A Korean skincare serum can be a targeted addition to your daily routine. However, it’s not wise to rely solely on terms such as “glow”, “glass skin” or “anti-ageing”. The formula, concentration, packaging and directions for use all play a much bigger part in whether a face serum is right for your skin.
A niacinamide serum with 10% or 15% sounds potent, but a higher concentration isn’t automatically more suitable. Sensitive skin may react more readily to several active ingredients at once. So check the full ingredients list rather than focusing only on the prominent percentage on the front of the packaging.
Using a serum for dark spots, a vitamin C serum, an exfoliant and a retinol alternative in the same routine can leave your skin unsettled. Instead, start with one main goal, such as hydration, a more even-looking complexion or a more comfortable skin barrier. Add a second active product later on.
Terms such as “stimulates collagen”, “repairs the skin” or “reduces wrinkles” often come from a brand’s product marketing. According to a brand’s own product description, this doesn’t automatically mean every skin type will experience the same results. Treat this information as a product promise, not a guaranteed outcome.
A formula with 2% alpha-arbutin, such as the one in the product information for Beauty of Joseon Glow Deep Serum, is easier to assess than a vague claim about “intense brightening”. With a vitamin C serum, it’s important to check which form is used, such as 3-O-ethyl ascorbic acid or ascorbic acid. Different forms can result in a different texture and feel.
Don’t combine strong active ingredients straight away. For example, use a retinal serum in the evening only, and gradually increase how often you use it. celimax’s product information recommends starting with alternate-day use and applying a small amount.
A dropper bottle needs to be used hygienically: don’t touch the pipette directly to your skin. Always check the expiry date and the period after opening on the packaging. Keep vitamin C and retinal products out of direct sunlight, and close the packaging securely.
Cosmetics sold in the EU should include, among other things, an ingredients list, contents, an expiry date or period after opening, and details of the responsible party. Check the packaging you receive, as label information can change. Stop using the product if irritation persists, and seek medical advice if you experience severe symptoms.

Why it suits this profile: This is a targeted evening option for users comparing a retinol alternative with retinal and who are prepared to follow a gradual introduction schedule.
The directions recommend starting on alternate days, using a small amount and applying it in the evening only. This makes the active formula easier to introduce gradually.

We’ve put together a complete, up-to-date list of products that meet these strict selection criteria and the applicable European safety requirements.
Look for a formula containing ingredients such as alpha-arbutin, niacinamide, tranexamic acid or vitamin C. A serum for dark spots doesn’t work in isolation from the rest of your routine: use sunscreen during the day and give the product enough time to work. Introduce only one new active serum at a time.
You can use them together in some routines, but it isn’t essential. Start with one product and see how your skin responds. If your skin is sensitive or prone to redness, you can use vitamin C and niacinamide at different times, for example one in the morning and one in the evening.
The exact shelf life is shown on the packaging. Also look for the period-after-opening symbol. Store the serum according to the manufacturer’s instructions, close it securely and keep it out of direct sunlight. If its smell, colour or texture changes, stop using it.
