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
*Due to the characteristics of the highly concentrated serum formulation, which has a high content of active ingredients, if the content spills while opening and closing the container and is continuously exposed to the air, the active ingredients may become visible.
*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.

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.

अच्छा फील हुआ. छोटे दाने कम हुए और ओवरी नजर नहीं आ रहा. पैकिंग अच्छी थी लेकिन एक हफ्ते तक आई.

Das Serum hat schnell gewirkt und lässt die Haut frischer aussehen. Es zieht sofort ein, ohne zu kleben.

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!
