Pigmentation, dark spots and acne marks can make your complexion look uneven. A serum for pigmentation may seem like an obvious purchase, but not every product suits every skin type or routine. A high concentration, a striking claim or a well-known brand name alone says little about ease of use or tolerability.
The main pitfalls are usually:
A vitamin C serum is often chosen for dull skin and a more radiant appearance. Check which form of vitamin C has been used. The ingredients list may include 3-O-Ethyl Ascorbic Acid, Ascorbic Acid or a vitamin C derivative, for example. The concentration affects how the product should be used: according to the product information, Vitamin C23 contains 23% ascorbic acid, which is why the guidance recommends a patch test and cool storage.
A niacinamide serum is an alternative for anyone mainly looking to address an uneven complexion, visible pores or a weakened skin barrier. Check that the percentage is clearly stated. At 10% or above, it is sensible to introduce the product gradually, especially if you also use exfoliating products.
A serum for hyperpigmentation may contain AHA, such as lactic acid. According to the product description, AHA helps renew the skin’s surface, but it can make the skin more sensitive to sunlight. Therefore, use sunscreen during the day and always follow the warnings on the packaging.
Retinol is another active ingredient often found in an anti-ageing serum. The product is generally used in the evening and should be introduced gradually. Do not automatically combine retinol on the same evening with a high-dose vitamin C product, AHA or other strong exfoliants. If you are pregnant or breastfeeding, it is advisable to discuss using retinol with a healthcare professional first.
A serum that feels sticky or is heavily fragranced often ends up sitting unused. Check the ingredients list and product details. Also pay attention to:

Start with clean, dry skin and apply a small amount. When trying a new product, carry out a patch test on a small area of skin first. Do not introduce several new active products at the same time; this makes it easier to see which products your skin does or does not tolerate.
Use a sunscreen with suitable protection during the day, especially when using AHA, retinol or vitamin C. Stop using the product if you experience persistent redness, swelling, itching or a burning sensation. Do not apply the serum to damaged or irritated skin and avoid contact with the eyes. If you notice lasting or significant changes to your skin, seek advice from a doctor or dermatologist.
We have put together a complete, up-to-date list of products that fully meet these strict selection criteria and the applicable European safety regulations.
Look for a serum containing niacinamide, tranexamic acid or a vitamin C derivative. A serum for acne marks is not a direct solution for every type of discolouration. Choose one active product, introduce it gradually and use UV protection during the day.
This varies by formula. Check the jar, packaging and symbol indicating the shelf life after opening. For Vitamin C23, the product information states that it should be refrigerated and preferably used within two months of opening. Store other serums according to their specific label.
This can work in some routines, but there is no need to use all the active ingredients at once. For example, start with vitamin C or niacinamide in the morning and use retinol on separate evenings. Introduce new products gradually and stop if your skin becomes irritated.
