Choosing Korean face serums: a practical guide for every skin type

Korean face serums cater to a wide range of skin needs, from dryness and a weakened skin barrier to visible pigmentation, redness and a dull complexion. But an attractive label doesn’t guarantee that a serum will fit into your routine. Three common pitfalls in particular can lead you to spend money on a product you barely use.

Three common pitfalls with K-beauty serums

1. Mistaking a long ingredient list for a better formula
A serum with dozens of ingredients might sound appealing, but more isn’t automatically better suited to your skin. If you have sensitive skin, a shorter formula containing ingredients such as panthenol, beta-glucan or hyaluronic acid may be easier to assess. Also check whether it contains fragrance, alcohol or exfoliating ingredients.

2. Treating marketing claims as guaranteed results
Words such as “restorative”, “lifting” or “collagen-boosting” often come from the brand’s product marketing. A brand’s own research may link these claims to certain results, but that’s no guarantee for every user. Start by looking at information you can verify, such as the ingredients, concentration, size and directions for use.

3. Combining too many active ingredients at once
Using a niacinamide serum, an azelaic acid serum, a retinol product and an exfoliant in one routine can make things unnecessarily complicated. Start with one goal and build up gradually. If you experience irritation, burning, itching or swelling, stop using the product and follow the instructions on the packaging.

What to look for in a Korean face serum

1. Choose ingredients to suit your skin goals

The most important factor isn’t where the serum comes from, but whether its ingredients suit your skin type and routine.

  • Dry skin or a weakened skin barrier: look for glycerin, panthenol, beta-glucan, ceramide NP and hyaluronic acid. A hydrating serum such as a hyaluronic acid serum helps draw in moisture; seal it in with a moisturiser.
  • Dull complexion or visible pigmentation: alpha-arbutin, niacinamide, tranexamic acid and certain vitamin C derivatives are often found in serums for pigmentation. Use sun protection during the day.
  • Redness or sensitive skin: look for panthenol, centella asiatica, allantoin, beta-glucan or azelaic acid. A serum for redness is not a substitute for medical treatment. Patch test it on a small area of skin first.
  • Signs of skin ageing: peptides, adenosine and bakuchiol are used in anti-ageing serums. Brands claim that these ingredients may help give skin a smoother or firmer appearance; individual results vary.
  • PDRN serum: check that PDRN or sodium DNA actually appears in the ingredients list. The term alone tells you nothing about the concentration or results.

2. Check the concentrations and full ingredients list

A percentage gives you more context than a striking claim on the front of the packaging. For example, Beauty Of Joseon Glow Deep Serum lists 2% alpha-arbutin and 68.6% rice bran water. ANUA Azelaic Acid lists 10% azelaic acid. Its directions recommend starting with one or two applications a week.

Also look out for potential points to consider:

  • Retinol: Medicube PDRN Pink Exosome Shot Serum contains retinol according to its listed ingredients. The product information warns that this may increase sensitivity to sunlight; use sun protection during the day and follow the label.
  • Fragrance: ANUA 7 Rice Ceramide Hydrating Barrier Serum and Medicube PDRN Pink Peptide Serum list fragrance. That doesn’t have to be a problem, but it’s useful to know if you have sensitive skin.
  • Alcohol: some formulas, such as Medicube PDRN Pink Exosome Shot Serum and Medicube Triple Collagen Serum 4.0, list alcohol or alcohol denat. Check whether this suits your skin.
  • Formulas may change: ingredients can change over time. When your product arrives, always compare the packaging with the online product information.

3. Consider the size, texture and how you’ll use it

A 20, 30, 50, 100 or 150 ml serum can last for very different lengths of time. A few drops per application make a small bottle a good way to try a product first, while a 150 ml booster can be handy for everyday use.

Also consider the texture:

  • A watery booster often layers well with other skincare products.
  • A gel serum, such as Beauty of Joseon Revive Serum, can feel comfortable on dry or normal skin.
  • A richer formula with oils or silicones may feel comfortable, but may not be the best fit if you prefer a very lightweight routine.

Store Korean face serums in a cool, dry place away from direct sunlight, and close the packaging after use. Check the expiry or PAO information on the label.

Frequently asked questions about Korean face serums

How do you use a Korean face serum?

First, cleanse your face and use toner if you wish. Then apply a few drops of serum and gently pat it in. Finish with a moisturiser. Use sun protection during the day, especially with products containing retinol, azelaic acid or ingredients intended to even out your skin tone.

How long does a bottle of serum last?

It depends on the size and how much you use. At two to three drops per application, 30 ml may last from several weeks to a few months. Always follow the recommended amount and check the expiry information on the packaging. Don’t store the serum in direct sunlight.

Which serum is suitable for sensitive skin?

Start by looking for a simple formula without fragrance or known irritants. Ingredients such as panthenol, beta-glucan, ceramide NP and hyaluronic acid are often chosen for hydration and comfort. Patch test any new serum for sensitive skin on a small area, and don’t introduce several new active products at the same time.
