Set up a double boiler by putting water in a pot on the stove and setting the heat so that the water simmers. Place a heatproof bowl into the pot so that the heat from the water can easily heat the bowl. Select a bowl that fits well into the pot without falling in. Make sure the bowl is heat proof so that it does not crack or explode with the heat and ruin your bronzing ingredients.
Melt the Jojoba oil, Evening Primrose oil, emulsifier and beeswax in the heatproof bowl on the double boiler. Once the oils and waxes are melted, use an immersion blender or whisk to completely combine them. These oils and waxes are natural and good for your skin, unlike commercial bronzing lotions, which may contain a variety of chemicals.
Blend or whisk in the distilled water into the melted oils and waxes. Distilled water has been purified and does not have additives that could interfere with the lotion.
Add in the preservative in the amount indicated on the packaging. Cosmetic preservatives can be purchased from cosmetic suppliers, soap making stores or online. You need to add a preservative so that bacteria cannot multiply in your lotion and spoil your hard word.
Select several Mica powders to add to your bronzer, in shades that will complement your skin. Mica powder is sold in a variety of colors, from soft khaki colors to copper and bronze, to deep caramels. Choose one or two bronze colors, or select lighter or darker colors depending on your complexion. Add the Mica to the lotion in the bowl a teaspoon at a time, mixing between each addition. Add the Mica slowly until you reach a color that works well for your skin tone.
Cool the prepared bronzing lotion and store in a clean, empty bottle. Make sure the bottle seals completely so that air can not enter and dry out your lotion.
