Neck and hands betray best the years pass, and if the skin is stained, some extra years are added. Brown spots, darker or lighter, are caused most often by prolonged exposure to the sun without protective creams. Other times, they are the consequence of liver problems, of birth control pills or of certain allergies or intolerances. Here’s an herbal remedy for alleviating dark spots: Mix half a teaspoon of sugar with the juice of half a lemon fruit. Apply the solution on the stain and let it act 10 minutes, then rinse. The sugar granules and bleaching acids in lemon juice will attenuate stains and the skin will look smoother and younger.
