Korean skincare for acne and enlarged pores: how to choose the right products

Spots, blackheads, a shiny T-zone and visible pores don’t automatically call for an elaborate ten-step routine. When choosing Korean skincare for acne and enlarged pores, focus on a gentle routine, suitable active ingredients and a schedule your skin can tolerate.

Common mistakes when buying acne skincare

1. Using too many active ingredients at once

AHA, BHA, PHA, salicylic acid, niacinamide and azelaic acid often appear in Korean skincare. That doesn’t mean you need them all straight away. Combining different exfoliants can leave your skin dry, tight or sensitive.

It’s better to start with one targeted product. For example, use a salicylic acid cleanser or a BHA product a few times a week, then see how your skin responds.

2. Mistaking a tight feeling for a thorough cleanse

A cleanser that leaves your skin feeling tight may remove more than just oil and dirt; it could also leave your skin feeling uncomfortable. For skincare for sensitive skin, a gentle face wash with a skin-friendly pH is often a sensible starting point.

Check the full ingredients list. A product may be described as gentle, but still contain fragrance, essential oils or ingredients you’re sensitive to.

3. Taking pore-related marketing claims at face value

Pores can’t be permanently “removed”. Products can, however, help make them look less visible by reducing excess oil, dirt and dead skin cells. Always read claims such as “clinically proven” in context. A brand’s own research may measure certain results under specific conditions; that’s no guarantee of the same results for everyone.

Which specifications matter?

Cleansing: gentle or active?

For daily use, look for mild surfactants, glycerine and a pH of around 5 to 6. The SKIN1004 Madagascar Centella Ampoule Foam, for example, lists a pH of 5 and is formulated for daily use. The Dr. Althea Green Relief Amino Gel Cleanser lists a mildly acidic pH of 5.0–6.0 and amino acid- and coconut-based cleansers.

If your main concern is excess oil and blackheads, look for salicylic acid. The COSRX Salicylic Acid Daily Gentle Cleanser lists 0.5% salicylic acid. Tea tree oil and citrus oil are also on the ingredients list, so a patch test is sensible if you have sensitive skin.

Active ingredients and concentrations

  • Niacinamide: the celimax serum formula lists 5% niacinamide. It may suit anyone looking to address the appearance of pores, uneven skin tone and oiliness with one serum.
  • Azelaic acid: the Anua formula lists 10% azelaic acid, alongside panthenol, ceramides and hyaluronic acid. Start slowly, following the product instructions — for example, once or twice a week.
  • BHA: according to the product information, COSRX BHA Blackhead Power Liquid contains betaine salicylate. This type of exfoliant is often chosen for blackheads and oilier skin.
  • AHA/BHA/PHA: these acids help loosen dead skin cells, but can make your skin more sensitive to the sun. Use sun protection during the day and don’t combine several exfoliating products straight away.

How to use products and choose for your skin type

An effective routine doesn’t need to be complicated:

  1. Cleanse with lukewarm water and a small amount of cleanser.
  2. Use no more than one active serum or exfoliant per routine.
  3. Apply a moisturiser.
  4. Use sun protection during the day.
  5. Test new products on a small area of skin first.

If your acne is persistent, painful or widespread, speak to your GP or a dermatologist rather than adding more and more cosmetic products.

Frequently asked questions

Which Korean skincare products help with blackheads?

Look for a product containing BHA or salicylic acid, such as a salicylic acid cleanser or a liquid exfoliant. Start by using it sparingly, and don’t combine it straight away with AHA, PHA or a strong active serum.

How often should I replace acne patches?

Follow the instructions on the packaging. For the Cosrx Acne Pimple Master Patch, it says to replace the patch when it looks white and full. Apply patches to clean, dry skin.

Can I use niacinamide and azelaic acid together?

Sometimes, but it’s best to introduce new products one at a time. Use small amounts, build up gradually and stop if you experience persistent redness, itching or a burning sensation. Always check the latest ingredients list on the packaging.
