Vogue | Best Eyelash Serums for Longer Lashes

Blink Brow Bar’s lash oil features a cocktail of ingredients which are both reparative and regenerative.

Castor oil will increase blood flow – which subsequently promotes hair growth – while jojoba oil boasts soothing and conditioning properties.

Designed for overnight use, simply apply it like mascara before bed and your lashes will feel strengthened and hydrated in a matter of weeks.
