Steckbrief
Produkt
Long4Lashes Wimpernserum (FX5-Formel), Pinsel-Applikator wie ein Eyeliner
Wirkstoff
Ein Prostaglandin-Analogon – laut Inhaltsliste im Herstellershop Bimatoprost, in älteren Händlerangaben Isopropyl Cloprostenate
Anwendung
Laut Hersteller einmal täglich, abends, auf die abgeschminkte obere Wimpernlinie
Erhältlich
Online und im Handel; die Verfügbarkeit in Deutschland schwankt. Daneben gibt es inzwischen ein „Day & Night Double Serum“ des Herstellers, das laut Inhaltsliste ohne Prostaglandin-Analoga auskommt.
Für wen
Erwachsene mit kurzen oder schwachen Wimpern, die die Hinweise zu Nebenwirkungen kennen und akzeptieren
Nicht für
Schwangere und Stillende, bei Augenerkrankungen, nach Augen-OPs oder bei Glaukom-Behandlung – hier vorher ärztlich abklären
Wie Long4Lashes wirkt
Prostaglandin-Analoga wurden ursprünglich als Augentropfen gegen erhöhten Augeninnendruck eingesetzt. Dabei fiel auf, dass Patientinnen und Patienten längere, dichtere Wimpern bekamen. Kosmetische Wimpernseren nutzen diesen Effekt: Sie verlängern die Wachstumsphase der Wimpern. Deshalb gelten Seren mit diesen Stoffen als die stärker wirkenden – und deshalb werden sie auch kritisch gesehen.
Der Wissenschaftliche Ausschuss für Verbrauchersicherheit der EU (SCCS) hat im Februar 2026 in seinem endgültigen Gutachten mehrere Prostaglandin-Analoga in Wimpern- und Brauenseren als nicht sicher eingestuft, darunter Isopropyl Cloprostenate. Eine rechtliche Beschränkung ist bislang (Stand Oktober 2026) nicht beschlossen. Die französische Behörde ANSES warnt vor möglichen Veränderungen der Augenfarbe.
Mögliche Nebenwirkungen
Rötung, Brennen oder Juckreiz am Lid und am Auge
Dunklere Verfärbung der Lidhaut
In seltenen Fällen eine Veränderung der Irisfarbe, vor allem bei hellen, gemischtfarbigen Augen
Härchenwachstum dort, wo Serum auf die Haut gelangt
Bei Beschwerden das Serum absetzen und bei anhaltenden Symptomen augenärztlich abklären lassen. Wer Augentropfen gegen Glaukom verwendet, sollte Seren mit Prostaglandinen nur nach Rücksprache nutzen.
Long4Lashes und unsere Alternative
1
Unsere Empfehlung – ohne Prostaglandine
Lazru Wimpern- und Augenbrauenserum
Ein Serum für Wimpern und Brauen ohne Prostaglandine und ohne Hormone – laut veröffentlichter Inhaltsliste mit den Wirkstoffen Procapil™ und AnaGain™ plus Koffein. Die Hautverträglichkeit wurde von Dermatest mit „sehr gut“ bewertet (06/2022). Erste Veränderungen nennt der Hersteller nach einigen Wochen, deutlicher nach zwei bis vier Monaten – individuell verschieden.
Ein bekanntes Serum mit einem Prostaglandin-Analogon. Die Wirkstoffklasse regt das Wimpernwachstum nachweislich an. Dafür sollten Sie mögliche Nebenwirkungen kennen und das Serum sorgfältig nur an der Wimpernlinie auftragen.
Spricht dafür
Wirkstoffklasse mit belegtem Effekt auf das Wimpernwachstum
Alle Wimpernseren im Überblick – mit und ohne Prostaglandine – finden Sie in unserer Wimpernserum-Bestenliste. Ebenfalls mit Prostaglandin-Wirkstoff arbeitet RevitaLash.
Häufige Fragen
Enthält Long4Lashes Hormone?
Nicht im Sinne von Sexualhormonen. Es enthält aber ein Prostaglandin-Analogon, also einen Abkömmling der Prostaglandine – gewebshormonähnlicher Botenstoffe. Deshalb wird oft von „Hormonen“ gesprochen.
Wirkt Long4Lashes?
Prostaglandin-Analoga gehören zu den Wirkstoffen mit dem deutlichsten Effekt auf das Wimpernwachstum. Wie stark und wie schnell, ist individuell verschieden.
Welche Nebenwirkungen hat Long4Lashes?
Möglich sind gereizte, gerötete Augen, eine dunklere Lidhaut und selten eine Veränderung der Augenfarbe. Bei Beschwerden absetzen und ärztlich abklären lassen.
Gibt es eine Alternative ohne Prostaglandine?
Ja. Unsere Empfehlung ist Lazru, ein Serum für Wimpern und Brauen ohne Prostaglandine und ohne Hormone. Mehr dazu im Wimpernserum-Vergleich.
Darf ich Long4Lashes in der Schwangerschaft verwenden?
Nein, davon raten wir ab. Sprechen Sie mit Ihrer Ärztin, Ihrem Arzt oder Ihrer Hebamme.
