Choosing a good Korean face serum might seem straightforward, but the sheer range of options makes comparison tricky. A hydrating face serum, an azelaic acid serum and a vitamin C serum can look similar at first glance, yet each serves a very different purpose.
Marketing copy can also cause confusion. So pay close attention to the ingredients list, concentration, usage instructions and suitability for your skin type.
More ingredients don't automatically mean a serum is better for you. A sensitive skin can actually react to a formula packed with active ingredients, fragrances or plant extracts. First, look at the main goal: hydration, soothing, sebum control or a more even complexion.
Retinol, acids, vitamin C, azelaic acid and niacinamide can each have a place in a routine. If you use several potent products at the same time, your skin can feel dry or sensitive. Start with one new product and build up usage gradually.
According to a brand's own research, ingredients like centella asiatica, snail mucin or vitamin C can offer certain cosmetic benefits. That is not a guarantee for every skin type or every user. Product descriptions should therefore be read as information about the formula, not as a medical promise.
Choose the ingredient based on your skin goal:
A higher percentage is not automatically more practical. With retinol, building up slowly is important. The SOME BY MI Retinol Intense Trial Kit contains, according to the product description, 0.1% retinol and is designed to be started two to three evenings per week.
The SKIN1004 Azelaic Acid 10% Ampoule also requires a gradual introduction according to the usage instructions: use it every other day for the first week and then build up if desired.
A gel serum usually absorbs quickly and can be pleasant under sunscreen or make-up. A richer formula may be better suited to dry skin. Also pay attention to the volume: 30 ml is standard for a serum, while an ampoule of 55 or 100 ml can be more economical for daily use.
Store serums in a cool, dry place away from direct sunlight. Always check the expiry information and batch details on the packaging.
Why this suits the profile: A simple centella ampoule is an accessible starting point for anyone looking for a light, hydrating serum without a complicated mix of active ingredients.
The product description focuses on centella asiatica and hydration, so you don't have to combine several strong active ingredients straight away.
55 ml volume and a simple ampoule texture for daily use.
Why this suits the profile: This K-beauty serum is aimed at dry or tired-looking skin and combines, according to the product information, 3% snail mucin filtrate, ginseng, centella asiatica and hydrating ingredients.
The product details clearly state the formula and volume, so you can assess whether a gel texture and 30 ml fit your routine.
Ginseng, snail mucin filtrate, glycerine and hyaluronic acid in one gel serum.
Why this suits the profile: Ideal for anyone specifically looking for a serum for spots, visible redness or an uneven-looking complexion and wants to try azelaic acid for that purpose.
According to the product information, the formula is niacinamide-free and contains 10% azelaic acid. The instructions advise using it every other day during the first week.
10% azelaic acid, centella asiatica and a light serum texture; 30 ml volume.
Why this suits the profile: The set contains a serum and eye cream, each 10 ml. This makes getting to know retinol more manageable than buying a full-size product straight away.
The product instructions advise starting two to three times a week. This helps you avoid using retinol daily from the outset.
0.1% retinol, retinal, bakuchiol and peptides; practical trial set of 10 ml x 2.
Don't use several new products at the same time. This way, you can better assess which Korean skincare serum suits you.
We've put together a full, up-to-date list of products that fully meet these strict selection criteria and comply with current European safety regulations.
Look for a short ingredients list and soothing ingredients like centella asiatica, panthenol or glycerine. Use a serum for sensitive skin every other day at first. Avoid combining retinol, exfoliating acids and vitamin C from the start.
That depends on the volume, dosage and frequency of use. With two to three drops per application, 30 ml can last several weeks to a few months. Use the recommended amount and check the expiry information on the packaging.
It is possible in some routines, but for beginners it is simpler to use them at different times. For example, choose vitamin C in the morning and retinol in the evening. Build up both products separately and use sun protection during the day.
