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

A face serum can be a targeted addition to your daily skincare routine. Its lightweight formula often contains a higher concentration of certain ingredients than a standard cream. However, an expensive serum is not automatically right for your skin. The best choice depends on your skin type, your main skincare goal and how you introduce active ingredients.

Common pitfalls when choosing a face serum

1. Confusing marketing claims with guaranteed results

Words such as “radiant”, “repairing” and “anti-ageing” sound appealing, but mean little without specific information about the formula. So check the ingredients list and product details. Look out, for example, for niacinamide, hyaluronic acid, azelaic acid, retinol or peptides.

Claims about visible results come from brands or sellers. A brand’s own research may report certain outcomes after a specific period of use, but this is not a guarantee for every user.

2. Using too many active ingredients at once

Combining a serum for dark spots with a retinol serum, exfoliant and strong vitamin C product can make your routine unnecessarily complicated. Sensitive skin in particular may react to several new products being introduced at the same time.

Start with one new face serum and use it according to the label. Gradually increase the frequency when recommended. A patch test on a small area of skin can help you assess tolerance in advance.

3. Skipping SPF when targeting pigmentation or fine lines

A serum for a more even complexion does not change your daily exposure to UV rays. Use a suitable sunscreen during the day, especially when using a retinol serum, acids or a serum for dark spots. Always check the specific safety warnings on the packaging.

Which features should you compare?

1. Choose your main skincare goal

Use this practical guide:

  • Dry or tight-feeling skin: look for a hydrating serum containing glycerine, panthenol, ceramides or a hyaluronic acid serum.
  • Dull skin or an uneven complexion: look for niacinamide, vitamin C derivatives, alpha-arbutin or tranexamic acid.
  • Dark spots: compare the concentration and combination of ingredients. A formula containing niacinamide, azeloglycine, tranexamic acid or alpha-arbutin may suit this goal.
  • Fine lines and wrinkles: an anti-ageing serum may contain peptides, hyaluronic acid or retinol. Retinol requires gradual introduction and extra care with sun protection.
  • Blemish-prone skin: a serum for acne or oily skin sometimes contains niacinamide, salicylic acid or azelaic acid. These ingredients may help reduce shine in some routines, but are not a substitute for medical advice.
  • Sensitive or redness-prone skin: choose a serum for sensitive skin with a short, easy-to-understand ingredients list, and avoid introducing new fragrances or several acids at once.

2. Check concentrations and usage restrictions

A higher percentage is not always more practical. SKIN D-PIGMENT SERUM ATX B3, for example, lists 10% niacinamide, 3% azeloglycine and 2% tranexamic acid. The product information also mentions 0.45% lactic acid for hydration. According to the brand’s own research, a reduction in melanin and the visibility of dark spots was reported after two months. Treat this as brand information, not a guaranteed result.

With retinol, the instructions for use are particularly important. ROC capsules recommend starting every other day. Medicube products containing retinol warn of increased sensitivity to sunlight and recommend using sunscreen every day. Also check restrictions relating to pregnancy, breastfeeding and irritated skin.

3. Consider texture, fragrance and size

A serum that feels sticky often ends up unused. A watery formula works well under a moisturiser, while an oil-based or richer texture may feel more comfortable on dry skin. Also check the volume: a 20, 30, 50 or 100 ml container makes a difference to the price per millilitre.

Fragrance-free options are available, but not every product is fragrance-free. The product information for Torriden DIVE IN, for example, states that it has a fragrance-free formula, while some other serums contain perfume or fragrance ingredients. If your skin reacts easily, it is best to check the full ingredients list on the packaging.

How to use a face serum in practice

Apply a serum usually after cleansing and, if desired, toner, but before your moisturiser. Use a few drops and gently press the product into your skin. Follow the label if the serum is intended for evening use only.

Do not combine several strong formulas straight away. For example, if you want to try a niacinamide serum, first see how your skin responds before adding an exfoliant. With a retinol serum, gradual introduction is important. During the day, use a sunscreen with an appropriate SPF.

Frequently asked questions about face serums

How long does a face serum last?

The shelf life is shown on the packaging either as a date or as a period after opening, such as 12M. Keep the serum tightly closed, out of direct sunlight and according to the manufacturer’s storage instructions. A change in smell, colour or texture may be a reason to stop using the product.

Can I use a serum every day?

That depends on the ingredients. A hydrating serum containing hyaluronic acid is often described for morning and evening use. A retinol serum or formula containing acids may require a gradual introduction schedule instead. Always follow the product instructions and stop using it if irritation persists.

Which serum is suitable for sensitive skin?

Look for a straightforward formula, test it on a small area of skin first and avoid introducing several new active ingredients at once. Also check the ingredients list for fragrance, alcohol, acids and retinol. If you have severe or persistent skin concerns, advice from a doctor or dermatologist is more appropriate than continuing to switch between serums.
