Frequently Asked Questions

What is breathable nail polish?

Typical nail polish creates an impermeable layer when applied. Essentially, it seals our nails off from oxygen and hydration, which inevitably results in brittle and unhealthy nails. It’s often overlooked, but our nails need hydration and oxygen too. However, breathable nail polish creates a permeable layer, allowing your nails to breathe and stay hydrated. 

Is Mersi nail polish vegan?

Yes, our nail polish is PETA Certified Vegan & cruelty-free. 

Is Mersi nail polish Halal? 

Yes, our nail polish is made in accordance to Islamic law and Certified Halal by ISWA Islamic certification department. We understand it can be confusing to the word “Halal” used in reference to nail polish since it is often associated with food. However, it’s not limited to food. The word translates to “permissible” in English. It can be used to describe anything that’s permissible according to Islamic law. Our nail polish is free of animal byproducts, prohibited alcohol, and has been lab certified for water permeability. This ensures that it’s suitable for use during Ablution.

Does it peel off or easily chip?

Our breathable nail polish formula is non-peelable and made to perform. It’s far more durable than early generations of breathable formulas. It’s chip resistant and lasts up to 10 days. Maximizing performance while maintaining breathability was or main priority during research & development stages of our formula. We take pride in the results we were able to achieve.  

Is rubbing required during Ablution?

Yes, rubbing each nail at least once under running water is required to ensure permeability.
