Lash serum while pregnant

Brittany

I’m a licensed cosmetologist, so I feel like I should know the answer to this but I’m confused. I just removed my lash extensions and was recommended to get Babe Lash growth serum! Just bought it came home and it says don’t use while breast feeding or pregnant 🙄 anyone know if this is a legit concern or it’s just to cover their asses? It’s purely topical so I’m confused why this would have any negative effect.
