How to prevent aging spots ( blemishes) from growing and how to eliminate them?

Age spot prevention: Best way of preventing age spots (freckles) is to avoid sun exposure and use sunscreen. Some skin lesions that are considered age spots are actually benign growths, called seborrheic keratoses (sk). Pretty much everyone gets them. In some people this condition is hereditary, particularly if there are many sks. There is no good way of preventing these unfortunately. But they can be treated.
