This Valentine's, put the heat of your love to the test and win free double flights to cool off. #lovethermometeroboticário. I will tell you a love story now. Once upon a time there was a boy that, on Valentines day, gave a Love Thermometer Kit from o Boticário to his girlfriend. And just like that, their love’s temperature spread through the roof, but when they realised that they also have won a trip to a European city, well, their passion became so hot that they had to choose a cooler city to cool off. Valentine's campaign proposal to O Boticário.
