PH Cleansing Gel Foam is Dr.G's foam cleanser (300ml), built around Bifida Ferment Lysate and Glycerine. It is used as the first step of a routine, to remove makeup, sunscreen and the day's buildup. This is the same formula Korean shoppers buy off the shelf in Seoul, not a version built for US retail.

How it works
The PH Cleansing Gel Foam is a 300ml gel cleanser, used as your first step, morning and evening, on skin wet with lukewarm water. The ferment it is built around is Bifida Ferment Lysate, named twenty-first on its own ingredient list. The same list carries Streptococcus Thermophilus Ferment, Pollen Extract and Olea Europaea (Olive) Oil Unsaponifiables, so the ferment is not the only thing on it worth naming. How much of the Bifida Ferment Lysate stays on the skin, and for how long, is decided by the gel cleanser format rather than by the list alone. This is the Original Korean Formula, the gel cleanser Dr.G sells in Korea, Bifida Ferment Lysate and all.
Key benefits
- Bifida Ferment Lysate, the ferment this gel cleanser is built around
- Streptococcus Thermophilus Ferment on the same list, a ferment
- Pollen Extract on the same list, a plant extract
- Olea Europaea (Olive) Oil Unsaponifiables and Glycine Soja (Soybean) Oil on the same list, emollients
- Fructooligosaccharides further down the same list
- Bifida Ferment Lysate named twenty-first on the manufacturer list printed on this page
How to use
- Work into a lather on damp skin, massage over the face, then rinse thoroughly with lukewarm water.
Where does this gel cleanser go in my routine?
As your first step, morning and evening, on skin wet with lukewarm water. Nothing goes under it: this gel cleanser is the step everything else in the routine lands on top of. If you are adding it to a routine you already like, give it a week on its own first, so what you see is the Bifida Ferment Lysate and not three changes at once.
Is this the Korean-market gel cleanser or a US version?
The Korean-market one, Bifida Ferment Lysate and all. We match this gel cleanser to its Korean barcode before it reaches the shelf, which is the check that tells you which market release you are holding.
What else is on the list besides Bifida Ferment Lysate?
Streptococcus Thermophilus Ferment, Pollen Extract and Olea Europaea (Olive) Oil Unsaponifiables. The order they are printed in on this gel cleanser's panel is the order on the box, so you can see where Bifida Ferment Lysate sits relative to them. Further down the same panel: Glycine Soja (Soybean) Oil and Fructooligosaccharides.

Ingredient list read from inkeedecoder.com on 10 September 2026.
23 of 27 explained
- Water solvent
- Water is the base almost every serum, toner and cream is built on. It dissolves the water-loving ingredients and sets how light the finished texture feels. On an INCI list it is usually first, which only means it is the largest single ingredient by weight.
- Glycerine humectant
- Glycerin is the most used humectant in skincare. It draws water into the outer layer of skin and holds it there, and it is one of the very few ingredients whose hydrating effect is settled science rather than marketing. Higher amounts feel tacky, which is why it is usually blended.
- Disodium Cocoamphodiacetate surfactant
- Disodium Cocoamphodiacetate is a very mild coconut-derived surfactant used in cleansers for reactive skin and around the eyes.
- Disodium Cocoyl Glutamate surfactant
- A glutamic-acid surfactant from coconut fatty acids, and one of the mildest cleansing agents in wide use. It produces a soft, low foam.
- Sodium Chloride thickener
- Sodium Chloride is salt. In a cleanser it thickens the liquid; in a mask or essence it balances the mineral content of the water phase. It has no active role.
- Hydroxypropyl Starch Phosphate thickener
- Hydroxypropyl Starch Phosphate is a modified starch used to thicken and to take the sticky edge off a formula, leaving a powdery finish.
- Citric Acid pH adjuster
- Citric Acid is used in tiny amounts to bring a formula to the pH its actives need, not as an exfoliant at that level. It is an AHA, so at much higher concentrations it can also exfoliate.
- Acrylates/C10-30 Alkyl Acrylate Crosspolymer thickener
- This is a carbomer relative with fatty side chains, so it thickens and stabilises an emulsion at the same time. It gives a light gel-cream body rather than a heavy one.
- Caprylyl Glycol preservative booster
- Caprylyl Glycol is a glycol that conditions skin and, more importantly, strengthens a preservative system so less of the traditional preservative is needed. It appears in most modern formulas built without parabens.
- Coco-Betaine surfactant
- Coco-Betaine is a coconut-derived secondary surfactant used to build foam and make a cleanser milder.
- 1,2-Hexanediol humectant
- 1,2-Hexanediol is a glycol used for two reasons: it holds water like glycerin, and it makes a formula harder for microbes to live in, so less traditional preservative is needed. Korean formulas use it heavily for that second reason.
- Glyceryl Caprylate emulsifier
- Glyceryl Caprylate is a mild emulsifier that also makes a formula less hospitable to microbes, so it is often part of a preservative-free system.
11 more explained
- Coco-Glucoside surfactant
- Coco-Glucoside is a mild sugar-derived surfactant used in gentle cleansers, usually with a second surfactant to build foam.
- Disodium EDTA chelator
- EDTA is a chelator: it locks up trace metal ions from water and packaging that would otherwise turn a formula cloudy, off-colour or rancid. It does nothing to skin and appears at a fraction of a percent.
- Butylene Glycol humectant
- Butylene Glycol is a small glycol that does two jobs at once: it holds water in the top layer of skin and it dissolves plant extracts and actives that plain water cannot. It also thins a formula, which is why watery Korean essences lean on it.
- Leuconostoc/Radish Root Ferment Filtrate preservative
- This is radish root fermented by Leuconostoc, the culture behind kimchi, then filtered clear. It carries natural antimicrobial peptides, so formulas use it in place of part of a conventional preservative.
- Fructooligosaccharides humectant
- Fructooligosaccharides are short fructose chains used as humectants and as food for the skin's own resident microbes.
- Polyglyceryl-10 Oleate emulsifier
- Polyglyceryl-10 Oleate is a mild sugar-derived emulsifier and solubiliser used where a formula must stay clear.
- Bifida Ferment Lysate ferment
- Bifida Ferment Lysate is a bifidobacteria ferment with the cells broken open. It is the ingredient behind the first-essence category and is used for the look of tired, reactive skin.
- Streptococcus Thermophilus Ferment ferment
- Streptococcus Thermophilus Ferment is a yoghurt-culture ferment. It is used for its conditioning effect on the outer layer of skin.
- Hydrogenated Lecithin emulsifier
- Hydrogenated Lecithin is lecithin with its unsaturated bonds filled in, which makes it far more stable. It emulsifies and is the standard shell for the liposomes that carry actives into the outer layer of skin.
- Olea Europaea (Olive) Oil Unsaponifiables emollient
- The fraction of olive oil that cannot be turned into soap, where its sterols and squalene concentrate. It softens skin and helps hold water in.
- Pollen Extract plant extract
- Extract of flower pollen collected by bees. Pollen carries amino acids, sugars, vitamins and flavonoids, and the extract is used as a conditioning ingredient.

Worth knowing
- Patch test this gel cleanser on a small area and wait a day before using it more widely, especially with Bifida Ferment Lysate on the list.
- Introduce this gel cleanser on its own for the first week, so anything your skin does is traceable to the Bifida Ferment Lysate rather than to three changes at once.
