When most people think of bug repellent, they picture a spray.

But when I began formulating a natural mosquito repellent for Kosmatology, I quickly realized that sprays weren’t the best option—especially for families with young children.

As a pharmacist and formulator, safety was my first priority. One concern that kept coming up was inhalation. Even if a bug repellent is safe to apply to the skin, that doesn’t necessarily mean it should be inhaled into the lungs.
