Using this ViBrowLash cream is a breeze. First, make sure you have the ViBrowLash Activator handy as you'll need it to activate the cream. Squeeze out the right amount of cream and mix it well with the activator. Then, carefully apply the mixture to your lashes and brows. Be gentle to avoid getting it in your eyes. This product is for professional use only, so if you're not experienced, it's a good idea to get help from a professional.

And remember, since it's free from gluten, lanolin, and nut oils, it's suitable for those with sensitivities to these substances.
