Natural Skin Care

When mixed to a paste with salt or sugar and allowed to remain on the skin for half an hour once each day, lemon juice may lighten brown splotches caused by the sun.

Milk, in its many guises, is a time-tested skin lightener. Mix 3 tablespoon milk and 1 teaspoon lime juice, it can be sponged on to remove a tan.
 
Yogurt, plain or blended with an equal amount of buttermilk, can be used as night cream to ameliorate a fading tan.

Aloe vera gel. Smooth over sun-darkened freckles or brown spots at least twice a day.
 
Watercress. Place a freshly washed bunch of watercress in 2 cups cold water. Bring to a boil, cover, and simmer for 10 minutes. Strain and store in the refrigerator. Each morning and evening, sponge the chilled liquid over your fading tan, allow it to dry, then rinse with water.
