Boil 3/4 cup of water in a tea kettle, pot or in the microwave for a few minutes. Turn the burner off, and remove the water from the burner. Steep three bags of black tea in the water for 10 minutes.
In a blender, add 1/4 cup coconut oil, 1/4 cup pure lanolin and 1/4 cup of the black tea. Blend the mixture for several seconds, then stop and add the remaining black tea. Continue blending the mixture until the oil is evenly blended.
Pour the lotion into an empty squeeze container, such as a clean, empty baby oil bottle or ketchup bottle that's been cleaned. Squeeze a quarter-size amount of oil onto your hand, and gently rub it on your skin before tanning.
To prevent a sunburn, set a timer for 15 minutes before tanning under the sun or in a tanning bed. The lotion can also stain clothing, so use caution when applying the lotion around clothes.
