A face serum can be a practical addition to your daily skincare routine. Its texture is usually lightweight, and serums often contain targeted ingredients such as niacinamide, hyaluronic acid, vitamin C or peptides. However, an expensive bottle is not automatically the right choice. Marketing claims also do not always indicate how well a formula will suit your skin.
A serum containing lots of active ingredients may seem appealing, but using several actives can make your routine unnecessarily complicated. For example, a vitamin C serum with niacinamide, tranexamic acid, alpha-arbutin and acids requires extra care when introducing it and monitoring how your skin reacts. So do not look only at the number of ingredients. Pay particular attention to:
Words such as “glow”, “firming” or “dark spot correcting” describe how a product is positioned, not a guaranteed outcome. A brand’s own research may suggest that certain ingredients can contribute to a visible effect, but this is not a fixed result for every user. Pigmentation, acne and fine lines can have different causes. A cosmetic serum is not a substitute for medical advice.
A retinol serum, retinal serum or highly concentrated niacinamide serum may not be suitable for immediate use twice a day. With active formulas, start with a small amount and use them infrequently. Stop if irritation persists and always check the product packaging.
Match the serum to one main need:
A percentage is only useful when you also assess the rest of the formula. For example, Anua lists 10% niacinamide and 4% tranexamic acid. According to its ingredients list, Beauty of Joseon Glow Deep Serum contains 2% alpha-arbutin. Dr. Althea Vitamin C Boosting Serum lists, among other ingredients, 3-O-ethyl ascorbic acid, ascorbic acid, niacinamide and sodium hyaluronate.
These are verifiable product specifications, but they do not predict exactly how your skin will react. As a rule, avoid combining several strong exfoliating or retinoid products without a clear reason.
A 20 or 30 ml dropper bottle is not the same as a 150 ml booster. Check:
Serum is usually applied after cleansing and, if desired, toner, followed by a moisturiser. During the day, vitamin C, retinal and retinol should be used alongside a sunscreen offering suitable protection.

A bakuchiol serum may be worth considering if you are looking for a formula without retinoids. However, “natural alternative” is still a brand claim, not a guarantee of an identical effect. For sensitive skin, a fragrance-free Centella ampoule or hyaluronic acid serum is generally easier to assess than a product containing several strong actives.
Usually after cleansing and before moisturiser. A watery serum can be applied before a richer cream. When using retinol or retinal, always follow the instructions on the packaging and preferably apply these formulas in the evening.
Check the expiry date and the symbol indicating the period after opening, such as 12M. Keep the bottle closed, somewhere cool and away from direct sunlight. Vitamin C, retinol and retinal products require extra care when it comes to storage and discolouration.
The price depends on the contents, brand, packaging and active ingredients. Compare the number of millilitres, recommended dosage and ingredients list. A 30 ml bottle may work out cheaper than a less expensive product that requires more per application.
