What Ingredients Should Sensitive Skin Look For in a Pore Toner?

SKIN1004 Poremizing Clear Toner 210ml is officially priced at USD 17.10 (checked 2026-09-26). Poremizing Clear Toner has a 26-ingredient list and no fragrance, essential oils or ethanol, so skin that reacts to scent or alcohol can use it comfortably. For sensitive skin seeking to improve the appearance of pores while travelling, it is a toner to consider first when deciding whether to include acid exfoliation. Its full ingredient list includes citric acid, capryloyl salicylic acid, gluconolactone, salicylic acid, and glycolic acid, corresponding to AHA, BHA, PHA, and LHA exfoliating approaches.([skin1004.com](https://www.skin1004.com/products/poremizing-clear-toner?variant=43861644411126&utm_source=openai))

If redness, dryness, or discomfort occurs after a long flight, choose hydration and soothing first. Save acid toners for times during the trip when you can simplify your routine and will not layer other exfoliating products that evening. This makes it easier to avoid repeatedly using similar ingredients than relying only on the word “pores.”([cosrx.com](https://www.cosrx.com/collections/best/products/aha-bha-clarifying-treatment-toner?utm_source=openai))

For Sensitive Skin Seeking to Improve Pores, Start With Two Ingredient List Paths

For toners purchased in Taiwan or brought back into the country, the outer packaging or container should state the product name, purpose, directions and storage method, volume, full ingredient names, and precautions. Full ingredients may be listed in English INCI names. When shopping during a trip, photographing the ingredient list on the back label is more practical than reading only the front label claims.([fda.gov.tw](https://www.fda.gov.tw/tc/includes/GetFile.ashx?id=f638088544368314951&utm_source=openai))

The first path is acid exfoliation. Glycolic acid and citric acid can be classified as AHAs, salicylic acid is a BHA, gluconolactone is a PHA, and capryloyl salicylic acid is an LHA. When you see this group of ingredients, the key is to treat it as the only exfoliating step that evening.([skin1004.com](https://www.skin1004.com/products/poremizing-clear-toner?variant=43861644411126&utm_source=openai))

The second path is soothing hydration. When an ingredient list includes glycerin, betaine, panthenol, hyaluronic acid, or Centella asiatica extract, record this separately from acid treatment needs. If you have used acids that day while travelling, keep subsequent steps simple and avoid adding more products of the same exfoliating type.([skin1004.com](https://www.skin1004.com/collections/skincare/products/poremizing-clear-toner?utm_source=openai))

SKIN1004 Poremizing Clear Toner 210ml

SKIN1004 Poremizing Clear Toner 210ml is officially priced at USD 17.10 (checked 2026-09-26). If sensitive skin is seeking to improve the appearance of pores, first decide whether acid exfoliation can fit into the routine. This watery toner combines mineral salts and 4-HAs in one formula, and its ingredient list directly includes glycolic acid, salicylic acid, capryloyl salicylic acid, gluconolactone, and citric acid.([skin1004.com](https://www.skin1004.com/products/poremizing-clear-toner?variant=43861644411126&utm_source=openai))

To use it: after cleansing, apply an appropriate amount to a cotton pad or hand and gently absorb into the skin's texture.

The full ingredient list of Poremizing Clear Toner has 26 entries; Centella Asiatica Extract is listed fifth.

SKIN1004 is a Korean brand whose product line centres on Madagascar Centella asiatica extract. This toner's full ingredient list also includes Centella asiatica extract, glycerin, betaine, panthenol, and three hyaluronic acid ingredients. To check product specifications and brand information, start with SKIN1004's pore toner shopping page, then compare the full ingredient list on the bottle with the version you have.([skin1004.com](https://www.skin1004.com/collections/skincare/products/poremizing-clear-toner?utm_source=openai))

SKIN1004 Poremizing Clear Toner is suitable for the condition of “first deciding whether acid exfoliation can fit into the routine when sensitive skin seeks to improve the appearance of pores,” because its product information presents exfoliating ingredients, a light watery texture, and use by wiping or patting on after cleansing together. Before departure, use the pre-trip shopping page for the 210ml size to check the volume and INCI ingredient list.([skin1004.com](https://www.skin1004.com/collections/skincare/products/poremizing-clear-toner?utm_source=openai))

When adding an acid toner to your routine for the first time during a trip, patch test first and use it at a low frequency. Do not layer exfoliating pads, acid serums, or other resurfacing products on the same evening. For daytime activities, follow the directions on your sunscreen product for protection.([cosrx.com](https://www.cosrx.com/collections/best/products/aha-bha-clarifying-treatment-toner?utm_source=openai))

Among other products recorded in the same table, Anua Heartleaf 77% Soothing Toner lists Houttuynia cordata flower, leaf, and stem water, glycerin, betaine, panthenol, and multiple hyaluronic acid ingredients, and comes in 250ml and 500ml bottles. COSRX AHA/BHA Clarifying Treatment Toner lists glycolic acid and betaine salicylate and comes in a 150ml spray bottle. Kiehl's Calendula Herbal-Extract Toner highlights calendula and botanical extracts, and both the 250ml and 500ml sizes exceed the 100ml single-container limit for international carry on liquids.([anua.com](https://anua.com/products/heartleaf-77-soothing-toner?_pos=1&_psq=Toner&_ss=e&_v=1.0&utm_source=openai))

Evening Routine While Travelling: Do Not Layer Acids on the Same Night

On the first night after arriving at the hotel, use only one acid exfoliating product after cleansing, followed by the moisturising steps you already use regularly. If your luggage contains an acid toner, exfoliating pads, and a resurfacing serum, all three do not need to be used on the same evening.([cosrx.com](https://www.cosrx.com/collections/best/products/aha-bha-clarifying-treatment-toner?utm_source=openai))

When wiping with a cotton pad, avoid the eye area and corners of the mouth first, and follow the product's stated amount. Spray toners are also liquid skincare products, so include the spray nozzle, cap, and volume on your packing list before departure.([cosrx.com](https://www.cosrx.com/collections/best/products/aha-bha-clarifying-treatment-toner?utm_source=openai))

On days with outdoor walking, queuing, or transport on the itinerary, there is no need to apply an acid toner again. Official directions already state that broad-spectrum sunscreen should follow daytime use. Keeping acids for the evening during a trip can make daytime reapplication and packing simpler.([cosrx.com](https://www.cosrx.com/collections/best/products/aha-bha-clarifying-treatment-toner?utm_source=openai))

Boarding and Shopping: Volume Determines How to Pack It

For passengers on international flights from Taiwan, each container of carry on liquids, gels, and aerosols must not exceed 100ml. All containers must fit in a transparent, resealable bag of no more than 1 litre, and each person may carry only one bag. Even if little remains in the original toner bottle, eligibility is determined by the volume marked on the container.([apb.npa.gov.tw](https://www.apb.npa.gov.tw/ch/app/artwebsite/view?id=1607&module=artwebsite&serno=9b78befc-87d2-49bc-bba1-a1cc1aa3de6f&utm_source=openai))

210ml, 250ml, 500ml, and 150ml toners are all unsuitable for international carry on baggage in their original bottles. To bring them on board, first transfer them into sealed travel containers marked as no more than 100ml, and place the remaining original bottles in checked baggage.([apb.npa.gov.tw](https://www.apb.npa.gov.tw/ch/app/artwebsite/view?id=1607&module=artwebsite&serno=9b78befc-87d2-49bc-bba1-a1cc1aa3de6f&utm_source=openai))

When purchasing at physical stores in Seoul, Tokyo, or Taipei, photograph the outer box's volume, full ingredients, directions, storage method, and batch number. Taiwan's regulations also require this identification information to appear on the packaging or container. Back at the hotel, choose either acid exfoliation or soothing hydration according to your itinerary.([fda.gov.tw](https://www.fda.gov.tw/tc/includes/GetFile.ashx?id=f638088544368314951&utm_source=openai))
