Description
The research-based derma line of COSRX was born, a prescription solution that optimally blends customized high-efficiency ingredients to solve skin problems and delivers them safely and effectively to the skin.
This product is recommended for those who are concerned about blackheads/whiteheads, those who are worried about shine due to excess sebum, and those who are worried about rough skin texture due to dead skin cells.
It is an A-to-Z solution product that can take care of skin problems, from the roots to the traces.
Feel only the freshness by removing the greasy oil.
It is a liquid formula that is as light as water and is quickly absorbed to complete a smooth skin condition.
You can feel the four trouble care effects: sebum/oil care, pore care, dead skin care, and skin texture care.
COSRX is clean and earth-friendly, and it is easy to recycle with a dropper wiper that separates easily from the package.
Please dispose of the dropper head as general waste, the dropper cap and the dropper wiper as plastic, and glass tubes and containers as glass.
With an optimal combination of N_Acetylglucosamine, zinc P.A., and allantoin, the formulation helps to care for dead skin cells, remove sebum, and protect the skin.
*It is recommended to apply after toner and before cream.
High-content serums don’t only have to be used in the evening! It can also be used in the morning/afternoon.
When using as a morning care product, be sure to use a sunscreen with SPF 30 or higher to protect your skin and the ingredients.
Caution

*This is a normal phenomenon and there is no problem with the product, and it is safe to use.

Kupiłam ten serum i zauważyłam różnicę po kilku dniach. Skóra wygląda na świeższą, a pory są mniejsze. Ma lekka konsystencja, łatwo się wchłania. Dobrej jakości produkt za przyzwoitą cenę.

The serum works well for controlling oil. I noticed fewer blackheads after a few uses. It absorbs fast, which is great since it’s not sticky at all. Just be aware the color looks lighter than expected in person.

Suvi Saapuu serum tuntee ihon mukavammaksi ja raikkaammaksi. Puhdistava vaikutus tekee sen tavallisista huokosista kertaheitolla sileitä, vähemmän näkyviä! Jos kaipailee silmänympärysraikkautta tai vähän elastisuutta itseltä , tässä se saattaisi olla avain täydellisyyteen.
Aroha from Sydney, Australia –
Aroha was initially skeptical about using a serum aimed at managing troublesome skin issues. It seemed almost too easy, which left me wondering whether it could really make that kind of impact without compromising quality. However, after consistent use of the COSRX Niacinamide 15 Serum, what unfolded proved to be surprisingly uplifting for my complexion! The oiliness diminished significantly and the texture became remarkably smoother – feels like I’ve shed years off this busy lifestyle face.
How refreshing it’s become: an assurance I’d recommend heartily in spaces where routine is mundane!

تمكنت هذه السيروم من إعطاء شعور متجدد لطيف بفضل التركيبة الخفيفة التي سرعان ما امتصت البشرة. وبالرغم من استخدامه فقط في فترة قصيرة، إلا أنني أشعر بالتغيرات الفعلية، بما فيها تصفية المسام وتقليل اللمعة المزعجة.

अच्छा फील हुआ. छोटे दाने कम हुए और ओवरी नजर नहीं आ रहा. पैकिंग अच्छी थी लेकिन एक हफ्ते तक आई.
Freya from Madrid –
Como alguien que ha luchado contra las imperfecciones de la piel, debo decir que el suero COSRX con niacinamida fue un descubrimiento fascinante. Después de semanas probando productos diferentes en Madrid, me sentí desanimada por los resultados decepcionantes. Sin embargo, este suero liviano y refrescante cambió mi rutina para mejor. Al aplicarlo cada mañana, noté cómo disminuían los brillos causados por el exceso de grasa; además logró reducir mis poros visibles como nunca antes había experimentado.

I noticed less shine and fewer breakouts. The texture is light, like water. It absorbs quickly too. Shipping took about a week but it arrived in good condition.

Wanna say goodbye to my rough skin? This serum does the trick! So light, feels like magic. Goodbye shine and hello smoothness!

Das Serum hat schnell gewirkt und lässt die Haut frischer aussehen. Es zieht sofort ein, ohne zu kleben.
Rafael de Almeida from Curitiba, Brasil –
Quando vi o COSRX The Niacinamide 15 Serum, não tinha certeza se mais um produto seria a resposta para as minhas frustrações com pele oleosa e textura irregular. Testei inúmeras opções sem resultados realmente eficazes e minha esperança já estava baixa. Contudo, esse sérum me surpreendeu! Após algumas aplicações diárias, notei uma diferença significativa na aparência dos poros e até mesmo na redução da oleosidade que sempre esteve presente no meu rosto. A absorção é instantânea; ele deixa um toque leve enquanto cuida profundamente da saúde cutânea. Minha pele parece mais fresca e radiante agora — definitivamente valeu a pena dar essa chance!
Luz María Olivares from Mexico City, Mexico –
As someone living in vibrant Mexico City, where the air feels thick with cultural richness and occasional pollution, I’ve been on a quest for skincare that speaks to my urban lifestyle. COSRX The Niacinamide 15 Serum caught my eye not just because of its focus on pore minimization but due to the promise of fresh skin amidst humidity-induced sheen. Its watery consistency slips onto my face seamlessly and absorbs quickly—like it’s helping me shed yesterday’s bustle off without weighing me down. Compared to another popular brand here which felt heavy like putting honey on toast, this serum offers freedom instead of tackiness—a refreshing solution that’s kind to both surface shine and deeper blemishes.

最初は本当に効くのかなと半信半疑でしたが、COSRXのナイアシンアミド15セラムを使ってみて、大きな変化に驚いています。皮脂分泌が気になる毎日なのですが、このセラムのおかげで肌が少しずつ整っていく感じがあります。特に黒ニキビや白ニキビに悩んでいた私には嬉しい結果です。この軽やかな液体はすぐになじむので、メイク前でも全然ストレスにならず、お昼までツヤ感も持続します。値段以上の効果だと思いました！
