Choosing a face serum: how to compare ingredients, skin type and usage

A face serum can be a practical addition to your daily skincare routine. Its lightweight texture often contains concentrated ingredients and can be applied under a cream or sun protection. However, not every serum is suitable for every purpose. If you focus only on terms such as “intensive”, “revolutionary” or “anti-ageing”, you can quickly end up paying for a formula that does not suit your skin.

Common pitfalls when choosing a face serum

1. Mistaking a long ingredients list for a better formula

A serum containing lots of active ingredients may seem appealing, but several powerful ingredients can also be difficult to combine. Retinol, retinal, vitamin C, niacinamide and acids each have their own usage guidance. For beginners, choosing one clear goal is often wiser than selecting a product that promises to do everything at once.

Also pay attention to where an ingredient appears in the ingredients list. The order gives an indication of the quantity, but it does not tell you everything about the formula’s eventual performance or stability.

2. Taking brand claims at face value

Claims about less visible wrinkles, reduced pigmentation or younger-looking skin do not guarantee the same result for every user. According to NIVEA’s own research, for example, certain users may notice a difference in hydration or fine lines after the stated period. Such results depend on the test design, duration of use and condition of the skin.

Instead, focus mainly on verifiable information: the type of active ingredient, its concentration if stated, the volume, the intended area of application and the safety instructions.

3. Overlooking SPF and the adjustment period

A vitamin C serum or hydrating serum can be a good fit for a morning routine, but it does not replace sunscreen. Extra care is needed with retinol and retinal. These vitamin A derivatives can increase sensitivity to sunlight. Introduce them gradually and always follow the instructions on the packaging.

Important specifications to check

Purpose and active ingredients

First, choose your main skincare goal:

  • Hydration: look for glycerine, hyaluronic acid, panthenol and ceramides. A hydrating serum is particularly suitable if your skin feels tight or dry.
  • Dull and uneven complexion: vitamin C, niacinamide and certain vitamin C derivatives are often found in a vitamin C serum.
  • Fine lines and skin texture: retinol or retinal may suit a targeted evening routine. These ingredients require gradual introduction.
  • Pigmentation: look for ingredients such as azelaic acid, niacinamide or tranexamic acid. A serum for pigmentation cannot work independently of daily sun protection.
  • Sensitive or weakened skin barrier: choose a simple formula with soothing and moisture-binding ingredients. At first, avoid combining several strong actives.

An anti-ageing serum, wrinkle serum and face serum are not separate legal product categories. They are primarily commercial descriptions. So check what is actually in the bottle.

Concentration, volume and shelf life

A percentage is only useful when you know which ingredient it refers to. For example, Neostrata states 0.3% pure retinol, while some other products do not list a concentration on the product page. Therefore, compare not only percentages, but also the formula and usage instructions.

Look out for:

  • volume in millilitres;
  • shelf life and the PAO symbol, for example 12M;
  • a pump or dropper dispenser that limits exposure to air and light as much as possible;
  • storage instructions, particularly for retinol, retinal and vitamin C;
  • allergens, fragrance and alcohol if your skin is sensitive to them.

Cosmetics sold in the EU are covered by European cosmetics regulations, including Regulation (EC) No 1223/2009. Nevertheless, always check the ingredients, warnings and manufacturer details on the packaging. A product labelled “dermatologically tested” is not automatically problem-free for every skin type.

Texture and where it fits in your routine

Apply a serum after cleansing and, if applicable, toner, but before moisturiser. During the day, apply sun protection as the final step. When trying a new serum, start with a small amount and test it first on a small area of skin.

An eye serum is designed for the area around the eyes. This does not mean that every face serum is suitable for use there too. Avoid direct contact with the eyes and follow the manufacturer’s specific advice.

How to use a serum without making your routine unnecessarily complicated

  1. Cleanse your face and gently pat the skin dry.
  2. Apply one to a few drops of serum, depending on the product instructions.
  3. Follow with a moisturiser to help lock in moisture.
  4. Apply a broad-spectrum sunscreen during the day.
  5. Introduce only one new active product at a time, so you can identify any reaction more easily.

Preferably use a retinol serum or retinal serum in the evening. According to the warnings on several of the products mentioned, products containing retinoids are not suitable during pregnancy or breastfeeding. If redness, itching or a burning sensation persists, stop using the product and seek medical advice.

Frequently asked questions about face serum

How long does a face serum last?

This depends on the volume, dosage and frequency of use. A 30 ml bottle can last from several weeks to several months when used daily. Check the shelf life after opening and store the serum according to the label, away from direct sunlight and tightly closed.

Can I use several serums at the same time?

Sometimes, but it is better to start with one serum. Do not combine retinol or retinal with other strong actives without careful consideration. A hydrating serum containing glycerine or hyaluronic acid is generally easier to combine, but always check the full ingredients list and directions for use.

Which serum is suitable for sensitive skin?

Choose a short, straightforward formula with hydrating and soothing ingredients. Introduce the product gradually and carry out a patch test beforehand. Avoid trying a new retinol serum or vitamin C serum when your skin is already irritated.
