Castor oil for eyelashes and eyebrows
This is the most-asked question we get at the market, usually while someone is holding the brow wand. The honest answer has two halves: no, it will not grow them, and yes, they will probably look better anyway.
Will castor oil grow my eyelashes?
No. There is no scientific evidence that castor oil makes eyelashes grow. What the research does support is that it can make lashes look thicker and glossier, because the oil coats each hair and adds shine.
Coated lashes catch light and look darker and denser. Conditioned lashes also break off less when you rub your eyes or take off mascara, so fewer of them go missing. Both of those are worth having. Neither is growth.
Is it safe to put near your eyes?
Near, yes, with care. In, no. The American Academy of Ophthalmology's position is to use sterile products around the eye — a cosmetic oil in a wand tube is not sterile, and getting oil into the eye itself causes blurring and irritation.
Practically: one light pass along the brow and along the lash line at the base, at night, on a clean face. Not on the lash tips, not close enough to wick into the eye. If any gets in, rinse with cool water and it will clear.
Patch test first if your skin reacts easily. Allergy to castor oil is uncommon but it exists, and the skin around the eye is the worst place to discover it.
Why ours is thinner than the hair oil
Neat castor oil on a lash line is too heavy — it smears, it migrates into the eye overnight, and it ends up on the pillow rather than on you. Our brow and lash serum is the same three oils cut much thinner for exactly that reason. It is a conditioner in a wand, and we do not call it anything else.
