I am Canadian. Originally form Vancouver, BC... so I am not use to extreme heat.
With temperatures over 110 all week last week I found myself thinking "how do people live here?!" every time i got out of the car.
Ironically my favorite seasons are Fall and Winter...and I live in Southern California where it is all sorts of summer all year round.
With that said, my makeup routine has changed a lot since I've moved here. After much trial and error looking for products that wouldn't smear, bleed, smudge, melt, or wipe off during the I feel like I've found some that work great.
I've also used some of these products I've used on people who were in a wedding or getting married themselves, So I know they last through heat, sweating, nerves, tears and lots of dancing!
hope this helps!
