Age spots, also called liver spots or solar lentigines, are flat spots on the face, shoulders or arms and usually black, gray or brown in color. They are most common in adults over 40 who have spent time out in the sun. While they may look like the beginning signs of skin cancer, true age spots are harmless, though cosmetically displeasing.
If you're bothered by freckles or age spots, dissolve a pinch of sugar in 2 tablespoons lemon juice. Apply the mixture to each spot with a cotton ball or a facial tissue. Repeat every few days until the spots have lightened to your liking and given your skin a more even tone.
