I reapply only if I go out after work and depending on what I'm doing. In a normal case, I will blot with Boscia Green Tea Linens (so my make up doesn't get cakey), reapply a little powder, a touch of blush, a fresh coat of mascara and some lipstick if I so choose on a given day.
In a not normal case, such as a date, I will go home for an hour and look in the mirror every five minutes obsessively to make sure my make up hasn't moved and keep reapplying until it's time to leave. Then I look like a clown. Good thing its dark at night..
