do the cleaning and the ones that protect the skin while it happens: here, the esters, glycerin and humectants. Expensive actives, whether stem-cell extracts, peptides or vitamins, mostly wash away. Judged by that standard, this milk is a good cleanser with an unnecessary luxury ingredient.
A few practical tips help it perform. Applying to a completely dry face and massaging for a full minute gives the esters time to dissolve makeup. Adding a splash of water at the end helps the milk emulsify before rinsing, which reduces residue. For those with combination skin, a second, gentle foaming cleanse on the T-zone can remove any lingering film.
The verdict is balanced. For dry, normal or sensitive skin that wants a gentle, unscented makeup remover and can buy it at a sensible price, the HAS Cleansing Milk is a comfortable, well-formulated option. For oily or acne-prone skin, or for anyone paying a premium specifically for the stem-cell extract, a simpler and cheaper cleansing milk will do the same job.

Evidence
Science & Expert Perspective
The Science
The milk's cleansing action relies on esters such as triethylhexanoin, cetyl ethylhexanoate, isopropyl palmitate and dicaprylyl carbonate. These non-polar emollients dissolve oil-soluble makeup, sunscreen filters and sebum, while emulsifiers including glyceryl stearate SE, polysorbate 60 and polyglyceryl esters allow the mixture to rinse away with water. Cleansers built on emollients rather than strong surfactants tend to preserve more of the skin's natural lipids, which is why milk cleansers are often recommended for dry or sensitive skin.
Glycerin, sodium hyaluronate and hydroxypropyltrimonium hyaluronate provide humectancy. The cationic hyaluronate is positively charged, allowing it to adhere to the negatively charged skin surface and remain after rinsing, which may contribute to a smoother after-feel. Beta-glucan and dipotassium glycyrrhizate offer soothing properties; glycyrrhizate in particular has anti-inflammatory activity in laboratory and small clinical studies.
Isopropyl palmitate has historically been rated as comedogenic in rabbit-ear models, though those tests overstate the risk for human skin, and the concern is lower in a rinse-off product. Still, people with acne-prone skin may prefer to rinse thoroughly or double cleanse.
Human adipocyte conditioned media extract contains growth factors and extracellular vesicles from cultured fat cells. Research on adipose-derived conditioned media has focused on leave-on or procedure-assisted use, such as with microneedling. In a cleanser with brief contact time, meaningful absorption or benefit is unlikely.
Dermatologist Perspective
Clinicians often recommend gentle, fragrance-free cleansing milks or lotions for patients with dry, sensitive or eczema-prone skin, because they remove makeup and sunscreen without stripping lipids. This formula fits that profile well, with mild esters, humectants and soothing agents and no alcohol or fragrance. Acne-prone patients may be advised to follow with a gentle foaming cleanser or choose an ester-free option. The inclusion of a stem-cell-derived extract in a rinse-off product is unlikely to provide benefit, so patients should not choose this product for that reason. Its value lies in gentle, comfortable cleansing. Thorough rinsing with lukewarm rather than hot water helps preserve barrier lipids.
Guidance
Usage & Recommendations
How to Use
Use it in the evening to remove makeup and sunscreen. With dry hands on a dry face, apply one or two pumps and massage gently in small circles for about a minute, focusing on areas with foundation or sunscreen. Add a splash of lukewarm water and massage briefly to emulsify, then rinse thoroughly. Oily or acne-prone skin can follow with a gentle foaming cleanser. For heavy waterproof mascara, use a dedicated eye makeup remover first. Follow with toner and the rest of the evening routine.
Value Assessment
On Spa Treatment's Japanese store, the 150ml bottle costs ¥6,050, which is high for a cleansing milk, and importers typically charge more; we could not verify a stable US price. A bottle lasts two to three months with nightly use. The formula is gentle and well built, but its ester base is similar to many cheaper milks, and the HAS extract adds cost without benefit in a rinse-off. It makes most sense for existing HAS users who want a matching cleanser, or for anyone who finds it at a reasonable price.
Who Should Buy
People with dry, normal or sensitive skin who want a gentle, fragrance-free makeup remover that leaves the face soft rather than tight will appreciate it. It is a natural fit for existing Spa Treatment HAS users seeking a matching cleanser.
Who Should Skip
Oily, acne-prone and fungal-acne-prone skin types may prefer an ester-free cleanser or a gentle foaming wash instead. Budget-conscious shoppers can find similar gentle cleansing milks for far less money, and nobody should buy it for the stem-cell extract alone, since it rinses away.

Myth vs. Reality
Common Myths
Myth
The stem-cell extract in a cleanser nourishes the skin.
Reality
The HAS extract is rinsed off within a minute, so any benefit it might have in a leave-on product is unlikely to carry over to a cleanser.
Myth
Cleansing milks cannot remove makeup properly.
Reality
This one uses several esters that dissolve foundation and sunscreen effectively; only heavy waterproof mascara may need a dedicated remover.
Myth
A gentle cleanser has to be foaming to feel clean.
Reality
Milk cleansers remove makeup and oil without foam, and they tend to leave dry skin more comfortable.
