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

There are Korean face serums for almost every skin concern, from a hyaluronic acid serum for dryness to a niacinamide serum for an uneven skin tone. The wide choice is useful, but it can also make comparing products more difficult. Eye-catching packaging or a long ingredients list doesn’t automatically mean a serum is right for your skin.

The most common purchasing mistakes are:

• Assuming a higher percentage means a better choice. 10% niacinamide or 23% vitamin C may sound impressive, but a high concentration may be less suitable for sensitive skin.
• Using too many active ingredients at once. Using a vitamin C serum, retinol serum and exfoliating product in the same routine can cause irritation more quickly.
• Looking only at marketing claims. Terms such as “glow”, “repair” and “anti-ageing” don’t always tell you exactly what’s in the formula. So check the ingredients, size and directions for use.

Which properties should you check?

1. Choose one main goal first

Decide which concern you want to address first. Common ingredients for hydration include glycerine, panthenol, beta-glucan, ceramides and hyaluronic acid. A hydrating serum is especially practical when your skin feels tight or flaky.

For dull skin or visible discolouration, you could look for niacinamide, alpha-arbutin, tranexamic acid or vitamin C. A serum for dark spots won’t clear discolouration in one go; consistent use and daily sun protection are still important.

For redness or skin that reacts easily, simple formulas containing ingredients such as centella asiatica, panthenol, allantoin or green tea are often easier to assess. A serum for redness isn’t a medical treatment. If your symptoms persist, it’s wiser to seek advice from a GP or dermatologist.

2. Consider the concentration and directions for use

A percentage is only useful when you know how to use the product. According to the product information, Vitamin C23 contains 23% ascorbic acid. The advice is to carry out a patch test, store it in a cool place and use it within two months of opening. This makes it more suitable for experienced users than for someone just starting out.

According to the ingredients list, Some By Mi Retinol Intense Reactivating Serum contains 0.1% retinol, as well as retinal. The directions recommend building up use gradually, applying the product in the evening and using sun protection during the day. Don’t combine retinol with other strong active ingredients without careful consideration.

3. Check the full ingredients list

Don’t just look at the ingredient on the front of the pack. Check the following too:

• Fragrance: worth considering if you prefer to avoid fragrance or have sensitive skin.
• Alcohol: not all types of alcohol work in the same way, but its presence may matter to some users.
• Texture: a gel, essence or oil-based formula will feel different under sunscreen or make-up.
• Size: 30 ml is common, while a booster such as The 6 Peptide Skin Booster contains 150 ml.
• Shelf life after opening: always follow the packaging. For example, the product information for Beauty of Joseon Light On Serum states that it should be used within six months of opening.

Some By Mi Retinol Intense Reactivating Serum 30 mL

Why it suits this profile: This is a targeted choice for people who are already familiar with retinol. The formula lists 0.1% retinol, retinal, bakuchiol, panthenol and ceramide NP.

How this product avoids the pitfall

The product information includes a gradual build-up schedule, recommends evening use and advises carrying out a patch test. This makes it clear that an active serum shouldn’t automatically be used every day from the very first day.

Key benefit & highlights

Lists 0.1% retinol and retinal; contains panthenol and ceramide NP; clear directions for gradual adjustment.

How to build a simple routine

Start by cleansing, then apply toner if you use one, followed by one serum. Finish with a moisturiser. Use sun protection during the day, especially if you use a vitamin C serum, retinol serum, azelaic acid serum or serum for dark spots.

Want to combine several serums? Test each product separately first. For example, use a hydrating serum in the morning and an active serum in the evening. If redness, itching, swelling or a burning sensation persists, stop using the product and check the safety information on the packaging.

Frequently asked questions about Korean face serums

Which serum is suitable for sensitive skin?

Look for a short ingredients list without fragrance and choose soothing or hydrating ingredients such as panthenol, glycerine, centella asiatica and ceramide. Always carry out a patch test first. A product description saying “suitable for sensitive skin” doesn’t guarantee that everyone will tolerate the product.

How long can you use a serum for?

It depends on the formula. Check the expiry date on the packaging and the period after opening. Store vitamin C and retinol products according to the relevant advice, for example away from direct sunlight or in the fridge if specifically instructed.

Can you combine niacinamide, hyaluronic acid and vitamin C?

This may work in some routines, but don’t introduce everything at once. Hyaluronic acid is mainly hydrating, while niacinamide and vitamin C are active ingredients with different usage profiles. Start with one new serum and only add a second product later if your skin remains calm.
