Do you have sensitive ears? Try this easy trick : Just use vaseline. Dip the pointy part of your earrings in the vaseline. Then put them in your ears like normal. The vaseline seems to coat the earrings and will prevent your ears from getting sore.
Vaseline in what my dermatologist recommends to keep one's skin moisturized. This is what I use & it is better than any lotion or after-tanning lotion that I have found! Makes my skin so smooth & moisturized!
