A face serum can be a useful addition to your routine, but a high concentration or striking claim does not automatically mean the product is right for your skin. If you focus only on terms such as “glow”, “deep repair” or “glass skin”, you could end up with a serum that feels sticky, causes irritation or remains unused in your bathroom.
With this practical guide, you can assess ingredients, when to use the product, your skin type and the available product information. This makes it easier to compare a hydrating serum, anti-ageing serum, hyaluronic acid serum or Korean skincare serum based on verifiable features.
A product containing, for example, 10% Matrixyl or 2% alpha-arbutin may seem easy to compare, but the percentage does not tell you everything. The rest of the formula, its texture and the condition of your skin also affect how comfortable the serum is to use.
Product claims about fine lines, elasticity, pigmentation or skin renewal are not a guarantee of the same result for every user. A brand’s own research may report certain visible effects, but these results are not automatically universal.
Combining a retinol product with several exfoliating or highly concentrated serums can make your skin feel uncomfortable. Start with one new product instead. Use it according to the label and gradually build up the frequency, especially when using a serum for sensitive skin.
A serum may contain glycerine, hyaluronic acid, panthenol or beta-glucan, giving your skin a comfortable feel. That does not automatically mean the formula meets all the needs of a dry skin barrier. Applying a moisturiser after your serum helps your skin retain moisture more effectively.
Always check the complete INCI list. Product pages may change; the packaging remains the definitive source.
A lightweight, watery serum often works well under a moisturiser and sun cream. A richer facial ampoule may feel more comfortable on tight-feeling skin, but may be less comfortable under make-up. Only use a night serum in the evening if this is stated on the packaging.
Apply a face serum after cleansing and, if desired, toner, followed by a moisturiser. Wear sun cream during the day when advised in the product information, particularly with products containing retinoid-like ingredients.
Choose products that clearly state:
A cosmetic product should not make medical claims. Claims such as “restores the skin” or “reduces wrinkles” should therefore be read as product communication, not as a guaranteed or medical effect.

We have put together a complete, up-to-date list of products that fully meet these strict selection criteria and the applicable European safety regulations.
Use the serum after cleansing and, if desired, after toner, but before moisturiser. Two to three drops are often enough. Always follow the specific directions for use. When using a retinol serum or concentrated ampoule, it is sensible to build up use gradually.
Check the expiry date or the open-jar symbol showing the period after opening on the packaging. Close the bottle after use, store it in a cool, dry place and do not leave it in direct sunlight for extended periods. Has the smell, colour or texture changed? Stop using the product.
No. The price may reflect the brand, packaging, contents and formula, but it is not proof of better personal results. Compare the INCI list, contents per millilitre, directions for use and suitability for your skin type. If irritation persists, stop using the product and seek advice from a doctor or dermatologist.
