    For the price this is absolutely amazing peptide serum. I don’t have much of experience with other brands, however this is probably first skincare product that just makes my face feel tighter and wrinkles more subtle and smoother. It doesn’t completely eliminate fine lines, but since using it every morning before applying my sunscreen I can see my face being more hydrated, plumped and overall looks and FEELS incredibly soft.

    I finished 3/4 of the bottle and once I run out I will definitely repurchase because of all the anti-aging and hydrating benefits it gives me.

    😍Wow , ich bin sowas von begeistert von diese Marke Cosrx . Am Anfang habe ich mir Retinol creme bestellt um es auszuprobieren ,und direkt nach paar anwendungen meine Haut ist sooo glatt geworden . Da ich kleine Pickelchen hatte und hab alles mögliche ausprobiert , sogar zu collagen tabletten gegriffen , aber es hat mir nichts gebracht . Aber seit dem ich Cosrx retinol hab , meine Haut ist perfekt geworden . Deswegen ich habe mir direkt komplette set pflege produkte gekauft im wert von 350 eur 😂. Ich weis das es verrückt klingt , aber diese pflegeprodukte sind einfach WELTKLASSE 👀👍👍👍💘!!! Wo ich Niaciamid , Serum , Gel , Toner , Ampulen , Augencreme , Pads , Creme mit Schnecken schleim und Propolis ausprobiert habe von Cosrx , war ich mehr als begeistert .Ich bin soooo glücklich jetzt . Ich bin 37 aber viele denken ich wäre 20 ))Meine haut ist so am glänzen , soo glatt und die Poren sind soo klein geworden , ich habe keine Flecken , mein hautton ist gleichmässig geworden . Es hinterlässt kein Film , es klebt nicht , und sehr angenehm auf der Haut . Meine Haut ist sehr gut mit Feuchtigkeit versorgt .Unglaublich einfach . Ich dachte ich werde NIE so gute kosmetik bekommen für angeneme Preis . Und diese Geld was ich ausgegeben habe hat mir nicht leid getan . Sondern diese Qualität jeden Euro wert .Ich habe direkt es meine Mama und Freundin empfolen 😁. Mädels ,wenn ihr noch am zweifeln seid , denn kauft es euch ohne zu überlegen . Glaubt es mir , wenn ihr diese Marke auspribiert , egal welche Produkt , seit dem es wird eure lieblings pflege sein. Ich schwöre es euch !!! Das ist das beste was ich mir seit letzte zeit gekauft habe . Einfach nur 💥WOW 💥 Ich bin verliebt in alle Produkte von diese Marke .

    Das beste Serum bzw der beste Glow Booster, den ich jemals genutzt habe.

    Wer - wie ich - nur einen einzigen Pumpstoß nutzt, kommt trotz des höheren Preises lange damit aus.

    Da Cosrx jedoch im allgemeinen eine höherpreisige und hochwertige koreanische Skin Care Serie ist, ist der Preis ok. Idealerweise (so wie aktuell) im Rahmen einer Aktion bestellen, dann relativiert es sich ein wenig. 😉

    Glow (ohne "Fettglanz!) sowie Pflegewirkung sind direkt nach der Anwendung sicht- bzw spürbar.

    Nichts klebt, Serum wird sofort von der Haut absorbiert.

    Klare Kaufempfehlung. Von mir 4 (einhalb) Sterne.

    Tolle Hautpflege für straffe und elastische Haut
    Reviewed in Germany on 14 July 2025
    Brief content visible, double tap to read full content.
    Full content visible, double tap to read brief content.

    Ich habe das COSRX 6 Peptide Collagen Serum jetzt eine Weile verwendet und bin sehr zufrieden mit den Ergebnissen. Dieses Serum & Toner ist wirklich ein tolles Produkt, das meiner Haut zu einer sichtbar strafferen und elastischeren Textur verholfen hat.

    Hauterneuerung und Straffung:

    Das Serum enthält 6 Peptide, die nachweislich die Hautelastizität verbessern. Bereits nach wenigen Wochen der Anwendung konnte ich eine deutliche Verbesserung meiner Haut feststellen. Sie wirkt straffer und glatter, was für mich einen großen Unterschied gemacht hat, besonders im Bereich der Wangen und der Stirn.

    Beruhigende Pflege mit Niacinamid und Hyaluronsäure:

    Ich liebe, wie das Serum auch Niacinamid und Hyaluronsäure enthält, die meiner Haut zusätzlich eine beruhigende und feuchtigkeitsspendende Wirkung verleihen. Die Hyaluronsäure sorgt dafür, dass meine Haut den ganzen Tag über gut durchfeuchtet bleibt, während das Niacinamid hilft, den Hautton zu verbessern und eventuelle Rötungen zu minimieren. Es fühlt sich wirklich angenehm und erfrischend an, wenn ich es auftrage.

    Leichte Textur und schnelle Absorption:

    Die Textur des Serums ist leicht und zieht sehr schnell in die Haut ein, ohne klebrige Rückstände zu hinterlassen. Das macht es zu einem perfekten Produkt für die tägliche Hautpflege-Routine, da es gut mit anderen Produkten kombinierbar ist, ohne das Gefühl von Überladung oder Schwere.

    Beruhigender Hautpflege-Booster:

    Zusätzlich zur Straffung und Hauterneuerung hat das Produkt eine sehr beruhigende Wirkung. Besonders nach einem langen Tag oder bei Hautirritationen hat es meiner Haut Erleichterung verschafft und sie spürbar beruhigt.

    Fazit:

    Das COSRX 6 Peptide Collagen Serum ist eine hervorragende Wahl für alle, die nach einer effektiven Lösung für Hautstraffung und Hauterneuerung suchen. Die Kombination aus Peptiden, Niacinamid und Hyaluronsäure macht es zu einem besonders effektiven Pflege-Booster, der die Haut pflegt und gleichzeitig ihre Elastizität und Textur verbessert. Ich werde es definitiv weiterhin verwenden und kann es jedem empfehlen, der auf der Suche nach einer hochwertigen Korean Skincare-Pflege ist!

    Spürbar straffere, glattere Haut – perfekter Booster bei Problemhaut!
    Reviewed in Germany on 5 December 2025
    Brief content visible, double tap to read full content.
    Full content visible, double tap to read brief content.

    Ich bin 46 Jahre alt und habe mit Problemhaut zu kämpfen – unruhige Stellen, nachlassende Festigkeit und gelegentlich Rötungen. Das COSRX 6 Peptide Collagen Serum/Toner hat mich wirklich überrascht, denn schon nach kurzer Zeit wirkt meine Haut glatter, ruhiger und deutlich elastischer.

    Die Kombination aus 6 Peptiden, Niacinamid und Hyaluronsäure ist genau das, was reifer und empfindlicher Haut guttut.

    Die Peptide sorgen für spürbare Straffung und geben der Haut neuen “Bounce”.

    Niacinamid verbessert die Porenstruktur, mindert kleine Unreinheiten und macht das Hautbild insgesamt gleichmäßiger.

    Hyaluron schenkt intensive Feuchtigkeit, ohne zu kleben.

    Was ich besonders schätze: Obwohl es ein sehr wirksamer Booster ist, fühlt sich das Produkt extrem leicht und beruhigend an. Kein Brennen, kein Spannungsgefühl – selbst bei gereizter Haut absolut angenehm.

    Nach einigen Wochen Anwendung wirkt meine Haut straffer, frischer und insgesamt klarer. Make-up lässt sich besser auftragen und selbst Trockenheitsfältchen sind weniger sichtbar.

    Mein Fazit:

    Ein fantastischer All-in-One-Pflegebooster für alle ab 40+, die Problemhaut haben und gleichzeitig etwas für Straffung, Porenverfeinerung und Feuchtigkeit tun möchten. Ich werde es definitiv nachkaufen!

    Pelle compatta e pori minimizzati
    Reviewed in Italy on 23 April 2026
    Brief content visible, double tap to read full content.
    Full content visible, double tap to read brief content.

    Se la tua routine sembra aver smesso di dare risultati, questo booster ai 6 peptidi di COSRX è l'ingrediente mancante. Non va considerato come un siero tradizionale, ma come il "primo passo" fondamentale per risvegliare la pelle e potenziare tutto ciò che applicherai dopo.

    Formulazione e Texture (La scienza dei 6 Peptidi):

    La consistenza è acquosa, leggerissima e scivola sulla pelle con estrema facilità. Il mix di 6 diversi peptidi lavora su più fronti: compattezza, rughe sottili, elasticità e controllo dei pori. La presenza della Niacinamide e dell'Acido Ialuronico completa la formula, regalando un aspetto subito più riposato e una grana della pelle visibilmente più affinata.

    Risultati e Sensazioni:

    Assorbimento Istantaneo: Svanisce nella pelle in pochi secondi senza lasciare alcuna traccia appiccicosa. È la base perfetta sia per la routine del mattino che per quella serale.

    Effetto "Pore-Control": Ho notato un miglioramento reale nella visibilità dei pori e una produzione di sebo più equilibrata, grazie all'azione purificante e rassodante dei peptidi.

    Pelle Rimpolpata: Dopo una settimana di utilizzo, la pelle appare più "densa" al tatto e incredibilmente luminosa, eliminando quel grigiore tipico della stanchezza.

    Utilizzatelo come primissimo step subito dopo la detersione, a pelle nuda. Essendo un flacone generoso (150ml), non risparmiate sul collo e sul décolleté. Se usate altri sieri funzionali (come Vitamina C o Retinolo), applicate questo booster prima: aiuterà gli attivi successivi a penetrare meglio e a lavorare in sinergia.

    In sintesi:

    Un prodotto moderno, elegante e versatile che si adatta a ogni tipo di pelle. È il segreto per ottenere la famosa "pelle di vetro" coreana partendo dalle fondamenta. Rapporto qualità-prezzo eccellente per un formato così grande.
