Our experts answer

Is The Booster Black Lash Serum a mascara?

The Booster Black Lash Serum is a serum-mascara. It combines the intensity of a black mascara with the effectiveness of a fortifying serum. From the first application, it lengthens, defines and intensifies the eyes. Day after day, its targeted actives help strengthen lashes and improve their appearance.

Can I replace my usual mascara with The Booster Black Lash Serum?

Yes. Its formula was designed to be used on its own, every day. It delivers lash-by-lash definition, an intense black and a natural volume effect, without the stiff or overloaded effect of some traditional mascaras.

Is it suitable for sensitive eyes and contact lens wearers?

Yes. Its formula is tested under dermatological and ophthalmological control. Fragrance-free, alcohol-free and hormone-free, it is suitable for sensitive eyes as well as contact lens wearers.

Can The Booster Black Lash Serum be used every day?

Absolutely. Designed as a daily treatment, it can be applied every morning in place of a classic mascara. Regular use lets you enjoy both its immediate makeup effect and its long-term care benefits.

Does The Booster Black Lash Serum really help strengthen lashes?

Yes. Its formula combines Cressatine® HD, plant keratin and ORGANIC castor oil to act directly on the quality of the lash fiber. Used daily, it helps achieve visibly stronger, more resistant and denser lashes while instantly enhancing the eyes.

Why is the texture different from a classic mascara?

The Booster Black Lash Serum is first and foremost a lash treatment enriched with fortifying actives. Its texture was formulated to prioritize comfort, respect for the lash fiber and care benefits, while delivering a high-performance makeup result. This explains why it feels lighter and more supple than a conventional mascara rich in thick waxes.

incroyable
Mes cils sont très longs et définis quand je le mets, il était un peu sec au départ (surement dû au fait qu’on me l’a donné) donc j’ai ajouté un peu de sérum physiologique et il était parfait. Depuis je le mets pratiquement tous les jours, je trouve qu’il vaut tout à fait son prix. On sent à l’odeur qu’il est bio, ça peut ne pas plaire à tout le monde mais personnellement ça ne me dérange en aucun cas. Bref un des meilleurs mascaras que j’ai essayé !

Super !
Mascara au rendu très naturel, avec une brosse en silicone qui sépare bien les cils. Pas d’effet “faux cils”, mais un résultat parfait pour un maquillage léger au quotidien. Petit plus pour le soin intégré, c’est vraiment un vrai bonus.
