Yes, you really do.
-because it's the correct thing to do.
We know, we know, we' read and hear all the talk about using other applicators too - like Q-tips, eyeliner brushes, etc....
But the Latisse applicator brushes are there for a reason -
1. They come pre-packaged two at at time - in a sterile blister pack. That's pretty important. Sterile applicators really help protect your eye so you do not get infections from common bacteria growing on other applicators. You have to admit - pink eye wouldn't look good even if your eyelashes are long. It's a safety kind of thing doncha know.
2. They were specifically designed to hold the correct dose....one drop per applicator. Per eye.
3. More importantly - they are specifically designed to also dispense the correct dose.....(lightbulbs going off, eh?)
So that way you do not increase the risks for potential side effects - like redness, itchiness, hyperpigmentation, etc....pretty clever, eh?
So please. Only use the sterile applicators that come with the solution for best results.
