Benton is the K-beauty brand that ingredient-obsessed Reddit users discovered about five minutes before anyone else did. Founded in 2011, the brand built its identity around EWG-style transparency, minimal additives, and a deliberate refusal to chase the hype cycles that most Korean skincare brands ride. The Deep Green Tea Cleansing Foam is a neat test case for whether that philosophy actually changes the product, because 'green tea cleanser' is one of the most over-used marketing hooks in the category — most of them contain about as much green tea as a Lipton tea bag that has been briefly waved over the vat. Benton's version actually contains the plant. Ten percent of the water phase is green tea leaf water, not plain water, and three additional fractions — leaf, seed, and root extracts — sit further down the INCI. Whether that matters at the short contact window of a wash-off product is a fair question, but at least you are paying for what is on the label.
Some context on why this line exists: the Deep Green Tea collection arrived in 2018, Benton's answer to the wave of premium green-tea ranges sweeping Korean retail at the time — but pitched at the ingredient-geek end of the market rather than the mass-retail shelf, where prettier packaging usually papers over thinner INCIs.
The cleansing base is a traditional Korean saponified-soap system: myristic, lauric, palmitic, and stearic acid combined with potassium hydroxide to generate a dense, creamy foam that removes sebum, sunscreen residue, and the tail end of an oil cleanser without any drama. The pH lands somewhere in the 9-10 range, which is alkaline enough that you should always follow with a low-pH hydrating toner to return skin to its acid mantle quickly — this is standard K-beauty routine practice and not a flaw of the product, but it is worth stating explicitly because people who cross over from amino-acid cleansers sometimes forget. Glycerin, panthenol, and a small centella asiatica soothing bench cushion the wash enough that it never crosses into 'squeaky-tight' territory for normal or combination skin, though dry and reactive users will feel the alkalinity more than they would with a cream cleanser.
Dig past the soap chemistry and the supporting bench is deeper than the price implies. Sodium lauroyl glutamate — an amino-acid surfactant — is blended into the base to take the edge off the saponified system, which partly explains why the wash finishes softer than a textbook potassium-hydroxide foam. Two species of willow bark extract bring a whisper of natural salicin to the oily-skin brief, houttuynia cordata and pomegranate extend the botanical antioxidant roster, camellia japonica seed oil adds a conditioning cousin to all that camellia sinensis, and polyquaternium-10 with allantoin smooths the post-rinse skin feel. The reflex to write off fatty-acid soaps as automatically too harsh misses this kind of engineering: surfactant class matters less than what surrounds it, and here the cushioning is deliberate.
Using it is about as uneventful as cleanser reviews get, which is actually the highest compliment you can give a face wash. A pearl-sized amount on damp hands whips into a dense, creamy foam — visually satisfying but not performative. Two-fingertip circles around the face for 30-45 seconds, rinse with lukewarm water, pat dry. Skin feels clean without that stripped-plaster sensation, the rosemary oil adds a faint herbal note that most users do not even register, and there is no fragrance-bomb scent to contend with. Makeup removal is competent for light coverage and excellent as a second cleanser — the potassium hydroxide soap dissolves waxes and residual oils more effectively than most amino-acid-based cleansers in the same price tier, which is the main practical reason to choose this over a 'gentler' alternative.
In a routine it earns its keep twice a day: solo in the morning before toner and serum, and as the second step of an evening double cleanse after an oil or balm. It coexists happily with retinoid, azelaic acid, and benzoyl peroxide routines, provided the low-pH toner step follows the wash. Expect degunked skin from the first use, less visible sebum buildup inside a week, and the subtle 'brighter overall tone' the category loves to promise only after three or four weeks of consistent use — honesty demands saying that part is gradual. A 120g tube at twice-daily use stretches to three or four months, which works out to about five dollars a month.
Seven years of steady community coverage and roughly 2,500 aggregated reviews at 4.4 stars have produced a settled consensus. Users consistently name the thorough-but-not-tight cleanse, the fragrance-free build, the dense foam, and the price as the reasons they repurchase; the recurring reservations — the faint rosemary note, the dryness on sensitive skin, the alkaline pH — are the same ones any honest read of the INCI would predict. Notably, the formula has not been reworked since launch, a stability that the ingredient-transparency crowd treats as a feature in itself.
Limitations are real but modest. The alkaline pH is a disqualifier for rosacea, eczema, or actively compromised skin — those faces should stick to cream cleansers or micellar water. The rosemary leaf oil is a small but non-zero sensitizer for the subset of users who react to it. The tube packaging is functional but aesthetically plain, which matters mostly for buyers who care about shelf appeal. And the 10% green tea leaf water, impressive as it is for the category, is still delivering polyphenols into a wash-off product where most of the benefit rinses down the drain within a minute.
The value proposition is where this cleanser settles into its 'quiet recommendation' slot: $17 for 120g of a well-built, fragrance-free, meaningfully active cleanser is genuinely fair, and it slots into nearly any routine that does not specifically require a low-pH formula. For oily, combination, or normal skin looking for a dependable second-cleanse step with actual green tea inside, this is one of the better options in its price tier.
