Heart Tanning Stickers or 3/4 Hearts also known as Small Hearts are a great way to show the love and measure your progress. It is always hard to see your results just by looking in the mirror. Tanning is a gradual process and it takes time but when you look each day and see a gradual change you don’t realize how dark you are getting. The only really effective way to effectively measure your tanning progress is to use a heart tanning sticker in the same spot each time you tan. Almost everyone is surprised by how tan they actually are once they have used a heart sticker for a few weeks.
