I have the bad habit of not using a sun protection whenever I go out in the hot midday sun. Usually, I just jumped into the car, drive and though I can feel the heat on my face, I am just too lazy to apply a sun protection cream. The reason is because I hate the icky, sticky feelings on my face.
That's why a age spot remover seems like a good idea to me because it sort of saves me from getting dark spots. As I age, I tend to get brown spots easier than previously. So, yes, a spot remover is a saviour.
