Senile purpura bruises and treatment options

I ( and a friend or 2) love gardening. Even with wearing long sleeves while working outside, (today it was about 76 degrees by 8 AM here), I still get poked or scratched. The resulting bleeds and the bruises are way out of proportion to the cause. Anybody have a good suggestion how to cover up some of the bruises on my lower arms (elbow to wrist) so I don’t look so abused when going out in public? Meaning, make-up tricks. Tomorrow it will be around 94 degrees again here, so long sleeves out and about are not what I want to wear going forward.
