When your face is exposed to the sun, the ultraviolet radiation in the sun affects melanin in the skin. Melanin is a pigment that gives the skin its color. Over time, UV radiation causes permanent changes in color that can appear much like large freckles--age spots--on the face. Age spots are a sign of premature aging and can make you appear older than you are. If you experience these signs of sun damage, treatments at home may help reduce the occurrence.
Lemons contain citric acid, which is an alpha-hydroxy acid used to encourage cell turnover in the skin. According to DocShop.com, lemons are one of the most potent skin-lightening remedies. To utilize its effectiveness, squeeze lemon juice onto your finger or a cotton swab and apply to the age spot. If applying in the morning, leave on for 30 minutes, then remove. If applying at night, leave on overnight, if possible, according to homeremediesweb.com. You should begin to notice results in two months.

Castor oil is derived from seeds of the ricinus communis bean, according to GrannyMed.com. Sun damage can cause scaly growths called actinic keratoses, but castor oil can treat these rough spots. You can purchase castor oil at most health foods stores and discount superstores. For best benefits, apply the castor oil directly to the age spot. It will penetrate deeply into the skin and can smooth out these rough, sun-damaged spots, according to DocShop.com. Because it also has anti-inflammatory properties, it aids in reducing sun-damaged spots.
