Deep Green Tea Cleansing Foam

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.

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.

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.

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.
