In a large mixing bowl, blend all the mentioned ingredients until it forms a downy but well-incorporated and smooth mixture.
Carefully pour the mixture into the top part of your double boiler and fill its lower portion with water.
Wait until the water in the boiler’s lower part starts simmering on stove’s medium heat range.
Once it starts boiling, use a large ladle to stir the mixture lightly for the next 5 to 8 minutes until the mixture’s cocoa butter and the beeswax melt fully.
Now turn off the heat of the stove, take away the double boiler and place on a smooth surface.
Keep on gentle stirring until the mixture cools down completely.
Once cool well, pour this mixture into a dry airtight jar or container and place in your refrigerator for some time, before applying it to the stretch marks.
