If you're not in love with the freckles or dark spots that appear on your skin, you may be looking for a way to lighten these marks on your skin. The citric acid in lemons can be used as a lightening agent, and when combined with glycerin makes a skin lightening lotion. Test this lemon skin lightener lotion on a small patch of skin before using it to make sure you don't have an adverse reaction.
Strain 2 oz. of juice from fresh lemons. You can help loosen the juice by rolling the lemon on a counter before you cut it, or you can put it in the microwave for just a few seconds. Do not put it in the microwave for too long, as you want the juice in it to be released but not start cooking.
Pour the 2 oz. of lemon juice in a clean container. Add 1 oz. of light or medium rum, then add the 1 tsp. glycerin.
Shake all the ingredients together until they are mixed well. Apply the lotion to the spots you wish to lighten. You may need to use the lotion regularly for a month or so before seeing results. Refrigerate when not in use.
