Choosing a Korean facial serum: how to find a formula that suits your skin

A Korean facial serum can be a targeted step in your routine, but attractive packaging and terms such as “glass skin” say little about whether it is suitable for your skin. The right choice depends mainly on your skin concern, the ingredients list and how easily you can fit the product into your daily skincare routine.

As a consumer in the Netherlands, watch out for three common pitfalls:

  • A long ingredients list is not automatically better. A serum containing lots of active ingredients can be difficult to combine with other products.
  • A high percentage is no guarantee of better results. Your skin’s tolerance, the formula and the usage instructions also play a part.
  • Marketing claims are sometimes interpreted too broadly. “Repairing”, “anti-ageing” or “regenerating” does not always describe a proven effect. Always check the official product information and the full INCI list.

Which specifications should you check?

1. Choose your primary skin concern first

A serum is easiest to assess when you choose one main objective. Consider the following:

  • Dry skin: a hydrating serum with glycerine, panthenol, beta-glucan or hyaluronic acid.
  • Dull skin or uneven complexion: look for niacinamide, alpha-arbutin, tranexamic acid or vitamin C derivatives.
  • Sensitive skin: choose a serum for sensitive skin with a short ingredients list and soothing ingredients such as centella asiatica, panthenol or allantoin.
  • Blemish-prone skin or visible redness: azelaic acid may be an interesting cosmetic option. Start gently and stop if irritation persists.
  • Wanting a firmer-looking complexion: a peptide serum, bakuchiol serum or anti-ageing serum may fit into your skincare routine. Claims about firmness and fine lines should be understood as cosmetic product claims, not medical guarantees.

2. Check the active ingredients and their concentration

An ingredient’s name does not tell the whole story. According to the product information, for example, Beauty Of Joseon Glow Deep Serum contains 2% alpha-arbutin, niacinamide and rice bran water. This makes it suitable for anyone mainly looking for a more even, radiant-looking complexion and hydration.

With a hyaluronic acid serum, it is useful to check whether several forms of hyaluronic acid have been used and whether the formula also contains moisture-retaining ingredients. According to the product description, Torriden DIVE IN combines five types of hyaluronic acid with panthenol, ceramide NP and beta-glucan.

A vitamin C formula requires extra care with storage and daytime use. Dr. Althea Vitamin C Boosting Serum contains, among other ingredients, 3-O-ethyl ascorbic acid, niacinamide, tranexamic acid and alpha-arbutin. According to the product information, daily use of sun protection is recommended.

3. Consider the packaging, frequency of use and skin tolerance

A dropper does not automatically prevent contamination. Avoid touching your skin with the dropper. A pump bottle can be practical for everyday use, as with the Beauty of Joseon Revive Serum.

With concentrated formulas, it is wise to build up use gradually. According to the usage instructions, Anua Azelaic Acid 10 Hyaluron Redness Soothing Serum recommends starting with one or two drops, once or twice a week. According to the packaging, products containing azelaic acid may cause a tingling sensation or dryness.

Also check:

  • the full INCI list on the packaging;
  • the expiry date and period after opening;
  • whether it contains fragrance or known allergens;
  • warnings relating to the eyes, damaged skin and sun exposure;
  • whether the texture suits your routine: gel, lotion or a slightly richer ampoule.

Test a new serum on a small area of skin first. If you experience redness, swelling, itching or persistent irritation, stop using it. Cosmetics are intended for external use and are not a substitute for advice from a doctor or dermatologist.

How to use a K-beauty serum in the Netherlands

Apply a serum after cleansing and, if desired, toner, but before your moisturiser. Usually, one to a few drops are enough. Dry skin benefits from applying moisturiser over the serum, helping to lock in the moisture you have applied.

During the day, use a broad-spectrum sunscreen if your routine contains ingredients that may increase sensitivity or if the packaging recommends it. Preferably, do not introduce several new actives at once. For example, start with a hydrating serum and only add vitamin C, azelaic acid or a peptide serum later.

Frequently asked questions about a Korean facial serum

How long does a facial serum last?

This depends on the volume, dosage and frequency of use. A 30 ml bottle will usually last less time with daily use than a 50 or 100 ml bottle. Always check the expiry information on the packaging and close a dropper or pump bottle securely.

Which serum is suitable for sensitive skin?

Choose a formula with a limited number of active ingredients and look out for fragrance, alcohol and potential allergens. Centella asiatica, panthenol, beta-glucan and hyaluronic acid are used in various product formulas for hydration and skincare. Always test each new product on a small area of skin first.

Can I use vitamin C and azelaic acid together?

Some skin types can tolerate this, but the combination may be unnecessarily intense if both ingredients are new to you. Start with one product, use it according to the packaging and build up gradually. If irritation occurs, reduce the frequency or stop using the product.
