A face serum can be a targeted addition to your daily skincare routine. However, it is not wise to rely solely on words such as “glow”, “intensive” or “instant results”. The right choice depends mainly on your skin type, the ingredients list and how often you want to use the product.
If you are looking for a Korean face serum, you will often see lots of similar packaging and promises. Below, you can read which pitfalls to avoid, which specifications matter and which products suit different uses.
A serum containing 10% azelaic acid, niacinamide or another active ingredient may be appealing for a specific routine. However, a higher percentage may also be less suitable for someone with sensitive skin or a damaged skin barrier. With active formulas, start by using the product infrequently and follow the instructions on the packaging.
A product may be described as suitable for all skin types, yet still contain fragrance, alcohol or several active ingredients. Always check the full ingredients list. When choosing a serum for sensitive skin, for example, look out for fragrance, essential oils and ingredients that have caused you to react in the past.
Combining a hydrating serum with a niacinamide serum is usually straightforward, but using several exfoliating or retinoid products at once makes it harder to identify the cause of irritation. It is better to introduce one new product at a time. This makes it easier to see how your skin responds to the formula.
First, choose the main goal of your routine:
Check whether the brand states a percentage. The SKIN1004 Azelaic Acid Ampoule, for example, lists 10% azelaic acid. According to the usage instructions, it is best to start by using it every other day. ANUA recommends starting its azelaic acid serum with one or two drops, once or twice a week, and gradually increasing use.
Gradual introduction is even more important with retinal. According to the product description, the celimax THE VITA-A RETINAL SHOT contains 0.1% pure retinal. The brand recommends using it every other evening during the first two weeks. Do not use retinal on irritated or damaged skin, and apply sun cream the following morning.
A watery gel generally absorbs quickly and works well under a day cream or sun cream. A richer serum containing oils or ceramides may feel more comfortable on dry skin. Also consider the size:
When choosing vitamin C serums, also check the storage advice. Close the packaging securely and keep the product out of direct sunlight.

Do not use several new active serums on the same day. If you experience redness, itching, swelling or a burning sensation, stop using the product. Consult a doctor or pharmacist if skin complaints persist.
This depends on the formula. According to the product instructions, a hydrating serum can often be used in the morning and evening. It is better to introduce an azelaic acid serum or retinal serum gradually. Always check the brand’s label and warnings.
Yes. The usual order is cleanser, toner, serum, moisturiser and sun cream during the day. Allow each layer to absorb briefly if the products start to pill.
Follow the expiry date and the period-after-opening guidance on the packaging. Store the product somewhere cool and out of direct sunlight. Vitamin C, retinal and other active ingredients may particularly benefit from secure packaging and careful storage.
