Summarize this article:

Aloe has remarkable natural healing properties and is a great natural remedy to use on unwanted sunspots. If you’re using a cream, apply a generous amount to the skin of your face, arms, and other sunspot-afflicted areas once in the morning and once in the evening. If you’re using the leaves of an aloe plant, squeeze the pith out from a 1 inch (2.5 cm) section and smear it directly onto your sunspots.  Look for aloe vera gels at health-food stores or in homeopathic medicine sections. Large pharmacies may also carry aloe vera gel. Look near the sunscreen and other skincare products. If you’d prefer just to purchase an aloe plant, look at a large plant nursery. Vitamin E has been proven to help lighten dark spots on the skin, including unwanted sunspots. Swallow 1 vitamin E tablet in the morning and 1 more at night to help lighten sunspots. Or, add vitamin E to your diet by upping your consumption of foods rich in vitamin E. These include foods like citrus fruits, papaya, spinach, broccoli, and tomatoes You can purchase both vitamin E oral tablets and liquid gel at a large pharmacy or drugstore. Cut 1 large lemon into quarters and hold a lemon section against your sunspots for 10–15 minutes per day. Lemons are mildly acidic, and the acid in the fruit aids in lightening dark sunspots. You’ll begin to notice that your sunspots are visibly lighter after about 2 months of daily use.  Rather than throwing away the sections of lemon that you don’t use each day, store them in a plastic bag in your refrigerator and use them the next day. Daily lemon application can also help to remove any dead skin cells from your face, arms, and shoulders. Take a sharp kitchen knife and chop 1 large red onion up into 6-8 large chunks. Pick up 1 of the onion chunks and rub it across a dark sunspot for about 30 seconds. The acid in the onion helps to lighten up the dark color of sunspots. Because the onion’s acid is relatively weak, you’ll need to continue the home treatment for months before you see much of a result.
Apply aloe vera gel twice a day to heal sun-damaged areas. Take vitamin E capsules by mouth twice daily to reduce sunspots. Slice a fresh lemon and apply it directly to your sunspots. Cut up a red onion and rub it over the sunspots.
