Choosing Korean skincare: a practical guide for every skincare routine

Korean skincare is popular for its lightweight textures, layering approach and ingredients such as niacinamide, Centella asiatica and hyaluronic acid. However, a long ingredients list does not guarantee that a product will suit your skin. Buying a toner, several Korean serums and a retinol serum without a plan can mean spending money on products that overlap or leave your skin unsettled.

Pay particular attention to these three common pitfalls:

• Confusing marketing claims with guaranteed results. A brand may talk about a “glow”, an even complexion or anti-ageing benefits, for example. Treat this as a claim made by the brand, not a guaranteed result.
• Using too many active ingredients at once. Retinol, vitamin C, AHA, BHA and niacinamide can all have a place in Korean facial skincare, but combining them is not always practical for beginners.
• Relying solely on your skin type. A product for oily skin can still feel drying. Also check the texture, fragrances, acids and directions for use.

Which specifications deserve attention?

1. Look at the active ingredient and its concentration

A facial serum can only be compared properly when it is clear which ingredients it contains and, where stated, in what quantity. Examples include:

• Niacinamide serum: suitable for anyone looking for a lightweight, watery formula that supports a more even-looking complexion.
• Brightening serum or serum for dark spots: look for ingredients such as alpha-arbutin, tranexamic acid, vitamin C derivatives and niacinamide.
• Retinol serum: start with a low frequency of use, such as two or three evenings a week. Use sun protection during the day. The SOME BY MI Retinol Intense Trial Kit contains 0.1% retinol according to the product description and is fragrance-free.
• Hydrating skincare: glycerine, panthenol, sodium hyaluronate, ceramides and Centella asiatica are often found in formulas designed to leave skin feeling comfortable.

According to a brand’s own research, a formula may, for example, help with fine lines, redness or pigmentation. Read such statements as brand communications. Always check the ingredients, warnings and directions for use on the packaging.

2. Check the formula for potential sensitivities

For skincare for sensitive skin, a short ingredients list is not automatically enough. Pay attention to:

• perfume, essential oils and fragrances such as linalool and limonene;
• retinol, AHA, BHA and high concentrations of vitamin C;
• alcohol, if your skin reacts sensitively to it;
• storage instructions and the shelf life after opening.

A patch test on a small area of skin is advisable when trying a new active product. Stop using it if irritation persists and consult a doctor or other healthcare professional if you experience symptoms. Cosmetics are not a treatment for a medical skin condition.

3. Choose the right order and amount

A simple routine helps you avoid unnecessary purchases:

1. Cleanse with a gentle cleanser, such as a facial cleanser that does not leave your skin feeling tight.
2. Use toner or essence if you enjoy extra hydration.
3. Apply one serum that matches your main concern.
4. Finish with a cream.
5. In the morning, use sun protection according to the instructions on the product.

An essence such as SK-II Facial Treatment Essence is a liquid step between cleansing and the rest of your routine. The product description states that it contains more than 90% PITERA; check the current packaging and ingredients list before buying. If you would rather try several steps first, you could also consider a set containing cleanser, lotion, essence and cream.

Frequently asked questions about Korean skincare

What is a simple Korean skincare routine?

Start with cleanser, followed if desired by toner or essence, one serum, a moisturiser and sun protection during the day. Introduce active ingredients step by step. This makes it easier to see which product feels comfortable and which formula may cause irritation.

How long does a serum or essence last?

That depends on the size and how often you use it. A 30 ml serum will generally run out sooner with daily use than a 100 ml ampoule. Always check the expiry date, batch information and period after opening on the packaging. Vitamin C products may have additional storage instructions; COSRX Vitamin C23, for example, states that it should be refrigerated and used within two months of opening according to the product information.

Can you use retinol, vitamin C and niacinamide together?

Niacinamide is often combined with other ingredients, but retinol, high concentrations of vitamin C, AHA and BHA require greater care. If necessary, use strong active products at different times and introduce them gradually. Follow the official directions for use, carry out a patch test and use sun protection during the day.
