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

A face serum can be a useful step between cleansing and moisturising. Its texture is usually lighter than a cream, and formulas often focus on one main goal, such as hydration, a more even-looking complexion or firmer-feeling skin. Even so, it is not advisable to rely solely on terms such as “glow”, “lifting” or “anti-ageing”.

The product description, ingredients list and instructions for use provide more useful guidance. Below, you’ll find what to look out for and which popular choices suit different skin types and routines.

Common pitfalls when choosing a face serum

1. A long ingredients list does not tell you everything

A serum containing dozens of ingredients may seem comprehensive, but more ingredients do not automatically mean it is a better fit for your skin. First, look for ingredients that match your goal:

  • Glycerin, panthenol and hyaluronic acid are often used in hydrating serums.
  • Niacinamide is found in formulas designed to promote a more even-looking complexion and support the skin barrier.
  • Peptides are popular in firming serums and peptide serums.
  • Retinol or retinal is used in serums for skin renewal and signs of skin ageing.

An ingredient’s position in the INCI list can indicate its approximate amount, but it does not state exactly how much has been added. So, also pay attention to the product information and warnings.

2. Marketing claims are sometimes interpreted as guarantees

Terms such as “reduces wrinkles”, “stimulates collagen” or “repairs the skin” are not a personal guarantee. A brand’s own research may report certain results, but those outcomes do not automatically apply to every user. In this article, we therefore treat such statements as product claims rather than established effects.

A wrinkle serum is also not a substitute for medical treatment. If you experience persistent irritation, a skin condition or uncertainty about active ingredients, it is sensible to seek advice from a doctor or pharmacist.

3. The wrong texture can make daily use difficult

An oil serum may feel comfortable on mature or dry skin, while a watery gel may be better suited to someone who does not want to feel much product on their skin. A serum that is too rich under make-up may pill. A serum that is too light may not provide enough comfort in winter without a moisturiser.

As well as the ingredients, check the formula, volume and recommended frequency of use.

Key points to consider when comparing products

Start by choosing your skin goal

For a serum for dry skin, humectants and soothing ingredients are useful factors to consider. A hyaluronic acid serum, for example, often contains sodium hyaluronate or different forms of hyaluronic acid. Always follow this with a moisturiser to complete your routine.

If your main concerns are fine lines and a less firm-looking complexion, you could consider an anti-ageing serum, peptide serum or firming serum. Pay attention to the combination of ingredients, but do not expect an immediate or guaranteed change.

Check active ingredients and warnings

Retinol and retinal are vitamin A derivatives. Products containing these ingredients often require gradual introduction, evening use and daily sun protection. Some products also state that they should not be used during pregnancy or breastfeeding without advice from a healthcare professional.

Apply new formulas to a small area first. Stop using the product if you experience redness, a burning sensation, itching or swelling. Do not simply combine several active serums in one routine, especially if your skin reacts sensitively.

Consider the contents, packaging and origin information

When comparing 15, 30, 50 or 100 ml, do not look only at the price. Also consider how much product you use each time. A pump bottle can be practical and limit contact with the formula. Check the packaging for:

  • the complete INCI list;
  • expiry or period-after-opening information;
  • warnings and instructions for use;
  • the manufacturer and EU responsible person;
  • the presence of fragrance, alcohol or other ingredients to which you may be sensitive.

Cosmetics sold in the EU must comply with the applicable cosmetic regulations. Check the specific product information yourself, as the formulation and packaging may change.

Frequently asked questions about face serum

How often should you use a face serum?

It depends on the formula. A hydrating serum is often used in the morning and evening. With retinol or retinal, it is better to start with a low frequency according to the label, such as a few evenings per week. Only increase the frequency if your skin tolerates it well.

How long does a bottle of serum last?

A 30 ml bottle can last from several weeks to several months with daily use. This depends on the dosage, the type of pump and whether you use the serum only on your face or also on your neck and décolletage. Store the product in a cool, dry place away from direct sunlight.

Can you use several serums at the same time?

Sometimes, but combine active ingredients carefully. A hydrating serum containing hyaluronic acid will often work well alongside another product. It is better not to layer retinol, exfoliating acids and highly concentrated formulas without preparation. Always check the instructions and introduce new combinations gradually.
