Cocoa beans have long been used for their brown dye. Unflavored coffee grounds can naturally add color to hair and skin. While self-tanning lotions and creams are available to purchase, these are made with chemicals and can add up in cost. Use coffee grounds correctly to safely add natural-looking pigment to your skin tone.
Cleanse the skin you wish to darken thoroughly with soap. Exfoliate the area with a loofah sponge or exfoliating gloves.
Fill a bath with warm water. Add 1 cup of coffee grounds. Stir the bath. Soak in the water. The longer you soak, the darker your skin will become. Alternatively, rub wet coffee grounds over the skin you wish to darken and let sit for 30 minutes.
Rub coffee grounds gently and evenly on your facial skin. Avoid rubbing into your eyes, nose and ears. Rinse completely and dry as normal.
Test the darkening process weeks before an important event to determine the amount of soaking time that works best for your skin.
