Safe to Wear Latisse During the Daytime?

Night application more logical, at night there is no mascara ,no make up nad no possibility of sweating that can diffuse the latise on the skin which you do not want to have

Latisse is meant to be used on clean skin. Since most women use eye makeup of some type, that means you may not get the best application if you have eye cream liner or mascara on. Plus, blinking, rubbing, etc during the day could potentially transfer more of the product into the eye.
You'll likely get the most benefits by applying at night and avoid increasing any of the small possible side effects as well.
