The Truth About Pore Strips, Pore Vacuums, and 'Shrinking' Your Pores
You cannot shrink a pore. But you can change how visible it is — and almost everything sold to 'minimize' pores is pulling the wrong lever.
It is a foam gel with real calendula petals suspended in it and a declared 7,396 ppm calendula extract, built on a sodium C14-16 olefin sulfonate that the brand mitigates more thoroughly than most, with hydroxysultaine, cocoyl glycinate and three glucosides, and then dressed in a fifty-three-ingredient tail of six hyaluronates, four acids, ectoin, vitamin C and a dozen botanicals that read as a serum's list on a rinse-off; fragrance-free and fifteen dollars, it is a good oily-skin foam with a sensitive-skin costume.
A rich-foaming, fragrance-free gel for oily and combination skin wearing a sensitive-skin costume: real calendula petals and a declared three-quarters of a percent extract over a sodium C14-16 olefin sulfonate that the brand mitigates more thoroughly than most, with glycerin, allantoin and panthenol for the rinse and a fifty-three-ingredient tail of acids, hyaluronates, ectoin, vitamin C and a dozen botanicals that belongs on a serum, for fifteen dollars. It cleans well and cheaply and is the wrong wash for the reactive faces the flower attracts; oily skin gets a good deal, and everyone else should read the second line.
Fifteen months on sale since a June 2025 launch and ten reviews at a 4.9 on the brand's store give this cleanser a thin record, and the brand declares its calendula in ppm and publishes no testing; the assessment rests on the fully disclosed fifty-three-ingredient list, the well-documented behaviour of its surfactant class and the leave-on literature on calendula rather than on user experience.

The petals sell the tube. Real calendula, whole, suspended in a translucent yellow gel, is the kind of detail that makes a cleanser look like a skincare treat, and the brand backs the look with a number, calendula flower extract at 7,396 ppm and petals at 1,000 ppm, roughly three-quarters of a percent of marigold in the gel. Marigold has a genuine literature, wound healing and anti-inflammatory effects in leave-on preparations at higher doses, and a rinse-off at this dose gets a modest soothing note and a colour from it; what it does not get is a gentler surfactant, and the second ingredient in this cleanser is sodium C14-16 olefin sulfonate, one of the stronger sulfate-free anionics on the market. The tube is a good oily-skin foam with a flower in it, and the flower should not be mistaken for the formula.
The formulator, to be fair, has done more than most to soften that lead. Cocamidopropyl hydroxysultaine at fourth, sodium cocoyl glycinate at fifth, lauryl glucoside at seventh and decyl and coco-glucoside further down are four mitigating co-surfactants where the brand's own family wash uses two, glycerin at third and propylene glycol laurate at eighth cushion the rinse, and the result is a dense, generous foam that cleans oily and combination skin thoroughly and rinses fresh and matte without the squeak a plain olefin sulfonate leaves. Then comes the tail, and it is a long one: a hibiscus ferment, green tea, red pine, mugwort, bay laurel, hinoki, apple, saw palmetto, coffee and tomato extracts, six hyaluronate forms, allantoin, panthenol, ectoin, lactic acid, salicylic acid, gluconolactone, a triglyceride, ascorbic acid, tocopherol, capryloyl salicylic acid and xanthophylls, fifty-three ingredients in a product on the skin for under a minute, of which the glycerin, the allantoin and the panthenol survive the rinse and the rest goes down the drain. Only the two salicylates have any route into a pore, and their positions make that a slight assist on the nose at most. There is no fragrance, alcohol or silicone, and the brand's habit of listing a serum's worth of botanicals on a wash is on full display.
In use it is a pleasure for the skin it suits. A hazelnut of petal-flecked gel foams in wet hands into a dense, creamy lather that a cream cleanser would envy, glides over the face, lifts sunscreen and the day's oil in thirty seconds and rinses completely; oily and combination skin comes out fresh, matte and balanced, which is what the tube means by balancing, and normal skin gets a thorough morning wash. Dry skin feels the olefin sulfonate within a few days of twice-daily use as tightness across the cheeks, sensitive and eczema-prone skin has the surfactant and the mugwort, bay and hinoki extracts to contend with, and the honest routine for both is the brand's centella or beta-glucan cleansers, which are built on isethionate, glycinate and emollients rather than on foam power. The acids at the tail change nothing a user can see, the six hyaluronates change nothing a user can feel, and the calendula is a faint herbal note and a pleasant colour.
The pH claim on the tube is the one part of the balancing story that holds. Citric acid and tromethamine at the middle of the list buffer the gel to a mildly acidic range, which matters with an olefin sulfonate because the surfactant is harsher at alkaline pH and because an acidic wash leaves the skin's surface closer to where it started; the brand prints no figure, but the buffer pair is the sign of a formulator who set one. It does not make the surfactant mild, and it does make the foam kinder than the same molecule in a cheaper, unbuffered gel.
The brand's list-writing deserves a word, because it is the pattern across its range. IUNIK prints ppm figures that let a buyer see exactly what a headline means, which is admirable, and it also loads its lists with botanical and active tails that belong on leave-on products, which is the opposite habit and one that turns a fifteen-dollar foam into a fifty-three-ingredient document. On a serum that tail is at least in contact with the skin; on a rinse-off it is marketing, and the sensitive-skin buyer who reads calendula and ectoin and six hyaluronates on a cleanser is being invited to expect a gentleness the surfactant does not deliver. The gel has fifteen months of sale and ten reviews on the brand's store, no published testing and a declared calendula dose, and the assessment rests on the list.
Fifteen dollars for 150 ml is about six dollars a month at a hazelnut twice a day, cheap for a fragrance-free foam with a declared botanical dose and a genuinely good lather, and the value is real for oily and combination skin that wants a thorough, unscented wash with a little charm in the tube; the petals and the tail cost nothing, and the calendula oil in the same line makes a sensible first cleanse before it. Dry, sensitive, rosacea-prone and eczema-prone skin should take the brand's gentler cleansers, anyone expecting the acids to exfoliate should buy a leave-on BHA, and anyone who bought it for the flower should enjoy the flower and trust the foam. Petals in the gel, a strong surfactant under them, and a good cheap wash for the skin that can take it.
The hero actives that drive this product's performance.
| Ingredient | Function | Evidence |
|---|---|---|
| Sodium C14-16 Olefin Sulfonate with Hydroxysultaine, Cocoyl Glycinate and Glucosides | Second, the strong, sulfate-free anionic that gives a gel its rich foam, softened here by cocamidopropyl hydroxysultaine fourth, sodium cocoyl glycinate fifth, lauryl glucoside seventh and two more glucosides further down, which is more mitigation than most olefin sulfonate washes bother with; the result is a foam that cleans oily and combination skin thoroughly and rinses less tight than its lead ingredient would alone, and still a wash that dry or reactive faces should treat as an evening cleanser rather than a twice-daily one. | Not yet assessed |
| Calendula Officinalis Flower Extract (7,396 ppm) and Petals (1,000 ppm) (0.74%) | Ninth and tenth, the marigold extract at a declared 7,396 ppm, about three-quarters of a percent, with whole petals at 1,000 ppm suspended in the gel for the look; calendula has a real wound-healing and anti-inflammatory literature in leave-on preparations at higher doses, and in a rinse-off at this dose it is a modest soothing note and the reason the gel is yellow and the tube says balancing. | Not yet assessed |
| Salicylic Acid, Capryloyl Salicylic Acid, Lactic Acid and Gluconolactone | Fortieth, forty-ninth, thirty-ninth and forty-third of fifty-three, a beta hydroxy acid, its lipophilic ester, an alpha hydroxy acid and a polyhydroxy acid, all at the tail of a rinse-off with under a minute of contact, where only the two salicylates have a plausible route into a pore; they let the brand call the gel pore-balancing and contribute a slight keratolytic assist on the nose at most, and the wash is not an exfoliating cleanser in any working sense. | Regulator-approved for Blackheads · emerging certainty |
| Glycerin, Allantoin, Panthenol and Six Hyaluronates | Third, thirty-second, thirty-fifth and scattered through the tail, the humectant and calming set that survives the rinse and keeps the after-feel from squeaking; glycerin at third does most of that work, allantoin and panthenol add a little calm, and the six hyaluronate forms are the brand's count for the label in a product where they are rinsed away. | Not yet assessed |

cleanser
AM & PM
A hazelnut of gel lathered in wet hands and massaged for thirty seconds to a minute, then rinsed, as the morning wash for oily skin or the second step after the brand's calendula cleansing oil at night; dry and sensitive skin should keep it to evenings and use the brand's milder centella or beta-glucan cleansers otherwise. A leave-on BHA does the pore work the tail acids only hint at.
Thoroughly clean, matte, fresh-feeling skin from the first wash, with the olefin sulfonate doing the work and the glycerin and glucosides keeping the rinse from squeaking; oily skin feels balanced within days and dry skin feels the surfactant within a week of twice-daily use. The calendula soothes slightly during the wash, and the acids at the tail change nothing a user can see; a cleanser changes nothing beyond the rinse.
The cleanser's behaviour follows its surfactant system. Sodium C14-16 olefin sulfonate is a high-foaming anionic with an irritation potential closer to the alkyl sulfates than to amino-acid and glucoside surfactants; the mild-cleansing literature, including a 2004 review in Dermatologic Therapy on the impact of cleansers on the skin barrier, describes how amphoteric and amino-acid co-surfactants, nonionic glucosides and humectants reduce the protein binding and lipid extraction of a strong anionic, and this formula applies that mitigation more thoroughly than most, with cocamidopropyl hydroxysultaine, sodium cocoyl glycinate, three glucosides and glycerin. Glycerin, allantoin and panthenol partly survive the rinse and account for the comfortable after-feel on normal skin.
Calendula officinalis has a real but leave-on literature: a 2023 review in Pharmaceuticals summarised its anti-inflammatory, antioxidant and wound-healing properties, attributed to triterpenoids, flavonoids and carotenoids, with clinical evidence concentrated in ointments and creams for wounds and radiodermatitis; at a declared 7,396 ppm extract and 1,000 ppm petals in a rinse-off, its contribution is a modest soothing note. The tail of six hyaluronate forms, ectoin, ascorbic acid, tocopherol and a dozen botanical extracts sits at positions and contact times that preclude a measurable effect; salicylic acid and capryloyl salicylic acid are lipophilic enough to enter follicles during the wash at a level that makes them an assist rather than an exfoliant, and lactic acid and gluconolactone are water-soluble and inactive in a rinse-off.
The formula contains no fragrance, alcohol, sulfate or silicone; the olefin sulfonate is the drying agent of note, and calendula, mugwort, bay laurel and hinoki extracts are recognised or occasional sensitisers for the minority reactive to them.
A fragrance-free foaming gel on a mitigated olefin sulfonate is a reasonable daily cleanser for oily, combination and acne-prone skin, and clinicians would regard this one as competent for that group while steering dry, atopic, rosacea-prone and barrier-impaired patients toward a syndet or amino-acid cream wash, since the lead surfactant and the botanical tail are both avoidable risks for reactive skin whatever the calendula on the tube suggests. The calendula would be credited with a modest soothing note at its declared dose, the acids and hyaluronates dismissed as rinse-off label content, and a leave-on salicylic acid recommended for anyone whose goal is pore care; the mugwort, bay and hinoki extracts would be flagged for contact-allergy patients.
Wet the face, squeeze a hazelnut of gel into damp hands, work it into a dense foam and massage over the face for thirty seconds to a minute, then rinse thoroughly with lukewarm water. Oily and combination skin can use it morning and night; normal skin once a day; dry skin in the evening only, or not at all. At night it follows the brand's Calendula Complete Cleansing Oil on full-makeup days, and a leave-on BHA afterwards does the pore work the tail acids cannot. Avoid the eye area, and patch-test if sensitised to marigold or mugwort.
Fifteen dollars for 150 ml works out around six dollars a month at a hazelnut twice a day, cheap for a fragrance-free foam with a declared botanical dose and an unusually good lather, and in line with pharmacy gel cleansers built on the same surfactant; the petals, the six hyaluronates and the botanical tail cost nothing and add nothing beyond charm. For oily and combination skin the value is good, and for dry or sensitive skin the same fifteen dollars buys the brand's centella or beta-glucan cleansers, which suit that skin far better.
Oily, combination and normal skin that wants a dense, unscented, thorough foam with a little charm in the tube at a low price, users of the brand's calendula cleansing oil who want its second-cleanse partner, and buyers who enjoy a visible botanical and understand that the foam, not the flower, is doing the cleaning.
Dry, sensitive, rosacea-prone, eczema-prone and barrier-impaired skin, for which the olefin sulfonate lead and the mugwort, bay and hinoki extracts are the wrong combination and the brand's gentler cleansers are the right one; anyone expecting the four acids to exfoliate or the six hyaluronates to hydrate in a rinse-off; and anyone sensitised to marigold.
Ready to try IUNIK Calendula Balancing Foam Gel Cleanser?
Buy at Amazon ♥A translucent, pale yellow gel flecked with calendula petals that works up in wet hands into a dense, creamy, high-volume foam, glides over the face and rinses completely to a clean, fresh, slightly matte finish with no squeak on normal skin.
Unscented; a faint, clean, herbal-green note from the botanical extracts in the lather, gone after rinsing.
A frosted, translucent 150 ml squeeze tube showing the yellow gel and petals, with a white flip cap, the IUNIK wordmark in gold and a yellow label reading Calendula Balancing Foam Gel Cleanser, Calendula Flower Extract, pH Balancing and All Skin Type; it stands on its cap and matches the brand's calendula cleansing oil.
The first wash is a surprise in the hand, a gel with petals in it that foams like a cream cleanser, dense and generous, and a rinse that leaves oily and combination skin fresh and matte without a squeak; dry skin notices the olefin sulfonate within a few days of twice-daily use as tightness, and reactive skin may feel the mugwort, bay or hinoki. There is nothing to adjust to, and the calendula is a colour and a faint herbal note rather than an event.
About two to three months at a hazelnut twice a day.
spring summer
IUNIK built its Calendula line on a cleansing oil and added this foam gel in June 2025 as its second-cleanse partner, sold as a double-cleansing duo, taking the whole-petal format that Korean calendula toners popularised into a foam; the brand's habit of long botanical tails and declared ppm figures is on full display, and the gel launched on the brand's US store at fifteen dollars for 150 ml.
IUNIK launched in 2017 as a Korean indie brand built on extract-heavy, minimal formulas with a following on r/AsianBeauty, and sells through its own US-facing store, Amazon, YesStyle and iHerb; its Calendula line pairs a cleansing oil with this June 2025 foam gel. The brand publishes full ingredient lists with ppm figures and no clinical testing, and this list carries the brand's typical long botanical tail.
Visible calendula petals make this a calming cleanser for sensitive skin.
The petals are a look, the extract is a declared three-quarters of a percent in a rinse-off, and the wash is built on sodium C14-16 olefin sulfonate, one of the stronger sulfate-free surfactants, with mugwort, bay and hinoki extracts in the tail; it is a good foam for oily and combination skin and a poor choice for reactive or eczema-prone faces, whatever the flower suggests. The brand's centella and beta-glucan cleansers are its gentle ones.
Salicylic acid, lactic acid and gluconolactone make this a pore-exfoliating cleanser.
The four acids sit at thirty-ninth to forty-ninth of fifty-three ingredients in a wash that is on the skin for under a minute; only the two salicylates have any route into a pore, and their contribution is a slight assist on the nose at most. The pore-balancing on the tube is the foam's thorough cleansing, and a leave-on BHA does the real work.
Not especially; it is fragrance-free and carries allantoin, panthenol and a declared three-quarters of a percent calendula, but its lead surfactant is sodium C14-16 olefin sulfonate, one of the stronger sulfate-free anionics, and its tail includes mugwort, bay and hinoki extracts. Oily and combination skin suits it; sensitive and dry faces do better with the brand's centella or beta-glucan cleansers.
The brand declares calendula flower extract at 7,396 ppm, about 0.74 percent, plus whole petals at 1,000 ppm suspended in the gel; that is a modest soothing note in a rinse-off and the source of the yellow colour and the flecks.
Only nominally: salicylic acid, capryloyl salicylic acid, lactic acid and gluconolactone sit at the tail of a fifty-three-ingredient list in a wash rinsed within a minute, and only the salicylates could reach a pore at all. It is a thorough foam rather than an exfoliating cleanser, and a leave-on BHA does the pore work.
Sunscreen and light makeup, yes, through its rich olefin sulfonate foam; a full face of long-wear makeup is better taken off with the brand's Calendula Complete Cleansing Oil first, which is how the brand sells the pair as a double-cleansing duo.
The calendula gel is the brand's rich-foaming oily-skin wash on an olefin sulfonate; the centella mild foam is a gentler syndet cream on isethionate and glycinate for normal and combination skin. Oily skin takes the calendula, and anyone who finds it tight takes the centella.
Fifteen dollars for a 150 ml tube on the brand's US store, cheap for a fragrance-free foam with a declared botanical dose; a hazelnut twice a day lasts two to three months.
