Think all serums are created equal? Think again. Between ultra-innovative formulas from Seoul and natural active ingredients reinvented by K-Beauty, choosing the best Korean serum in 2025 is practically an art form. But don't panic: we've prepared a comprehensive overview, balanced between glow, anti-aging, and anti-blemish benefits , so your skin can find its perfect match.
And if you don't yet know what type of skin you have, Holy Skin offers a free skin diagnosis , an ultra-useful step before you embark on the fascinating world of Korean serums.
Why have Korean serums become so essential? 🌸
K-Beauty has this healthy obsession: treating the skin deeply, not just concealing it. Korean serums are true concentrates of active ingredients: lightweight texture, rapid absorption, visible results. Unlike some Western skincare products that are often too rich or too harsh, Korean formulas focus on balance: hydrating, repairing, and protecting .
Three major trends are expected by 2025:
-
The return of ancestral ingredients such as ginseng or Centella Asiatica .
-
The rise of glow formulas based on niacinamide and propolis.
-
And a wave of anti-dark spot serums combining gentle acids and botanical extracts.
The result? Plump, luminous and soothed skin, without compromise.
Top 6 best Korean serums in 2025 ✨
Ready to discover the stars of the moment? Here are the six gems that dominate skincare routines in 2025, tested, approved and adored by K-Beauty fans.
1. Beauty of Joseon – Glow Serum: Propolis + Niacinamide
An undisputed classic! This Korean serum embodies the philosophy of hanbang (traditional medicine). Propolis soothes inflammation and boosts cell regeneration, while niacinamide refines skin texture and brightens the complexion.
Ideal for combination to oily skin, it balances sebum production while providing a natural glow. If you want to achieve a radiant complexion without the oily residue, this is the one for you.
2. Beauty of Joseon – Revive Serum: Ginseng + Snail Mucin
The more “anti-aging” version of the previous one. Ginseng stimulates microcirculation and revitalizes tired skin, while snail mucin (yes, really!) repairs tissues and reduces fine lines.
This Korean anti-aging serum is a gem for those who want to prevent skin aging without weighing it down. Fluid texture, subtle tightening effect, gradual radiance: everything we love.
As a bonus: it works wonderfully in a minimalist routine, with just a Korean facial cleanser and a light Korean moisturizer .
3. Some By Mi – AHA, BHA, PHA 30 Days Miracle Serum
Are you struggling with blemishes? Here's the hero for spot-prone skin. This Korean anti-blemish serum combines three exfoliating acids:
-
AHA to smooth the surface,
-
BHA to unclog pores,
-
PHA for gentle and moisturizing exfoliation.
In 30 days, skin is smoother, more even-toned, and scars are visibly reduced. No wonder it's one of the brand's global bestsellers.
💡 Best used in the evening, followed by a soothing cream and Korean sunscreen the next day, of course!
4. SKIN1004 – Madagascar Centella Asiatica 100 Ampoule
If there's one ingredient we'll see everywhere in 2025, it's Centella Asiatica . And SKIN1004 offers an ultra-pure version: 100% Centella extract from Madagascar, renowned for its calming and healing properties.
This serum-ampoule is a perfect ally for sensitive and reactive skin : it reduces redness, strengthens the skin barrier, and promotes healing. In short, a real "reset" for your skin.
If you're looking for a minimalist yet ultra-effective serum, this is the one for you. And for even more results, incorporate it into a combination skin routine .
5. AXIS-Y – Dark Spot Correcting Glow Serum
Small tube, big effect. This Korean anti-dark spot serum directly targets areas of hyperpigmentation thanks to a winning duo: niacinamide + tranexamic acid .
The result: a more even complexion, visibly faded blemishes, and a gradual glow without irritation. It's perfect for those who want to treat post-acne marks while maintaining light hydration.
It is also one of the most recommended products in Holy Skin diagnoses for combination or blemish-prone skin.
6. Medicube – Triple Collagen Serum
A must-have for skin seeking firmness! This Korean collagen serum combines three types of collagen (macro, micro, and nano) for optimal penetration. It plumps the skin, redefines facial contours, and improves elasticity.
Its silky texture melts in instantly without any stickiness. After a few weeks, skin appears firmer, denser, and above all, more radiant.
It's a favorite for mature or dehydrated skin, but it's also suitable for women in their thirties who want to prevent loss of firmness now.

The secret to the effectiveness of Korean serums 💫
What differentiates Korean serums from others? Their synergy of active ingredients and their gentle yet effective formulation .
They often avoid harsh ingredients like alcohol or synthetic perfumes and prefer fermented extracts, medicinal plants and natural biotechnologies .
Over 70% of Korean consumers now use two different serums in their daily routine: one in the morning (for glow or hydration) and one in the evening (for anti-aging or anti-dark spots). And guess what? It's a habit that's also increasingly common in France.
FAQs about Korean serums 💬
When should I apply my serum?
Always apply serum after cleansing and before moisturizing. This is the step where your skin is most receptive to active ingredients. If you use several serums, start with the one that has the lightest texture.
How long before I see results?
Between 2 and 4 weeks depending on the active ingredients. Korean serums emphasize consistency: the results are long-lasting, not instantaneous.
Can several Korean serums be combined?
Yes! It's even recommended: an anti-dark spot serum in the morning, a collagen serum in the evening. The important thing is to avoid overly strong combinations (for example, acids + retinoids).
Are Korean serums suitable for sensitive skin?
Absolutely. Most Korean formulas are designed to strengthen the skin barrier. Simply opt for gentle ingredients like Centella Asiatica or propolis.
