I spent too much time in the sun as a teen. By college, I already had brown sunspots splattered all over my chest. I hated them so much, I avoided v-necks and strapless tops until my mid-twenties, when I had the spots zapped off with a laser. Diligent skincare, sunscreen, peels and some touchup lasering has kept new dark spots mostly at bay for me. However, since I turned 40, a new kind of spot has started to appear: white ones.
