Best Korean Serum: Which One Suits Your Skin?

"Which Korean serum is the best?" – the honest answer: the one whose active matches your skin concern. A vitamin C serum for dark spots does nothing for red, sensitive skin. A centella serum soothes, but does not make dull skin more radiant. So instead of a ranking, here is a guide: 20 Korean serums and ampoules from our range, sorted by what your skin needs right now.

What a Korean serum is – and what an ampoule is

A serum is the active step of the Korean routine. It comes after cleansing and toner and before the cream, has a light, watery to gel-like texture, and delivers one clearly named main active in a higher concentration: vitamin C, niacinamide, centella, hyaluronic acid, collagen, PDRN, peptides, bakuchiol, or mild acids. An ampoule is essentially the same thing, usually a bit more concentrated and often intended as a course of treatment. In use, the two do not differ: two to three drops, pat in gently, cream on top.

For dull skin and dark spots: vitamin C and niacinamide

#OOTD Dark Spot Vitamin C Serum

Dark spots, an uneven skin tone, and dull-looking skin? The Dark Spot Serum works with 1 % vitamin C and Vitamin Tree Water for more brightness and glow, without a sticky skin feel. The low concentration makes it a beginner serum, also for sensitive skin. Pat a pea-sized amount onto the affected areas after cleansing. Vegan.

Dearboo Brightening Vita C Hyaluronic Intensive Serum

For combination and oily skin with dark spots: the stable vitamin C derivative 3-O-ethyl ascorbic acid reduces dark spots, refines pores, and regulates sebum. Sea buckthorn extract with omega-7 and vitamin E provides antioxidant protection, while hydrolyzed collagen and hyaluronic acid plump up fine lines. The light texture absorbs without a film. Morning and evening after the toner, and always with sunscreen during the day.

PURITO Pure Vitamin C Serum

The stronger option with pure ascorbic acid: the Pure Vitamin C Serum visibly brightens the complexion, reduces dark spots, and supports collagen production. The light texture absorbs quickly. For normal, combination, and oily skin. Two to three drops after the toner, then moisturizer and sunscreen during the day. Vegan.

APLB Glutathione Niacinamide Ampoule Serum

When the skin looks tired and lackluster: glutathione and niacinamide support a more even complexion and a fresh glow, while the formula provides intense hydration at the same time. The light texture is suitable for layering and for daily care morning and evening. For all skin types, including dry skin. Vegan.

Anua Peach 70% Niacin Serum

Dull complexion and pores that look larger? 70 % peach extract and niacinamide provide hydration and support a fresher, more even look, while three types of hyaluronic acid plump up the skin. The watery texture works under makeup. For all skin types. Two to three drops on face and neck, avoid the eye area, and always finish with SPF in the morning. Vegan.

For sensitive skin with redness: centella and green tea

SKIN1004 Madagascar Centella Ampoule

The classic with only seven ingredients: a high proportion of Centella Asiatica from Madagascar soothes redness and irritation, and the hydrating formula absorbs quickly and leaves no sticky film. Hypoallergenic and low in irritants, for sensitive and dry skin. Two to three drops morning and evening, can be combined with any other care. Vegan.

PURITO Wonder Releaf Centella Serum Unscented

If your skin also reacts to fragrances: the Wonder Releaf Serum contains 49 % centella extract, niacinamide, ceramide NP, hyaluronic acid, and peptides, entirely without perfume. It provides hydration, reduces redness, and strengthens the skin barrier. The light texture is not sticky. For all skin types, especially sensitive skin. Vegan.

Beauty of Joseon Calming Serum: Green Tea + Panthenol

Redness and tightness after a long day? 50 % green tea, 30 % mugwort, and 5 % panthenol support the skin barrier, provide hydration, and make redness look calmer. Light, not sticky, also under makeup. For very sensitive skin, use once a day at first and increase as needed.

For blemish-prone skin and pores: acids, salt, and propolis

Dearboo Skin Balancing Centella Cica Serum

Impurities, pores, and an uneven complexion all at once: 2 % niacinamide refines the skin texture, a mild complex of AHA, BHA, and PHA dissolves skin flakes and sebum, while centella, tea tree oil, calendula, and aloe vera soothe. The light texture is not sticky. For combination and oily skin. If you are new to acids, use it every other evening at first, with sunscreen in the morning.

#OOTD AHA-BHA Clarifying Serum

An exfoliating serum for the night: AHA, BHA, PHA, and papain exfoliate mildly, smooth the skin texture, balance sebum, and make clogged-looking pores appear finer. Described by the manufacturer as non-comedogenic. Massage a pearl-sized amount onto face, neck, and décolleté. For all skin types, including sensitive skin. Vegan.

SKIN1004 Madagascar Centella Poremizing Fresh Ampoule

Enlarged pores, a shiny T-zone, and still sensitive skin? Pink Himalayan salt draws impurities and sebum out of the pores, and a complex of nine peptides supports elasticity so that pores look finer. Centella, aloe vera, chamomile, and panthenol soothe at the same time. Free of fragrances, silicones, and sulfates. A second layer may follow on the nose, cheeks, and forehead.

Beauty of Joseon Glow Serum: Propolis + Niacinamide

The "honey glow" for skin that is prone to impurities and still wants to be radiant: 60 % propolis extract and 2 % niacinamide keep hydration and sebum in balance and make the complexion look finer and calmer. The viscous texture absorbs without a film and works under makeup. For oily, combination, and normal skin. Always finish with SPF in the morning.

For dry skin: hyaluronic acid, ceramides, and panthenol

SKIN1004 Madagascar Centella Hyalu-Cica Blue Serum

Thirsty and quickly irritated at the same time? The Blue Serum combines five types of hyaluronic acid with centella, ceramides, and panthenol: hydration, soothing, and barrier support in one step.

Fragrance-free, hypoallergenic, without mineral oil and parabens. The light texture is suitable for layering before the cream. For all skin types, especially dry and sensitive skin.

#OOTD Intensive Moisture Face Serum A.M

The morning serum for dry skin: eight different hyaluronan molecules and vitamin C provide intense hydration and make the complexion look fresher. The light formula gives a plumped-up feel and works as a primer under cream, sunscreen, and makeup. A pearl-sized amount on face, neck, and décolleté. Vegan.

For first lines and mature skin: collagen, PDRN, peptides, and bakuchiol

Medicube Triple Collagen Serum 4.0

More elasticity, more hydration, and a plumper, smoother-looking skin surface: the Triple Collagen Serum is the glow serum for the everyday "glass skin" look, with a light texture and no greasy feel.

Anua PDRN Hyaluronic Acid Capsule 100 Serum

PDRN (Sodium DNA), multiple hyaluronic acid, and collagen in a watery, light serum: long-lasting hydration, smoother texture, and a "dewy" glow without a heavy film. Fragrance-free and non-comedogenic, so also for skin that gets irritated quickly. In the evening, apply in two to three layers for extra plumpness. Note: the PDRN is usually derived from salmon. If you have a fish allergy, seek medical advice before use and test on a small area of skin first. More about the active in our PDRN guide.

APLB Exosome Collagen EX Serum

For skin that should look firmer and plumper: the 43.3 % exosome-collagen-cica complex combines hydrolyzed collagen with soothing centella, sea buckthorn gives glow, and beta-glucan, panthenol, and squalane provide hydration and strengthen the barrier.

PURITO Bakuchiol Timeless Bloom Revitalizing Serum

The gentle alternative to retinol: 1 % bakuchiol, peptides, and betaine reduce fine lines and an uneven skin texture, even for sensitive skin. The light texture does not weigh the skin down and leaves no greasy film. Pat a small amount onto face and neck after the toner. For all skin types. Vegan.

How to use the serum in the Korean routine

The serum comes after cleansing and toner and before the cream, morning and evening. Order: cleansing, toner, serum, cream, and sunscreen as the final step in the morning. Put two to three drops or one to two pumps in your palm, spread the serum over face and neck, and pat it in gently until it is absorbed. Only then follows the cream, which seals in the actives.

You can apply hydrating serums with hyaluronic acid, centella, or PDRN in two to three thin layers. Active serums with vitamin C, acids, retinol, or bakuchiol you do not layer and do not combine in the same step: vitamin C in the morning, acids or bakuchiol in the evening is the simplest split. Each of these serums needs sunscreen during the day.

Frequently asked questions

Do I need a serum if I already have a good cream?

A cream keeps hydration in the skin, a serum brings a concentrated active into it. If you have a specific goal, such as dark spots, redness, or first lines, the serum is the step that works on it. If you only want hydration, toner and cream are often enough.

Can I combine two serums?

Yes, if the actives are compatible. A hydrating serum can be layered with almost anything: first the thinner, watery one, then the thicker one. Vitamin C, acids, and retinol or bakuchiol you do not use in the same step, but split between morning and evening or between different days.

How long does it take for a serum to work?

You feel hydration and soothing immediately. Visible changes in dark spots, pores, or fine lines need regular use over several weeks. Do not keep switching products during this time, or in the end you will not know what worked.

Serum or ampoule: what is the difference?

The line is blurry. Ampoules are usually a bit more concentrated and often intended as a course of treatment, serums for daily care. With the products in this article, you can use both the same way: after the toner, before the cream.
