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

A face serum can be a useful addition to your daily skincare routine. Its lightweight formula often contains a higher concentration of specific ingredients than a standard cream. However, a long ingredients list does not automatically mean that a serum is right for your skin.

Many consumers pay too much for a product that does not meet their skin’s needs. The right choice therefore starts not with an eye-catching claim on the packaging, but with the formula, how it is used and your skin’s tolerance.

Common pitfalls when choosing a face serum

1. Mistaking an impressive claim for a guaranteed result

Words such as “lifting”, “glow” and “collagen boost” sound appealing, but they do not always clearly describe what you can expect from the product. According to a brand’s own research, for example, a formula may improve the appearance of firmness or smoothness. That is a brand claim, not a guarantee for every skin type.

Look out for verifiable information:

  • Which active ingredients are listed?
  • Is the concentration stated, such as 10% niacinamide or 4% tranexamic acid?
  • Is the serum intended for the face, the eye contour or the scalp?
  • Are there clear warnings about use and combining it with other products?

2. Using too many active ingredients at once

An anti-ageing serum, niacinamide serum, vitamin C formula and peptide serum can each serve a different purpose. However, introducing several potent products at the same time makes it difficult to determine which product is causing irritation.

Start with one face serum. Use it for several weeks according to the instructions on the packaging, and only then consider adding a second formula. If you have sensitive skin, a patch test is advisable.

3. Choosing a serum without considering the texture

A hydrating serum with glycerine, hyaluronic acid or panthenol usually feels lightweight. A formula containing oils, silicones or richer emollients may feel more comfortable on dry skin, but less suitable under sun cream or make-up.

Also consider the packaging. A pump bottle helps reduce waste. A dropper bottle often gives you more control over the amount, while a spray or precision applicator may be intended for a specific area of use.

Which specifications are important?

1. Start by identifying your main skin concern

Use the following guide as a practical starting point:

  • Dehydrated skin: look for glycerine, hyaluronic acid, betaine, panthenol or ceramides. These are suitable for a hydrating serum.
  • Dull or uneven complexion: niacinamide, tranexamic acid, arbutin and vitamin C derivatives are often found in a serum for radiant skin or a serum for pigmentation.
  • Fine lines and loss of firmness: peptides, adenosine and collagen extracts are often used in a firming serum, collagen serum or peptide serum.
  • Dark circles: choose a product developed specifically for the eye contour, such as an eye serum for dark circles. Do not automatically use a face serum directly around the eyes.
  • Sensitive skin: look out for fragrance, alcohol, retinol and exfoliating acids. A short ingredients list and introducing the product gradually may be more practical.

2. Check both concentrations and position in the ingredients list

A percentage is useful, but it is not the only criterion. Ingredients are generally listed in descending order by quantity, with exceptions for low concentrations and certain supporting ingredients.

For example, Medicube TXA NIACINAMIDE 15 SERUM states 15% niacinamide and tranexamic acid. ANUA NIACINAMIDE 10% + TXA 4% SERUM states 10% niacinamide and 4% tranexamic acid. This makes comparison easier than when packaging only refers to a “brightening complex”.

Bear in mind that brand descriptions about reducing pigmentation are cosmetic claims. Do not consider them a medical treatment. Wear sun cream during the day when working towards a more even-looking complexion.

3. Pay attention to warnings and combinations

Some products contain retinol or micro-spicules. Medicube PDRN Pink Peptide Eye Serum contains retinol; the product information recommends, among other things, a patch test and daily SPF 30 or higher during the day. The same product is not recommended for people who are pregnant or breastfeeding.

VT COSMETICS Collagen Reedle Shot 100 contains CICA REEDLE and may cause a tingling sensation according to the product information. Do not use it on damaged or irritated skin, immediately after dermatological treatments or together with a beauty device. Always check the packaging, as ingredients and usage instructions may change.

How to use a face serum in practice

  1. Cleanse your face and gently pat the skin dry.
  2. Apply a small amount of serum. Using more product does not automatically produce better results.
  3. Avoid the eye contour unless the product is specifically intended for that area.
  4. Finish with a moisturiser to help retain moisture.
  5. Wear sun cream during the day, especially when using formulas containing retinol, vitamin C derivatives or ingredients that may make the skin more sensitive.
  6. Stop using the product if you experience persistent redness, itching, swelling or a burning sensation, and consult a doctor or dermatologist if necessary.

A Korean skincare serum is often designed to be used in several thin layers. However, a simple routine is usually easier to manage: cleanse, apply one face serum, moisturiser and SPF during the day.

Frequently asked questions about face serum

When should you apply face serum?

Use serum after cleansing and, if applicable, after toner, but before your moisturiser. Follow the specific instructions on the packaging. A lightweight formula usually works well under cream and sun cream.

How long does serum last?

Check the expiry date and the period after opening stated on the packaging. Some products, for example, indicate 6M or 12M after opening. Store the serum in a cool, dry place away from direct sunlight. Close the bottle securely after use to keep the formula as stable as possible.

Can you combine several serums?

Sometimes, but introduce new products one at a time. Do not combine retinol, acids, micro-spicules and potent brightening ingredients without careful consideration. If in doubt, a simple routine with one serum and a moisturiser is a safe way to start.
