Les sérums pour cils se distinguent surtout sur un point : contiennent-ils ou non un analogue de prostaglandine ? De là dépendent l’efficacité, les effets indésirables possibles et le choix du sérum qui vous convient.
ARBUTI Hair Salon · Mis à jour octobre 2026
La différence essentielle
Sérums pour cils sans et avec analogues de prostaglandine

Grossesse
Seulement après avis médical
Ne pas utiliser
Comment les repérer
Aucune des substances citées à droite dans la liste d’ingrédients
Attention aux arguments publicitaires : « sans hormones » ne veut pas forcément dire « sans prostaglandines ». Plusieurs marques mettent en avant « sans hormones » alors que leur sérum contient un analogue de prostaglandine. Seule la liste d’ingrédients fait foi.
Les sérums pour cils comparés

Notre choix sans prostaglandine
Lazru sérum cils et sourcils
Un sérum pour les cils et les sourcils, sans prostaglandines ni hormones. La liste d’ingrédients publiée mentionne les actifs Procapil™ et AnaGain™, ainsi que caféine, ginseng, biotine et acide hyaluronique. Dermatest a jugé la tolérance cutanée « très bonne » (06/2022). Selon le fabricant, les premiers changements apparaissent au bout de quelques semaines, plus nets après deux à quatre mois – variable d’une personne à l’autre.
Les points forts
Sans analogues de prostaglandine ni hormones – liste d’ingrédients publique
L’un des sérums les plus connus au monde. Le fabricant indique lui-même que son actif est un analogue de prostaglandine (cloprostenol ethyl amide). Effet net – avec les effets indésirables possibles typiques de cette classe. Plus de détails dans notre article sur RevitaLash.

Vérifiez la liste INCI à la recherche d’analogues de prostaglandine. Les marques sérieuses publient la liste complète.
Tolérance
Près des yeux, la tolérance compte double. Un test dermatologique de tolérance cutanée est un plus – il ne prouve toutefois aucune efficacité.
Attentes
Les cils poussent par cycles de plusieurs semaines. Les fabricants sérieux parlent de mois, pas de jours. Des promesses comme « deux fois plus longs en 15 jours » sont un signal d’alerte.
Application
Un pinceau fin, comme celui d’un eye-liner, facilite une pose précise au ras des cils.
Cils et sourcils
Certains sérums sont prévus pour les deux. Cela évite un deuxième produit si vos sourcils se sont aussi clairsemés.
Tout dépend de ce que vous êtes prête ou prêt à accepter. Les sérums aux analogues de prostaglandine ont l’effet le plus net – avec des effets indésirables possibles. Pour un soin doux sans prostaglandines, nous recommandons Lazru.
Les sérums pour cils fonctionnent-ils vraiment ?
Les sérums aux analogues de prostaglandine ont un effet prouvé sur la pousse des cils. Pour les sérums sans ces substances, les données reposent le plus souvent sur des études des fabricants d’actifs ou sur des tests d’utilisation ; l’effet est plus doux et varie d’une personne à l’autre.
Combien de temps avant qu’un sérum pour cils agisse ?
Comptez plusieurs semaines à plusieurs mois. Les fabricants de sérums sérieux annoncent de premiers changements au bout de quelques semaines, plus nets après deux à quatre mois.
Les sérums pour cils sont-ils sûrs ?
Le comité scientifique européen (SCCS) a jugé en 2026 les sérums aux analogues de prostaglandine non sûrs dans les cosmétiques ; une restriction légale n’a pas encore été adoptée. Les sérums sans ces substances sont considérés comme mieux tolérés. En cas de maladie des yeux et pendant la grossesse, demandez d’abord l’avis d’un médecin.
Peut-on utiliser un sérum pour cils sur les sourcils ?
Seulement si le fabricant le prévoit. Lazru et le RefectoCil Lash & Brow Booster sont conçus pour les cils et les sourcils.
