Choosing a face serum: how to compare ingredients, skin type and use without falling into marketing traps

A face serum can be a useful addition to your routine, but not every facial serum suits every skin type. A lightweight formula can feel comfortable on oily or combination skin, while dry skin often benefits more from glycerine, hyaluronic acid or other moisture-binding ingredients. If you focus mainly on eye-catching packaging or promises such as “glow”, you risk buying a product that does not meet your skin’s needs.

Three common pitfalls when choosing a face serum

1. Mistaking a long ingredients list for better performance

A serum containing lots of active ingredients may sound appealing, but more ingredients do not automatically mean it will suit your skin better. Niacinamide, vitamin C, tranexamic acid, retinol, peptides and exfoliating acids each serve a different purpose and may be less suitable for sensitive skin.

Always check the INCI label first. Look at which ingredients appear high up the list and bear in mind any known allergies. A brand’s product claims are no guarantee of the same results for every user. According to the brand’s product information, certain formulas may, for example, help create a smoother or more even-looking complexion; this is not a guaranteed personal result.

2. Accepting “for all skin types” without checking further

The description serum for all skin types is convenient, but says little about your specific situation. According to the product details, a formula may be suitable for all skin types and still feel less comfortable if your skin reacts quickly to alcohol, fragrance, retinol or a high concentration of active ingredients.

For dry skin, look for a hydrating serum containing glycerine, hyaluronic acid, panthenol or similar humectants. If your complexion looks dull, a brightening serum containing niacinamide, a vitamin C derivative or alpha-arbutin may be worth considering. For sensitive or blemish-prone skin, a short, straightforward routine is usually wiser than using several strong serums at once.

3. Expecting results too quickly

A serum for dark spots or an even-looking complexion does not work like an instant filter. Your skin’s visible appearance can also be affected by sleep, sun exposure, hydration and the rest of your routine. During the day, use sunscreen when advised on the label, particularly when using vitamin C derivatives, retinol, AHA or BHA.

Which specifications should you compare?

1. The active ingredient and concentration

Choose according to your main goal:

  • Hydration: look for hyaluronic acid, sodium hyaluronate, glycerine, beta-glucan or panthenol.
  • A brighter-looking complexion: a vitamin C serum, niacinamide serum or formula containing alpha-arbutin may be suitable.
  • Dark spots and an uneven complexion: compare niacinamide, tranexamic acid and alpha-arbutin in the ingredients list.
  • Fine lines and a firmer-looking complexion: look for peptides, adenosine or retinol. A brand’s product description may refer to an anti-ageing serum or firming serum, but focus primarily on the ingredients and directions for use.
  • Sensitive skin: ideally choose a fragrance-free formula and patch-test it on a small area of skin first.

Bear in mind that percentages are only meaningful when considered alongside the complete formula and frequency of use. A higher percentage is not automatically the better choice.

2. Skin type, texture and layering

A watery texture is often absorbed quickly and is easy to combine with a moisturiser. A gel serum can feel comfortable on normal, combination or blemish-prone skin. A richer formula may be better suited to dry skin, but can feel heavier under make-up.

Usually start with a cleanser, followed by toner if required, then serum and finally moisturiser. During the day, sun protection should be the last step. Introduce one new product at a time so that you can better assess how your skin reacts.

3. Size, shelf life and packaging

Do not compare the price alone; compare the amount as well. Many serums contain 20, 30, 50 or 100 ml. Check the period after opening, the expiry information on the packaging and the storage instructions. Vitamin C formulas and products containing retinol require extra care regarding light, heat and keeping the container properly closed.

A small bottle can make sense if you want to introduce an active ingredient gradually. A larger ampoule is more appealing when you use the product regularly and the formula suits your skin well.

Frequently asked questions about face serum

How do you use a facial serum?

Apply a few drops to cleansed skin, after toner if required. Gently spread the product over your face and neck, then finish with a moisturiser. Always follow the instructions on the packaging. When using an active ingredient, apply sunscreen during the day if recommended.

How long does a face serum last?

Shelf life varies from product to product. Check the expiry date and the period after opening on the packaging. Store the serum in a cool, dry place away from direct sunlight. Close the bottle securely after use, particularly when it contains vitamin C or retinol.

Can you use several serums at the same time?

Sometimes, but it is better to introduce products one at a time. Do not immediately combine several strong active ingredients. A hydrating serum containing glycerine or hyaluronic acid is generally easier to combine than multiple formulas containing retinol, acids or high concentrations of vitamin C. Stop using the product if irritation persists and follow the product’s safety information.
