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

A face serum usually contains a concentrated formula and is applied before your moisturiser. This makes it appealing if you want to give extra attention to hydration, an uneven complexion, fine lines or sensitive skin. At the same time, the wide range of options can be confusing. A high price, eye-catching packaging or promising claim does not automatically mean that a serum is right for your skin.

Joybuy Product Recommendation Officer helps you filter the most important information from marketing copy. Pay particular attention to the ingredients list, directions for use and suitability for your skin type.

Common mistakes when buying a face serum

1. Mistaking a long ingredients list for a powerful formula

A product with dozens of ingredients is not necessarily more effective. First, look at the active ingredients that match your goal:

  • Hyaluronic acid and glycerine are often used in hydrating serums.
  • Niacinamide is found in formulas aimed at a more even-looking complexion and supporting the skin barrier.
  • Retinol is used in anti-ageing serums and wrinkle serums, but should be introduced gradually.
  • Alpha-arbutin, tranexamic acid and vitamin C derivatives are found in products for brightening care or serums for pigmentation.
  • Panthenol, beta-glucan, centella asiatica and ceramides are relevant ingredients when you are looking for a serum for sensitive skin.

Always check the current INCI list on the packaging. Formulas can change.

2. Treating brand claims as guaranteed results

Words such as “repairs”, “makes wrinkles invisible” or “penetrates deeply” are marketing phrases. A brand may report certain visible results based on its own research, but such claims do not automatically apply to every user.

A cosmetic serum cares for the skin. It is not a substitute for medical treatment. If you experience persistent irritation, significant redness or other skin concerns, it is advisable to seek professional advice.

3. Using an active serum without building up gradually

A retinol serum, azelaic acid serum or formula containing exfoliating ingredients may cause sensitivity for some users. Start with a small amount and use it infrequently at first. Test a new product on a small area of skin before applying it more widely, and follow the label.

Use a sun protection product during the day when recommended in the product information. This is especially relevant for routines targeting pigmentation and those involving retinol.

Important features to compare

Skin type and texture

Dry or mature skin may benefit from a serum containing glycerine, hyaluronic acid, squalane, oils or ceramides. A lightweight gel texture often feels more comfortable on combination or oilier skin. If you are looking for a Korean skincare serum, you will often find lightweight, watery formulas containing ingredients such as niacinamide, centella asiatica and beta-glucan.

Also check for fragrance and alcohol. A fragrance-free product may be a sensible choice for sensitive skin, but “fragrance-free” does not guarantee that irritation is impossible. Therefore, check the full ingredients list.

Active ingredient and time of use

Choose one main concern as your starting point. A hyaluronic acid serum, for example, may suit tight-feeling and dehydrated skin. For an uneven complexion, you could look for niacinamide, alpha-arbutin or vitamin C derivatives. A retinol serum is generally used in the evening and should be introduced gradually.

Combining more active ingredients is not always necessary. A simple routine of cleansing, serum, moisturiser and daytime sun protection is often easier to manage than using several intensive products at once.

Size, packaging and shelf life

Do not compare only the price; consider the volume too. A 10.5 ml capsule product is used differently from a 50 or 100 ml bottle. A pump bottle can make dispensing easier, while a pipette requires hygienic use without touching the dropper directly to your skin.

Check the shelf life, batch information and period after opening on the packaging. Store the serum according to the label, preferably somewhere cool and away from direct sunlight. Stop using it if you experience an unwanted reaction.

How to use a face serum in your routine

  1. Cleanse your face and gently pat the skin dry.
  2. Apply a small amount of serum, usually a few drops or the amount stated on the label.
  3. Use the product after toner if that suits your routine.
  4. Apply moisturiser afterwards.
  5. Use sun protection during the day when recommended, especially as part of a routine with retinol or ingredients for a more even complexion.

Do not combine several new active serums at the same time. This makes it easier to see which product suits your skin and reduces the risk of unnecessary irritation.

Frequently asked questions about face serums

Which serum is suitable for dry skin?

Look for a hydrating serum containing glycerine, hyaluronic acid, panthenol, beta-glucan or ceramides. Apply moisturiser afterwards to help support the skin’s comfort. An oily or richer texture may feel pleasant if a watery gel does not provide enough comfort.

Can I use a retinol serum every day?

Not straight away. Follow the label and preferably start by using it every other day or less often, depending on the product instructions. Retinol is generally used in the evening, and you should pay attention to sun protection during the day. Stop if irritation occurs and check the safety information.

How long does a face serum last?

This varies by product. Check the expiry date, batch information and the period-after-opening symbol on the packaging. Close the bottle securely and store the serum according to the instructions. A change in smell, colour or texture may be a reason to stop using the product.
