This brand is known for color that lasts and does not need to be reapplied.
I reapplied the mascara to the wand then dabbed it across the bottom lashes the same way.
Sunblock alone is not a good option because it wears off quickly and needs to be continually reapplied.
It does take extra work as most organic pesticides must be reapplied after rain or extreme heat, but it's well worth it.
These solutions usually work quite well, but will need to be reapplied regularly.
