Dark spots on your skin and neck might be a result of heredity, pregnancy, sun exposure or another skin issue, such as liver spots. Known as hyperpigmentation, these spots could be covered with makeup -- but you might want to try and solve the problem at the skin level. Lemon's mild bleaching and exfoliating properties often makes it easier to conceal these issues -- or remove them entirely.
Cut a lemon in half. Rub the darkened area on your neck with the lemon.
Clean the spot after a few seconds with water and a clean washcloth.
Rub the spot with concentrated lemon juice as an alternative to using a raw lemon. Clean the area with a clean cloth and water.
Repeat the application for a few days to a few weeks, or until you see satisfactory results.
Mix lemon juice with pure sugar to create an all-natural weekly exfoliant.
