Skin brightener: Lemons are rich in vitamin C and citric acid, so they can help brighten and lighten your skin when used over time. Vitamin C is a great antioxidant for neutralizing free radicals and boosting collagen production. Lemons help lighten age spots, dark spots, or a fake tan gone wrong. Remember to wear SPF when using lemon juice on your skin, though, since the citrus fruit can make your skin more sensitive to UV rays.
Hair Lightener: Score dye-free DIY highlights with lemon juice! Apply it before you expose your hair to sunlight to score a sun-kissed color. The lemon juice can also help treat a dry scalp and dandruff, so apply it liberally.
