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. However, sometimes you are paying mainly for eye-catching packaging, a long ingredients list or promises that are not clearly substantiated. The right choice therefore starts not with the name “anti-ageing serum” or “Korean face serum”, but with your skin type, the result you want and the product information.

Common pitfalls when choosing a face serum

1. A long ingredients list does not tell you everything

A serum containing lots of plant extracts or active ingredients may look appealing, but more ingredients do not automatically mean it will suit your skin better. Focus on which ingredients are relevant to your goal. For hydration, you will often see glycerine, hyaluronic acid and panthenol. With a retinol serum, the concentration, directions for use and warnings are more important than a long list of supporting extracts.

2. Marketing claims are sometimes taken too literally

Terms such as “repairs”, “lifts”, “stimulates collagen” or “reduces wrinkles” regularly appear in product descriptions. A brand may mention such results based on its own research or marketing communications, but they are not guaranteed for every user. Consider a firming serum or anti-wrinkle serum as cosmetic skincare that may support the appearance of the skin, rather than as a medical treatment.

3. Texture and size are often underestimated

A 7 ml, 9 ml or 15 ml serum may be suitable as a targeted treatment, but it will run out sooner than a 30, 50 or 100 ml bottle. Texture also makes a difference. A lightweight face ampoule may feel comfortable under sun cream, while a richer serum for dry skin may be better suited to your evening routine. So compare the price per 10 ml, not just the price of the pack.

Which specifications should you check?

Skin type and main goal

Start by choosing one main goal. A hydrating serum containing hyaluronic acid may be suitable if your skin feels tight or dry, for example. A formula with niacinamide or rice extract may appeal if you are looking for a more even-looking complexion. For sensitive skin, a short ingredients list, a fragrance-free formula and introducing the product gradually are practical considerations.

Bear in mind that “suitable for all skin types” is a general product description. Individual tolerance can vary. Test a new face serum on a small area of skin first and stop using it if irritation persists.

Active ingredients and combinations

  • Hyaluronic acid: often used to help retain moisture and leave the skin feeling supple.
  • Niacinamide: found in formulas designed to support hydration and a more even-looking complexion.
  • Vitamin C: often used in a vitamin C serum to give the complexion a brighter appearance. Products containing acids or fragrance may feel less comfortable for some users.
  • Retinol and retinal: vitamin A derivatives. These products are generally used in the evening, introduced gradually and accompanied by daytime sun protection. Always follow the label.
  • Centella Asiatica: a commonly used ingredient in serums for sensitive skin and Korean ampoules. According to the product description, it is often chosen to provide a comfortable, soothing feel on the skin.

Packaging, size and how to use it

A pump bottle limits direct contact with the formula and can be practical for everyday use. A pipette gives you more control over the amount, but it is best not to touch the skin directly with it. Also check the shelf-life information, the period after opening and the storage advice on the packaging.

Apply a serum to cleansed skin, usually before moisturiser. Do not combine several strong active products straight away. This makes it easier to assess how your skin reacts to one new formula.

Frequently asked questions about face serum

How do you use a face serum?

First cleanse your face, then apply a few drops or one or two pumps. Gently spread the serum over your face and, if desired, your neck. Finish with a moisturiser. Use sun protection during the day, especially when using a retinol serum or a formula containing exfoliating ingredients.

How long does a serum last?

This depends on the size and how much you use. A 30 ml bottle will generally last longer with daily use than a 9 ml ampoule, but actual usage varies from person to person. Store the product according to the label, close the packaging securely and check the shelf-life information.

Which serum is suitable for dry or sensitive skin?

A hydrating serum containing glycerine, hyaluronic acid or panthenol is a logical starting point. If you have sensitive skin, avoid introducing several strong active ingredients at once. A fragrance-free option can make comparing products easier, but always check the full ingredients list yourself and stop using the product if irritation occurs.
