If you've got problems with spending too much money on mascara, or having a hard time finding nontoxic ones, making your own homemade mascara recipe could be a solution for you.
Now, this recipe has not been tested by the FDA, but as long as you use ingredients that have been tested by the FDA, you should be perfectly okay. You basically just mix a pigment color (powdered eyeshadow) of your choice, with Aloe Vera gel.
You just use Aloe Vera gel and makeup pigments and mix them together 50/50 in whatever amount of mascara that you want to make. If you want to make an ounce, then you would use 1/2 ounce of gel, and 1/2 ounce of pigment.
The key is to find inexpensive ingredients to make your own mascara. Powdered eyeshadow can be pretty expensive right now, especially because mineral makeup is all the trend right now. But, if you go on any bulk makeup website, or any bulk makeup store that is catered especially to makeup artists and hair stylists, you should be able to find it pretty cheap.
The Aloe Vera gel should be even easier to buy in bulk, because it's really not that popular of a product in terms of trends. You can just find bulk Aloe Vera gel on tons of sites online that do provide it at an inexpensive cost.
If you become a pro at this, and successful enough, you can also add some FDA tested minerals and vitamins that you are certain can be used on the eyes. You definitely don't want to give yourself an eye infection.
And who know, if you get good enough, you could start your own line! You can simply just package your mascara in in empty mascara want and containers that can be purchased at any bulk makeup online store.
