I purchased Carpe for my 16 year old daughter. I’ve literally tried everything you can buy. My daughter was to the point she had to wear baggy dark shirts or sweatshirts. She would have a huge sweat ring around her armpits within an hour. Even if she wasn’t hot, she would have sweat dripping from her armpits. By day 2 of using Carpe, her armpits were still dry at the end of the day. I would highly recommend this!
