Etude Pore

Pore size is largely genetic - the diameter of a hair follicle is set by structure, not skincare. What makes pores appear larger or smaller is a combination of factors you can influence: sebum buildup that widens the pore opening from the inside, oxidation of that sebum that darkens it (creating blackheads), dead skin cells that accumulate at the surface and cast shadows into the pore, and reduced skin elasticity with age that lets pore walls loosen.

Skincare works on all four of these factors, but to different degrees. Deep cleansing and exfoliation address buildup; toners with astringent actives temporarily tighten pore openings; primers physically fill and blur pores before makeup. None of these permanently reduce pore diameter, but consistent use prevents the buildup that makes them look exaggerated.

The Baking Powder Pore Cleansing Foam is the most broadly stocked product in the ETUDE pore range on skinsli, available in both 160ml and 300ml sizes. The primary active is sodium bicarbonate (baking soda), which acts as a mild physical exfoliant. When combined with water and massaged onto the face, the slightly alkaline sodium bicarbonate helps dissolve sebum and surface debris.

The foam lathers densely, which makes it feel like a thorough cleanse. It is best suited to oily and combination skin types. People with dry or sensitive skin may find it too stripping for daily use; alternating it with a gentler cleanser every other day is a common approach in that case.

How to use it: Pump a small amount onto wet hands, lather between palms, then massage onto the face in circular motions for 30-60 seconds. Rinse thoroughly with lukewarm water. Avoid the eye area. If used morning and evening, monitor for signs of over-exfoliation such as tightness, shininess, or flaking, and reduce frequency if those appear.

The 300ml size is more economical for daily users; the 160ml is a practical travel or trial size.

The Baking Powder Crunch Pore Scrub is a rinse-off physical scrub with a coarser texture than the cleansing foam. It contains baking soda combined with a granular exfoliant that physically buffs dead skin cells from the surface. The product is available in 200g tubes and in a 7g × 24-pack single-use portion format.

Physical scrubs should be used with a light hand - the point is to roll the granules gently across the skin, not to press hard. One to two times per week is the standard recommendation for most skin types. Using a scrub more frequently, or pressing too firmly, causes micro-tears in the skin that increase sensitivity and can worsen the appearance of pores over time.

The single-use 7g × 24 pack is well suited to people who travel frequently or who want to keep the scrub hygienic between uses without reaching into a shared tube. Each sachet is a single application for the face and neck.

After scrubbing, follow with a toner such as the Wonder Pore Freshener to close pores and restore the skin's surface pH, which the alkaline baking soda will have temporarily raised.

The Wonder Pore Freshener is arguably ETUDE's most recognizable pore product. The 500ml bottle is considerably larger than standard Korean toners, designed for people who use it generously - either patting it in by hand or applying it with a cotton pad. The large size is part of the product's identity: ETUDE positioned it as a toner you should not have to ration.

The Freshener works primarily as an astringent toner. It contains niacinamide, witch hazel, and a blend of pore-minimizing actives that temporarily tighten pore openings and reduce the appearance of sebum on the skin surface. It also helps bring the skin's pH back toward the mild acid range (around 5.5) after alkaline cleansing, which supports the skin barrier.

Use it immediately after cleansing, before any serums or moisturizers. For oily skin, it can double as a between-session freshener during the day - kept on a desk or in a bag, a splash or cotton pad application at midday can reduce midday shine without disturbing makeup significantly.

The 500ml size means the product is not travel-sized as packaged, but decanting some into a smaller bottle for travel is straightforward.

The Sebum Soak Pore Primer is the finishing step in the ETUDE pore routine, applied after skincare and before makeup. It contains silica and pore-filling polymers that physically blur the appearance of enlarged pores and create a smooth surface for foundation or BB cream adhesion. The "sebum soak" name refers to the primer's secondary function: absorbent powders in the formula continue to soak up sebum throughout the day, extending the wear time of whatever makeup is applied on top.

Apply a small amount - about a pea size - across the T-zone and any other high-sebum areas after your skincare routine has fully absorbed. It should not be layered thickly; the primer works as a thin, even film. Allow 30-60 seconds before applying makeup on top. Using too much primer can cause pilling, particularly under liquid foundations.

For days with no makeup, some people use the primer on its own as a finishing step to control midday shine without adding coverage.

The ETUDE pore range is designed to work as a system, with each product targeting a different phase of pore care. A complete morning-to-evening routine using products from this collection might look like this:

• Evening cleanse: Baking Powder Pore Cleansing Foam (daily or alternate with a gentler cleanser)
• Weekly exfoliation: Baking Powder Crunch Pore Scrub, 1-2 times per week on evenings, used in place of the foam on those days
• Morning and evening toning: Wonder Pore Freshener 500ml, applied after every cleanse
• Morning pre-makeup: Sebum Soak Pore Primer, applied as the last skincare step before SPF and makeup

You do not need all four steps at once. Starting with the cleanser and the Freshener gives you the core cleansing-and-toning cycle. Adding the scrub once a week improves texture over time. The primer is most relevant on makeup days or when sebum control is a priority.

The ETUDE pore collection is built primarily for oily and combination skin types - the visible pore concern is most acute in these groups, and the Baking Powder cleansers, Wonder Pore Freshener, and sebum-absorbing primer are all calibrated for moderate-to-high oil production.

Oily skin: All products in the collection are appropriate. Daily use of the cleanser and Freshener, weekly scrub sessions, and daily primer use is a sustainable full-routine approach.

Combination skin: Focus the more active steps on the T-zone. Apply the primer selectively to the nose, chin, and forehead rather than full-face. The Wonder Pore Freshener is well-tolerated across combination skin types.

Dry or sensitive skin: The baking powder products may be too stripping for daily use. Use the Cleansing Foam two to three times per week rather than daily, and skip the Scrub or limit it to once a week. The Wonder Pore Freshener's astringent ingredients may cause tightness on very dry skin; test on a small area first.

Normal skin: The complete routine works well. Frequency can be reduced for each step compared to oily skin - the Scrub once a week, the Cleanser once daily, the Freshener after each cleanse.

The core ingredients across the collection reflect the pore-control focus:

• Sodium Bicarbonate (Baking Soda): Mild physical and chemical exfoliant. At a slightly alkaline pH, it helps break down sebum and dead skin cells. The primary active in the Cleansing Foam and Scrub.
• Niacinamide: Present in the Wonder Pore Freshener. Niacinamide (vitamin B3) has strong evidence for reducing the appearance of pores over time by regulating sebum production and strengthening the skin barrier. Effects are visible with consistent use over 4-8 weeks.
• Witch Hazel: An astringent plant extract that temporarily tightens pore openings and reduces surface shine. Common in pore-control toners.
• Silica and Pore-Filling Polymers: In the Sebum Soak Primer. These create a smooth physical surface by filling pore depressions, blurring their appearance optically. They also absorb sebum throughout the day.

The baking soda-based products will temporarily raise the skin's pH above its natural mild-acid state. Following with the Wonder Pore Freshener helps restore pH balance, which is why the toner is a logical step immediately after the baking powder cleanser or scrub.
